Mosorb™ series, Type Zener, 1.5KE13ARL4G, 1500W peak pulse power, 11.1V reverse standoff, 18.2V clamping, 82A peak pulse current, DO-201AD axial, through-hole.","salesMarkdown":"## Surge protection for a DC rail The 1.5KE13ARL4G: When the voltage exceeds the breakdown threshold, the device shunts the surge to ground, clamping at 18.2V maximum while passing up to 82A of peak pulse current (10/1000µs waveform). ## What the ratings mean for the circuit The 18.2V clamping voltage at 82A peak pulse current means a 1500W surge (18.2V × 82A) is clamped to a level that protects downstream components rated for at least 20V, typical for 12V-rated silicon. Operating temperature from -65°C to 175°C covers military and industrial extremes — the junction can handle the self-heating from repetitive surges without derating until the ambient approaches 175°C. ## Field-swap reality The DO-201AD axial package is a through-hole part with two leads — orientation is obvious (the cathode band marks the striped end), and it swaps with basic soldering iron and desoldering wick on site without a hot-air station. Tape and Reel packaging means the part ships on a reel for automated insertion, but a single unit can be cut from the tape and hand-soldered — no special handling required beyond standard ESD precautions.","metaTitle":"1.5KE13ARL4G Littelfuse Mosorb TVS, 1500W, DO-201AD","metaDescription":"Littelfuse 1.5KE13ARL4G Mosorb Zener TVS diode, 1500W peak pulse, 11.1V standoff, 18.2V clamp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"Mosorb™","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AD, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","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)":"12.4V","Voltage - Clamping (Max) @ Ipp":"18.2V","Voltage - Reverse Standoff (Typ)":"11.1V","Current - Peak Pulse (10/1000µs)":"82A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b2bad05ac2a782d44789dbfb00c46ecc.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5KE13ARL4G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5KE13ARL4G when reusing this data.
