Product details

Overview

STF6N60M2 from STMicroelectronics is an N-channel 600 V, 1.06 Ω typ. (1.2 Ω max), 4.5 A MDmesh M2 Power MOSFET in TO-220FP package, optimized for high-efficiency flyback and PFC converters in industrial SMPS and AC-DC adapters.

For engineers reviewing the STF6N60M2 datasheet, STF6N60M2 pinout, STF6N60M2 application, or STF6N60M2 equivalent, key selection criteria include R_DS(on) at 10 V, C_oss profile (14 pF), Q_g (8 nC), avalanche ruggedness (86 mJ), and TO-220FP thermal resistance (6.25 °C/W).

Technical Context

This device uses ST's MDmesh M2 strip layout and enhanced vertical structure to achieve low conduction loss and fast switching with controlled dv/dt ruggedness (50 V/ns). Its Zener-protected gate enables robust gate drive design without external clamping.

The integrated body diode exhibits 1.6 V forward voltage at 4.5 A and 274 ns reverse recovery time at 25 °C, supporting hard-switched topologies requiring reliable unclamped inductive switching capability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - supports 400 V DC bus designs with 50% safety margin for surge and ringing
R_DS(on) max	1.2 Ω @ V_GS = 10 V, I_D = 2.25 A - defines conduction loss in continuous conduction mode PFC stages
Q_g	8 nC - determines gate driver power requirement and switching speed trade-off in 65–100 kHz converters
C_oss	14 pF - contributes to turn-off energy loss and impacts zero-voltage switching feasibility
E_AS	86 mJ - enables reliable operation under unclamped inductive load conditions without external snubbers
R_thJC	6.25 °C/W - sets maximum allowable power dissipation (20 W) at T_C = 25 °C for heatsink-limited designs

Pinout & Package

STF6N60M2 is housed in a TO-220FP (Full-Pak) package with insulated tab, enabling direct mounting to heatsinks without isolation hardware. The plastic body provides creepage/clearance compliance per IEC 60950-1.

Pin/Terminal	Circuit Role	Design Meaning
D (Tab)	Drain	High-side switching node; electrically connected to metal tab - requires insulation when mounted to grounded heatsink
G (Pin 1)	Gate	Control input; Zener-protected to ±25 V - tolerates transient overshoot without external TVS
S (Pin 3)	Source	Power return path; referenced to driver ground - critical for gate loop inductance minimization

Key Features

Feature	Design Value
MDmesh M2 technology	Enables 1.06 Ω R_DS(on) at 600 V rating - reduces conduction loss by ~25% vs. prior-generation superjunction MOSFETs
Extremely low gate charge	8 nC total gate charge - lowers driver losses and enables use of cost-effective bipolar gate drivers
Optimized C_oss profile	14 pF output capacitance with 71 pF C_oss,eq - improves light-load efficiency in resonant converters
100% avalanche tested	86 mJ single-pulse avalanche energy - eliminates need for overvoltage protection in clamp-free flyback designs
Zener-protected gate	±25 V gate-source rating with internal clamp - removes external gate Zener in isolated gate drive circuits

Applications

Industrial SMPS

AC-DC Adapters

Use Scenario: 65 W universal-input laptop adapter with active clamp flyback topology.

IC Role / Device Role / Timing Role: Main power switch operating at 75 kHz with valley-switching control.

Use Value: 50 V/ns dv/dt ruggedness prevents false triggering during high-slew-rate transitions, eliminating 30% of EMI filter components.

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
STP6N60M2	Same die, TO-220 package with non-insulated tab; R_thJC = 2.08 °C/W vs. 6.25 °C/W	Requires insulating washer for heatsink mounting; higher thermal performance but lower isolation safety	Select when board-level isolation is managed externally and thermal budget is tighter than electrical clearance
FDPF6N60NZ	600 V, 1.3 Ω max, 4.5 A; Q_g = 9.5 nC; no Zener gate protection	Lacks integrated gate Zener - mandates external 18 V TVS; higher C_oss (18 pF) increases turn-off loss	Choose only if gate drive circuit already includes robust clamping and system-level EMI filtering compensates higher C_oss

Compared with STP6N60M2, STF6N60M2 trades 4.17 °C/W higher junction-to-case thermal resistance for reinforced insulation (2.5 kV RMS), while FDPF6N60NZ offers slightly higher R_DS(on) and no gate protection - making STF6N60M2 optimal for safety-critical, space-constrained industrial adapters.

FAQ

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

The STF6N60M2 supports 2.9 A continuous drain current at T_C = 100 °C, as specified in Table 1 of DS9734 Rev 3. This derating reflects thermal limitations of the TO-220FP package, where junction temperature must remain ≤150 °C under steady-state operation.

Does STF6N60M2 require external gate protection?

No. STF6N60M2 integrates a Zener diode between gate and source, rated for ±25 V, eliminating the need for external gate clamping in standard gate driver configurations. This feature is confirmed in the "Features" section and absolute maximum ratings table of the official datasheet.

How does the TO-220FP package differ from standard TO-220 in thermal performance?

The TO-220FP package has higher thermal resistance: R_thJC = 6.25 °C/W versus 2.08 °C/W for TO-220 (STP6N60M2). However, its insulated tab provides 2.5 kV RMS isolation, enabling direct heatsink mounting without additional insulators - a trade-off favoring safety over raw thermal conductivity.

Is the body diode suitable for synchronous rectification?

No. The body diode has 274 ns reverse recovery time and 1.47 µC Q_rr, which causes significant switching loss and voltage overshoot in high-frequency synchronous rectification. It is designed for freewheeling in hard-switched topologies, not for active rectification duty.
