Product details

Overview

STL100N6LF6 from STMicroelectronics is an N-channel 60 V Power MOSFET in PowerFLAT™ 5x6 package, featuring 3.3 mΩ typ. R_DS(on) at V_GS = 10 V, 25 A continuous drain current at T_pcb = 25 °C, and high avalanche ruggedness (E_AS = 1370 mJ). It serves as a high-efficiency main switch in DC-DC converters for telecom power supplies.

For engineers reviewing the STL100N6LF6 datasheet, STL100N6LF6 pinout, STL100N6LF6 application, or STL100N6LF6 equivalent, key selection criteria include low gate charge (121 nC), thermal resistance junction-to-PCB (31.3 °C/W), avalanche energy rating, and PowerFLAT™ 5x6 footprint compatibility with high-current PCB layouts.

Technical Context

This MOSFET employs ST's 6th-generation STripFET™ VI DeepGATE™ technology with optimized gate structure to minimize R_DS(on) and gate charge simultaneously. Its internal schematic confirms single-die N-channel enhancement-mode operation with integrated body diode.

The device is characterized for both case-mounted (R_thj-case = 1.13 °C/W) and PCB-mounted (R_thj-pcb = 31.3 °C/W) thermal paths, supporting dual thermal design strategies. Avalanche testing per IEC 61881 confirms repetitive capability up to 10 A with E_AS = 1370 mJ at T_j = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum blocking voltage compatible with 48 V input systems and transient overvoltage margins.
R_DS(on) typ.	3.3 mΩ at V_GS = 10 V, I_D = 11 A - Enables <1 W conduction loss at 25 A, critical for high-efficiency 12–48 V buck converters.
Q_g	121 nC - Low total gate charge reduces drive power and enables fast switching with standard gate drivers.
E_AS	1370 mJ - High unclamped inductive switching robustness supports reliable operation in hard-switched topologies without snubbers.
I_D cont. (T_pcb)	25 A at T_pcb = 25 °C - Specifies usable current under real-world PCB thermal conditions, not ideal heatsink assumptions.
C_iss	6600 pF - Input capacitance impacts gate drive loop stability and turn-on timing in high-frequency (>500 kHz) SMPS designs.
T_j max	175 °C - Junction temperature limit enabling operation in industrial ambient environments up to 105 °C with proper layout.

Pinout & Package

STL100N6LF6 uses the PowerFLAT™ 5x6 surface-mount package (JEDEC MO-263 variant), with exposed drain pad for thermal and electrical connection. The package features 8 terminals: four parallel drain pins, one gate pin, and three parallel source pins - optimized for low-inductance, high-current routing.

Pin/Terminal	Circuit Role	Design Meaning
D (pins 5, 6, 7, 8)	Drain	High-side switching node; all four pins electrically connected to die drain and exposed copper pad for thermal dissipation.
G (pin 4)	Gate	Control terminal requiring ≤±20 V bias; low input capacitance (C_iss = 6600 pF) eases driver selection.
S (pins 1, 2, 3)	Source	Power return path; three parallel pins reduce bond-wire inductance and improve current sharing in high-di/dt applications.

Key Features

Feature	Design Value
Low gate charge	Q_g = 121 nC - Reduces gate drive losses and enables use of cost-effective 1-A peak drivers in 300–1000 kHz converters.
Very low on-resistance	R_DS(on) = 3.3 mΩ typ. - Delivers >96% efficiency at 25 A/12 V output in synchronous buck stages with minimal heatsinking.
High avalanche ruggedness	E_AS = 1370 mJ - Eliminates need for external clamping circuits in flyback or LLC resonant converter primary switches.
Optimized for PCB thermal transfer	R_thj-pcb = 31.3 °C/W - Achievable with 1 in² 2 oz Cu pad; enables compact, fanless 100–200 W power modules.

Applications

Telecom DC-DC Converters

Industrial Motor Drives

Use Scenario: Primary-side switch in isolated 48 V input / 12 V output half-bridge DC-DC converters for base station power units.

IC Role / Device Role / Timing Role: High-side power switch operating at 300–500 kHz with synchronous rectification on secondary side.

Use Value: 3.3 mΩ R_DS(on) limits conduction loss to <2.1 W at 25 A, enabling >95% full-load efficiency without forced air cooling.

Use Scenario: Half-bridge leg in 24–48 V BLDC motor controllers for automated guided vehicles (AGVs).

IC Role / Device Role / Timing Role: Low-side switching element in 3-phase inverter stage, commutated at 10–20 kHz with PWM dead-time control.

Use Value: 121 nC Q_g allows clean 100 ns rise/fall times using TC4427 drivers, minimizing switching loss during high-torque acceleration phases.

Server VRMs

LED Driver Power Stages

Use Scenario: High-current phase-leg MOSFET in multiphase buck VRM supplying CPU core voltage (0.8–1.2 V @ up to 200 A).

IC Role / Device Role / Timing Role: Synchronous rectifier in interleaved 600 kHz buck stage, driven by dedicated gate controller.

Use Value: Parallel source pins (S1–S3) and drain pads reduce parasitic inductance, suppressing voltage spikes during 500 A/μs di/dt transients.

Use Scenario: Buck converter switch in constant-current LED drivers for street lighting (36–72 V input, 3–5 A output).

IC Role / Device Role / Timing Role: Main power switch modulated at 200 kHz to regulate LED string current with ±1% accuracy.

Use Value: 1370 mJ E_AS withstands inductive kickback from long LED strings during fault shutdown, preventing catastrophic failure.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 60 V Power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon IPP040N06N	R_DS(on) = 3.7 mΩ (typ.), Q_g = 110 nC, same PowerSO-10 package footprint but different pinout (G/S/D vs D/G/S).	Lower gate charge improves switching efficiency above 1 MHz, but higher R_DS(on) increases conduction loss at >20 A.	Select when operating >800 kHz with tight gate drive power budget; verify PCB layout compatibility due to reversed pin order.
Vishay SiHL100N60E	R_DS(on) = 4.0 mΩ (typ.), Q_g = 135 nC, TO-220FP package with insulated tab (R_thj-case = 1.5 °C/W).	Higher thermal resistance requires heatsink; larger footprint limits board density but simplifies thermal management.	Select for prototyping or low-volume industrial drives where mechanical mounting and heatsink integration outweigh size constraints.

Compared with STL100N6LF6, IPP040N06N trades marginally higher conduction loss for better high-frequency switching, while SiHL100N60E sacrifices board space and layout complexity for simplified thermal design and mechanical robustness.

FAQ

What is the maximum safe operating frequency for STL100N6LF6 in a hard-switched buck converter?

Based on measured switching times (t_d(on) = 20 ns, t_f = 22 ns) and gate charge (121 nC), STL100N6LF6 supports reliable operation up to 1 MHz in well-designed buck converters with optimized gate drive and layout. Above 750 kHz, attention to PCB parasitics and gate resistor selection becomes critical to avoid shoot-through and oscillation.

Can STL100N6LF6 be used in linear mode (as a pass transistor)?

No - STL100N6LF6 is not characterized or rated for linear-mode operation. Its Safe Operating Area (SOA) curve shows limited DC capability (≤10 A at V_DS = 10 V), and the device lacks SOA derating data for extended linear use. It is intended strictly for switched-mode applications with defined duty cycle and thermal management.

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

Yes - STL100N6LF6 is manufactured in ST's ECOPACK®2-compliant PowerFLAT™ 5x6 package, meeting RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level MSL3. The package uses lead-free solderable terminations and halogen-free molding compound.

Does the body diode recovery performance support synchronous rectification?

Yes - with t_rr = 34 ns and Q_rr = 44 nC at T_j = 150 °C, the intrinsic body diode enables efficient synchronous rectification in buck and flyback topologies up to 500 kHz. However, external Schottky diodes are recommended for ultra-low forward drop where reverse recovery noise must be minimized.
