An OEM auditor reviewing the BOM line for a 324 V nominal bus transient suppressor sees the AEC-Q101 certificate as the hard stop — no industrial-grade 'automotive-capable' substitute clears that gate. ## 1500W surge window — breakdown, clamp, and standoff The reverse standoff voltage of 324 V means the TVS remains transparent below that bus level — leakage stays within datasheet limits — while the minimum breakdown of 360 V ensures the avalanche trigger is well above the nominal rail. The 574 V clamp must sit below the downstream load's absolute maximum rating; a 600 V-rated MOSFET or IGBT has only 26 V of margin at the clamp ceiling, so the surge energy must be verified against the load's avalanche capability.","metaTitle":"TSC 1.5KE400H 1500W Zener TVS, AEC-Q101, 324V Standoff","metaDescription":"1.5KE400H Taiwan Semiconductor 1.5kW peak pulse Zener TVS, AEC-Q101 qualified, 324V reverse standoff, 574V clamp, -55 to +175°C.","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":"General Purpose","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":"1.5KE400","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"360V","Voltage - Clamping (Max) @ Ipp":"574V","Voltage - Reverse Standoff (Typ)":"324V","Current - Peak Pulse (10/1000µs)":"2.7A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3617","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9872061a41a0e5d6da92467b55d2aea3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the 1.5KE400H's AEC qualification grade?","answer":"The 1.5KE400H is AEC-Q101 qualified, which is the automotive discrete semiconductor stress qualification.
