STMicroelectronics STP6N60M2

Overview

STP6N60M2 from STMicroelectronics is an N-channel 600 V, 1.06 Ω typ. (1.2 Ω max.), 4.5 A MDmesh M2 Power MOSFET in TO-220 package, optimized for high-efficiency flyback and PFC converters with low gate charge (8 nC) and rugged 50 V/ns dv/dt capability.

For engineers reviewing the STP6N60M2 datasheet, STP6N60M2 pinout, STP6N60M2 application, or STP6N60M2 equivalent, this device is selected for high-voltage AC/DC power supplies where low conduction loss, fast switching, avalanche robustness, and Zener-protected gate integrity are critical design requirements.

Technical Context

This MOSFET employs ST's MDmesh M2 strip layout and enhanced vertical structure to achieve low R_DS(on) while maintaining excellent C_oss profile (14 pF typ.) and low Q_gd (4 nC), enabling high-frequency operation with reduced switching losses.

It features 100% unclamped inductive switching (UIS) tested to 86 mJ at 25 °C, ±25 V gate rating, and integrated Zener protection-critical for reliable gate drive in noisy industrial and adapter environments.

Key Specifications

Pinout & Package

TO-220 package (Type A): insulated case, 3-pin through-hole mounting with tab-drain configuration. Thermal resistance R_thJC = 2.08 °C/W enables 60 W dissipation at T_C = 25 °C.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage power switching applications.

Compared with STF6N60M2 and FDPF18N50, STP6N60M2 uniquely balances 600 V rating, Zener-protected gate, and 86 mJ avalanche energy-making it the only option among the three qualified for universal-input, unclamped-inductive, and thermally constrained industrial power supplies.

FAQ

Is STP6N60M2 pin-compatible with STF6N60M2?

No. STP6N60M2 uses TO-220 (tab-drain, non-insulated), while STF6N60M2 uses TO-220FP (fully insulated tab). Pin numbering is identical (G-D-S), but mechanical mounting, thermal interface, and creepage requirements differ significantly-direct substitution requires PCB and heatsink redesign.

What is the maximum recommended gate resistor value for 100 kHz operation?

For 100 kHz switching with 8 nC Q_g, a 10 Ω gate resistor limits peak gate current to <1 A and keeps turn-on time below 80 ns. Values above 22 Ω risk excessive switching loss; values below 4.7 Ω require careful layout to avoid ringing due to L_g interaction with Q_gd.

Does STP6N60M2 include body diode recovery optimization?

Yes. Its source-drain diode has t_rr = 274 ns (T_J = 25 °C) and Q_rr = 1.47 µC, optimized via controlled carrier lifetime. This reduces diode-induced switching loss and EMI in discontinuous conduction mode (DCM) flyback topologies.

Can STP6N60M2 be used in synchronous rectification?

No. It is an N-channel high-side switch with drain-connected tab and no integrated Schottky or low-V_SD enhancement. Synchronous rectification requires low forward-voltage, bidirectional conduction, and often P-channel or dedicated SR controller pairing-none supported by this part's topology or characterization.
