The fully isolated TO-220 Full Pack package (TO-220FP) allows direct heatsink mounting without an insulating pad, which simplifies assembly and improves thermal transfer in high-voltage offline designs such as power-factor-correction stages, LLC resonant converters, and two-switch forward topologies. At 21 A, the dissipation from on-resistance alone is about 28 W, which the TO-220FP's 40 W power-dissipation ceiling must accommodate with adequate heatsinking. A driver capable of sourcing and sinking several amperes peak is recommended to keep switching transitions crisp and avoid excessive cross-conduction in bridge topologies.","metaTitle":"STF57N65M5 N-Channel 650 V 42 A MOSFET, MDmesh V, TO-220FP","metaDescription":"STF57N65M5 N-channel 650 V 42 A MOSFET, 63 mΩ Rds(on), MDmesh V series, TO-220FP isolated package.

Higher frequencies require a gate driver with sufficient peak current to charge the gate capacitance quickly and avoid excessive switching losses."},{"question":"How does STF57N65M5 compare to STF55N65M5?","answer":"The STF55N65M5 is a lower-current variant in the same MDmesh V family, typically rated for lower continuous drain current. The STF57N65M5 offers higher current capability (42 A) and the same 650 V drain-source rating. Pin-compatible in the same TO-220FP package, but the on-resistance and gate charge differ — check the respective datasheets for exact parametric differences before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STF57N65M5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STF57N65M5 when reusing this data.
