Working backward from the reverse standoff of 11 V typical, the protection window between normal operation and first clip is roughly 7 V of headroom before the breakdown threshold of 12.2 V minimum kicks in. The single unidirectional channel means this part clamps positive transients only — it is not an AC mains protection device (confirms no power-line protection designation). The typical deployment is a secondary protection element on a supply rail, signal line, or data port that sees occasional IEC 61000-4-2 or similar ESD/surge stress. ## High-temperature grade and packaging The -55°C to 175°C operating range is wider than most TVS diodes in this power class — the 175°C die rating allows the part to sit close to a thermal source or in an enclosed panel without the typical 150°C ceiling limiting the placement. The P600 axial package with its copper alloy lead frame carries that heat away through the leads into the PCB copper. Packaged Tape & Reel on a through-hole axial part — this is not the default format for P600 devices (which more commonly ship loose or in Ammo Pack), so confirm your assembly line can handle tape-fed axial insertion before committing a high BOM quantity. ## Active production and sourcing Littelfuse marks the 5KP11A-HRA Active — no official successor or cross-reference appears in the published lifecycle record. The base product number 5KP1 anchors the family, but a parametric or package change is the buyer's responsibility to confirm if a substitute is needed.","metaTitle":"Littelfuse 5KP11A-HRA TVS Diode, 5kW Peak, 18.2V Clamp","metaDescription":"Littelfuse 5KP11A-HRA unidirectional TVS Zener, 5 kW peak pulse, 18.2 V clamping, 11 V standoff.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"5KP-HRA","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"P600, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"5000W (5kW)","Base Product Number":"5KP1","Operating Temperature":"-55°C ~ 175°C (TA)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"P600","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"12.2V","Voltage - Clamping (Max) @ Ipp":"18.2V","Voltage - Reverse Standoff (Typ)":"11V","Current - Peak Pulse (10/1000µs)":"280.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.7530","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b2de7fb7a7c7e32003c76b75bf060731.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I source 5KP11A-HRA and get a current quote?","answer":"Sourcing reach covers multiple independent channels with full traceability."},{"question":"What series does the 5KP11A-HRA belong to?","answer":"The part is in the Littelfuse 5KP-HRA series, a family of high-peak-pulse-power unidirectional TVS Zeners in the P600 axial package rated from 5000 W peak pulse upward.
