TRANSIL^TM
DESCRIPTION
Transil diodes provide high overvoltage protection
R6
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_amb = 25°C)
Symbol
Parameter
P_PP
Peak pulse power dissipation (see note 1)
Tj initial = T_amb
P
Power dissipation on infinite heatsink
T_amb = 75°C
I_FSM Non repetitive surge peak forward current
for unidirectional types
tp = 10ms
Tj initial = T_amb
T_stg Storage temperature range
T_j
Maximum junction temperature
T_L
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.
