Switching frequency is fixed to the line frequency (50 Hz to 60 Hz), so the part synchronises directly with the AC mains zero-crossing — no external oscillator or timing capacitor is needed, and the switching losses are low because the device toggles only 100 or 120 times per second. Current-limiting fault protection is built in — if the output current exceeds the threshold, the internal switch latches off or cycles, protecting the load and the IC itself without an external sense resistor. ## Package, temperature range, and shelf-life considerations Store the reels dry — the SOIC package is typically MSL 1 or 2, but verify the moisture sensitivity level on the reel label before baking.","metaTitle":"SR10LG-G Microchip Technology Offline Switch, Shunt Topology","metaDescription":"SR10LG-G offline switch IC from Microchip Technology, shunt topology, 50-60 Hz switching, current limiting, 8-SOIC, ROHS3 compliant, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Shunt","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting","Output Isolation":"Non-Isolated","Internal Switch(s)":"Yes","Frequency - Switching":"50Hz ~ 60Hz","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"8-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.69","priceTiers":[{"qty":1,"price":"$0.69000","currency":"USD"},{"qty":25,"price":"$0.58320","currency":"USD"},{"qty":100,"price":"$0.53000","currency":"USD"},{"qty":3300,"price":"$0.53000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4b70d84c1afac35b79198e2e9e6366a8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SR10LG-G/alternatives.json"},"ai":{"faq":[{"question":"Is SR10LG-G available via RFQ confirmation and what is the lead time for an order?","answer":"Submit an RFQ for the SR10LG-G and we will provide the lead time and quantity options from our distribution channels."},{"question":"What is SR10LG-G's listed topology?","answer":"The SR10LG-G uses a shunt topology — the internal switch shunts the output to ground during the off-cycle, regulating the output by dissipating excess energy rather than storing it in a transformer."},{"question":"What compliance documentation does Microchip Technology provide for SR10LG-G?","answer":"The SR10LG-G is ROHS3 compliant (no exemptions)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SR10LG-G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SR10LG-G when reusing this data.
