Breakdown occurs at a minimum of 209V, and the clamping voltage at the 4.6A peak pulse current (10/1000µs waveform) is 328V max. This window protects a 185V DC bus — typical in automotive 24V systems after a boost stage — from load-dump and inductive surge transients. Peak pulse power is rated at 1500W (1.5kW) for the 10/1000µs waveform, which covers the surge energy from a 24V alternator load dump or a relay-coil kickback on the same rail. ## Through-hole axial package, one unidirectional channel The single unidirectional channel clamps only one polarity, so the cathode band must be oriented toward the protected rail. Power line protection is not supported (the diode is unidirectional and not designed for AC mains clamping), so it is best applied on DC power or signal lines where the polarity is fixed.","metaTitle":"1.5KE220AHE3_A/D Vishay TVS Diode, 1500W, AEC-Q101","metaDescription":"Active Vishay 1.5KE220AHE3_A/D TransZorb® TVS, 1500W peak pulse, 185V standoff, AEC-Q101 qualified.
