Product details

Overview

STL76DN4LF7AG from STMicroelectronics is an automotive-grade dual N-channel 40 V Power MOSFET in PowerFLAT™ 5x6 double-island package, featuring 5 mΩ typ. R_DS(on) at V_GS = 10 V, 40 A continuous drain current, and AEC-Q101 qualification. It delivers high-efficiency switching in motor control and power conversion stages of 12 V/24 V automotive systems.

For engineers reviewing the STL76DN4LF7AG datasheet, STL76DN4LF7AG pinout, STL76DN4LF7AG application, or STL76DN4LF7AG equivalent, key selection criteria include low R_DS(on), wettable flank package for automated optical inspection, high avalanche ruggedness, Crss/Ciss ratio for EMI immunity, and thermal resistance junction-to-case of 2.1 °C/W.

Technical Context

This device integrates two independent N-channel STripFET™ F7 trench-gate MOSFETs in a single PowerFLAT™ 5x6 double-island package, enabling half-bridge or dual-switch topologies without discrete layout coupling. Its low Crss (28 pF) relative to Ciss (956 pF) suppresses Miller-induced turn-on during high-dV/dt switching.

The silicon supports 79 A peak current capability at 25 °C-exceeding the 40 A package-limited rating-while maintaining 175 °C max junction temperature and unclamped inductive switching robustness per AEC-Q101 stress testing.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage for 12 V/24 V automotive battery rail applications
R_DS(on) typ.	5 mΩ @ V_GS = 10 V - Enables <1 W conduction loss at 20 A, reducing heatsink requirements
I_D cont.	40 A @ T_C = 25 °C - Package-limited continuous current for sustained motor drive or DC-DC output stage
Q_g	17 nC - Low gate charge enables fast switching with moderate gate driver strength (e.g., 1–2 A peak)
R_thj-case	2.1 °C/W - Enables direct thermal coupling to PCB copper or heatsink for high-power density layouts
C_rss/C_iss	28/956 pF - Low reverse transfer capacitance improves noise immunity in high-side switching
t_r/t_f	4.3 ns / 10 ns - Sub-10 ns switching transitions support >500 kHz PWM in compact converters

Pinout & Package

STL76DN4LF7AG uses the PowerFLAT™ 5x6 double-island WF type C package-a surface-mount, wettable flank, thermally enhanced leadless package with two isolated source-drain islands. The package exposes both drain pads on the bottom for optimal thermal path and solder joint inspection.

Pin/Terminal	Circuit Role	Design Meaning
Drain 1 (D1)	Power output terminal for Channel 1	Exposed bottom pad-must be connected to PCB ground plane or low-impedance power plane for thermal and electrical performance
Drain 2 (D2)	Power output terminal for Channel 2	Second exposed bottom pad-electrically isolated from D1; enables dual-channel routing without shared thermal path
Source 1 (S1)	Return path for Channel 1	Top-side pin; connects to low-side switch node or current-sense resistor in half-bridge configuration
Gate 1 (G1)	Control input for Channel 1	Low-capacitance input (C_iss = 956 pF); requires Kelvin connection for high-speed gate driving to minimize ringing
Source 2 (S2)	Return path for Channel 2	Top-side pin; independently routed to avoid cross-talk between channels in synchronous rectification
Gate 2 (G2)	Control input for Channel 2	Electrically isolated from G1; supports independent timing control for phase-shifted or interleaved topologies

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive underhood environments including temperature cycling, HTRB, and UIS stress per Rev G standard
Wettable flank package	Vertical side-wall plating enables automated optical inspection (AOI) of solder fillets-critical for zero-defect automotive manufacturing
Low Crss/Ciss ratio	28/956 pF = 0.029 - Reduces susceptibility to false turn-on during high dV/dt commutation in motor drives
High avalanche ruggedness	Rated for unclamped inductive switching (UIS) up to 100% rated V_DS × I_D - eliminates need for external snubbers in relay replacement
Enhanced FoM (R_DS(on) × Q_g)	5 mΩ × 17 nC = 85 mΩ·nC - industry-leading figure of merit for 40 V class, balancing conduction and switching loss

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual N-channel 40 V automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon BSC028N06NS3	60 V V_DS, 2.8 mΩ R_DS(on), PG-TSDSON-8 package (single-channel), no wettable flanks	Higher voltage margin but lacks dual-channel integration and AOI-compatible package	Select when system requires 60 V rating or discrete channel optimization; not drop-in for dual-channel footprint
ON Semiconductor NTMFS4C08NT1G	40 V V_DS, 5.2 mΩ R_DS(on), SO-8FL package, AEC-Q101 qualified, no double-island layout	Single-channel, smaller thermal footprint, higher R_thj-pcb (50 °C/W vs 32 °C/W)	Prefer for space-constrained single-switch nodes where dual-channel integration is unnecessary

Compared with BSC028N06NS3 and NTMFS4C08NT1G, STL76DN4LF7AG uniquely combines dual-channel integration, wettable flank AOI support, and 2.1 °C/W junction-to-case thermal resistance-making it optimal for high-reliability, high-power-density automotive half-bridge designs requiring production traceability.

FAQ

What is the maximum allowable gate-source voltage for STL76DN4LF7AG?

The absolute maximum V_GS is ±20 V per the datasheet's Table 2. Operation beyond this risks permanent gate oxide damage. For reliable 12 V system designs, a 12 V gate drive with clamping (e.g., Zener diode to GND) is recommended to maintain margin against transients.

Does STL76DN4LF7AG support synchronous rectification in buck converters?

Yes-its dual N-channel structure, low 5 mΩ R_DS(on), and fast 4.3 ns rise time make it suitable for synchronous rectification in 48 V–12 V buck converters. Independent gate control (G1/G2) enables precise dead-time management to prevent shoot-through.

How does the PowerFLAT™ 5x6 double-island package improve thermal performance over standard SO-8?

The double-island design separates Drain 1 and Drain 2 onto distinct bottom-side thermal pads, allowing independent thermal vias and copper pours. This reduces mutual heating and achieves 2.1 °C/W R_thj-case-over 2× better than typical SO-8 MOSFETs (~5–6 °C/W)-and supports 71 W total dissipation at T_C = 25 °C.

Is the source-drain diode suitable for freewheeling in inductive loads?

Yes-the integrated body diode has 1.3 V forward voltage at 40 A and 27 ns reverse recovery time (t_rr). Its 19.5 nC Q_rr and 1.4 A I_RRM support efficient freewheeling in 12 V automotive inductive loads like solenoids and relays without external diodes.
