Features
• ^{Protects From Load Switching In AC Applications}
• ^{For 120Vac, 240Vac and 440Vac Circuits}
• ^{Fits Terminal Spacing on Most IGBTs}
• ^{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.
