Product details
Overview
STL7N60M2 from STMicroelectronics is an N-channel 600 V, 5 A Power MOSFET using MDmesh™ M2 technology in a PowerFLAT™ 5x5 package. It delivers 0.92 Ω typ. RDS(on), 8.8 nC total gate charge, and 15 V/ns diode recovery dv/dt ruggedness-enabling high-efficiency flyback and PFC stages in industrial AC-DC power supplies.
For engineers reviewing the STL7N60M2 datasheet, STL7N60M2 pinout, STL7N60M2 application, or STL7N60M2 equivalent, key selection criteria include its 1.05 Ω max RDS(on) at 10 VGS, 150 °C max junction temperature, Zener-protected gate, and 100% avalanche tested reliability for hard-switched topologies.
Technical Context
This device employs ST's MDmesh™ M2 strip-based vertical structure to minimize conduction loss while optimizing switching performance. Its low Coss (15.7 pF typ.) and ultra-low Qgd/Qgs ratio (4.3/1.8 nC) reduce switching losses and improve EMI behavior in high-frequency SMPS designs.
The integrated Zener-protected gate withstands ±25 V transient stress, and the 80 mJ single-pulse avalanche energy rating supports unclamped inductive switching. Its 31.3 °C/W Rthj-pcb enables thermal management on standard FR-4 PCBs without heatsinks in ≤1.2 A continuous Tpcb applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
STL7N60M2 uses the PowerFLAT™ 5x5 surface-mount package (ECOPACK® compliant), measuring 5.0 × 5.0 × 1.0 mm with exposed drain pad for thermal conduction. Pin 1 is marked by a notch on the top side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect | Internally isolated; must remain floating or grounded per layout guidelines |
| 2, 3, 4, 7, 8, 9 | Source | Common source terminals tied to internal die; low-inductance parallel routing required |
| 5, 6, 11, 12 | Drain | Exposed drain pad + four perimeter pins - primary thermal path to PCB copper |
| 10 | Gate | Single gate input; requires RC snubber if driving >100 kHz due to 7.2 Ω intrinsic RG |
Key Features
| Feature | Design Value |
|---|---|
| MDmesh™ M2 technology | Optimized strip layout reduces RDS(on) × area product by 35% vs prior generation |
| Zener-protected gate | Integrated 25 V bidirectional clamp eliminates need for external gate protection diodes |
| 100% avalanche tested | Each unit validated for single-pulse EAS ≥ 80 mJ - ensures robustness in overcurrent events |
| Low Coss profile | 15.7 pF typ. output capacitance minimizes turn-off loss and improves ZVS capability |
| PowerFLAT™ 5x5 package | 0.83 °C/W Rthj-case enables >67 W dissipation with minimal footprint and no leads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPP60R190C6 | 650 V, 190 mΩ RDS(on), TO-220FP package, higher Qg (29 nC) | Requires heatsink; better suited for lower-frequency, higher-current (<10 A) designs | Choose when board space allows through-hole mounting and thermal mass is available |
| STW20NK60Z | 600 V, 200 mΩ RDS(on), TO-247 package, Zener-protected, but higher Coss (110 pF) | Higher switching loss; used in legacy 50–100 kHz fixed-frequency converters | Prefer only when replacing obsolete designs where layout and drive circuitry are unchanged |
Compared with IPP60R190C6 and STW20NK60Z, STL7N60M2 offers superior power density and high-frequency efficiency due to its 5x5 package, lower Qg, and optimized Coss profile-making it optimal for space-constrained, >100 kHz SMPS where thermal interface to PCB is primary cooling path.

FAQ
What is the maximum continuous drain current at PCB temperature of 100 °C?
The STL7N60M2 supports 0.8 A continuous drain current when mounted on a 1-inch² FR-4 PCB with 2 oz copper at 100 °C PCB temperature. This rating reflects its 31.3 °C/W junction-to-PCB thermal resistance and is validated under pulsed conditions (t < 10 s, 1.5% duty cycle).
Does STL7N60M2 require external gate protection?
No. The device integrates a bidirectional Zener diode between gate and source, rated for ±25 V, eliminating the need for external gate protection components in standard gate drive configurations. This simplifies layout and improves system reliability against ESD and transient overvoltage.
Can STL7N60M2 be used in avalanche mode repeatedly?
Yes. Each unit undergoes 100% production avalanche testing at IAR = 1 A and EAS = 80 mJ (single pulse, Tj = 25 °C). Repetitive avalanche operation is permitted within SOA limits defined in Figure 2, provided peak junction temperature remains below 150 °C and pulse width is constrained by thermal time constants.
What is the recommended PCB footprint for thermal performance?
ST recommends a minimum 200 mm² exposed copper area connected to pins 5/6/11/12 and the bottom drain pad, with ≥4 thermal vias (0.3 mm diameter, 0.8 mm pitch) to inner ground plane. Figure 21 in DocID027417 Rev 1 specifies exact dimensions: 4.05–4.25 mm D1 width and 2.25–2.45 mm E2 length for solder mask opening.
