SMBJ30A Description

Short technical summary and product information.

The Bourns SMBJ30A is a unidirectional transient voltage suppressor (TVS) diode designed for surge and ESD protection. It features a reverse standoff voltage of 30V and a breakdown voltage of 33.3V (min). The clamping voltage is 48.4V at a peak pulse current of 12.4A (10/1000µs waveform). With a peak pulse power rating of 600W, it provides robust protection against transient overvoltages.

 

This TVS diode is suitable for general purpose applications including IEC 61000-4-2 ESD, IEC 61000-4-4 EFT, and IEC 61000-4-5 surge protection. It is not intended for power line protection.

 

The device is housed in a DO-214AA (SMB) surface mount package, with an operating temperature range of -55°C to 150°C. It is RoHS compliant and has an MSL rating of 1 (unlimited).
