TRANSIL^TM
DESCRIPTION
Transil diodes provide high overvoltage protection
AG
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.
ABSOLUTE MAXIMUM RATINGS (Tamb = 25°C)
Symbol
Parameter
PPP Peak pulse power dissipation (see note 1)
Tj initial = Tamb
P
Power dissipation on infinite heatsink
T_amb = 75°C
IFSM Non repetitive surge peak forward current
for unidirectional types
tp = 10ms
Tj initial = T_amb
Tstg Storage temperature range
T_j
Maximum junction temperature
TL
Maximum lead temperature for soldering during 10s at 5mm
from case
Note 1 : For a surge greater than the maximum values, the diode will fail in short-circuit.
