Applications

TVS devices are ideal for the protection of I/O Interfaces,

VCC bus and other vulnerable circuits used in Telecom,

Computer, Industrial and Consumer electronic

applications.

The P4SMA series is designed speciﬁcally to protect

sensitive electronic equipment from voltage transients

induced by lightning and other transient voltage events.
