It clamps transients at 22.5V maximum, with a 13.6V reverse standoff — sized for protecting 12V and 15V DC buses from surges up to 66.7A peak pulse current (10/1000µs waveform). The 1500W rating means it absorbs a single-pulse surge of that peak power without failing — the limiting factor in a real board is the trace inductance and the clamping voltage margin above the rail. With a 15.2V minimum breakdown, it triggers before the downstream regulator's abs-max is hit on a 12V bus. ## Through-hole package and temperature range Housed in a DO-201AA (DO-27) axial package, it mounts through-hole — the leads handle the surge current without the trace-lift risk of a surface-mount part on a thin copper pour. The single bidirectional channel protects both polarities of a differential pair or a single-ended rail against positive and negative transients — no need for two diodes in anti-series.","metaTitle":"Vishay 1.5KE16CA-E3/73 TransZorb TVS, 1500W, 22.5V Clamp","metaDescription":"Vishay 1.5KE16CA-E3/73 bidirectional TVS diode, 1500W peak pulse, 22.5V clamping, DO-201AA.
