The -55°C to +175°C operating junction temperature range covers under-hood thermal extremes, and the DO-201AA axial-lead package (DO-27 variant) allows through-hole mounting for high-reliability connections in vibration-prone assemblies.","metaTitle":"Vishay 1.5KE27AHE3_A/D TVS, 1500W, 23.1V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE27AHE3_A/D Zener TVS, 1500W peak pulse, 23.1V reverse standoff, DO-201AA axial.
