Junction temperature range spans -55°C to 175°C, so the clamping performance holds across cold-crank and under-hood thermal profiles without derating the peak pulse power at elevated ambient. ## AEC-Q101 qualification and 3.2A pulse current The 1500W rating is tested at 25°C; derate linearly above that per the datasheet curve. Peak pulse current is 3.2A for the 10/1000µs waveform at the 482V clamp voltage. For shorter transients (8/20µs), the peak current capability is significantly higher — the 1500W rating is energy-limited, not current-limited. No power line protection feature — this is a transient suppressor, not a continuous overvoltage clamp. It is designed for occasional surge events, not sustained fault conditions. The 1.5KE series is a mature standard-product line with broad cross-shipment across multiple manufacturers, so allocation risk is low outside a general passive/component shortage cycle. The DO-201AA / DO-27 / Axial package is a standard JEDEC outline; no custom tooling required. Sourced through independent distribution channels with full lot traceability.","metaTitle":"1.5KE350CAH TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE350CAH bidirectional Zener TVS, 300V standoff, 482V clamp, 1500W peak pulse, 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 & 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":"1.5KE350","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"333V","Voltage - Clamping (Max) @ Ipp":"482V","Voltage - Reverse Standoff (Typ)":"300V","Current - Peak Pulse (10/1000µs)":"3.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3688","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a40d12b3fcc4c0fd8870b04aa775c30a.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5KE350CAH","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/taiwan-semiconductor-corporation/1.5KE350CAH when reusing this data.
