The breakdown voltage range starts at 11.4V minimum, so the diode does not conduct during normal 10.2V operation but fires well before the rail reaches damaging levels. ## Package and board-fit — DO-201 axial, through-hole mounting Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), the 1.5KE12A/B is a through-hole part intended for point-to-point wiring or PCB mounting with 0.050-inch lead spacing. The axial body sits flat on the board or can be formed for vertical insertion — common in crowded power-entry sections where a surface-mount TVS would not handle the pulse energy. The operating junction temperature range spans -55°C to +150°C, which covers both cold-start automotive environments and hot-side industrial enclosures without derating the 1500W pulse rating. ## Lifecycle and supply — active production, no obsolescence concern Sourced through authorized and independent distribution channels.","metaTitle":"YAGEO 1.5KE12A/B TVS Diode, 1500W, DO-201, 10.2V Standoff","metaDescription":"YAGEO 1.5KE12A/B Zener TVS diode, 1500W peak pulse, 10.2V reverse standoff, 16.7V clamp, DO-201 axial.
