STMicroelectronics STP40N60M2

Overview

STP40N60M2 from STMicroelectronics is an N-channel 600 V, 78 mΩ typ., 34 A MDmesh™ M2 Power MOSFET in TO-220 package, designed for high-efficiency hard-switching and resonant-mode converters. It delivers low conduction loss (R_DS(on) = 78 mΩ typ.), ultra-low gate charge (Q_g = 57 nC), and rugged 100% avalanche-tested operation up to 500 mJ, enabling use in industrial SMPS, solar inverters, and UPS systems.

For engineers reviewing the STP40N60M2 datasheet, STP40N60M2 pinout, STP40N60M2 application, or STP40N60M2 equivalent, key selection criteria include its 600 V V_DS, 34 A I_D rating at T_C = 25 °C, 50 V/ns MOSFET dv/dt ruggedness, C_oss = 117 pF, and Zener-protected gate structure - all critical for reliable high-voltage switching design.

Technical Context

This device employs ST's MDmesh™ M2 strip-based silicon architecture with optimized vertical charge balancing, yielding a superior R_DS(on) × Q_g figure of merit. Its C_oss profile remains stable across voltage, supporting soft-switching topologies like LLC and phase-shifted full-bridge.

The integrated body diode features low reverse recovery charge (Q_rr = 8.2 µC typ.) and fast trr = 440 ns at 100 A/µs, reducing switching losses in synchronous rectification and bidirectional power flow applications. The ±25 V V_GS rating and 4.4 Ω intrinsic gate resistance support robust gate drive design.

Key Specifications

Pinout & Package

STP40N60M2 uses the TO-220 package (Type A), with metal tab electrically connected to the drain terminal. Mounting requires insulated hardware or thermal pad due to direct drain-to-case connection.

FAQ

What is the maximum continuous drain current at 100 °C case temperature?

The STP40N60M2 supports 22 A continuous drain current (I_D) at T_C = 100 °C, as specified in Table 1 of DS9801 Rev 5. This derating reflects thermal limits of the TO-220 package, not silicon capability - the die itself sustains 34 A at 25 °C case, and safe operating area curves confirm 22 A remains within R_DS(on)-limited boundaries at 100 °C.

Does STP40N60M2 require external gate protection?

No - STP40N60M2 integrates a Zener diode between gate and source, clamping V_GS to ±25 V absolute maximum. This eliminates the need for external TVS diodes in most layouts, provided PCB trace inductance is minimized to limit L_g × di/dt overshoot. Gate resistor selection (typically 4.7–10 Ω) remains essential for controlling dv/dt and oscillation damping.

How does its avalanche rating compare to STP30N60M2?

STP40N60M2 specifies E_AS = 500 mJ (single-pulse, T_J = 25 °C), while STP30N60M2 (older generation) rates 320 mJ. The 56% higher energy rating stems from MDmesh™ M2's improved vertical charge distribution and thicker epitaxial layer, verified by 100% production avalanche testing per DS9801 Section 3.

Can STP40N60M2 replace STP40NF10 in existing designs?

No - STP40NF10 is a 100 V, 40 A logic-level MOSFET with V_GS(th) ≈ 2–4 V and R_DS(on) = 33 mΩ, incompatible with 600 V systems. STP40N60M2 requires 10 V gate drive, has 6× higher V_DS, and serves entirely different voltage classes. Direct substitution would cause catastrophic failure under 400 V bus conditions.
