Product details

Overview

STL260N4F7 from STMicroelectronics is an N-channel Power MOSFET using STripFET F7 trench-gate technology, rated for 40 V V_DS, 0.9 mΩ typ. R_DS(on) at V_GS = 10 V, and 120 A continuous drain current at T_C = 25 °C. It delivers high avalanche ruggedness and low Crss/Ciss ratio for EMI immunity in high-efficiency DC-DC power stages.

For engineers reviewing the STL260N4F7 datasheet, STL260N4F7 pinout, STL260N4F7 application, or STL260N4F7 equivalent, key selection criteria include its 1.1 mΩ max. R_DS(on), 72 nC total gate charge, 5000 pF input capacitance, and PowerFLAT™ 5x6 package thermal resistance of 0.8 °C/W junction-to-case.

Technical Context

This MOSFET employs an enhanced trench gate structure that simultaneously minimizes on-resistance and internal capacitances-achieving 0.9 mΩ R_DS(on) and 145 pF Crss-enabling fast switching with reduced switching losses. Its low Crss/Ciss ratio (2.9%) improves EMI performance in hard-switched topologies.

The device supports high-current pulsed operation (480 A IDM) and features robust unclamped inductive switching capability, validated by SOA curves up to 10 ms pulses at T_j ≤ 175 °C. Thermal design leverages a 0.8 °C/W R_thj-case and optimized PCB layout via PowerFLAT™ 5x6 exposed drain pad.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage for 12 V/24 V automotive and industrial DC bus applications
R_DS(on) max	1.1 mΩ - Enables <1.2 W conduction loss at 100 A, critical for high-current synchronous rectification
I_D cont @ T_C=25°C	120 A - Sustained current handling with case-mounted heatsinking, supporting >3 kW power stages
Q_g	72 nC - Gate drive energy requirement defining driver sizing and switching speed in 100–500 kHz converters
C_iss	5000 pF - Input capacitance influencing gate drive loop stability and Miller effect during turn-on
V_GS(th)	2–4 V - Threshold range enabling reliable enhancement-mode operation with standard 3.3 V or 5 V logic-level gate drivers
T_j max	175 °C - Junction temperature limit supporting operation in sealed enclosures or high-ambient environments

Pinout & Package

STL260N4F7 uses the PowerFLAT™ 5x6 type C package-a surface-mount, thermally enhanced leadless package with an exposed drain pad on the bottom side for direct PCB thermal coupling. The top-side marking "260N4F7" identifies the device; pin 1 is indicated by a notch or dot per Figure 21 in DS11198 Rev 5.

Pin/Terminal	Circuit Role	Design Meaning
D (Pins 5,6,7,8)	Drain	Exposed copper pad connecting all four drain terminals-primary thermal path and high-current output node
G (Pin 4)	Gate	Single gate input terminal; requires low-inductance routing to minimize ringing and ensure clean turn-on/turn-off
S (Pins 1,2,3)	Source	Three-source terminals forming low-inductance return path; critical for minimizing source inductance in high-di/dt switching

Key Features

Feature	Design Value
Ultra-low R_DS(on)	0.9 mΩ typ. at V_GS = 10 V enables <1.2 W conduction loss at 100 A, reducing thermal burden in compact power modules
Low Crss/Ciss ratio	2.9% (145 pF / 5000 pF) suppresses Miller-induced false turn-on and improves EMI margin in high-frequency SMPS
High avalanche ruggedness	Rated for unclamped inductive switching (UIS) with guaranteed energy absorption-supports robust operation in motor drives and solenoid control
Enhanced FoM (R_DS(on) × Q_g)	79.2 mΩ·nC - Superior figure of merit vs. legacy F6/F5 devices, directly improving efficiency in 100–300 kHz buck converters
PowerFLAT™ 5x6 thermal performance	0.8 °C/W R_thj-case allows >150 W dissipation with minimal heatsink, enabling board-level thermal management without discrete coolers

Applications

Server VRM High-Side Switch

Use Scenario: 48 V BLDC motor inverter leg operating at 20 kHz PWM with peak phase current of 110 A.

IC Role / Device Role / Timing Role: High-side N-channel MOSFET switching node, synchronized with complementary low-side device.

Use Value: 0.9 mΩ R_DS(on) limits conduction loss to 1.1 W at 110 A, while 72 nC Q_g enables clean 50 ns turn-on with 2 A gate driver.

Use Scenario: 12 V input → 0.8 V/200 A output VRM in AI accelerator server, using multiphase buck topology.

IC Role / Device Role / Timing Role: High-current high-side switch in 300–500 kHz synchronous buck stage.

Use Value: Low Crss/Ciss ratio prevents shoot-through risk during dead-time; 0.8 °C/W R_thj-case sustains 175 °C T_j under full load with 2 oz Cu PCB cooling.

Automotive DC-DC Converter

Industrial UPS Output Stage

Use Scenario: 12 V to 48 V bidirectional DC-DC converter in 48 V mild-hybrid vehicle, operating at 150 kHz.

IC Role / Device Role / Timing Role: Primary-side synchronous rectifier in phase-shifted full-bridge configuration.

IC Role / Device Role / Timing Role: Low-loss switching element in H-bridge output stage driving transformer-coupled AC output.

Use Value: High avalanche energy rating ensures survivability during output short-circuit events; 55 ns t_rr minimizes reverse recovery loss in hard-commutated designs.

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 IPP023N04N	R_DS(on) = 0.95 mΩ (typ), Q_g = 82 nC, C_iss = 5200 pF - higher gate charge increases driver loss and slows switching	Same PowerSO-8 footprint but lower thermal resistance (0.7 °C/W); better for case-limited thermal designs	Select when board space permits larger package and gate drive can support +14% Q_g; avoid if EMI sensitivity is high due to higher Crss
Vishay SiR626DP	R_DS(on) = 1.05 mΩ (max), Q_g = 65 nC, Crss = 120 pF - lower gate charge but slightly higher on-resistance	PowerPAK® 5x6 package with identical footprint; 0.85 °C/W R_thj-case - near-equivalent thermal performance	Prefer for ultra-fast switching where 7 nC lower Q_g reduces turn-on loss; verify 1.05 mΩ R_DS(on) meets system conduction loss budget

Compared with STL260N4F7, IPP023N04N trades faster thermal response for higher switching loss, while SiR626DP offers lower gate drive demand at marginally higher conduction loss-making STL260N4F7 optimal for balanced high-current, high-frequency efficiency-critical designs.

FAQ

What is the maximum continuous drain current for STL260N4F7 at 100 °C case temperature?

The STL260N4F7 maintains 120 A continuous drain current rating even at T_C = 100 °C, as specified in Table 1 of DS11198 Rev 5. This reflects its robust thermal design and low R_DS(on), enabling sustained high-current operation without derating in well-heatsinked applications.

Does STL260N4F7 require a gate resistor for safe operation?

Yes-ST recommends a gate resistor (e.g., 4.7 Ω as used in switching time tests) to control dV/dt and di/dt during turn-on/turn-off. Without it, the 72 nC gate charge and low Crss can cause oscillation or overshoot, especially with high-speed gate drivers and parasitic PCB inductance.

Can STL260N4F7 be used in synchronous rectification without external Schottky diodes?

Yes-the integrated body diode has 1.2 V forward voltage at 48 A and 55 ns reverse recovery time (t_rr), making it suitable for synchronous rectification in medium-frequency (<300 kHz) buck or LLC converters where body diode conduction is brief and controlled.

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

Yes-ST certifies the STL260N4F7 PowerFLAT™ 5x6 package as ECOPACK2 compliant, meeting RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21, with lead-free matte tin terminations and no antimony or brominated flame retardants.
