Any replacement should match that grade if the application still requires it. ## Clamping performance and fit The reverse standoff voltage of 41.3 V means the diode stays transparent on a nominal 36 V or 40 V rail; it only starts conducting when the line exceeds that threshold. Housed in a DO-201AA (DO-27) axial-lead package — a through-hole form factor that requires a drilled PCB and hand or wave-solder assembly. The 1.5KE supplier device package code matches the axial body.","metaTitle":"Vishay 1.5KE51CHE3/73 TVS Diode, 1.5kW, 41.3V Standoff","metaDescription":"Obsolete Vishay 1.5KE51CHE3/73 1500W TransZorb® TVS diode, 41.3V reverse standoff, 73.5V clamp, AEC-Q101.
