5.0SMDJ Series
The 5.0SMDJ series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
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.
