DESCRIPTION

Description

OVERVIEW

Product Overview

The SMAJ12A is a unidirectional transient voltage suppression (TVS) diode from CYStek in an SMA (DO-214AC) surface-mount package. It conducts rapidly when circuit voltage exceeds the threshold, diverting transient energy to protect downstream sensitive components from overvoltage damage. The unidirectional structure suits DC power or unidirectional signal line protection, and is widely used for surge protection in consumer electronics, communication equipment and industrial control boards. The SMA package is small and easy to place in compact layouts. Refer to the official datasheet for specific electrical parameters.

APPLICATIONS

Applications

  • Used for overvoltage protection at DC power inputs.
