Silicon Avalanche Diodes
500 Watt Axial Leaded Transient Voltage Suppressors
RoHS SA Series
®
The SA Series is designed specifically to protect sensitive
electronics equipment from voltage transients induced by
lightning and other transient voltage events. These devices are
ideal for the protection of I/O interfaces, Vcc bus and other
vulnerable circuits used in computer and consumer electronic
applications.
