SMBJ12A Description

Short technical summary and product information.

The Vishay Dale SMBJ12A is a unidirectional Transient Voltage Suppressor (TVS) diode. It is designed to protect sensitive electronic components from transient overvoltage events, particularly electrostatic discharge (ESD).

 

Key electrical characteristics include a reverse standoff voltage of 12V, 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 makes it suitable for applications requiring robust protection against voltage spikes.

 

The SMBJ12A is packaged in a standard SMB (DO-214AA) surface-mount case, facilitating integration into compact electronic designs. Its construction is suitable for automated assembly processes.

 

This TVS diode is classified under RoHS3 compliance and has a Moisture Sensitivity Level (MSL) of 1, indicating it is suitable for general electronic applications.
