SMBJ12A Description

Short technical summary and product information.

The SMBJ12A from ST is a unidirectional Transient Voltage Suppressor (TVS) diode. It is designed to protect sensitive electronic components from electrostatic discharge (ESD) events.

 

Key electrical specifications include a 12V reverse standoff voltage (Vrwm), a minimum breakdown voltage of 13.3V, and a maximum clamping voltage of 19.9V when subjected to a peak pulse current of 30.2A (10/1000 S waveform).

 

This TVS diode is housed in a surface-mount SMB (DO-214AA) package, making it suitable for integration into compact electronic designs. Its unidirectional nature means it provides protection in one direction.

 

The SMBJ12A is RoHS3 compliant and has an MSL rating of 1, indicating unlimited shelf life under recommended storage conditions.
