Product details

Overview

STL20NF06LAG from STMicroelectronics is an automotive-grade N-channel Power MOSFET with 60 V V_DS, 27 mΩ typ. R_DS(on) at V_GS = 10 V, 20 A continuous drain current (T_case = 25 °C), 75 W total power dissipation, and AEC-Q101 qualification. It serves as a primary switching device in isolated DC-DC converters for telecom and computing systems where low gate charge and fast switching are critical.

For engineers reviewing the STL20NF06LAG datasheet, STL20NF06LAG pinout, STL20NF06LAG application, or STL20NF06LAG equivalent, key selection criteria include its PowerFLAT™ 5x6 wettable flanks package, logic-level gate threshold (1–2.5 V), 22.5 nC total gate charge, 670 pF input capacitance, and 175 °C maximum junction temperature.

Technical Context

This MOSFET employs ST's STripFET™ II process to minimize input capacitance (C_iss = 670 pF) and gate charge (Q_g = 22.5 nC), enabling high-frequency operation in hard-switched topologies. Its low R_DS(on) of 27 mΩ at 10 V gate drive supports efficient conduction in 48 V bus and intermediate bus converter applications.

The device features a source-drain diode with 28 ns reverse recovery time (t_rr) and 31.6 nC reverse recovery charge (Q_rr), suitable for synchronous rectification and inductive load switching. Thermal resistance junction-to-case is 2.0 °C/W, enabling high-power density mounting on compact PCBs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum blocking voltage for 48 V system-level designs with margin
R_DS(on) max	40 mΩ at V_GS = 10 V - Ensures ≤0.6 W conduction loss at 4 A continuous current
Q_g	22.5 nC - Enables fast turn-on with low gate driver power demand
C_iss	670 pF - Reduces Miller effect and improves switching stability in high-dV/dt environments
T_j max	175 °C - Supports operation in under-hood automotive environments and sealed enclosures
I_D (pulsed)	80 A - Handles short-duration surge currents in motor drive or hot-swap circuits
t_rr	28 ns - Limits switching losses during diode commutation in synchronous buck stages

Pinout & Package

STL20NF06LAG is housed in a PowerFLAT™ 5x6 package with wettable flanks (WF), optimized for automated optical inspection (AOI) and high thermal performance via exposed drain pad soldering to PCB copper.

Pin/Terminal	Circuit Role	Design Meaning
D (Pins 5, 6, 7, 8)	Drain	High-current output node; electrically connected to exposed metal pad for thermal and electrical conduction
G (Pin 4)	Gate	Control terminal requiring <22.5 nC charge for full enhancement; logic-level compatible (V_GS(th) = 1–2.5 V)
S (Pins 1, 2, 3)	Source	Reference node for gate drive and current sensing; tied to PCB ground plane for low-inductance return path

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain and body electronics per stress test requirements
PowerFLAT™ 5x6 WF	Enables AOI-compatible solder joint inspection and 2.0 °C/W junction-to-case thermal resistance
Low Q_g/C_iss ratio	22.5 nC / 670 pF = 33.6 V - Improves figure-of-merit for high-frequency switching efficiency
Logic-level V_GS(th)	1–2.5 V threshold enables direct drive from 3.3 V or 5 V microcontrollers without level-shifting
175 °C T_j rating	Supports sustained operation in high-ambient environments such as engine control units and LED drivers

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
IPB034N06L3	R_DS(on) = 3.4 mΩ @ 10 V (lower), Q_g = 32 nC (higher), PowerPAK® SO-8 package	Higher current density but larger footprint; not wettable-flank AOI-ready	Preferred for ultra-low R_DS(on) needs where board space allows SO-8 mounting
IRLML6344TRPBF	R_DS(on) = 45 mΩ @ 4.5 V, SOT-23 package, 4.2 A I_D rating	Lower current/power capability; suited for signal-level switching, not power conversion	Only viable for low-power auxiliary loads (<1 A), not primary DC-DC switching

Compared with IPB034N06L3 and IRLML6344TRPBF, STL20NF06LAG uniquely balances 20 A current handling, PowerFLAT™ 5x6 wettable flanks for production reliability, and 22.5 nC gate charge-making it optimal for automotive and telecom power modules where thermal density and AOI compatibility are mandatory.

FAQ

What is the maximum safe operating temperature for STL20NF06LAG?

The absolute maximum junction temperature is 175 °C, and the storage temperature range is –55 to +175 °C. Operation at T_j = 175 °C requires derating of drain current and power dissipation per the Safe Operating Area (SOA) curves in Figure 2 of the datasheet, with thermal design ensuring R_thj-pcb ≤ 31.3 °C/W on a 1-inch² FR-4 board.

Does STL20NF06LAG support gate drive from a 3.3 V microcontroller?

Yes. With a gate threshold voltage V_GS(th) of 1–2.5 V (typ. 1.8 V), STL20NF06LAG fully enhances at 3.3 V gate drive, delivering R_DS(on) ≤ 50 mΩ at V_GS = 5 V and ID = 4 A. For optimal performance, use ≥4.5 V drive to achieve sub-40 mΩ on-resistance.

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

Yes. STL20NF06LAG is offered in ECOPACK®-compliant packaging, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The PowerFLAT™ 5x6 WF type R package uses lead-free matte tin plating and halogen-free molding compound per ST's published ECOPACK® grade documentation.

Can STL20NF06LAG be used in synchronous rectification configurations?

Yes. Its source-drain diode has t_rr = 28 ns and Q_rr = 31.6 nC, enabling use as a freewheeling or synchronous rectifier in buck, flyback, and LLC topologies. However, dedicated synchronous rectifier MOSFETs offer lower Q_rr; this part is best applied where primary switching and diode recovery coexist in shared layout constraints.
