8.0SMDJ Series
Surface Mount – 8000W
Agency Agency File Number
E230531
The 8.0SMDJ series is designed specifically to protect sensitive
electronic equipment from voltage transients induced by lightning
and other transient voltage events.
TVS components are ideal for the protection of I/O Interfaces, VCC
bus and other vulnerable circuits used in Telecom, Computer,
Industrial and Consumer electronic applications.
