SMAJ14CA Bidirectional TVS Diode – 14V Transient Suppressor (SMA Package)

Product Description:
The SMAJ14CA TVS Diode is a robust bidirectional transient voltage suppressor designed to protect sensitive electronics from voltage spikes caused by lightning, inductive load switching, ESD, and other transient surges. Built in a compact SMA (DO-214AC) surface-mount package, this diode provides excellent protection for 14V-powered circuits, ensuring stable and reliable operation of ICs, MOSFETs, and sensitive signal lines.

With a reverse stand-off voltage of 14V, a breakdown voltage up to 17.2V, and a maximum clamping voltage of 23.2V, the SMAJ14CA effectively absorbs high-energy transients with a peak pulse current of 25.8A. It offers ultra-fast response time (typically <1ps), exceptional clamping performance, and high surge capability, making it ideal for industrial, automotive, telecom, and consumer electronics.

Designed for surface-mount applications, this TVS diode features built-in strain relief, low profile packaging, and excellent thermal stability, providing long-term durability even in harsh operating environments.
