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.
