Product details

500 V N-channel MOSFET in DPAK — MDmesh DM2 series

The STD12N50DM2 is housed in a surface-mount DPAK (TO-252) package, suitable for automated assembly in high-density power supplies, offline flyback converters, PFC stages, and motor-drive auxiliary supplies.

Switching and conduction loss budget

The 350 mΩ Rds(on) at 10 V gate drive is the conduction loss anchor: at 5.5 A the dissipation is about 10.6 W, which must be removed through the DPAK's thermal pad. The input capacitance of 628 pF at 100 V Vds keeps the Miller plateau short, aiding fast turn-on and turn-off transitions.

The gate-source voltage is rated ±25 V, giving margin against ringing in hard-switched topologies.
