No official successor order code is recorded from the manufacturer. For new designs or volume production, a functionally equivalent TVS diode in the same 1500W, 12V-class family should be evaluated. The AEC-Q101 qualification and DO-201AA footprint are the primary fit constraints. ## Clamping performance and application fit The 1500W peak pulse rating at 10/1000µs means it absorbs high-energy surges without failing short — the TransZorb® silicon-avalanche construction handles repetitive events within the junction temperature envelope. Power line protection is not supported (no bidirectional or crowbar function) — this is a single-direction clamp for unipolar rails. The axial-lead DO-201AA body suits point-to-point wiring on terminal blocks or PCB through-hole layouts where surface-mount reflow is not an option.","metaTitle":"1.5KE15HE3/54 TVS Diode, 1500W, 12.1V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE15HE3/54 Zener TVS diode, 1500W peak pulse, 12.1V reverse standoff, AEC-Q101 qualified.","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":"Automotive, AEC-Q101, TransZorb®","Package":"Tape & Reel (TR)","Applications":"Automotive","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":"1.5KE15","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"13.5V","Voltage - Clamping (Max) @ Ipp":"22V","Voltage - Reverse Standoff (Typ)":"12.1V","Current - Peak Pulse (10/1000µs)":"68.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 1.5KE15HE3/54?","answer":"No official pin-compatible successor is recorded from Vishay.
