STMicroelectronics STP13N65M2

Overview

STP13N65M2 from STMicroelectronics is an N-channel 650 V, 430 mΩ (max), 10 A Power MOSFET using MDmesh M2 technology in TO-220 package. It delivers low gate charge (17 nC), optimized Coss profile (27.5 pF typ.), and 100% avalanche-tested ruggedness for high-efficiency flyback and PFC converters operating up to 100 °C case temperature.

For engineers reviewing the STP13N65M2 datasheet, STP13N65M2 pinout, STP13N65M2 application, or STP13N65M2 equivalent, key selection criteria include RDS(on) stability over temperature, dv/dt ruggedness (50 V/ns), single-pulse avalanche energy (350 mJ), and Zener-protected gate reliability in hard-switching SMPS designs.

Technical Context

This MOSFET employs a strip-layout MDmesh M2 vertical structure to minimize conduction loss while maintaining fast switching via low Crss (1.1 pF) and controlled Qgd/Qgs ratio (7/3.3 nC). Its Coss eq. of 168.5 pF (0–520 V) enables predictable turn-off timing in high-voltage resonant topologies.

The device integrates a Zener-protected gate oxide and is rated for 15 V/ns diode recovery dv/dt and 50 V/ns MOSFET dv/dt ruggedness under defined conditions (VDD ≤ 520 V, ISD ≤ 10 A). Junction-to-case thermal resistance is 1.14 °C/W, supporting 110 W continuous dissipation at TC = 25 °C.

FAQ

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

The STP13N65M2 supports 6.3 A continuous drain current at TC = 100 °C, as specified in Table 1 of DS10587 Rev 2. This derating reflects thermal limitations of the TO-220 package with RthJC = 1.14 °C/W; operation above this current requires forced-air cooling or heatsink optimization.

Does the device include integrated gate protection?

Yes-the STP13N65M2 features an integrated Zener diode between gate and source that clamps VGS to ±25 V, protecting the gate oxide from overvoltage during layout parasitics or driver faults. This eliminates the need for external gate Zener diodes in most AC-DC adapter and industrial SMPS designs.

How is avalanche ruggedness verified for this MOSFET?

Every STP13N65M2 unit undergoes 100% production avalanche testing per JEDEC JESD22-A109, measuring single-pulse EAS ≥ 350 mJ at TJ = 25 °C with ID = 1.8 A and VDD = 50 V. Test conditions are documented in Table 3 of DS10587 Rev 2 and validated on ST's automated test equipment.

Can STP13N65M2 replace STP12N65M2 in existing designs?

Yes-STP13N65M2 is a direct upgrade from STP12N65M2 with identical TO-220 package, pinout, and gate drive requirements. It offers 15% lower RDS(on) (430 mΩ vs. 500 mΩ max) and improved Coss profile, enabling higher efficiency without layout changes or gate driver requalification.
