SMBJ26A-Q Description

Short technical summary and product information.

The Bourns SMBJ26A-Q is a unidirectional transient voltage suppressor (TVS) diode designed for overvoltage protection in electronic circuits. It features a working peak reverse voltage of 26V and a maximum clamping voltage of 42.1V at a peak pulse current of 14.3A (10/1000μs). With a minimum peak pulse power dissipation of 600W (TP=1ms), it provides robust surge protection. The device can handle a peak forward surge current of 100A (8.3ms half sine wave) and boasts an ultra-fast response time of less than 1.0 picosecond from 0V to breakdown voltage.

 

This TVS diode is suitable for a range of applications including automotive, telecom, and industrial electronics. It is particularly useful for protecting power buses, I/O interfaces, and overvoltage transients. The device is AEC-Q101 qualified, making it suitable for automotive environments. It operates over a temperature range of -55°C to 150°C and can be stored under the same conditions.

 

Packaged in a surface mount DO-214AA (SMB) package, the SMBJ26A-Q is compatible with standard pick-and-place equipment. The SMB package offers a low profile and is easy to handle. The device is RoHS3 compliant and has UL recognition (File E153537).
