Product details

12V bidirectional TVS — 600W peak pulse, 19.9V clamp

The SMBJ12CAQ-13-F: This is a Zener-type bidirectional TVS diode: the 12V reverse standoff voltage (V_RWM) means it sits across a 12V rail and stays transparent until a transient exceeds 13.3V breakdown (minimum). The device absorbs 600W peak pulse power, which covers common automotive load-dump and ESD events.

DO-214AA (SMB) surface-mount package

The SMBJ12CAQ-13-F comes in the DO-214AA (SMB) package, a standard surface-mount footprint for TVS diodes rated up to 600W. The supplier device package is also SMB.
