With a 19.9V maximum clamping voltage at 20.1A peak pulse current, the TVS holds a 12V supply bus below the typical 24V abs-max of downstream ICs. The 400W rating is the peak pulse power at the 10/1000µs test waveform — a shorter pulse (e.g. 8/20µs) allows higher peak current before the device reaches its thermal limit. The bidirectional channel (single device) protects signal pairs or power rails that swing both sides of ground — no need to orient the diode or worry about reverse insertion.","metaTitle":"SMAJ12CAQ-13-F TVS Diode, 12V Bidirectional, 400W, DO-214AC","metaDescription":"SMAJ12CAQ-13-F bidirectional TVS diode, 12V standoff, 400W peak pulse, AEC-Q101 automotive grade.
