Frequently Asked Questions
1.How do you read numbers on a diode?
The "1" identifies the component as a diode. The "N" shows the material in the device is a semiconductor. Decode the model code. The number after the diode and material-designation codes is the model or part number.
2.What happens if you put a diode in backwards?
Reverse bias usually refers to how a diode is used in a circuit. If a diode is reverse biased, the voltage at the cathode is higher than that at the anode. Therefore, no current will flow until the electric field is so high that the diode breaks down.
3.How does a diode behave in a circuit?
Current passing through a diode can only go in one direction, called the forward direction. Current trying to flow the reverse direction is blocked. They're like the one-way valve of electronics. If the voltage across a diode is negative, no current can flow, and the ideal diode looks like an open circuit.
