STMicroelectronics STL12N60M2

Overview

STL12N60M2 from STMicroelectronics is an N-channel 600 V, 0.400 Ω typ. R_DS(on), 6.5 A Power MOSFET in PowerFLAT 5x6 HV package, featuring MDmesh™ M2 technology, 16 nC total gate charge, and 100% avalanche tested for robustness in high-efficiency SMPS and PFC stages.

For engineers reviewing the STL12N60M2 datasheet, STL12N60M2 pinout, STL12N60M2 application, or STL12N60M2 equivalent, key selection criteria include its 2.4 °C/W junction-to-case thermal resistance, 50 V/ns MOSFET dv/dt ruggedness, 284 ns diode reverse recovery time at 150 °C, and Zener-protected gate for ESD resilience in industrial power converters.

Technical Context

This device employs ST's MDmesh™ M2 vertical superjunction architecture with strip layout to achieve low R_DS(on) × Q_g figure-of-merit (0.400 Ω × 16 nC = 6.4 Ω·nC), optimized for hard-switched and resonant topologies operating up to 100 kHz. Its C_oss eq. of 106 pF enables predictable turn-off energy and reduced voltage overshoot during inductive switching.

The integrated source-drain diode delivers 9 A continuous forward current with 1.6 V V_SD at 9 A and controlled reverse recovery (Q_rr = 2.4 µC at T_j = 25 °C), supporting synchronous rectification and flyback snubberless designs without external diode supplementation.

Key Specifications

Pinout & Package

STL12N60M2 uses the PowerFLAT 5x6 HV package - a surface-mount, thermally enhanced, leadless package with exposed drain pad on bottom side for direct PCB thermal coupling. The package features 5 mm × 6 mm footprint, 1.0 mm nominal height, and 8-pin configuration (3 drain pins, 1 source pin, 1 gate pin, 3 thermal pads tied to drain).

FAQ

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

The STL12N60M2 supports 4.1 A continuous drain current at T_case = 100 °C, as specified in Table 2 of the datasheet. This derating reflects thermal limits imposed by the 2.4 °C/W junction-to-case resistance and 150 °C maximum junction temperature, ensuring safe operation without forced cooling in enclosed enclosures.

Does this MOSFET include an integrated body diode, and what are its recovery characteristics?

Yes, STL12N60M2 integrates a source-drain diode rated for 9 A continuous and 36 A pulsed current. At 25 °C, its reverse recovery time is 284 ns with 2.4 µC Q_rr; at 150 °C, trr increases to 404 ns and Q_rr to 3.5 µC. These values are measured under standardized conditions (ISD = 9 A, di/dt = 100 A/µs, VDD = 60 V) and support snubberless flyback and LLC designs.

Can STL12N60M2 be driven directly by a 3.3 V microcontroller GPIO?

No - the gate threshold voltage (V_GS(th)) ranges from 2 V to 4 V, but full enhancement requires V_GS ≥ 10 V to achieve the specified 0.400 Ω R_DS(on). A 3.3 V signal yields high on-resistance and excessive conduction loss. A dedicated gate driver (e.g., STGAP2SICSN) or level-shifting circuit is required for reliable switching.

Is the PowerFLAT 5x6 HV package RoHS-compliant and halogen-free?

Yes - STL12N60M2 is offered in ECOPACK®2-compliant PowerFLAT 5x6 HV packaging, meeting RoHS Directive 2011/65/EU and IEC 61249-2-21:2011 for halogen-free materials. The device carries the "E2" ECOPACK® grade marking, indicating full compliance with ST's environmental standards and suitability for green manufacturing processes.
