The bidirectional channel handles both positive and negative polarity surges, making it suitable for AC power rails or bipolar signal lines. ## Package and thermal envelope Housed in a DO-201AE axial-lead package, the 1.5KE220CA_R2_00001 mounts through hole — the leaded body provides a low-inductance path for fast transients and allows manual or wave-solder assembly. The junction temperature range spans -65 °C to 175 °C, covering industrial and some military-grade thermal profiles without derating at the high end. No power line protection feature is built in — this is a dedicated transient suppressor, not a crowbar or overvoltage clamp for continuous faults. ## Obsolete — sourcing through independent channels No official successor order code is recorded from Panjit. The 1.5KE series includes other bidirectional TVS devices at different voltage ratings, but a direct pin-compatible replacement at the same 185 V standoff is not documented. Buyers should verify the clamping voltage and peak pulse current requirements before selecting an alternative.","metaTitle":"Panjit 1.5KE220CA_R2_00001 TVS, 1500W, 185V Standoff","metaDescription":"Obsolete Panjit 1.5KE220CA_R2_00001 bidirectional TVS diode, 1500W peak pulse, 185V standoff, 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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201AE","Voltage - Breakdown (Min)":"209V","Voltage - Clamping (Max) @ Ipp":"328V","Voltage - Reverse Standoff (Typ)":"185V","Current - Peak Pulse (10/1000µs)":"4.6A"}},"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can I buy the 1.5KE220CA_R2_00001?","answer":"The 1.5KE220CA_R2_00001 is obsolete but available through independent distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5KE220CA_R2_00001","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/panjit-international-inc/1.5KE220CA_R2_00001 when reusing this data.
