Product details

Overview

STF15NM60N from STMicroelectronics is an N-channel 600 V, 14 A, 0.270 Ω R_DS(on) Power MOSFET in TO-220FP package, implementing second-generation MDmesh™ technology for high-efficiency switching converters. It delivers low gate charge (37 nC), low input capacitance (1250 pF), and 100% avalanche-tested ruggedness, enabling use in industrial AC-DC SMPS and PFC stages.

For engineers reviewing the STF15NM60N datasheet, STF15NM60N pinout, STF15NM60N application, or STF15NM60N equivalent, key selection criteria include its 600 V V_DSS, 0.270 Ω R_DS(on) at V_GS = 10 V, 37 nC total gate charge, TO-220FP thermal resistance (R_thj-case = 4.2 °C/W), and unclamped inductive switching capability.

Technical Context

This MOSFET uses ST's second-generation MDmesh™ vertical structure combined with strip layout to minimize conduction and switching losses simultaneously. Its 600 V breakdown voltage and 14 A continuous drain current (at T_C = 25°C) support operation in universal-input offline converters up to 3 kW.

The device features a fast source-drain diode with t_rr = 390 ns (T_j = 25°C) and Q_rr = 5 µC, enabling hard-switched bridge configurations. Gate threshold voltage (2–4 V) and low gate input resistance (6.0 Ω) ensure robust drive compatibility with standard 10 V gate drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	600 V - Withstands full rectified 400 VAC line surges in offline applications without breakdown
R_DS(on)	0.270 Ω @ V_GS = 10 V - Enables <1.5 W conduction loss at 14 A, critical for thermal management in compact designs
Q_g	37 nC - Reduces gate drive power and enables higher PWM frequencies (>100 kHz) with standard drivers
C_iss	1250 pF - Low input capacitance minimizes Miller effect and improves switching stability under high dv/dt
t_r/t_f	14 ns / 30 ns @ R_G = 4.7 Ω - Fast edge rates reduce switching transition losses in hard-switched topologies
E_AS	300 mJ - Supports reliable unclamped inductive switching in flyback and resonant converters
R_thj-case	4.2 °C/W - Allows 125 W dissipation with ≤50°C case-to-ambient rise, suitable for heatsink-limited industrial enclosures

Pinout & Package

STF15NM60N is housed in a TO-220FP (Full-Pak) package - a variant of TO-220 with insulated backside, eliminating need for mounting insulator while maintaining mechanical compatibility. The package provides creepage/clearance compliance for reinforced insulation in safety-critical AC-DC systems.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Power return path for load current	Internally connected to exposed tab; electrically tied to PCB ground plane for low-inductance return and thermal conduction
2 (Gate)	Control terminal for channel modulation	High-impedance MOS gate requiring <100 nA leakage; sensitive to ESD; routed away from noisy power traces
3 (Drain)	Main high-side power terminal	Connected to internal die backside; forms primary high-voltage node; requires minimum 2.5 mm creepage to other conductors

Key Features

Feature	Design Value
Second-generation MDmesh™ structure	Combines low R_DS(on) and low C_iss to achieve best-in-class figure-of-merit (R_DS(on) × Q_g = 10.0 nΩ·F) for 600 V class
100% avalanche rated	Guarantees single-pulse energy handling up to 300 mJ without parameter shift-critical for PFC overvoltage events
Low gate input resistance	6.0 Ω enables stable gate waveform integrity and reduces risk of oscillation during turn-on/turn-off transitions
ECOPACK® compliant	Lead-free second-level interconnect meets RoHS and JEDEC JESD97 standards; marked on package and inner box label
TO-220FP insulated package	Eliminates need for silicone pad or mica insulator-reducing thermal resistance by ~0.5 °C/W vs. standard TO-220 with insulator

Applications

Industrial AC-DC SMPS

Active PFC Stage

Use Scenario: 1–3 kW open-frame power supply for PLCs and motor drives operating from 85–265 VAC input.

IC Role / Device Role / Timing Role: Main switch in continuous conduction mode (CCM) boost converter, switching at 65–100 kHz.

Use Value: 0.270 Ω R_DS(on) and 37 nC Q_g jointly reduce total losses below 3.2 W at full load, enabling >94% efficiency without forced air cooling.

Use Scenario: Front-end power factor correction in telecom rectifiers and server PSUs.

IC Role / Device Role / Timing Role: High-side switch in interleaved CCM boost stage, synchronized to 100–200 kHz carrier.

Use Value: Low C_oss (100 pF) and fast t_r/t_f minimize dead-time losses and improve light-load efficiency across wide input range.

Solar Microinverters

UPS Inverter Stage

Use Scenario: DC-AC H-bridge stage in single-phase 250–500 W microinverters interfacing PV panels to grid.

IC Role / Device Role / Timing Role: Low-side switch in unipolar PWM topology, operating at 16–20 kHz with sinusoidal output filtering.

Use Value: Avalanche ruggedness (E_AS = 300 mJ) withstands inductive kickback from transformer-coupled output filters during fault conditions.

Use Scenario: Half-bridge in-line inverter in 1–2 kVA online UPS systems with battery backup.

IC Role / Device Role / Timing Role: High-efficiency switching element in 50/60 Hz fundamental-frequency or high-frequency link topology.

Use Value: TO-220FP insulation allows direct mounting to grounded heatsink-simplifying safety certification and reducing BOM count by eliminating insulating hardware.

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
STP15NM60N	Same die, TO-220 (non-insulated) package; R_thj-case = 1.0 °C/W but requires insulator	Preferred where heatsink isolation is already implemented and lower thermal resistance is prioritized	Select when mechanical design accommodates insulator and thermal budget demands sub-1°C/W junction-to-case resistance
FDPF15N60	ON Semiconductor part; 0.30 Ω R_DS(on), 42 nC Q_g, TO-220FP; slightly higher conduction and switching losses	Valid drop-in for cost-sensitive industrial supplies where 2–3% efficiency margin is acceptable	Choose when cross-manufacturer qualification is required and minor efficiency trade-off is permissible

Compared with STP15NM60N, STF15NM60N trades 3.2 °C/W higher thermal resistance for simplified mounting and safety compliance; versus FDPF15N60, it delivers measurable improvement in both conduction loss (−10%) and gate drive efficiency (−12% Q_g).

FAQ

What is the maximum continuous drain current at 100°C case temperature?

The STF15NM60N supports 9 A continuous drain current at T_C = 100°C, as specified in Table 1 of the datasheet. This derating reflects thermal limits of the TO-220FP package and ensures safe operation within SOA boundaries when heatsink temperature remains ≤100°C under sustained load.

Does STF15NM60N require a gate resistor for stable switching?

Yes-a gate resistor is required to control dV/dt and prevent parasitic oscillation. The datasheet specifies switching times using R_G = 4.7 Ω. Typical design values range from 2.2 Ω to 10 Ω depending on driver strength and EMI requirements; lower values increase switching speed but raise EMI risk and gate drive loss.

Can STF15NM60N be used in synchronous rectification?

No-it is not optimized for synchronous rectification. Its body diode recovery time (t_rr = 390 ns) and Q_rr (5 µC) are significantly higher than dedicated SR MOSFETs, leading to excessive reverse recovery loss. Use only as a controlled switch in hard- or resonant-switched topologies-not as a freewheeling diode replacement.

Is STF15NM60N suitable for automotive applications?

No-STF15NM60N is not qualified to AEC-Q101 and lacks automotive-grade screening, temperature range extension (−40°C to 175°C), or PPAP documentation. ST explicitly states non-automotive use unless designated "automotive grade"; this part is intended for industrial and commercial power systems only.
