Description
Transil diodes provide high overvoltage protection
by clamping action. Their instantaneous response
to transient overvoltages makes them particularly
suited to protect voltage sensitive devices such as
MOS Technology and low voltage supplied ICs.

1. The curves in Figure 5 are specified for a junction temperature of 25 °C before surge. The given results may be
extrapolated for other junction temperatures by using the following formula: VBR = T x [Tamb -25] x VBR(25 °C)
For intermediate voltages, extrapolate the given results.
