That 698 V clamp is the ceiling the downstream circuitry must survive — a power supply or MOV rated for 700 V+ gives you margin. ## Through-hole DO-201 — board-fit and thermal path Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE510A-B mounts through-hole, with the cathode band marking the unidirectional orientation.","metaTitle":"1.5KE510A-B Littelfuse TVS Diode, 1500W, DO-201","metaDescription":"Littelfuse 1.5KE510A-B Zener TVS, 1500W peak pulse, 434V standoff, 698V clamp.
