Product details

Overview

STL58N3LLH5 from STMicroelectronics is an automotive-grade N-channel Power MOSFET using STripFET™ H5 technology in a PowerFLAT™ 5x6 wettable flank package. It delivers 30 V V_DS, 0.0076 Ω typ. R_DS(on) at V_GS = 10 V, and 56 A continuous drain current at T_C = 25 °C, optimized for high-efficiency switching in engine control units and battery management systems.

For engineers reviewing the STL58N3LLH5 datasheet, STL58N3LLH5 pinout, STL58N3LLH5 application, or STL58N3LLH5 equivalent, key selection criteria include its AEC-Q101 qualification, low gate charge (6.5 nC typ.), high avalanche energy rating (150 mJ), and thermal resistance of 2 °C/W junction-to-case - critical for under-hood power switching reliability.

Technical Context

This MOSFET employs ST's STripFET™ H5 process to minimize conduction and switching losses simultaneously. Its 0.009 Ω max R_DS(on) at V_GS = 10 V and low C_iss (950 pF typ.) enable fast, efficient switching in 12 V automotive systems with minimal gate drive power demand.

The PowerFLAT™ 5x6 WF package features exposed source pads on all four sides for enhanced thermal dissipation and solder-joint inspection via automated optical inspection (AOI). Its 2 °C/W R_thj-case supports high-current operation without heatsinks in space-constrained ECUs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum drain-source blocking voltage compatible with 12 V automotive battery systems including load dump transients.
R_DS(on) typ.	0.0076 Ω at V_GS = 10 V - Enables <1.5 W conduction loss at 56 A, reducing thermal stress in high-current switching nodes.
I_D cont.	56 A at T_C = 25 °C - Supports high-power solenoid, fuel pump, and fan motor drivers without parallel devices.
E_AS	150 mJ - Robust unclamped inductive switching capability essential for relay and motor coil driving without snubbers.
Q_g typ.	6.5 nC - Low gate charge reduces driver IC power consumption and enables faster turn-on/turn-off transitions.
R_thj-case	2 °C/W - Allows direct mounting to PCB copper planes or small heatsinks for thermal management in compact modules.
V_GS(th)	1–2.5 V - Ensures reliable enhancement-mode turn-on with standard 3.3 V or 5 V logic-level microcontrollers.

Pinout & Package

STL58N3LLH5 uses the PowerFLAT™ 5x6 WF package - a surface-mount, wettable flank leadless package with exposed source terminals on all four edges for thermal and solder-joint inspection. Pin 1 is marked by a notch on the top-side silkscreen.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Power output terminal connected internally to the MOSFET die backside	Mounted directly to PCB copper pour for low-inductance, high-current path and thermal conduction to board.
Source (S)	Return path for load current; tied to internal substrate	Exposed on all four package edges - enables AOI verification and improves solder joint reliability in reflow.
Gate (G)	Control input for channel conduction	Single pad on top edge; requires <2.5 Ω gate series resistance to damp ringing during fast switching.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive under-hood use across –55 °C to +175 °C junction temperature range.
Wettable flank package	Enables automated optical inspection of solder fillets - critical for zero-defect manufacturing in safety-critical ECUs.
High avalanche ruggedness	150 mJ single-pulse E_AS allows safe operation during inductive load turn-off without external clamping diodes.
Low gate drive power loss	6.5 nC Q_g and 2.5 Ω R_g reduce driver power dissipation and simplify gate driver selection.
Optimized FoM (R_DS(on) × Q_g)	~0.048 Ω·nC - Among best-in-class for 30 V automotive MOSFETs, balancing conduction and switching efficiency.

Applications

Engine Control Unit (ECU) Solenoid Driver

12 V Battery Disconnect Switch

Use Scenario: Driving high-current fuel injector or turbocharger wastegate solenoids in gasoline/diesel engines.

IC Role / Device Role / Timing Role: High-side or low-side power switch controlling 10–40 A inductive loads with PWM frequencies up to 20 kHz.

Use Value: Low R_DS(on) minimizes I²R heating during extended duty cycles; high E_AS withstands back-EMF without snubber circuits.

Use Scenario: Isolating starter battery from auxiliary loads (e.g., infotainment, ADAS sensors) during cranking or fault conditions.

IC Role / Device Role / Timing Role: Bidirectional load switch enabling controlled power-up/down sequencing and reverse polarity protection.

Use Value: 30 V rating covers ISO 7637-2 pulse 5a (load dump); wettable flanks ensure solder joint integrity over 10,000 thermal cycles.

Electric Power Steering (EPS) Motor Phase Switch

Automotive HVAC Blower Motor Controller

Use Scenario: Half-bridge phase leg in 12 V EPS motor inverters requiring robust short-circuit tolerance.

IC Role / Device Role / Timing Role: Low-side switching element in three-phase inverter with desaturation detection and cycle-by-cycle current limiting.

Use Value: 224 A pulsed ID_M supports peak torque demands; 2 °C/W R_thj-case enables direct PCB thermal coupling to copper ground plane.

Use Scenario: PWM-controlled blower motor driver in climate control systems with variable speed and soft-start requirements.

IC Role / Device Role / Timing Role: High-efficiency, low-noise power stage operating at 1–20 kHz PWM with integrated freewheeling diode conduction.

Use Value: 1.1 V V_SD forward drop at 15 A reduces heat generation in freewheeling mode; low C_oss suppresses EMI during switching transitions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 30 V automotive power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon BSC014N03LS	R_DS(on) = 1.4 mΩ @ 10 V (lower), but Q_g = 12.5 nC (higher); PowerPAK® SO-8 package lacks wettable flanks.	Better conduction efficiency but higher gate drive loss; unsuitable for AOI-based automotive production lines.	Select when lowest R_DS(on) dominates and AOI is not required; verify thermal interface design for SO-8 footprint.
ON Semiconductor NTMFS5C428NT1G	R_DS(on) = 0.0042 Ω @ 10 V (lower), Q_g = 10.5 nC; PowerTrench® 5x6 package has wettable flanks but no AEC-Q101 certification.	Higher performance in lab environments; not approved for production automotive applications per OEM requirements.	Acceptable for non-safety-critical prototypes or commercial vehicles; reject for Tier 1 ECU designs requiring AEC-Q101 compliance.

Compared with BSC014N03LS and NTMFS5C428NT1G, STL58N3LLH5 uniquely balances AEC-Q101 qualification, wettable flank manufacturability, and FoM (0.048 Ω·nC) - making it the only choice for volume production of certified automotive power switches where reliability, inspectability, and thermal performance are jointly constrained.

FAQ

Is STL58N3LLH5 suitable for high-frequency PWM applications above 100 kHz?

No - its 950 pF C_iss and 27 pF Crss values make it optimized for 1–50 kHz automotive switching (e.g., solenoids, motors), not MHz-range SMPS. At >100 kHz, switching losses rise significantly due to gate charge and capacitance limitations. For high-frequency DC-DC converters, consider ST's MDmesh™ series instead.

Can STL58N3LLH5 be used in a high-side configuration with 12 V gate drive?

Yes - its V_GS rating of +22 V allows safe operation with 12 V gate drive, and its 1–2.5 V V_GS(th) ensures full enhancement. However, a dedicated high-side driver (e.g., ST's L9369) is required to provide floating gate bias; direct microcontroller connection is unsafe due to level-shifting and shoot-through risks.

What is the maximum PCB copper area needed to maintain T_J < 150 °C at 45 A continuous current?

With R_thj-pcb = 31.3 °C/W and P_D ≈ I² × R_DS(on) = 45² × 0.009 = 18.2 W, ΔT = 18.2 × 31.3 ≈ 570 °C - far exceeding safe limits. Therefore, PCB-only cooling is insufficient. The device must be mounted to a heatsink or large internal copper plane with thermal vias; junction-to-case path (2 °C/W) is the intended thermal route.

Does the STL58N3LLH5 integrate a body diode, and what are its recovery characteristics?

Yes - it includes an intrinsic source-drain body diode with 1.1 V forward voltage at 15 A and 20–36 ns reverse recovery time (t_rr) at 150 °C. This enables freewheeling in half-bridge configurations, but its Q_rr of 10–18 nC necessitates careful layout to minimize voltage overshoot during commutation in inductive loads.
