SMBJ12A-TR Description

Short technical summary and product information.

The SMBJ12A-TR is a unidirectional TVS (Transient Voltage Suppression) diode designed by STMicroelectronics for general-purpose circuit protection. It is rated for a peak pulse power dissipation of 600W and can handle peak pulse currents up to 31A.

 

With a reverse standoff voltage of 12V and a clamping voltage of 19.9V, this diode provides effective protection against voltage transients. It is a single-channel, unidirectional device and does not include power line protection features.

 

The device is housed in a surface-mount DO-214AA (SMB) package, suitable for automated assembly. It operates over a wide temperature range from -55°C to 150°C.

 

The SMBJ12A-TR is intended for general-purpose applications where transient voltage suppression is required. It is listed as RoHS3 compliant and REACH unaffected, with an MSL rating of 1 (unlimited).
