If a board spin is acceptable, a functionally equivalent 1500 W bidirectional TVS in the same DO-201AA footprint from another manufacturer may serve as a drop-in — confirm the clamping voltage and breakdown window against the original design. ## 1500 W peak pulse — what the rating means The 3.1 A peak pulse current at the clamping voltage tells you the diode can absorb a substantial transient without failing short. Above that, breakdown starts at 333 V minimum, and the clamping voltage caps at 482 V — the protected circuit sees no more than 482 V across the transient. ## Through-hole DO-201AA axial package The wide range means derating for ambient temperature is minimal until you approach the upper limit.","metaTitle":"1.5KE350CA-E3/54 TVS Diode, 1500W, 300V, DO-201AA","metaDescription":"Vishay 1.5KE350CA-E3/54 TransZorb bidirectional TVS, 1500W peak pulse, 300V standoff, DO-201AA axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"TransZorb®","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","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":"1.5KE","Voltage - Breakdown (Min)":"333V","Voltage - Clamping (Max) @ Ipp":"482V","Voltage - Reverse Standoff (Typ)":"300V","Current - Peak Pulse (10/1000µs)":"3.1A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does the 1.5KE350CA-/54 come in?","answer":"It is a through-hole axial-lead package, specifically DO-201AA (also known as DO-27).
