No pin-compatible drop-in replacement from Littelfuse is documented. Housed in a DO-201AD axial-lead package, the 1.5KE20AG mounts through-hole — the lead bend and board hole pattern follow standard axial diode land patterns. Operating junction temperature range spans -65°C to 175°C, covering industrial and automotive under-hood thermal profiles without derating.","metaTitle":"1.5KE20AG Littelfuse Mosorb™ TVS, 1.5kW, 17.1V Standoff","metaDescription":"Littelfuse 1.5KE20AG Mosorb™ Zener TVS, 1500W peak pulse, 17.1V reverse standoff, DO-201AD axial.
