The 95 mOhm Rds(on) at 10 V gate drive gives a low conduction-loss floor at 15 A load current, while the 71 nC total gate charge keeps the switching energy per cycle manageable in the 50–150 kHz range typical of LLC resonant converters and PFC stages. ## TO-220FP — isolated tab, higher thermal resistance That simplifies assembly and cuts a BOM line, but the plastic encapsulation adds thermal resistance: the 35 W power dissipation ceiling at case temperature is lower than a standard TO-220 would deliver. The junction-to-case thermal path is the constraint; a 150°C maximum junction temperature means the heatsink must keep the case temperature low enough to stay within the 35 W budget at the actual load current. The part is ROHS3 compliant.","metaTitle":"STF38N65M5 MOSFET, N-Ch 650V 30A TO-220FP, 95mOhm","metaDescription":"STF38N65M5 N-channel 650V 30A MOSFET in TO-220 Full Pack. 95mOhm Rds(on) at 10V gate drive, 71nC gate charge.

The M5 typically offers lower Rds(on) and reduced gate charge for the same voltage and current class, which translates to lower conduction and switching losses in a power supply design. Pin-compatible in the same TO-220FP footprint, so a BOM swap is straightforward if the M2 is the incumbent."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STF38N65M5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STF38N65M5 when reusing this data.
