STMicroelectronics 1-Element Uni-Directional TVS Diode 1.5 kW Peak Pulse Power 2-Pin DO-214 SMCJ30A-TR

STMicroelectronics SMCJ30A-TR is a single-element, uni-directional transient voltage suppression (TVS) diode designed to protect electronic circuits from voltage spikes and transients. Featuring a peak pulse power dissipation capability of 1.5 kW, this diode efficiently clamps high transient voltages to safe levels, enhancing the reliability of sensitive components in industrial, automotive, and consumer electronics systems.

The device is housed in a compact 2-pin DO-214 surface mount package, ensuring ease of integration into densely populated printed circuit boards (PCBs). The minimum breakdown voltage of 33.3 V and maximum reverse stand-off voltage of 30 V make it suitable for 30 V nominal working voltage circuits.

With a maximum peak pulse current rating of 156 A and clamping voltage of 64.3 V, the diode can absorb and safely divert significant transient energy. Its operating temperature range of -55°C to 150°C supports harsh environmental conditions encountered in automotive and industrial applications. The maximum reverse leakage current of 200 nA guarantees low leakage during normal operation, contributing to energy efficiency and circuit stability.

Physical dimensions of length 7.15 mm, width 6.25 mm, and height 2.45 mm provide a compact form factor compatible with automated assembly processes. The SMCJ30A-TR belongs to the SMCJxxA series, known for reliable transient voltage suppression performance.
