Zener Diodes

A Zener diode is characterized by its ability to protect an object from transient overvoltage pulses as well as overvoltage pulses close to DC, which are difficult to protect against with ESD protection diodes.
In equipment power lines, switching surges with long pulse widths up to milliseconds may be generated when the circuit switches. Zener diodes protect semiconductor devices from switching surges and overvoltage with a frequency close to DC. It can also protect semiconductor devices from ESD[2] with a width of several hundred nanoseconds and inductive lightning surges[1] with a pulse width in the order of microseconds as well. This contributes toward improved equipment reliability.
Zener diodes are available in a wide range of Zener voltage specifications extending from 5.6 V to 82 V. Their extensive application fields include both consumer and industrial electronics.
