A downstream circuit expecting to see larger surge currents needs a higher-rated TVS or a coordinated upstream gas-discharge tube. The 5 kW rating is the product of the 300 A and the 17 V clamping voltage, so both numbers must be evaluated together against the threat profile of the end equipment. Bidirectional means it clamps both polarities without a stacking diode arrangement — the 'CA' suffix confirms the bidirectional polarity orientation. The 10 V reverse standoff is the bias level the TVS sits above during normal operation; the 11.1 V minimum breakdown is where it begins conducting, and the 17 V maximum clamping voltage is what the protected node is exposed to during the active event. ## Voltage thresholds and what they protect The 10 V standoff rating makes this part suited for 5 V and 12 V rail protection — it sits off-state above the normal operating voltage. For a 12 V automotive or industrial rail, a 10 V standoff gives roughly 2 V of margin above the nominal rail, which is typical for transient protection on those bus voltages. A 5 V rail with this part has tighter margin, which may be acceptable for EFT and ESD events but not for load-dump transients without additional headroom. Layout should keep the TVS leads short and the thermal path to the board plane clear; the P600 axial leadframe dissipates some heat through the leads before it reaches the epoxy body.","metaTitle":"YAGEO 5KP10CA/B TVS Diode, 5kW 300A P600 Axial","metaDescription":"YAGEO 5KP10CA/B bidirectional TVS diode, 5kW peak pulse, 17V clamping, 300A surge capacity, P600 axial, Active production.","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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"P600","Voltage - Breakdown (Min)":"11.1V","Voltage - Clamping (Max) @ Ipp":"17V","Voltage - Reverse Standoff (Typ)":"10V","Current - Peak Pulse (10/1000µs)":"300A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8366","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a35eae7bc672199f45cbb981d91ccbe1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What voltage does the 5KP10CA/B actually clamp at during a surge?","answer":"The maximum clamping voltage is 17 V at the rated peak pulse current of 300 A (10/1000 µs). The device transitions from its off-state at 10 V standoff, begins conducting at the 11.1 V minimum breakdown, and limits the surge voltage to 17 V at the peak current — that 17 V ceiling is what the downstream circuit sees during the event."},{"question":"What does 'CA' in the 5KP10CA/B suffix mean, and what is the difference from a 5KP10A?","answer":"The 'CA' denotes a bidirectional polarity configuration — it clamps both positive and negative transients without requiring a stacked diode arrangement. A plain 'A' suffix (5KP10A) is unidirectional.
