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 specically to protect

sensitive electronic equipment from voltage transients

induced by lightning and other transient voltage events.
