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.

ABSOLUTE MAXIMUM RATINGS (T

Note 1 : For a surge greater than the maximum values, the diode will fail in short-circuit.
