A 344 V clamp at 4.4 A peak pulse means a 1500 W surge (10/1000 µs) is limited to that voltage; downstream components must withstand that clamp level for the pulse duration.","metaTitle":"Vishay 1.5KE220HE3/73 Zener, 1.5kW, 175V, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE220HE3/73 Zener TVS, 1500W peak pulse, 175V reverse standoff, AEC-Q101.
