When the transient hits, the diode clamps at 482V maximum, shunting up to 3.2A of peak pulse current away from the downstream circuitry. That clamp voltage is the ceiling the protected device sees — a 300V-rated MOSFET with a 500V drain-source breakdown has margin here. The DO-201AA (DO-27) axial package is through-hole — the leads absorb thermal shock during soldering and the body can be reworked with standard hot-air or iron methods. No moisture sensitivity level to track; it ships in Tape & Box. ## Active production — sourcing posture For a 300V bidirectional TVS in a DO-201 footprint, this is the direct order code.","metaTitle":"1.5KE350CAHA0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE350CAHA0G bidirectional TVS diode, 300V standoff, 482V clamp, 1500W peak pulse, AEC-Q101 qualified, 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","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/a688563676897fea683fa9d5a5542f4e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation does Taiwan Semiconductor Corporation provide for 1.5KE350CAHA0G?","answer":"The part carries AEC-Q101 automotive qualification.
