Surge Protection Zener Diodes

Toshiba Electronic Devices and Storage Corporation has released several Zener diode families. The CEZ, CUZ, MUZ, and MSZ series of Zener diodes protect from switching surges, inductive lightning surges, and electrostatic discharge (ESD).

Major types of electromagnetic noise such as transients and ESD can be damaging to electrical devices. In the power supply line, switching surges can reach thousands of volts with millisecond-long pulse widths during motor loading, hot-plug events, or short-circuits. ESD is a surge lasting hundreds of nanoseconds. Protecting against both types is critical.

Toshiba’s surge protection Zener diodes range from 5.6 V to 36 V in four different packages. In addition, their low dynamic resistance and low clamp voltages allow them to absorb surges well, reducing voltage surges on surrounding components in a variety of applications.
