We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...
To measure a zener diode’s breakdown voltage, you need a dc voltage source whose voltage exceeds that of the zener voltage. In Figure 1, resistor R SER provides voltage drop between V IN and V ZEN. In ...

How does a diode control electricity?
A diode is a tiny component that controls the flow of electricity by allowing current to pass in only one direction. This ...
Some diode manufacturers caution against using the diode tester function in ohmmeters because it could exceed the reverse-voltage and forward-current ratings of sensitive diodes. This is especially ...
When checking and verifying capacitors, inductors, diodes, bipolar transistors, and cables, the gamut of test methods can range from those used to confirm a defective component to identifying the ...
If you are using infrared (IR) hardware in an IoT, embedded, or mobile hardware project and are currently experiencing difficulties debugging IR communications, using one of the circuits shown below ...
Unlike filament lamps, where electrical energy must be converted into heat before light can be produced, Light Emitting Diodes (LEDs) are able to transform electrical energy directly into light energy ...
