Polarity and Pinout

The 1N4148WS diode has a cathode (-) and anode (+). In the schematic symbol, the tip of the triangle with the line on top of it is the cathode. The cathode is marked on the body of a diode by a band as shown below.

 

 

The current can flow from only the anode to the cathode and never from the cathode to the anode - the 1N4148WS diode is like a one way electric valve.

FAQ

What are Schottky diodes used for?

Schottky diodes are used for their low turn-on voltage, fast recovery time and low-loss energy at higher frequencies. These characteristics make Schottky diodes capable of rectifying a current by facilitating a quick transition from conducting to blocking state.

 

Are all 1N4148 diodes the same?

As the most common mass-produced switching diode, the 1N4148 replaced the older 1N914. They differed mainly in their leakage current specification, however, today most manufacturers list common specifications. For example, Vishay lists the same leakage current for both parts: 25 nA at -20 V, 25°C.

 

What is 1N4148WS-7-F diode?

The 1N4148WS-7-F is a surface mount silicon epitaxial planar fast Switching Diode for general purpose switching, high speed switching applications. It is ideally suited for automatic insertion. 75V DC Reverse voltage. -65 to 150°C Junction and storage temperature range.
