STMicroelectronics STB22N60DM6

Overview

STB22N60DM6 from STMicroelectronics is a high-voltage N-channel Power MOSFET in the MDmesh DM6 series, featuring 600 V V_DS, 240 mΩ max R_DS(on) at 10 V V_GS, and 15 A continuous drain current at T_C = 25 °C. It integrates a fast-recovery body diode with 88 ns trr (T_j = 25 °C) and 0.299 µC Q_rr, enabling high-efficiency ZVS phase-shift converters and bridge topologies.

For engineers reviewing the STB22N60DM6 datasheet, STB22N60DM6 pinout, STB22N60DM6 application, or STB22N60DM6 equivalent, key selection criteria include its 100 V/ns dv/dt ruggedness, 20.6 nC total gate charge, 1.6 V forward diode voltage at 15 A, 100% avalanche tested rating (320 mJ E_AS), and D²PAK thermal resistance of 0.96 °C/W.

Technical Context

This MOSFET employs ST's MDmesh DM6 silicon process, optimized for ultra-low Q_rr and trr while maintaining industry-leading R_DS(on)/area. Its Zener-protected gate structure ensures ±25 V V_GS tolerance and robust ESD immunity.

The device delivers 100 V/ns MOSFET dv/dt ruggedness and 100 V/ns diode recovery dv/dt capability under defined conditions (V_DD = 400 V, I_SD ≤ 15 A). Its C_oss,eq of 157 pF supports soft-switching performance in resonant topologies.

FAQ

What is the maximum recommended gate resistor value for reliable switching?

A 4.7 Ω gate resistor is specified in the datasheet test circuit for resistive load switching. For ZVS operation, values between 2.2 Ω and 10 Ω balance turn-on speed against ringing suppression; values above 15 Ω increase switching time and may compromise dv/dt immunity due to slower gate voltage slew rate.

Can STB22N60DM6 replace STP22N60DM6 in existing designs?

Yes, STB22N60DM6 is the D²PAK variant of the same MDmesh DM6 die used in STP22N60DM6 (TO-220FP). Electrical parameters are identical, but thermal performance differs: R_thJC is 0.96 °C/W vs 1.25 °C/W, and PCB layout must accommodate the D²PAK footprint and thermal pad requirements.

Is the body diode suitable for synchronous rectification?

No - the integrated body diode is optimized for fast recovery in freewheeling roles, not bidirectional conduction. Its 1.6 V forward voltage and 88 ns trr make it unsuitable for synchronous rectification, where discrete Schottky or GaN FETs with sub-0.5 V V_F are preferred.

What is the safe operating area (SOA) limitation at 100 °C case temperature?

At T_C = 100 °C, the continuous drain current is derated to 9.5 A. The SOA curve (Figure 1) shows pulse-width-limited operation beyond 1 ms; for 10 ms pulses, maximum V_DS drops to ~200 V at 15 A, constrained by R_DS(on) heating and thermal runaway limits.
