Because it is a standard DO-201AE TVS, parametric equivalents from other manufacturers may be considered for new designs, but no direct cross-reference is held on this record. ## Voltage Ratings and Clamping Performance The 17.1 V reverse standoff voltage means this diode starts conducting only when the line exceeds that level — it sits across a 12 V or 15 V rail without leaking appreciably under normal operation. The 19 V minimum breakdown guarantees the avalanche region is entered before the voltage reaches a level that would stress downstream silicon rated at, say, 20 V absolute maximum. ## Package and Mounting — DO-201AE Axial The DO-201AE axial package requires a through-hole PCB footprint with lead spacing matching the body length — typically 0.375-inch lead spacing on 0.050-inch diameter holes. The -65°C to 175°C operating junction range covers extreme environments from cold storage to engine-bay heat, but the junction temperature during a transient event rises above ambient — the 175°C limit must include the adiabatic temperature rise from the pulse.","metaTitle":"Panjit 1.5KE20A_R2_00001 TVS Diode, 1500W, 27.7V Clamp","metaDescription":"Obsolete Panjit 1.5KE20A_R2_00001 unidirectional TVS, 1500W peak pulse power, 27.7V clamp, DO-201AE.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Panjit International Inc.","Type":"Zener","Series":"1.5KE","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AE, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-65°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201AE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"19V","Voltage - Clamping (Max) @ Ipp":"27.7V","Voltage - Reverse Standoff (Typ)":"17.1V","Current - Peak Pulse (10/1000µs)":"54A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/adbd088802f505fd96ec586b80ab0f5a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Who supplies 1.5KE20A_R2_00001 and how is it quoted for volume purchases?","answer":"This part is supplied through independent distribution.
