UNI AND BIDIRECTIONAL TYPES

LOW CLAMPING FACTOR

FAST RESPONSE TIME

UL RECOGNIZED

DESCRIPTION

Transil diodes provide high overvoltage protection

by clamping action. Their instantaneous response

to transient overvoltages makes them particu-

larly suited to protect voltage sensitive devices

such as MOS Technology and low voltage sup-

plied 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 _*(T_amb-25) _*V_BR(25°C).

For intermediate voltages, extrapolate the given results.
