How to distinguish a 1N4148 diode from a Zener diode visually?

WebZener Diode. It is the most useful type of diode as it can provide a stable reference voltage. These are operated in reverse bias and break down on the arrival of a certain voltage. If current passing through the resistor is limited, a stable voltage is generated. Zener diodes are widely used in power supplies to provide a reference voltage. WebJan 20, 2024 · Generally you can tell because a 1N4148 is typically marked '1N4148' on the body, while a Zener diode has a different marking. You may need a magnifying glass to make sure though, because other diodes can have quite similar markings. If the markings are partially rubbed off it might be difficult to tell the difference. WebTesting of Zener Diode with a multimeter The first step is to Identify Zener diode anode and the cathode. After identifying the anode and cathode of the Zener diode, Place your multimeter’s knob to voltage mode. After that, you need to connect your multimeter probes to the Zener diode. chiropodist in peterborough
