The clamping voltage of 328 V at 4.8 A peak pulse current defines the maximum voltage the downstream circuitry sees during a surge. For a 1500 W pulse, the clamping factor (Vc / Vbr) is about 1.57 — typical for a Zener TVS in this power class. The DO-201 axial package requires a lead bend and through-hole solder joint; the anode band identifies the cathode end for unidirectional orientation. Bulk packaging suits manual or wave-solder assembly lines. The AEC-Q101 qualification and automotive grade make it a direct fit for under-hood and chassis-domain protection circuits.","metaTitle":"1.5KE220AHB0G TVS Diode, 1500W, DO-201, AEC-Q101","metaDescription":"1.5KE220AHB0G Zener TVS diode, 185V standoff, 328V clamp, 1500W peak pulse, AEC-Q101 automotive grade, DO-201 axial, active.
