Invisible Protection
When no problems exist, Crydom TVS
Diodes are totally invisible to the circuits
they're protecting. But when potentially
damaging transients occur, they provide
high-speed "clamping" to prevent damage
– and then return to their electronically
invisible state.
MAXIMUM RATINGS
• Peak pulse power (P
PK
):
1500 watts (10 X 1000 µs)
• 5 watt steady state
• Response time: 1 X10
-12
s (theoretical)
• Forward surge rating: 200 A, 8.3 ms half
sine wave (uni-directional devices only)
• Operating and storage temperature:
-55°C to +175°C
1500 WATT AXIAL TRANSIENT VOLTAGE
SUPPRESSORS
MECHANICAL CHARACTERISTICS
Protect sensitive electronics against voltage
transients induced by electrostatic dis-
charge (ESD), inductive load switching,
and lightning. Ideal for the protection of I/O
interfaces, V
CC
bus, and other integrated
circuits used in telecom, computer, datacom,
and industrial electronics.
FEATURES
• Case: Molded plastic over glass
passivated junction
• Terminals: Axial leads, solderable
per MIL-STD-202 Method 208
• Marking: Cathode band (positive
terminal, uni-directional devices
only), device code, logo
• Weight: 1.2 grams (approx.)
• Glass passivated junction
• Stand-off voltage range: 6.8-400 V
• Low clamping factor
• Uni-directional and bi-directional
• 100% surge tested
• UL listed
