The clamping voltage maxes at 25.5 V at the full 60 A pulse — that is the voltage the protected circuit actually sees during the event. ## Package and board integration — DO-201 axial No power line protection is claimed — this is a signal-rail or low-voltage power-rail TVS, not a mains-side protector. The single bidirectional channel clamps both polarities, which is the usual choice for AC-coupled or bipolar signal lines.","metaTitle":"1.5KE18CAH TVS Diode, 1500W, 15.3V, DO-201, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE18CAH bidirectional TVS diode, 1500W peak pulse power, 15.3V standoff, 60A Ipp. AEC-Q101 qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Grade":"Automotive","Series":"1.5KE","Package":"Tape & Reel (TR)","Applications":"-","Mounting Type":"Through Hole","Qualification":"AEC-Q101","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE18","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"17.1V","Voltage - Clamping (Max) @ Ipp":"25.5V","Voltage - Reverse Standoff (Typ)":"15.3V","Current - Peak Pulse (10/1000µs)":"60A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5369","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/72a4f0b7488be17a5a1904958e6bdb59.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE18CAH/alternatives.json"},"ai":{"faq":[{"question":"What automotive qualification does the 1.5KE18CAH carry?","answer":"The part is AEC-Q101 qualified, which certifies it for automotive-grade stress testing: high-temperature reverse bias, temperature cycling, and ESD robustness per the AEC-Q101 discrete semiconductor qualification standard.
