This semiconductor diode tester circuit using a 741 Integrated Circuit. It can test whether a semiconductor diode is in good condition and also determines its polarity.
The Photodiode – Light detector diode Photodiode looks similar to the common LED, but it has a feature that makes it very special. It is a device that converts light into current. Incident Light (red arrows). Direction of the generated current (blue arrow). This current flows on the opposite direction of the arrow of the diode and […]
What is a Zener diode? The Zener diode is a special type of diode that allows the flow of the current to run on the opposite direction of the arrow of the diode. This diode does not conduct until the applied voltage reaches or is greater of the breakdown voltage. This is the “zener voltage”. Note: The zener diode behaves like a common semiconductor […]
