The 33.3 V reverse standoff voltage means the diode stays out of the circuit below that level; it only starts conducting when the line exceeds the 37.1 V minimum breakdown threshold. ## Package and board-fit for a through-hole design Housed in a DO-201AE axial-lead package, this TVS diode is a through-hole part — it inserts into a plated through-hole on the PCB and is wave-soldered or hand-soldered. Operating temperature spans -65 °C to 175 °C junction, covering military and industrial thermal extremes — a relay driver or motor controller in a hot cabinet sees no derating concern. ## Lifecycle status and how to source it now Panjit lists the 1.5KE39A_R2_00001 as obsolete — the manufacturer no longer produces it as a standard catalogue item. No official successor order code is recorded from Panjit; the closest functional replacement is another 1.5KE39A from a different brand or a current-production TVS with the same 33.3 V standoff and DO-201AE package, but pin-compatibility must be verified per the BOM position. We source this part through independent distribution channels — surplus and new-old-stock inventory.","metaTitle":"Panjit 1.5KE39A_R2_00001 TVS Diode, 1.5kW, 53.9V Clamp","metaDescription":"Panjit 1.5KE39A_R2_00001 Zener TVS diode, 1500W peak pulse, 53.9V clamp, 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","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201AE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"37.1V","Voltage - Clamping (Max) @ Ipp":"53.9V","Voltage - Reverse Standoff (Typ)":"33.3V","Current - Peak Pulse (10/1000µs)":"28A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/adbd088802f505fd96ec586b80ab0f5a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 1.5KE39A_R2_00001 and get a price?","answer":"We source this obsolete TVS diode through independent distribution — surplus and new-old-stock inventory.
