AEC-Q101 qualification certifies the part for automotive stress levels — temperature cycling, high-temperature reverse bias, and ESD robustness per the automotive discrete semiconductor standard. The 3.2A peak pulse current at the clamping voltage is carried through the lead frame; board layout should keep the trace width from the anode to the protected rail at least as wide as the lead diameter to avoid a secondary fuse effect. ## Sourcing and lifecycle posture No official second-source cross-reference is published, but the 1.5KE series footprint is shared by multiple TVS diode manufacturers for alternative sourcing evaluation.","metaTitle":"1.5KE350AHA0G TVS Diode, 1500W, 300V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE350AHA0G Zener TVS diode, 1500W peak pulse, 300V standoff, 482V clamp, AEC-Q101 automotive grade, DO-201 axial.","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":"1.5KE350","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","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":"$0.3617","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a688563676897fea683fa9d5a5542f4e.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5KE350AHA0G","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/1.5KE350AHA0G when reusing this data.
