STMicroelectronics 1-Element Bi-Directional TVS Diode 600 W, Surface Mount, DO-214 Package SMBJ28CA-TR

STMicroelectronics SMBJ28CA-TR is a 1-element bi-directional Transient Voltage Suppressor (TVS) diode engineered to protect electronic devices from voltage transients and electrostatic discharge. Rated at 600 W peak pulse power dissipation, this diode offers robust surge protection in a compact DO-214 surface mount package, suitable for modern industrial and electronic assemblies.

Featuring single element configuration for bi-directional voltage suppression, the device has a minimum breakdown voltage of 31.1 V and a maximum reverse stand-off voltage of 28 V, which enable precise clamping of potentially damaging voltage spikes up to a clamping voltage of 59 V. Its low leakage current of 200 nA ensures minimal impact on normal circuit operation. Designed to operate reliably from -55°C to 150°C ambient temperature, the SMBJ28CA-TR is ideal for demanding environments such as power supplies, industrial controls, and communication equipment.

Its compact dimensions (L=4.6 mm, W=3.95 mm, H=2.45 mm) and surface mount design allow streamlined PCB integration without compromising board space. The 2-pin DO-214 package simplifies assembly and soldering, increasing manufacturing efficiency.

This diode is part of the SMBJ series, well-known for consistent performance in transient voltage suppression applications. It withstands peak pulse currents up to 68 A, effectively clamping voltage surges and protecting critical semiconductor components from damage.

Applications include industrial electronics, automotive electronics protection circuits, telecommunications, and any systems requiring voltage transient safeguarding. Its rugged design supports industrial, laboratory, and manufacturing environments where reliable power transient suppression is mandatory.
