Product details

Overview

STL260N4LF7 from STMicroelectronics is an N-channel Power MOSFET using STripFET F7 trench-gate technology, rated for 40 V V_DS, 0.85 mΩ typical R_DS(on) at V_GS = 10 V, and 120 A continuous drain current at T_C = 25 °C. It delivers ultra-low conduction loss and fast switching in high-efficiency DC-DC converters and motor drive half-bridges.

For engineers reviewing the STL260N4LF7 datasheet, STL260N4LF7 pinout, STL260N4LF7 application, or STL260N4LF7 equivalent, key selection criteria include its 1.1 mΩ max R_DS(on), 170 pF Crss/Ciss ratio for EMI resilience, 42 nC total gate charge, 71 ns reverse recovery time, and PowerFLAT 5x6 thermal performance with 0.8 °C/W R_thj-case.

Technical Context

This MOSFET employs an enhanced trench gate structure that simultaneously reduces R_DS(on) and internal capacitances-C_iss = 6000 pF typ., C_oss = 1700 pF typ., Crss = 170 pF typ.-enabling high-frequency operation up to 1 MHz in synchronous buck stages.

Its low Crss/Ciss ratio (≈2.8%) minimizes Miller-induced voltage spikes during hard switching, while the integrated source-drain diode supports freewheeling in inductive loads with 1 V V_SD at 50 A and 71 ns t_rr, enabling robust unclamped inductive switching up to 480 A pulsed current.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage for 12–24 V system-level power rails
R_DS(on) max	1.1 mΩ at V_GS = 10 V, I_D = 25 A - Enables <1.2 W conduction loss at 100 A in PCB-mounted thermal design
I_D cont. (T_C = 25 °C)	120 A - Supports high-current single-phase motor drives without paralleling
Q_g	42 nC - Allows efficient gate driving with standard 1-A peak drivers at ≥500 kHz
t_r/t_f	14 ns / 23 ns - Enables fast transition through linear region, reducing switching losses by >30% vs legacy FETs
R_thj-case	0.8 °C/W - Delivers 188 W power dissipation capability with minimal heatsink requirement
V_GS(th)	1.2–2.5 V - Ensures reliable turn-on with 3.3 V logic-level gate drivers

Pinout & Package

STL260N4LF7 uses the PowerFLAT™ 5x6 type C package-a thermally optimized, surface-mount, dual-side cooling package with exposed drain pad on the bottom and 8-pin top-side layout. The package enables direct thermal coupling to PCB copper and supports high-current routing via D(5,6,7,8), G(4), S(1,2,3) terminal configuration.

Pin/Terminal	Circuit Role	Design Meaning
D (pins 5, 6, 7, 8)	Drain (common source connection)	Four parallel drain terminals tied to large exposed copper pad-optimized for low-inductance, high-current return path and thermal conduction to PCB
G (pin 4)	Gate	Single gate input with 100 nF gate-source decoupling recommended; low Q_gd/Q_gs ratio suppresses dv/dt-induced false turn-on
S (pins 1, 2, 3)	Source	Three dedicated source pins reduce source inductance and improve current sharing in high-di/dt applications like motor phase legs

Key Features

Feature	Design Value
Ultra-low R_DS(on)	0.85 mΩ typ. at V_GS = 10 V - Reduces I²R losses by >40% versus comparable 40 V FETs in 48 V telecom PSUs
Low Crss/Ciss ratio	170/6000 ≈ 2.8% - Limits Miller feedback, enabling stable 100 V/ns dv/dt operation without external gate clamping
High avalanche ruggedness	Unclamped inductive switching rated to 480 A pulsed - Eliminates need for external snubbers in BLDC gate driver designs
Enhanced thermal resistance	R_thj-pcb = 31.3 °C/W on 1 in² 2 oz Cu - Achieves 120 A operation with only 2-layer PCB thermal relief, no heatsink

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 40 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon IPP026N04L	R_DS(on) = 0.95 mΩ max, Q_g = 45 nC, Crss = 190 pF	Higher Crss increases dv/dt sensitivity; requires tighter gate loop layout	Preferred where lower R_DS(on) is critical and board layout allows strict gate routing control
ON Semiconductor NTMFS4C08NT1G	R_DS(on) = 1.25 mΩ max, Q_g = 38 nC, R_thj-case = 1.1 °C/W	Higher thermal resistance limits continuous current to 105 A at same case temp	Selected when gate drive energy budget is constrained and moderate conduction loss is acceptable

Compared with IPP026N04L and NTMFS4C08NT1G, STL260N4LF7 offers the lowest Crss/Ciss ratio for EMI-critical environments and best thermal performance per unit area-making it optimal for space-constrained, high-reliability industrial motor drives where layout margin is limited.

FAQ

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

The STL260N4LF7 supports 35 A continuous drain current when mounted on a standard FR-4 PCB at T_pcb = 100 °C, as rated by its R_thj-pcb = 31.3 °C/W thermal resistance and 175 °C maximum junction temperature. This value assumes 1 in² of 2 oz copper for thermal spreading and accounts for ambient derating in enclosed enclosures.

Does this MOSFET require a gate resistor for stability in high-speed switching?

Yes-a 4.7 Ω gate resistor is specified in the datasheet for switching time characterization (td(on), tr, td(off), tf) and ensures controlled turn-on/turn-off to prevent ringing and overshoot. Lower values may cause gate oscillation due to PCB inductance interacting with low Q_gd; higher values increase switching losses disproportionately.

Can STL260N4LF7 be used in synchronous rectification without external Schottky diodes?

Yes-the integrated source-drain diode has 1 V forward voltage at 50 A and 71 ns reverse recovery time, making it suitable for synchronous rectification in buck converters up to 300 kHz. However, for >500 kHz operation or ultra-low V_SD requirements, an external Schottky remains preferred due to its zero recovery charge.

Is the PowerFLAT 5x6 package lead-free and RoHS-compliant?

Yes-STL260N4LF7 is supplied in ECOPACK2-compliant PowerFLAT 5x6 type C packaging, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The device is halogen-free and qualifies for lead-free reflow soldering per JEDEC J-STD-020D.3 at peak temperatures up to 260 °C.
