The 256.3 A peak pulse current rating tells you it survives a direct-strike surge event without going short, which matters for telecom cabinets and outdoor equipment that see unshielded cable runs. ## The three-voltage spec chain — standoff, breakdown, clamping Reverse standoff of 12 V is the working voltage the part idles at without conducting. Below 13.3 V it draws only leakage; once a surge raises the rail above breakdown it avalanche-comments and clamps at 19.9 V maximum — that 1.66× ratio between standoff and clamping is the suppressor's let-through budget for whatever is behind it.","metaTitle":"YAGEO 5KP12A/B Zener TVS Diode, 12V standoff, 5kW peak","metaDescription":"YAGEO 5KP12A/B unidirectional Zener TVS diode, 12V standoff, 13.3V min breakdown, 19.9V clamping, 5kW peak pulse, P600 axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"YAGEO","Type":"Zener","Series":"5KP","Package":"Box","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"P600, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"5000W (5kW)","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"P600","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"13.3V","Voltage - Clamping (Max) @ Ipp":"19.9V","Voltage - Reverse Standoff (Typ)":"12V","Current - Peak Pulse (10/1000µs)":"256.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a35eae7bc672199f45cbb981d91ccbe1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What does 5KP stand for in the 5KP12A/B part number?","answer":"The 5KP series is YAGEO's 5000 W peak-pulse rating class.
