The reverse standoff voltage is 43.6V, with a minimum breakdown of 48.45V. This window means the diode stays high-impedance below 43.6V and begins conducting between 48.45V and 70.1V — the rail must never exceed 43.6V in normal operation, or the diode leaks and eventually clamps. ## Package and board integration Through-hole DO-201AA / DO-27 axial package (supplier device package DO-201). The axial leads suit point-to-point wiring or PCB through-hole mounting — the body diameter and lead spacing are standard for this power class, so the footprint matches existing 1.5KE-series layouts without a board spin. This covers industrial and military-grade environments — the diode's leakage and clamping characteristics shift with temperature, but the 150°C max junction means it survives sustained high ambient in enclosures or near hot rails.","metaTitle":"1.5KE51A-G TVS Diode, 1500W, 70.1V Clamp, DO-201","metaDescription":"Comchip Technology 1.5KE51A-G Zener TVS diode, 1500W peak pulse, 70.1V clamping, 43.6V standoff, DO-201 axial.
