The TO-220FP full-pack package isolates the tab electrically, so no insulating pad or washer is needed between the device and the heatsink. ## Gate charge and switching behaviour A gate driver sourcing 1 A can charge the gate in roughly 56 ns, though the practical switching speed is limited by the input capacitance of 2500 pF at Vds = 100 V and the gate-drive loop inductance. The MDmesh DM2 series includes a fast-recovery body diode, which reduces reverse-recovery losses in bridge topologies like LLC resonant converters or phase-shifted full bridges. ## Thermal and environmental ratings The TO-220FP package's junction-to-case thermal resistance is specified through the 40 W power dissipation limit at Tc = 25°C — derate above that case temperature per the datasheet curve.","metaTitle":"STF43N60DM2 MOSFET, N-Ch 600V 34A TO-220FP","metaDescription":"STMicroelectronics STF43N60DM2 N-channel 600V 34A MOSFET, 93mOhm Rds(on), TO-220FP full-pack, active production, ROHS3.

Both are 600 V N-channel MOSFETs in through-hole packages with similar gate charge (57 nC vs 56 nC) and on-resistance (88 mOhm vs 93 mOhm). The STFW40N60M2 has a slightly lower gate threshold (4 V max vs 5 V) and higher power dissipation (63 W vs 40 W). They are not pin-for-pin identical — the STFW40N60M2 uses a TO-247 package, which has a different footprint and tab size than the TO-220FP. A board spin is required to swap between them."},{"question":"What compliance documentation does STMicroelectronics provide for STF43N60DM2?","answer":"The part is ROHS3 compliant.
