Transient Voltage Suppression (TVS) Diodes
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.
1500 WATT AXIAL TRANSIENT VOLTAGE
SUPPRESSORS
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, VCC bus, and other integrated
circuits used in telecom, computer, datacom,
and industrial electronics.
FEATURES
• Glass passivated junction
• Stand-off voltage range: 6.8 -400 V
