Introduction

A diode is a common PN junction semiconductor device in the realm of microelectronics. Because it is made of P and N components. It functions as a one-way switch, allowing current to flow in one direction while stopping it in the other.

1N4007 diode is a member of the silicon family of the 1N400X series. It is a general-purpose rectifying diode that converts alternating current signals (AC) to direct current signals (DC) in electrical goods.

This tutorial will discuss its pinout, features, specifications, example circuits, and applications.

Ⅰ What is the 1N4007 Diode?

The IN4007 diode is a device that only enables electricity to travel in one way. In other words, the current should always travel from anode to cathode. The maximum current carrying capacity of the 1N4007 diode is 1A, and it can endure peaks of up to 30A.

Because these diodes only allow electrical current to travel in one direction, they are used to convert alternating current (AC) to direct current (DC). When building a rectifier, it is critical to use the proper diode for the purpose; otherwise, the circuit may be damaged.

The logic symbol pinout of 1N4007 diode

 

When the voltage at the anode exceeds the voltage at the cathode, the diode is said to be "forward-biased," because the electrical current is "flowing forward." In a forward-biased state, the highest amount of current that the diode can stably conduct is 1 ampere.

Theoretically, when the voltage at the cathode exceeds the voltage at the anode, the diode will not conduct an electrical current. In actuality, the diode conducts a tiny current under these conditions. If the voltage differential becomes large enough, the current through the diode will increase and the diode will fail.

2.2 Revere Recovery Time

1N4007, like other diodes, requires a reverse recovery time to recover after switching from forward to reverse biased mode. During reverse recovery, the diode generates a large reverse current, which generates heat. The higher the frequency of the input signal, the longer it takes the diode to restore its condition. Because of its long recovery period, 1N4007 is a low-frequency diode. As a result, it should only be used for low-frequency applications.

 1N4007 Diode Example Circuit

In this part, we will look at a few 1N4007diode sample circuits:

6.1 1N4007 in Forward and Reverse Biased Mode

The 1N4007 diode is said to be forward-biased when the input voltage applied to the anode terminal is greater than the input voltage applied to the cathode terminal. When the provided input voltage exceeds 0.6 volts, the IN4007 diode short circuits. The forward drop voltage of 1N4007 is 0.6V.

The following proteus simulation is a superb demonstration of the diode switching concept:

1N4007-in-rorward-and-reverse-biased-mode

The two circuits represent the diode's states. The first circuit depicts the diode in its forward-biased state. The anode is linked to the power supply, while the cathode is linked to the ground. As a result, the anode of the diode has a higher potential than the cathode, allowing the current to exceed its depletion region. The LED lights as current travels through it.

The second circuit, on the other hand, shows the reverse-biased scenario, in which current cannot flow due to a depletion region and the LED does not glow.

6.2 1N4007 as a Voltage Regulator

This circuit shows how to utilize 1N4007 diodes as a voltage regulator. The schematic depicts a voltage regulator:

1N4007-as-a-voltage-regulator

A diode has a depletion area, and as it passes through the barrier, the voltage drops by 0.6 Volts. Using this potential drop, we may create a voltage regulator that meets our needs.

Ten 1N4007 diodes are connected back-to-back in series to generate 3 volts from a 9-volt power supply. When forward current flows from the first diode through an anode to cathode terminal, the voltage across the first diode reduces by 0.6V, and the input voltage for a second diode is 9-0.6 = 8.4v. A similar process occurs for each diode, and the input voltage progressively decreases from 9 Volts to the required 3 Volts, allowing it to be used to power any electronic device that requires 3V.

This is not a recommended design for real-world projects, but the example circuit is provided to demonstrate the use of the 1N4007 diode.

 How Does 1N4007 Diode Work?

ON Semiconductor's 1N4007 is a general-purpose diode. It's common in rectifier and power supply applications. These diodes' compact form size makes them appropriate for space-constrained applications. The circuit below is a complete bridge diode rectifier circuit that converts AC voltage to DC voltage. The complete bridge is made up of four diodes that switch on and off at regular intervals during the positive and negative half cycles of the alternating current voltage to produce a DC signal at the rectifier output.

 How to Test a 1N4007 Diode

A 1N4007 diode is a type of electrical component that permits current to flow in just one direction. When the current reverses direction, the diode stops it. The 1N4007 diode is a compact, general-purpose device capable of handling currents up to 1 amp and voltages up to 1000 volts. A diode, like any other electrical component, can fail. It may either fail to open and conduct current in either way, or it might short and conduct current in both directions. In addition, the diode may leak significantly in the opposite direction. A multimeter, a battery, and a low-value resistor can be used to test a 1N4007 diode.

  • A diode is a type of electrical component that permits current to flow in just one direction.

Examine the 1N4007 diode attentively and note the presence of a white ring on one end of the device. This denotes the cathode end of the diode. The anode is at the other end.

  • Examine the 1N4007 diodeattentively and note the presence of a white ring on one end of the device.

Turn on the multimeter and adjust the function knob to read resistance. Check that the black probe wire is plugged into the meter's common, or negative, socket and the red probe is plugged into the positive socket.

Connect the black probe of the multimeter to the cathode lead of the 1N4007. This is the banded or striped side. Connect the red probe to the anode lead of the diode. Wrapping the diode's leads around the probe tips may be convenient. Touching the probe tips or leads with your fingers can distort the meter's reading since your body's resistance will distort the reading. The meter should display 0 or an extremely low value, such as 1 ohm. If you read a high resistance, the diode has internally cracked open, therefore discard it.

Reverse the probe wires on the diode so that the black probe touches the anode lead and the red probe touches the cathode. The meter should now show an extremely high resistance. The meter may display "OL" for overload or something similar to indicate a resistance that is too great for the meter to read. If the resistance is exceedingly low, the diode is shorted and thus faulty.

  • Reverse the probe wires on the diode so that the black probe touches the anode lead and the red probe touches the cathode.

Remove the diode from the probe tips of the meter. Select DC milliamps (thousandths of an amp) or microamps on the meter's selector knob (millionths of an amp). Wrap or crimp one lead of the 470-ohm resistor to the positive terminal of an AA battery clip. Connect the cathode lead of the diode to the free lead of the resistor. Wrap the anode around the positive probe tip of the multimeter. Connect the meter's negative probe tip to the negative terminal of the battery clip. Insert a new AA battery into the clip. A current reading of no more than 5 microamps should be obtained. If the meter reads substantially higher than this, the diode is faulty and should be replaced.
