Protects From Load and 440VacIn AC Applications

Circuits

•

For 120Vac, 240Vac on Most IGBTs

•

Fits Terminal Spacing

•

Fast Clamping – Subnanosecond

These devices will protect your IGBT in applications where it is

used in overload protection or switching ac loads. Transient

voltages produced when switching occurs in the positive one-half

of the cycle are clamped below the destruct level of the IGBT.

Unique low inductance shunt path virtually eliminates L(di/dt)

effects. Available as screened device for high reliability

applications. Includes burn-in and environmental tests.
