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-E series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
