FAST RESPONSE TIME
UL RECOGNIZED
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 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 :
∆VBR = αT * [Tamb -25] * VBR(25°C).
For intermediate voltages, extrapolate the given results.
