The DO-201AE axial-lead package is a through-hole form factor that suits point-to-point wiring or PCB mounting where the board can handle the lead diameter. Operating temperature spans -65°C to 175°C junction, covering most industrial and telecom environments. ## Obsolete — what that means for a BOM line Panjit lists this part as obsolete. No official successor order code is recorded, so the BOM line relies on independent-distribution inventory — surplus, overstock, or last-time-buy lots that are traceable and tested. For a 24 V rail TVS, the closest functional equivalent would share the same standoff voltage (20.5 V), clamp voltage (~33 V), and 1500 W peak pulse rating in a DO-201AE package. Without a factory-specified cross, the replacement is parametric — confirm the clamp voltage and pulse current match the protection requirement before substituting. ## Voltage ratings and pulse current — the selection check The breakdown voltage min is 22.8 V, so the diode starts conducting just above the 20.5 V standoff. Power line protection is marked 'No' — this is a unidirectional Zener TVS for DC rails, not an AC power-line suppressor. The single unidirectional channel handles positive transients referenced to ground; a bidirectional pair would be needed for AC-coupled lines.","metaTitle":"Panjit 1.5KE24A_R2_00001 TVS Diode, 1500W, DO-201AE","metaDescription":"Panjit 1.5KE24A_R2_00001 Zener TVS, 1500W peak pulse, 20.5V standoff, 33.2V 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)":"22.8V","Voltage - Clamping (Max) @ Ipp":"33.2V","Voltage - Reverse Standoff (Typ)":"20.5V","Current - Peak Pulse (10/1000µs)":"45A"}},"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 is the closest pin-compatible alternative to 1.5KE24A_R2_00001?","answer":"No official successor is recorded.
