The reverse standoff voltage is 427.5V, meaning the diode stays high-impedance below that level and only starts conducting when the transient exceeds it. For a 400V nominal rail, this gives about 27V of headroom before the TVS begins to clamp — typical for protecting MOVs or downstream DC-DC converters in industrial power supplies. Housed in a DO-201AA / DO-27 axial leaded package, the 1.5KE500A-G is a through-hole part — the leads go through the board and are soldered on the opposite side. The DO-201 footprint is standard; the anode end is usually marked with a band. For a repair tech, this package is easy to extract and replace with a soldering iron or hot-air station, unlike surface-mount TVS arrays that need reflow.","metaTitle":"Comchip 1.5KE500A-G Zener TVS, 1500W, DO-201","metaDescription":"1.5KE500A-G Zener TVS diode, 1500W peak pulse power, 427.5V standoff, 690V clamping.
