Product details
Overview
STF7NM60N from STMicroelectronics is an N-channel 600 V, 800 mΩ typ. (900 mΩ max.), 5 A MDmesh™ II Power MOSFET in IPAK (TO-251) package. It delivers low gate charge (14 nC), low input capacitance (363 pF), and 100% avalanche tested ruggedness for high-efficiency flyback and PFC converters operating at 65–100 kHz.
For engineers reviewing the STF7NM60N datasheet, STF7NM60N pinout, STF7NM60N application, or STF7NM60N equivalent, key selection criteria include its 2.78 °C/W junction-to-case thermal resistance, 15 V/ns dv/dt immunity, 119 mJ single-pulse avalanche energy, and suitability for industrial SMPS, LED drivers, and AC-DC adapters requiring reliable 600 V switching.
Technical Context
This device uses ST's second-generation MDmesh vertical strip architecture to minimize RDS(on) × Qg figure-of-merit-achieving 800 mΩ typ. at 10 VGS with only 14 nC total gate charge. Its optimized Crss (1.1 pF) and Coss eq. (130 pF) support fast, low-loss hard-switching.
The integrated body diode exhibits 1.3 V forward voltage at 5 A and 213 ns reverse recovery time (TJ = 25 °C), enabling efficient discontinuous conduction mode (DCM) operation. Safe operating area (SOA) is validated up to 10 ms at TC = 25 °C with 600 VDS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 600 V - Supports full-range universal AC input (85–265 VAC) with ≥2× safety margin in offline SMPS |
| RDS(on) max | 900 mΩ - Enables <5 W conduction loss at 5 A DC in TO-251 footprint without forced cooling |
| Qg | 14 nC - Reduces gate drive power and enables use of low-cost 100 mA gate drivers |
| EAS | 119 mJ - Withstands unclamped inductive switching events in PFC boost stages without failure |
| RthJC | 2.78 °C/W - Allows 35 W continuous dissipation at TC = 100 °C with minimal heatsink |
| dv/dt immunity | 15 V/ns - Prevents false turn-on during high-speed switching in noisy industrial environments |
| ISD | 5 A - Supports synchronous rectification or bootstrap supply in half-bridge topologies |
Pinout & Package
IPAK (TO-251) type C package: 3-pin surface-mount outline with exposed drain tab (pin 2/TAB) for enhanced thermal transfer. Tab is electrically connected to drain.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TAB (Pin 2) | Drain (D) | Primary current path and thermal interface; must be soldered to large copper pour for RthJC optimization |
| Pin 1 | Gate (G) | High-impedance control node; requires <5.4 Ω series resistance to damp ringing from 363 pF Ciss |
| Pin 3 | Source (S) | Reference node for gate drive and current sensing; connects to power ground plane |
Key Features
| Feature | Design Value |
|---|---|
| 100% avalanche tested | Guarantees robustness against inductive energy spikes in PFC and flyback snubberless designs |
| Low Ciss and Qg | 363 pF input capacitance and 14 nC gate charge enable >200 kHz operation with minimal driver loss |
| MDmesh™ II structure | Vertical strip layout achieves industry-leading RDS(on) × Qg = 1.27 Ω·nC for high-frequency efficiency |
| Low gate input resistance | 5.4 Ω intrinsic RG simplifies gate loop design and reduces risk of oscillation |
Applications
| Industrial SMPS | LED Driver |
|---|---|
Use Scenario: 150 W open-frame power supply for factory automation controllers. IC Role / Device Role / Timing Role: Primary-side switch in quasi-resonant flyback topology operating at 65 kHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP7NM60N | TO-220 package, identical electrical specs, higher RthJA (62 °C/W vs 100 °C/W) | Better suited for through-hole prototyping or lower-power designs with heatsink access | Select when mechanical mounting flexibility outweighs surface-mount density requirements |
| FQP7N60C | 600 V, 1.2 Ω RDS(on), 18 nC Qg, TO-220 - higher conduction + switching loss | Acceptable for cost-sensitive 30–50 W adapters where efficiency >88% is not mandatory | Choose only if STF7NM60N lead time exceeds 12 weeks and thermal budget permits 30% higher losses |
Compared with STP7NM60N and FQP7N60C, STF7NM60N offers superior power density via IPAK packaging, 22% lower RDS(on), and 22% lower Qg, making it optimal for compact, high-efficiency 50–150 W industrial power supplies where board space and thermal management are constrained.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
The STF7NM60N supports 3 A continuous drain current at TC = 100 °C, as specified in Table 1 of DS6523 Rev 6. This derating reflects thermal limitations of the IPAK package, not silicon capability-pulse current remains 20 A regardless of temperature.
Does STF7NM60N have a fully rated body diode for synchronous rectification?
No-the integrated body diode is rated for 5 A continuous and 20 A pulsed source-drain current, but its 213 ns reverse recovery time and 1.5 µC Qrr make it unsuitable for synchronous rectification above 50 kHz. External Schottky or MOSFETs are required for high-frequency SR.
Can STF7NM60N replace STU7NM60N in existing designs?
Yes-STF7NM60N and STU7NM60N share identical electrical specifications, thermal data, and pinout. The difference is packaging: STU7NM60N uses IPAK type A (obsolete), while STF7NM60N uses IPAK type C per DS6523 Rev 6. Mechanical compatibility must be verified using updated footprint dimensions.
What gate resistor value is recommended for 100 kHz QR flyback operation?
A 10 Ω gate resistor is recommended for 100 kHz QR flyback use, balancing switching speed (td(on)/td(off) ≈ 7/26 ns) and EMI suppression. This value damps ringing from the 363 pF Ciss and 5.4 Ω intrinsic RG, preventing overshoot beyond ±25 VGS absolute maximum rating.
