8.0SMDJ Series 22 To 36 V 8000W
SOCAY Electronics Co., Ltd. www.socay.com
The 8.0SMDJ series is designed specifically to protect sensitive
electronic equipment from voltage transients induced by lightning
and other transient voltage events.
Uni-directional Bi-directional
u Glass passivated chip
u Low leakage
u Uni and Bidirectional unit
u Excellent clamping capability
u 8000W Peak power capability at 10 × 1000µs waveform
Repetition rate (duty cycle):0.01%
u Very fast response time
u RoHS compliant
TVS devices are ideal for the protection of I/O interfaces, V
CC
bus
and other vulnerable circuits used in Telecom, Computer, Industrial
and Consumer electronic applications.
