Product details

Overview

STL3N10F7 from STMicroelectronics is an N-channel enhancement-mode Power MOSFET with 100 V V_DS, 0.062 Ω typ. R_DS(on) at V_GS = 10 V and 2 A, 4 A continuous drain current (T_pcb = 25 °C), and PowerFLAT™ 2x2 package. It delivers low gate charge (7.8 nC) and 100% avalanche-rated ruggedness for high-efficiency DC-DC converters and motor control switches.

For engineers reviewing the STL3N10F7 datasheet, STL3N10F7 pinout, STL3N10F7 application, or STL3N10F7 equivalent, key selection criteria include R_DS(on) vs. temperature stability, unclamped inductive switching capability, gate threshold voltage range (2.5–4.5 V), and thermal resistance to PCB (52 °C/W).

Technical Context

This device implements ST's STripFET™ VII DeepGATE™ architecture, featuring a redesigned gate structure that minimizes R_DS(on) while maintaining fast switching (t_d(on) = 6.3 ns, t_f = 4 ns) and low output capacitance (C_oss = 112 pF). Its 100% avalanche rating ensures robustness under transient overvoltage conditions in inductive loads.

The PowerFLAT™ 2x2 package enables high power density with exposed drain pad for thermal conduction to PCB. The device operates across –55 to 150 °C junction temperature and supports pulsed drain currents up to 16 A within safe operating area limits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - maximum blocking voltage for 24/48 V bus-level switching applications
R_DS(on) typ.	0.062 Ω @ V_GS = 10 V, I_D = 2 A - enables <125 mW conduction loss at 4 A
Q_g	7.8 nC - reduces gate drive power and allows use with low-current drivers
I_D cont.	4 A @ T_pcb = 25 °C - suitable for compact load switches with FR-4 1 in² copper area
R_thj-pcb	52 °C/W - defines thermal rise per watt dissipated into PCB without heatsink
V_GS(th)	2.5–4.5 V - compatible with 3.3 V and 5 V logic-level gate drive
C_iss	408 pF - impacts Miller effect and turn-on speed in high-frequency PWM

Pinout & Package

STL3N10F7 is housed in a surface-mount PowerFLAT™ 2x2 package with exposed drain pad on bottom side for thermal management. The package has six terminals, three of which are internally connected to drain.

Pin/Terminal	Circuit Role	Design Meaning
1 (D)	Drain	Primary high-side switching node; electrically tied to exposed pad
2 (D)	Drain	Parallel drain connection to reduce package inductance and improve current sharing
3 (G)	Gate	Control input; low Q_g enables fast, low-loss switching
4 (S)	Source	Reference node for gate drive and current sensing; connects to PCB ground plane
5 (D)	Drain	Third parallel drain terminal for enhanced thermal and electrical performance
6 (D)	Drain	Fourth drain connection-confirms full drain tie-out design for low R_DS(on) optimization

Key Features

Feature	Design Value
STripFET™ VII DeepGATE™ architecture	Reduces R_DS(on) by ~15% vs. prior STripFET VI while preserving gate oxide reliability
100% avalanche rated	Guarantees operation under unclamped inductive switching stress up to E_AS = 100 mJ (tested per JEDEC JESD24-11)
Low Q_gd/Q_g ratio	0.22 (1.7/7.8 nC) - suppresses Miller-induced shoot-through in half-bridge configurations
Enhanced body diode recovery	t_rr = 30 ns, Q_rr = 24 nC at T_j = 150 °C - minimizes switching loss in synchronous rectification

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon BSC014N04LS	R_DS(on) = 0.0014 Ω @ 4.5 V (lower), but V_DS = 40 V only	Not suitable for 100 V bus applications; limited to ≤48 V systems	Select only when lower voltage rating and higher current density are acceptable trade-offs
ON Semiconductor NTMFS4C09NT1G	R_DS(on) = 0.009 Ω @ 4.5 V, V_DS = 100 V, but Q_g = 12.5 nC (higher)	Higher gate charge increases driver loss and EMI in high-frequency SMPS	Prefer when ultra-low R_DS(on) dominates over switching efficiency

Compared with BSC014N04LS and NTMFS4C09NT1G, STL3N10F7 offers optimal balance of 100 V rating, 0.062 Ω R_DS(on), and 7.8 nC Q_g for space-constrained 24–48 V systems where thermal and gate-drive efficiency are jointly critical.

FAQ

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

The STL3N10F7 supports 2.5 A continuous drain current when mounted on an FR-4 PCB at 100 °C ambient (T_pcb = 100 °C), as specified in Table 2 of the datasheet. This derating reflects thermal limits imposed by the 52 °C/W R_thj-pcb and 150 °C max junction temperature.

Does STL3N10F7 require a gate resistor for reliable switching?

A gate resistor (e.g., 4.7 Ω) is recommended to dampen ringing and control dV/dt during switching, especially in half-bridge configurations. The device's low Q_g (7.8 nC) allows fast turn-on with minimal drive strength, but external resistance prevents oscillation caused by gate loop inductance and C_iss.

Can STL3N10F7 be used in linear mode (as a pass transistor)?

No - STL3N10F7 is not characterized or guaranteed for linear (saturation) operation. Its Safe Operating Area (SOA) curve (Figure 2) shows pulse-limited operation only; sustained linear use risks thermal runaway due to positive temperature coefficient of R_DS(on) and lack of SOA derating data beyond 10 ms pulses.

Is the PowerFLAT™ 2x2 package RoHS and REACH compliant?

Yes - STL3N10F7 is offered in ECOPACK®-compliant PowerFLAT™ 2x2 packaging, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full compliance documentation, including material declarations and substance thresholds, is available on ST's official website under ECOPACK® grade definitions.
