Its 43.6V reverse standoff voltage protects 48V nominal rails, with a breakdown range of 48.5V min and a clamping ceiling of 70.1V at the 21.4A peak pulse current (10/1000µs waveform). ## DO-201AA axial package for through-hole assembly The DO-201AA (DO-27) axial leaded package mounts through-hole, which suits high-reliability board attachment in power distribution and ECU modules. The package body handles the 1500W pulse without cracking, and the axial leads carry the surge current with low inductance.","metaTitle":"Vishay 1.5KE51AHE3_A/C TVS Diode, 1500W, 43.6V Standoff","metaDescription":"Vishay 1.5KE51AHE3_A/C automotive TVS diode, 1500W peak pulse, 43.6V standoff, AEC-Q101, DO-201AA axial.
