1. What is zener diode. 2. If you belongs to wiring harness so interviewer will ask about wiring harness. 3. What is relay and use. 4. What is fuse and its type. 5. What is PPAP,DFM and DFMEA.

Question

Accepted Answer

A zener diode is a type of diode that allows current to flow in the forward direction like a normal diode, but also in the reverse direction when the voltage reaches a certain threshold.

Zener diodes are commonly used for voltage regulation and overvoltage protection in electronic circuits.
They have a specific breakdown voltage, known as the zener voltage, at which they start conducting in the reverse direction.
Zener diodes are often used in voltage regulator circuits to maintain a constant output voltage.
They are also used in surge protectors to divert excess voltage away from sensitive components.
