Product details
Overview
STFU26N60M2 from STMicroelectronics is an N-channel 600 V, 140 mΩ typ., 20 A MDmesh™ M2 Power MOSFET in TO-220FP ultra narrow leads package, optimized for high-efficiency LLC resonant converters and hard-switching SMPS. It features 34 nC total gate charge, 88 pF output capacitance, and 100% avalanche tested ruggedness with Zener-protected gate.
For engineers reviewing the STFU26N60M2 datasheet, STFU26N60M2 pinout, STFU26N60M2 application, or STFU26N60M2 equivalent, key selection criteria include its 50 V/ns MOSFET dv/dt ruggedness, 250 mJ single-pulse avalanche energy, low Coss profile, and thermal resistance of 4.2 °C/W (junction-to-case).
Technical Context
This MOSFET employs ST's MDmesh M2 strip layout and enhanced vertical structure to simultaneously reduce RDS(on) and optimize switching losses. Its 124 pF equivalent output capacitance (Coss,eq) across 0–480 V enables predictable soft-switching behavior in resonant topologies.
The device integrates a robust body diode with 360 ns reverse recovery time at 25 °C and 556 ns at 150 °C, supporting high-frequency operation in bridge configurations. Gate threshold voltage (2–4 V) and ±25 V gate-source rating ensure compatibility with standard 10 V gate drivers while maintaining noise immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 600 V - supports primary-side switching in 400 V DC bus and universal AC input offline converters |
| RDS(on) max | 165 mΩ at VGS = 10 V, ID = 10 A - enables <1.7 W conduction loss at 20 A continuous drain current |
| Qg | 34 nC - reduces driver power demand and enables fast turn-on with low gate resistance (<5 Ω) |
| Coss | 88 pF at VDS = 100 V - contributes to low stored output energy (EOSS = 10 µJ at 400 V) |
| EAS | 250 mJ - provides margin against unclamped inductive switching stress without external snubbers |
| TJ max | 150 °C - allows operation in thermally constrained industrial and server PSU environments |
| RthJC | 4.2 °C/W - enables 30 W dissipation at ≤25 °C case temperature, critical for compact heatsink designs |
Pinout & Package
Package: TO-220FP ultra narrow leads - insulated case, 3-pin through-hole, 10.4 mm height, 30.5 mm length, designed for high-voltage isolation and PCB space efficiency.
| Pin/Terminal | Circuit Role | Design Meaning |

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 |
|---|---|---|---|
| STW26N60M2 | TO-247 package, identical die, higher RthJA (62.5 °C/W vs. 4.2 °C/W), no insulated case | Requires external isolation for heatsink mounting; better suited for forced-air-cooled industrial inverters | Select when higher power dissipation (>45 W) and mechanical robustness outweigh PCB space constraints |
| IPP60R190C7 | 600 V, 190 mΩ, 21 A, CoolMOS C7; lower Qg (25 nC) but higher Coss (110 pF) | Superior light-load efficiency in DCM flyback; less optimal for LLC due to Coss nonlinearity | Select for cost-sensitive consumer PSUs where ZVS margin is less critical than BOM count reduction |
Compared with STW26N60M2 and IPP60R190C7, STFU26N60M2 uniquely balances low Coss, tight Qg, and insulated TO-220FP packaging-making it optimal for space-constrained, high-reliability LLC and industrial PFC designs where thermal interface simplicity and voltage isolation are mandatory.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
The STFU26N60M2 supports 13 A continuous drain current at TC = 100 °C, as specified in Table 1 of DS12254 Rev 2. This derating reflects thermal limits of the TO-220FP package and ensures safe operation within SOA boundaries at elevated ambient temperatures.
Does this MOSFET require a negative gate turn-off voltage?
No. The STFU26N60M2 has a gate threshold voltage of 2–4 V and is fully compatible with 0 V/10 V gate drive. Its ±25 V VGS rating and Zener protection eliminate the need for negative turn-off bias, simplifying driver design in half-bridge and LLC applications.
How does the 2.5 kV insulation withstand voltage impact PCB layout?
The 2.5 kV RMS insulation rating between all three leads and the external heat sink allows direct mounting to grounded metal chassis without additional insulating hardware. This reduces thermal interface layers, lowers RthJC, and simplifies creepage/clearance compliance for EN 62368-1 in high-voltage industrial designs.
Is the body diode suitable for synchronous rectification?
No-the internal body diode is not optimized for synchronous rectification. Its 360 ns trr and 5 µC Qrr at 25 °C indicate moderate recovery performance. For SR applications, use dedicated low-Qrr MOSFETs or external Schottky diodes to avoid cross-conduction and reverse recovery loss.
