SMBJ28CA Description

Short technical summary and product information.

The SMBJ28CA is a bidirectional transient voltage suppressor (TVS) diode from Littelfuse, designed to protect sensitive electronics from voltage transients. It is part of the SMBJ series, known for its compact surface mount package and 600W peak pulse power capability.

 

Electrical specifications: reverse standoff voltage of 28V (nominal), minimum breakdown voltage of 31.1V, and maximum clamping voltage of 45.4V at peak pulse current. It can handle peak pulse currents up to 13.3A (10/1000µs waveform) and dissipates 600W peak pulse power. The device operates over a junction temperature range of -65°C to 150°C.

 

Packaged in a DO-214AA (SMB) surface mount package, it is suitable for automated assembly and space-constrained designs. The SMBJ28CA is claimed RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited). Compliance data is unverified and should be confirmed with the latest manufacturer documentation.
