SMBJ28CA Description

Short technical summary and product information.

The Bourns SMBJ28CA is a bidirectional Zener-type transient voltage suppressor diode designed for general purpose circuit protection. It features a reverse standoff voltage of 28V, a minimum breakdown voltage of 31.1V, and a maximum clamping voltage of 45.4V at a peak pulse current of 13.3A. With a peak pulse power rating of 600W (10/1000µs waveform), it provides robust protection against voltage transients.

 

This TVS diode is housed in a surface mount DO-214AA (SMB) package, suitable for automated assembly. It operates over a junction temperature range of -55°C to 150°C. The device is compliant with IEC 61000-4-2 ESD (Level 4), IEC 61000-4-4 EFT, and IEC 61000-4-5 surge standards, making it suitable for portable communications, computing, and video equipment.

 

The SMBJ28CA is part of the Bourns SMBJ series, offering a wide selection of standoff voltages from 5V to 495V. Its bidirectional configuration allows protection of circuits where polarity is not fixed. The fast response time (typically <5ps for bidirectional devices) ensures minimal stress on protected components.
