STMicroelectronics STO67N60DM6

Overview

STO67N60DM6 from STMicroelectronics is a high-voltage N-channel Power MOSFET in the MDmesh DM6 fast-recovery diode series, rated at 600 V V_DS, 46 mΩ typ. R_DS(on), and 55 A continuous drain current. It features an integrated fast-recovery body diode (t_rr = 130 ns, Q_rr = 0.6 µC), low gate charge (Q_g = 74 nC), and Zener-protected gate, optimized for ZVS phase-shift converters and high-efficiency bridge topologies.

For engineers reviewing the STO67N60DM6 datasheet, STO67N60DM6 pinout, STO67N60DM6 application, or STO67N60DM6 equivalent, key selection criteria include its 100 V/ns dv/dt ruggedness, 0.35 °C/W R_thJC, TO-LL package thermal performance, and verified avalanche capability (E_AS = 800 mJ).

Technical Context

This device implements ST's MDmesh DM6 silicon architecture, combining ultra-low Q_rr and t_rr with reduced R_DS(on) per die area versus prior MDmesh generations. Its extra driving source pin (Pin 2) enables Kelvin-source sensing to minimize gate loop inductance and improve switching control fidelity.

The MOSFET supports hard-switched and resonant topologies requiring robust unclamped inductive switching (I_AR = 6 A, E_AS = 800 mJ) and high dv/dt immunity (100 V/ns) under V_DD ≤ 480 V conditions, with guaranteed operation up to T_J = 150 °C.

Key Specifications

Pinout & Package

FAQ

What is the purpose of the separate driver source pin (Pin 2)?

The driver source pin (Pin 2) provides a Kelvin connection for the gate driver's return path, isolating it from high di/dt power source currents. This eliminates voltage spikes across source inductance that cause false turn-on or oscillation, especially critical in ZVS and high-frequency hard-switched converters where gate control integrity directly impacts efficiency and reliability.

Can STO67N60DM6 replace older MDmesh D5 or DM2 devices?

Yes - STO67N60DM6 offers lower R_DS(on) (46 mΩ vs 65 mΩ for STW65N60DM2), faster diode recovery (130 ns vs 220 ns), and improved dv/dt ruggedness (100 V/ns vs 50 V/ns). Pin-compatible with TO-247 MDmesh D5/D2 in layout but requires verification of gate drive strength due to higher Q_g (74 nC vs ~50 nC).

Is the TO-LL package suitable for automated SMT assembly?

Yes - STO67N60DM6 is supplied in tape-and-reel packaging compliant with JEDEC standards and designed for standard reflow profiles. Its flat, symmetrical TO-LL outline and defined orientation in tape pocket (per Figure 23) ensure high-yield placement on PCBs using Class 7 pick-and-place equipment without tombstoning or misalignment.

How does the 100% avalanche test impact real-world reliability?

Each STO67N60DM6 unit undergoes single-pulse avalanche stress at I_AR = 6 A and E_AS = 800 mJ, verifying robustness against inductive energy dump during short-circuit or startup faults. This ensures field failure rates remain below 10 FIT in UPS and motor drive applications where unclamped inductive switching is routine, eliminating need for external clamping circuits.
