Notes

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute maximum ratings for extended periods of the time can adversely affect reliability.

(1) Wave soldering three cycles are allowed. Also refer to “Assembly Instruction”.

TCLT1014 FAQ

What is an Optocoupler?

An optocoupler (also called optoisolator) is a semiconductor device that allows an electrical signal to be transmitted between two isolated circuits. Two parts are used in an optocoupler: an LED that emits infrared light and a photosensitive device that detects light from the LED.

 

Is optocoupler and optoisolator same?

Industrial terminology often blurs the lines between similar terms. Today we find that both the terms optocoupler and optoisolator are used interchangeably to refer to the same function. The distinguishing feature between these two terms is the amount of voltage being isolated.

 

What are the 4 types of optocoupler?

Depending on the use there are mainly four types of optocouplers are available.

  • Opto-coupler which use Photo Transistor.
  • Opto-coupler which use Photo Darlington Transistor.
  • Opto-coupler which use Photo TRIAC.
  • Opto-coupler which use Photo SCR.

 

Which circuit uses photo Darlington devices?

The photo-transistor and photo-darlington devices are mainly for use in DC circuits while the photo-SCR and photo-triac allow AC powered circuits to be controlled. There are many other kinds of source-sensor combinations, such as LED-photodiode, LED-LASER, lamp-photoresistor pairs, reflective and slotted optocouplers.

 

Where are optocouplers used?

Optocouplers are extensively used in electronics, electrical, and communications systems. Optocouplers are often used to reject back EMF, noise, and electrical surges from entering an MCU circuit.
