At 4 A continuous output, that Rds(on) produces about 125 mW of conduction loss — well within the thermal budget of the 8-FC-TDFN (1.5x2) package when the exposed pad is soldered to a proper copper land on the PCB. For a factory-floor sensor node or a telecom line card running at 70°C internal ambient, this part has margin. ## Package, footprint, and reflow considerations The SLG59M309V comes in an 8-FC-TDFN (1.5x2) package, also called the 8-FC-TDFN (1.5x2) supplier package. It is offered in Tape & Reel (TR) and Cut Tape (CT) options. The reel format feeds directly into a pick-and-place line for volume production; the cut tape suits prototype builds and small-batch runs without committing to a full reel quantity. Surface-mount assembly is straightforward — the 1.5x2 mm footprint is small but not exotic, and the package coplanarity is standard for a TDFN. No special reflow profile beyond the solder paste manufacturer's recommendation for lead-free is needed. ## Active lifecycle and compliance For a BOM line that requires a high-side load switch with under 8 mOhm Rds(on) and a 4 A continuous rating, this part is a current-design fit — no last-time-buy planning or obsolescence risk to manage.","metaTitle":"Renesas SLG59M309V Load Switch, 7.8mOhm, 4A","metaDescription":"Renesas SLG59M309V high-side load switch: 7.8 mOhm Rds(on), 4 A output, 2.5-5.5 V supply, 8-FC-TDFN.

The only parametric difference is Rds(on): the SLG59M309V is 7.8 mOhm typical, while the SLG59M301V is 8.5 mOhm typical. For most 4 A loads, the 0.7 mOhm difference is negligible in terms of conduction loss, so the SLG59M309V drops into a board laid out for the SLG59M301V without a layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/SLG59M309V","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/SLG59M309V when reusing this data.
