DESCRIPTION

Transil diodes provide high overvoltage protection

by clamping action. Their instantaneous response

to transient overvoltages makes them particularly

suited to protectvoltage sensitive devices such as

MOSTechnologyand low voltage supplied IC’s.

Note : The curves of the figure 3 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 : ∆V (BR) = αT (V(BR)) * [Ta -25] * V (BR).
