Product details
Overview
STF28N60DM2 from STMicroelectronics is a high-voltage N-channel MDmesh™ DM2 Power MOSFET in TO-220FP package, rated 600 V V(BR)DSS, 0.13 Ω typ. RDS(on), 21 A continuous drain current, and featuring fast-recovery body diode (trr = 140 ns @ Tj = 25 °C), low Qg (34 nC), and Zener-protected gate. It is engineered for high-efficiency bridge and ZVS phase-shift converters.
For engineers reviewing the STF28N60DM2 datasheet, STF28N60DM2 pinout, STF28N60DM2 application, or STF28N60DM2 equivalent, key selection criteria include avalanche ruggedness (EAS = 350 mJ), dv/dt immunity (50 V/ns), thermal resistance (Rthj-case = 4.2 °C/W), and fast diode recovery performance in hard-switched topologies.
Technical Context
This device implements ST's MDmesh™ DM2 silicon technology optimized for high-voltage switching with integrated fast-recovery body diode. Its low Qrr (0.5 µC @ 25 °C) and trr reduce switching losses in resonant and phase-shifted full-bridge converters, while the built-in back-to-back gate-source Zener diodes (±30 V breakdown) provide ESD robustness without external clamping.
The MOSFET operates with VGS(th) between 3–5 V and maintains stable RDS(on) up to 125 °C case temperature. Its SOA is defined up to 100 °C case, supporting reliable operation under repetitive unclamped inductive switching with IAR = 4 A and VDD ≤ 480 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 600 V - Sustains 600 V drain-source blocking voltage before avalanche onset, enabling use in 400 V DC bus systems with margin. |
| RDS(on) max | 0.16 Ω - Limits conduction loss to ≤3.5 W at 21 A, critical for thermal management in enclosed power supplies. |
| Qg | 34 nC - Enables fast, low-loss switching with standard gate drivers; reduces driver power demand and layout complexity. |
| trr | 140 ns - Minimizes reverse recovery loss and EMI generation during hard commutation in LLC and PSFB converters. |
| EAS | 350 mJ - Supports single-pulse unclamped inductive energy handling without failure, enhancing system reliability. |
| Rthj-case | 4.2 °C/W - Allows 30 W dissipation with ≤126 °C junction rise above 25 °C case, defining heatsink sizing requirements. |
| dv/dt ruggedness | 50 V/ns - Withstands rapid voltage transients across drain-source during turn-off, reducing risk of spurious turn-on. |
Pinout & Package
STF28N60DM2 uses the TO-220FP (Full-Pak) package: insulated plastic case with integral heatsink tab, 3-pin vertical mounting configuration, and creepage/clearance compliant with 2.5 kV RMS isolation rating between leads and heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path to heatsink | Electrically connected to metal tab; must be isolated from chassis unless referenced to system ground; carries full load current. |
| Source | Reference node for gate drive and current sensing | Low-side return path; used for shunt-based current monitoring and gate drive reference; common to internal body diode cathode. |
| Gate | Control terminal for channel conduction | High-impedance input requiring <34 nC charge for full enhancement; protected by ±30 V Zener diodes to prevent ESD damage. |
Key Features
| Feature | Design Value |
|---|---|
| Fast-recovery body diode | trr = 140 ns and Qrr = 0.5 µC enable efficient operation in synchronous rectification and bidirectional topologies without external diode. |
| Low gate charge | Qg = 34 nC reduces switching transition time and driver losses, allowing use with low-power gate drivers like STGAP2SIC. |
| Zener-protected gate | Integrated ±30 V gate-source Zener diodes eliminate need for external TVS, simplifying layout and improving ESD immunity per IEC 61000-4-2 Level 4. |
| 100% avalanche tested | Each unit validated for single-pulse avalanche energy (EAS = 350 mJ), ensuring robustness in overvoltage fault conditions. |
| High dv/dt ruggedness | Rated 50 V/ns ensures immunity to parasitic turn-on in high-frequency half-bridge configurations with fast edge rates. |

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 |
|---|---|---|---|
| IPP60R190C7 | RDS(on) = 0.19 Ω, Qg = 35 nC, trr = 180 ns, TO-220 package (non-isolated tab) | Lacks Zener gate protection and 2.5 kV isolation; higher RDS(on) increases conduction loss by ~46% | Prefer when cost sensitivity outweighs isolation and ESD robustness requirements. |
| STW28N60DM2 | Same die, TO-247 package; Rthj-case = 0.45 °C/W vs 4.2 °C/W; no built-in Zener diodes | Enables higher power density but requires external gate clamping and larger heatsink footprint | Select for >100 W continuous dissipation where thermal headroom justifies TO-247 mechanical redesign. |
Compared with IPP60R190C7 and STW28N60DM2, STF28N60DM2 uniquely combines gate Zener protection, 2.5 kV isolation, and optimized Qrr/RDS(on) trade-off-making it ideal for space-constrained, safety-critical industrial and EV auxiliary power designs where reliability and layout simplicity are prioritized over raw power density.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
The STF28N60DM2 supports 14 A continuous drain current at Tcase = 100 °C, as specified in Table 2 of the datasheet. This derating reflects thermal limits imposed by its 4.2 °C/W junction-to-case resistance and 150 °C maximum junction temperature, ensuring safe operation without exceeding SOA boundaries.
Does the TO-220FP package provide electrical isolation between leads and heatsink?
Yes-the TO-220FP package features reinforced insulation with 2.5 kV RMS withstand voltage (1 s, 25 °C) between all three leads and the external heatsink, verified per IEC 60747-5-2. This eliminates need for insulating pads in many industrial applications, though creepage distance must still comply with end-equipment safety standards.
How does the built-in Zener diode protect the gate?
The integrated back-to-back gate-source Zener diodes clamp transient voltages to ±30 V, preventing gate oxide breakdown during ESD events or gate driver overshoot. This replaces external TVS components, reduces PCB area, and improves system-level IEC 61000-4-2 compliance without sacrificing switching speed or gate drive integrity.
Can STF28N60DM2 replace STW28N60DM2 in existing designs?
No direct drop-in replacement: STF28N60DM2 uses TO-220FP (insulated tab, lower power dissipation), while STW28N60DM2 uses TO-247 (non-insulated tab, 0.45 °C/W Rthj-case). Mechanical fit, thermal design, and gate drive layout differ significantly; redesign is required to accommodate lower thermal capability and isolation requirements of the TO-220FP variant.
