It clamps at 30.6V max with a 49A peak pulse current rating, making it suitable for protecting 18.8V nominal rails in general-purpose power supplies and industrial control circuits. ## Voltage thresholds and surge capability The reverse standoff voltage is 18.8V typ, meaning the device does not conduct appreciably below that rail voltage. Breakdown occurs at 20.9V min, and the clamping voltage is held to 30.6V max at the rated 49A peak pulse current — a tight clamp for a 1500W device that keeps downstream silicon within its safe operating area during a surge event. ## Obsolete status and sourcing reality onsemi lists the 1.5KE22AG as Obsolete. Sourcing is per RFQ; we can locate inventory across our distributor network and quote against your line-item quantity. The DO-201AD axial package is through-hole mounted — the lead bend and body length are standard for axial-lead TVS diodes, so it fits existing PCB layouts designed for the 1.5KE series footprint.","metaTitle":"1.5KE22AG Zener TVS Diode – onsemi Mosorb™ 1500W DO-201AD","metaDescription":"1.5KE22AG Zener TVS from onsemi Mosorb™ series. 1500W peak pulse, 18.8V standoff, 30.6V clamp, 49A Ipp. Obsolete – source here per RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"onsemi","Type":"Zener","Series":"Mosorb™","Package":"Bulk","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AD, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-65°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"20.9V","Voltage - Clamping (Max) @ Ipp":"30.6V","Voltage - Reverse Standoff (Typ)":"18.8V","Current - Peak Pulse (10/1000µs)":"49A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/717ad1fc0ab391931f54c66e75e89e87.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE22AG/alternatives.json"},"ai":{"faq":[{"question":"How can I order 1.5KE22AG or get a quote?","answer":"The 1.5KE22AG is obsolete per onsemi, but we can source it through our distributor network.

A common cross-reference is the 1.5KE22A (without the 'G' suffix) — verify the 'G' indicates lead-free / RoHS compliance, and check the clamping and breakdown voltages match your protection threshold."},{"question":"Can I replace 1.5KE22AG with 1.5KE22A?","answer":"The 1.5KE22A is electrically identical in breakdown, clamping, and peak pulse ratings. The 'G' suffix on the 1.5KE22AG typically denotes lead-free / RoHS compliance. If your BOM requires RoHS, confirm the 1.5KE22A variant you source meets that standard."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/1.5KE22AG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/1.5KE22AG when reusing this data.
