The bidirectional configuration means a single device protects both positive and negative transients, simplifying BOM count on unipolar and bipolar rails alike. ## Clamping performance and thermal envelope With a 207 V clamping ceiling at 7.2 A, this TVS absorbs surges that would otherwise exceed the breakdown rating of downstream semiconductors on a 128 V nominal rail. The 1500 W peak pulse rating assumes the standard 10/1000 µs double-exponential waveform — derate for shorter pulse widths or higher ambient temperatures per the manufacturer's pulse derating curve. Operating junction temperature spans -65°C to 175°C, covering cold-start conditions in outdoor telecom cabinets and the hot interior of sealed power supplies. The DO-201AE axial-lead package (through-hole) conducts heat through the lead wires into the PCB copper or terminal block — the thermal path is set by the lead length and pad area, not the body alone. ## Obsolete — sourcing through independent channels Panjit lists the 1.5KE150CA_R2_00001 as obsolete — the manufacturer no longer produces it. Available through independent surplus and broker channels. Quantities are lot-specific; each lot is inspected for authenticity and lead-free compliance before shipment.","metaTitle":"Panjit 1.5KE150CA_R2_00001 TVS Diode, 1500W, 128V Standoff","metaDescription":"Panjit 1.5KE150CA_R2_00001 bidirectional Zener TVS diode, 1500W peak pulse power, 128V reverse standoff, DO-201AE axial.","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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201AE","Voltage - Breakdown (Min)":"143V","Voltage - Clamping (Max) @ Ipp":"207V","Voltage - Reverse Standoff (Typ)":"128V","Current - Peak Pulse (10/1000µs)":"7.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/adbd088802f505fd96ec586b80ab0f5a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does the 1.5KE150CA_R2_00001 come in?","answer":"It is supplied in the DO-201AE axial-lead package (through-hole).
