Product Description
Taiwan Semiconductor SMBJ12A is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode built to protect electronic circuits by clamping voltage spikes. This TVS diode has a rugged surface mount DO-214 package, making it suitable for automated assembly processes.
With a peak pulse power dissipation rating of 600W, SMBJ12A is capable of handling significant transient events typically caused by electrostatic discharge (ESD), lightning, and inductive load switching. The device provides protection to sensitive electronics in industrial, automotive, and consumer electronic applications.
The diode features a minimum breakdown voltage of 13.3V and a maximum reverse stand-off voltage of 12V, making it ideal for 12V circuit protection. Its low clamping voltage of 19.9V minimizes potential damage to downstream components during transient surges.
Operating efficiently between temperatures of -55°C and 150°C, the SMBJ12A is designed for durability and reliability in harsh environments. It features a 2-pin configuration and measures compactly at 4.75mm length, 3.95mm width, and 2.45mm height, facilitating installation in space-constrained PCB designs.
Single diode configuration for focused voltage suppression. Uni-directional design protects circuits from positive voltage transients. Surface mount DO-214 package for easy PCB assembly. 600W peak pulse power dissipation rating ensures high energy absorption.
