Product details

Overview

STL90N10F7 from STMicroelectronics is an N-channel Power MOSFET in PowerFLAT 5x6 package, designed for high-efficiency switching in DC-DC converters and motor drives. It delivers 100 V V_DS, 7 mΩ typ. R_DS(on) at V_GS = 10 V, 70 A continuous drain current at T_C = 25 °C, and 300 mJ single-pulse avalanche energy - enabling robust operation in automotive body control modules and industrial power supplies.

For engineers reviewing the STL90N10F7 datasheet, STL90N10F7 pinout, STL90N10F7 application, or STL90N10F7 equivalent, key selection criteria include its low Cr_ss/C_iss ratio for EMI immunity, high avalanche ruggedness, thermal resistance junction-to-case of 1.5 °C/W, and compatibility with high-frequency synchronous rectification topologies.

Technical Context

This device employs STripFET F7 trench-gate technology to minimize R_DS(on) while reducing gate charge (Q_g = 45–60 nC) and output capacitance (C_oss = 700–910 pF), supporting fast switching with reduced switching losses. Its low Cr_ss (45–58 pF) suppresses Miller-induced turn-on during hard-switching transients.

The MOSFET features a source-drain diode with V_SD = 1.1 V at I_SD = 16 A and t_rr = 70–90 ns under defined inductive conditions, making it suitable for freewheeling paths where reverse recovery behavior impacts efficiency and EMI.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - supports 48 V and 60 V bus systems with margin for voltage spikes in automotive and industrial DC-DC stages.
R_DS(on) max	8 mΩ - enables <1 W conduction loss at 35 A, critical for thermally constrained PowerFLAT 5x6 PCB layouts.
I_D continuous (T_C = 25 °C)	70 A - rated per R_thJC = 1.5 °C/W, requiring direct thermal pad connection to copper pour for full current capability.
EAS	300 mJ - withstands unclamped inductive switching events without failure, essential for relay driving and solenoid control.
C_rss/C_iss ratio	~1.5% (45/3100 pF typ.) - minimizes dv/dt-induced gate oscillation and improves noise immunity in noisy ECU environments.
t_r/t_f	32 ns / 13 ns - enables >500 kHz PWM operation with low switching loss when driven by 4.7 Ω gate resistor.
V_GS(th)	2.5–4.5 V - ensures reliable enhancement-mode turn-on with standard 3.3 V or 5 V logic-level gate drivers.

Pinout & Package

STL90N10F7 uses the PowerFLAT 5x6 (Type R SUBCON) surface-mount package with exposed drain thermal pad. Dimensions: 5.0 × 6.0 × 0.95 mm (L × W × H), with 8-pin configuration optimized for high-current routing and thermal dissipation.

Pin/Terminal	Circuit Role	Design Meaning
D (Pins 5, 6, 7, 8)	Drain terminal	Connected to high-side switch node or DC bus; electrically and thermally tied to exposed copper pad on bottom side.
G (Pin 4)	Gate terminal	Control input requiring <60 nC total charge; sensitive to ESD and layout parasitics due to low threshold voltage range.
S (Pins 1, 2, 3)	Source terminal	Return path for load current; multiple pins reduce source inductance and improve current sharing in high-di/dt applications.

Key Features

Feature	Design Value
Lowest R_DS(on) in 100 V class	7 mΩ typ. at V_GS = 10 V - reduces conduction loss by ≥25% vs. legacy 100 V MOSFETs in same footprint.
Enhanced FoM (R_DS(on) × Q_g)	~315 mΩ·nC - balances switching and conduction loss for optimal efficiency in 200–1000 kHz SMPS designs.
Low Cr_ss/C_iss ratio	1.5% typ. - suppresses false turn-on during high dv/dt commutation, eliminating need for negative gate drive in half-bridge legs.
High avalanche ruggedness	300 mJ single-pulse - sustains repetitive inductive kickback in motor gate drivers without derating or external snubbers.
PowerFLAT 5x6 thermal performance	R_thJC = 1.5 °C/W - enables 100 W power dissipation with minimal heatsink, ideal for space-constrained automotive ECUs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 100 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon IPP040N10N5	R_DS(on) = 4.0 mΩ (lower), Q_g = 62 nC (higher), TO-220FP package	Requires through-hole mounting and larger heatsink; unsuitable for ultra-thin automotive modules	Select only if board space permits TO-220 footprint and higher gate drive capability is available.
Vishay SIHF10N100D	R_DS(on) = 105 mΩ (much higher), TO-247 package, 100 V rating	Limited to <10 A continuous; used in legacy linear regulators and low-frequency inverters	Use only for cost-sensitive, low-frequency (<50 kHz), low-current replacements where thermal margin is ample.

Compared with IPP040N10N5 and SIHF10N100D, STL90N10F7 uniquely combines PowerFLAT 5x6 compactness, sub-8 mΩ R_DS(on), and 300 mJ avalanche rating - making it the only option qualified for space-constrained, high-reliability 48 V automotive switching without thermal derating.

FAQ

What is the maximum safe operating frequency for STL90N10F7 in a hard-switched buck converter?

STL90N10F7 supports up to 1 MHz switching in optimized layouts, but practical hard-switched operation is limited to 500–700 kHz due to gate charge (45–60 nC) and output capacitance (700–910 pF). At 500 kHz with 4.7 Ω gate resistor, measured t_r/t_f remains within 32/13 ns, ensuring <5% switching loss contribution at 20 A load.

Can STL90N10F7 be used in a high-side configuration with bootstrap gate driving?

Yes - STL90N10F7 is compatible with bootstrap gate drivers when V_DD ≥ 10 V and bootstrap capacitor ≥ 100 nF. Its V_GS rating of ±20 V and 2.5–4.5 V threshold allow reliable turn-on even with 12 V gate drive, but layout must minimize source inductance to avoid shoot-through during commutation.

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

Yes - STL90N10F7 is supplied in ECOPACK2-compliant PowerFLAT 5x6 packaging, meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. The device uses matte tin plating on terminals and halogen-free molding compound, certified per ST's ECOPACK documentation.

What is the recommended PCB footprint for thermal reliability?

ST recommends a minimum 25 mm² exposed copper thermal pad connected to ≥2 internal ground planes via 8–12 thermal vias (0.3 mm diameter, 0.8 mm pitch). The footprint must match Figure 19 in DS9621 Rev 8, with solder mask defined (SMD) stencil opening to ensure void-free solder joint under the drain pad.
