That 30 V window between standoff and clamp gives the downstream circuitry a defined survival envelope. ## Package and temperature range Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE51C is a through-hole part suited for point-to-point wiring or PCB mounting with plated through-holes.","metaTitle":"1.5KE51C Littelfuse TVS Diode, 1500W, 43.6V Standoff","metaDescription":"Littelfuse 1.5KE51C bidirectional TVS diode, 1500W peak pulse power, 43.6V reverse standoff.
