STF25NM60ND Descripción general
The STMicroelectronics STF25NM60ND is an N-channel 600 V power MOSFET built on the FDmesh II trench technology, rated for 21 A drain current (at Tc) and 40 W power dissipation in an isolated TO-220FP package. Its typical on-resistance of 0.13 ohm and integrated fast-recovery body diode make it well suited for off-line switched-mode power conversion.
A power MOSFET is a voltage-controlled semiconductor switch used to regulate or convert electrical power. Within the component hierarchy, the STF25NM60ND belongs to the transistor family, specifically the MOSFET (metal-oxide-semiconductor field-effect transistor) class, which sits within the broader category of discrete semiconductors and power management components. Power MOSFETs are the switching elements in SMPS topologies such as flyback, forward, half-bridge and resonant converters.
Key features include the 600 V drain-source breakdown voltage rating for universal-mains rectified-bus applications, FDmesh II process technology that lowers RDS(on) and gate charge for improved efficiency, and the fast-recovery intrinsic body diode (indicated by the D suffix) that reduces reverse-recovery losses in hard-switched topologies such as two-switch forward and LLC converters. The F suffix in the part number denotes the TO-220FP fully molded isolated package, providing 2500 Vrms electrical isolation without an external insulator, simplifying heatsink mounting.
The FDmesh II stripe-trench architecture balances conduction and switching losses, allowing designers to optimize for either low-frequency conduction efficiency or high-frequency switching performance. Low gate charge reduces gate-drive losses, while the rugged body diode withstands avalanche events typical of transformer-leakage-inductance environments.
Typical applications include off-line flyback and forward AC-DC converters for industrial power supplies, PFC pre-regulator stages, motor drive inverter legs for light industrial loads, and high-voltage DC-DC modules for solar and telecom rectifiers.
Design tip: the TO-220FP isolated package has higher thermal resistance than standard TO-220, so verify junction temperature with proper heatsink sizing; drive the gate with a low-impedance driver (e.g., 10 ohm series resistor) to manage EMI from fast switching edges.

Guía de selección
Choose the STF25NM60ND when you need a 600 V, 21 A N-channel MOSFET with an isolated TO-220FP package for off-line power converters requiring a fast-recovery body diode and no external isolation pad. Choose STP25NM60ND for non-isolated TO-220 mounting with better thermal performance. Choose STB25NM60ND (D2PAK) for surface-mount-friendly boards. Choose STF23NM60ND when slightly lower current (23 A class) suffices at lower cost. For 650 V designs with more margin, consider STF24NM65N. The isolated FP package trades thermal resistance for mounting convenience and isolation.
