If a transient pushes the line above approximately 133 V (the minimum breakdown), the device turns on and clamps. For a rail at 120 V nominal, this 10% headroom in breakdown is standard practice for Zener TVS selection. ## Temperature grade and thermal margin The 175 °C upper limit places this part above most commercial or even many industrial temperature grades; the upper rating matters in enclosed equipment where thermal soak is a real concern during fault conditions. The part is classified for general-purpose applications and is not flagged as power-line protection. If your board-level need is protecting a low-voltage rail from ESD or surge transients, the 5KP120A-HRA fills that role; it is not designed for dedicated mains-supply protection which typically requires a different form factor and holding current rating. ## Package and assembly form factor The P600 axial package is a standard through-hole lead form — the device mounts in a board hole and is wave or hand-soldered. Tape-and-reel packaging indicates it is delivered in production-reel quantities suitable for automated assembly.","metaTitle":"Littelfuse 5KP120A-HRA, 5kW Peak Pulse, Zener TVS Diode","metaDescription":"Littelfuse 5KP120A-HRA unidirectional Zener TVS diode, 120V standoff, 193V clamping, 5kW peak pulse, P600 axial.
