The 12.8V standoff leaves margin on a 12V battery line that can sag to 9V during cold crank and still not clip the signal; the 21.2V clamp catches load-dump spikes before they reach the transceiver's abs-max rating.","metaTitle":"1.5KE15CAHA0G TVS Diode, 1500W, 12.8V Standoff, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE15CAHA0G bidirectional Zener TVS, 1500W peak pulse, 12.8V standoff, 21.2V clamping, DO-201, AEC-Q101 automotive grade.","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 & Box (TB)","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":"1.5KE15","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"14.3V","Voltage - Clamping (Max) @ Ipp":"21.2V","Voltage - Reverse Standoff (Typ)":"12.8V","Current - Peak Pulse (10/1000µs)":"74A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5369","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a688563676897fea683fa9d5a5542f4e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation does Taiwan Semiconductor provide for 1.5KE15CAHA0G?","answer":"The part carries AEC-Q101 automotive qualification, which includes the full suite of reliability stress tests (HTRB, H3TRB, temperature cycling, ESD) and PPAP documentation.
