Taiwan Semiconductor 1-Element Uni-Directional TVS Diode, 1.5 kW, 2-Pin DO-214 SMCJ40A

Taiwan Semiconductor SMCJ40A is a 1-element Uni-Directional Transient Voltage Suppression (TVS) diode designed for protecting sensitive electronics from voltage spikes and transient surges. It provides robust surge protection with a peak pulse power dissipation rating of 1.5 kW, making it suitable for power and signal line protection in industrial and consumer electronics.

This diode uses a surface mount DO-214 package, offering convenience in automated PCB assembly processes. Its maximum reverse stand-off voltage is 40 V, with a clamping voltage of 64.5 V, ensuring effective suppression of transient voltage that can damage electronic components. The device features a small footprint with 7.15 mm length, 6.25 mm width, and 2.75 mm height dimensions, suitable for compact circuit layouts.

The device maintains excellent performance over a wide temperature range from -55°C (minimum operating temperature) to 150°C (maximum operating temperature). Its low reverse leakage current of 5 μA minimizes power loss during normal operation. With a peak pulse current rating of 23.3 A and a glass-passivated junction, it offers fast response time and enhanced reliability.

Typical applications for the SMCJ40A include transient protection in power supplies, automotive electronics, automotive systems, industrial controls, telecommunications equipment, and other electronic circuits sensitive to voltage spikes. It effectively safeguards circuits against damage caused by electrostatic discharge (ESD), lightning transients, and inductive load switching.

Set in the Taiwan Semiconductor SMCJ series, this diode complies with relevant technical and quality standards and is specifically engineered for industrial and manufacturing circuit protection requirements. Its 2-pin configuration simplifies integration into various electrical devices.
