The reverse standoff voltage is 12.8V, meaning the diode begins conducting above that DC level and clamps transients to 22.26V maximum. Breakdown voltage range is 13.55V minimum, ensuring the device triggers before the protected circuit's absolute maximum rating is reached. Unidirectional — one channel, suited for DC rail protection where polarity is fixed. No power line protection rating, so it is not intended for AC mains surge suppression. ## Through-hole DO-201 axial — board-fit note Packaged in a DO-201AA / DO-27 axial leaded through-hole package, supplier device package DO-201. The through-hole mounting suits point-to-point wiring or PCB layouts where a soldered axial lead provides mechanical retention under vibration. Operating junction temperature range is -55°C to 175°C, covering industrial and under-hood automotive ambient conditions without derating.","metaTitle":"Littelfuse 1.5KE15 TVS Diode, 1500W, 12.8V Standoff","metaDescription":"Littelfuse 1.5KE15 Zener TVS diode, 1500W peak pulse, 12.8V standoff, DO-201.
