SA78A-B

瞬态电压抑制二极管 Transient Voltage Suppression Diodes

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.
