SMBJ12A Description

Short technical summary and product information.

The SMBJ12A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Liown. This component is designed to protect sensitive electronic circuits from voltage transients, such as those caused by electrostatic discharge (ESD) or lightning.

 

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 at a peak pulse current of 30.2A (10/1000 S waveform). The diode is housed in a compact SMB (DO-214AA) package, suitable for surface mount applications.

 

This TVS diode is suitable for various protection applications where reliable suppression of transient overvoltages is required. Its unidirectional nature makes it ideal for protecting against positive voltage transients.
