Product details
Overview
STF20NM60D from STMicroelectronics is an N-channel 600 V, 20 A FDmesh™ Power MOSFET in TO-220FP package with integrated fast-recovery body diode, RDS(on) ≤ 0.29 Ω at VGS = 10 V, 192 W power dissipation at TC = 25 °C, and 100% avalanche tested - designed for high-efficiency ZVS phase-shift converters and bridge-leg switching.
For engineers reviewing the STF20NM60D datasheet, STF20NM60D pinout, STF20NM60D application, or STF20NM60D equivalent, key selection criteria include its 20 V/ns dv/dt capability, 700 mJ single-pulse avalanche energy, low 37 nC total gate charge, and optimized Coss (190 pF) for soft-switching topologies requiring robust diode recovery.
Technical Context
This MOSFET employs ST's FDmesh™ process to co-optimize conduction loss (RDS(on) = 0.26 Ω typ.), switching speed (tr = 12 ns, tf = 22 ns), and body diode performance (trr = 240 ns at 25 °C, Qrr = 1800 nC). Its 600 V VDSS, ±30 V VGS, and 10 A IAR avalanche rating support operation in hard- and resonant-switched SMPS.
The device integrates a fast-recovery intrinsic body diode with 1.5 V forward voltage at 20 A and tight thermal resistance (Rthj-case = 0.65 °C/W), enabling stable operation up to 150 °C junction temperature in high-power industrial and telecom power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 600 V - supports primary-side switching in 400 V DC bus and universal AC-input offline converters |
| RDS(on) max | 0.29 Ω at VGS = 10 V, TC = 25 °C - enables <1.2 W conduction loss at 20 A continuous drain current |
| ID cont | 20 A at TC = 25 °C - rated for sustained output stages in 500–1000 W power supplies |
| EAS | 700 mJ - ensures reliable unclamped inductive switching without external snubbers |
| Qg | 37 nC - reduces gate drive power and enables efficient operation with standard 1–2 A gate drivers |
| trr | 240 ns at Tj = 25 °C - minimizes commutation loss and EMI in synchronous rectification and half-bridge legs |
| Rthj-case | 0.65 °C/W - allows direct heatsink mounting with <13 °C temperature rise per 20 W dissipated |
Pinout & Package
STF20NM60D uses the TO-220FP (Full-Pak) package: insulated plastic case with internal isolation between drain tab and mounting surface, enabling direct heatsink attachment without insulating pads. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate terminal | High-impedance control input; requires ≤10 V drive for full enhancement; RG = 4.7 Ω used in switching characterization |
| Pin 2 (D) | Drain terminal (exposed metal tab) | Primary high-voltage node; electrically isolated from heatsink in TO-220FP; connects to DC bus or transformer primary |
| Pin 3 (S) | Source terminal | Power return path and gate reference; ties to low-side switch node or ground plane; source inductance critical for dV/dt immunity |
Key Features
| Feature | Design Value |
|---|---|
| FDmesh™ silicon architecture | Simultaneously optimizes RDS(on), Qg, and Coss - delivers 20% lower switching loss vs. prior-generation 600 V MOSFETs at same RDS(on) |
| Fast-recovery body diode | trr = 240 ns / Qrr = 1800 nC at 25 °C - eliminates need for external anti-parallel SiC Schottky in ZVS bridge legs |
| 100% avalanche tested | Each unit validated to 10 A IAR and 700 mJ EAS - guarantees ruggedness in overvoltage transients and startup faults |
| Low gate input resistance | RG = 2.7 Ω - improves noise immunity and reduces gate oscillation risk without external series resistor |
| ECOPACK® RoHS-compliant packaging | Lead-free second-level interconnect; JEDEC JESD97 marked; compatible with standard reflow profiles up to 260 °C peak |
Applications
| ZVS Phase-Shift Full-Bridge Converter | Industrial AC-DC Front-End |

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 |
|---|---|---|---|
| STW20NM60FD | TO-247 package, Rthj-case = 0.585 °C/W, PTOT = 214 W - higher power handling but larger footprint | Better suited for forced-air-cooled 1.5 kW+ designs where thermal headroom is critical | Select when board space permits and junction temperature must stay <125 °C at >18 A continuous |
| IPW60R037P7XKSA1 (Infineon) | 650 V, 0.037 Ω, TO-247-4L, CoolMOS™ C7 - lower RDS(on) but no integrated fast diode; requires external SiC diode | Optimized for hard-switched PFC; not recommended for ZVS bridges without added diode complexity | Prefer only if lowest conduction loss is priority and layout allows discrete diode integration |
Compared with STW20NM60FD and IPW60R037P7XKSA1, STF20NM60D offers the best balance of integrated fast-diode functionality, TO-220FP mechanical compatibility, and proven ZVS performance - making it optimal for space-constrained, medium-power bridge converters where diode recovery is critical.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
The STF20NM60D supports 12.6 A continuous drain current at TC = 100 °C, as specified in Table 1 of the official datasheet. This derating reflects thermal limits of the TO-220FP package and ensures safe operation within the 150 °C maximum junction temperature rating.
Does STF20NM60D require a gate resistor for stability?
A gate resistor is recommended: 4.7 Ω is used in the datasheet's switching time test circuit (Figure 16) to dampen ringing and control di/dt. While the device's low gate input resistance (2.7 Ω) improves noise immunity, omitting an external resistor may cause overshoot or oscillation with high-speed drivers.
Can STF20NM60D replace STP20NM60FD in existing designs?
Yes, with mechanical and thermal caveats: both share identical electrical specs (VDSS, RDS(on), ID), but STF20NM60D uses TO-220FP (isolated tab) versus STP20NM60FD's TO-220 (non-isolated tab). Heatsink insulation and mounting torque must be verified to maintain isolation integrity.
Is the body diode suitable for synchronous rectification?
No - the integrated body diode is optimized for freewheeling and ZVS recovery, not reverse conduction. Its 1.5 V forward drop and 240 ns recovery time exceed typical synchronous rectifier requirements; external low-VF Schottky or MOSFETs are required for secondary-side synchronous rectification.
