Product details

Overview

STL6N2VH5 from STMicroelectronics is an N-channel Power MOSFET optimized for high-efficiency switching in space-constrained applications, featuring 20 V V_DS, 0.025 Ω R_DS(on) (typ. at V_GS = 4.5 V), 6 A continuous drain current, and PowerFLAT™ 2×2 package with exposed drain pad for thermal performance. It serves as a low-voltage power switch in DC-DC converters and load management circuits.

For engineers reviewing the STL6N2VH5 datasheet, STL6N2VH5 pinout, STL6N2VH5 application, or STL6N2VH5 equivalent, key selection criteria include gate threshold voltage (0.7 V typ.), ultra-low gate charge (4.6 nC), thermal resistance (52 °C/W to PCB), and 2.5 V logic-level drive compatibility in compact power stages.

Technical Context

This device implements ST's STripFET™ V process to minimize conduction and switching losses simultaneously. Its 0.025 Ω R_DS(on) at 4.5 V gate drive and 16 pF Crss enable fast, low-loss switching in high-frequency buck regulators and synchronous rectifiers.

The MOSFET integrates a robust body diode with 10 ns reverse recovery time and 24 nC Q_rr, supporting efficient inductive load switching. Its ±8 V V_GS rating and -55 to 150 °C operating junction temperature support industrial-grade reliability under transient stress.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	20 V - supports 12 V rail systems with margin against transients
R_DS(on)	0.025 Ω (typ. at V_GS = 4.5 V) - enables <150 mW conduction loss at 6 A
Q_g	4.6 nC - reduces gate drive power and enables >1 MHz switching
I_D (cont)	6 A at T_pcb = 25 °C - suitable for medium-power point-of-load stages
R_thj-pcb	52 °C/W - achieves <100 °C junction rise with 2.4 W dissipation on 1 in² FR-4
V_GS(th)	0.7 V (typ.) - ensures turn-on with 2.5 V microcontroller GPIOs
C_iss	367 pF - balances EMI control and switching speed in hard-switched topologies

Pinout & Package

Supplied in PowerFLAT™ 2×2 package (2.0 mm × 2.0 mm × 0.8 mm), with exposed drain pad for enhanced thermal conduction to PCB. Pin 1–3 and 6 are Drain; Pin 4 is Source; Pin 3 is Gate - confirmed per internal schematic and mechanical drawing Fig. 19.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 6	Drain (D)	High-current output node; connected to exposed copper pad for thermal and electrical path
4	Source (S)	Reference node for gate drive and current sensing; tied to power ground plane
3	Gate (G)	Control input; requires <4.6 nC charge for full enhancement; sensitive to ESD

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS = 2.5 V, enabling direct MCU interface without level-shifting
Ultra-low R_DS(on)	0.025 Ω typ. at 4.5 V reduces I²R loss by >30% vs. legacy 20 V MOSFETs in same footprint
Low Crss (16 pF)	Minimizes Miller-induced shoot-through risk and improves dv/dt immunity in half-bridge layouts
Optimized body diode	10 ns t_rr and 24 nC Q_rr reduce switching loss and ringing in synchronous rectification

Applications

DC-DC Buck Converter

USB Power Delivery Switch

Use Scenario: High-efficiency 5 V/3.3 V step-down regulator in portable electronics with tight thermal constraints.

IC Role / Device Role: Synchronous high-side switch handling up to 6 A peak current at 500 kHz–1 MHz.

Use Value: ±8 V V_GS rating and 20 V V_DS withstand capability eliminate need for external clamping in 12 V industrial rails.

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
DMN2020LFG-7	R_DS(on) = 0.028 Ω (V_GS = 4.5 V); Q_g = 5.2 nC; same PowerFLAT 2×2 package	Slightly higher conduction loss; identical thermal footprint	Preferred when dual sourcing required and 0.003 Ω R_DS(on) margin is acceptable
AO3400	R_DS(on) = 0.026 Ω (V_GS = 10 V); requires 4.5 V min. gate drive; SO-8 package	Larger footprint; higher R_thj-amb; no exposed drain pad	Selected only if SO-8 layout reuse is mandatory and thermal derating to 4.5 A is acceptable

Compared with DMN2020LFG-7 and AO3400, STL6N2VH5 delivers the lowest combined conduction-switching FOM (R_DS(on) × Q_g) in its class and superior thermal performance due to PowerFLAT™ 2×2's low-profile exposed drain, making it optimal for ultra-compact, high-density power designs.

FAQ

What is the maximum safe operating frequency for STL6N2VH5 in a buck converter?

Based on measured 4.8 ns t_d(on), 14.4 ns t_r, 17 ns t_d(off), and 4 ns t_f, STL6N2VH5 supports reliable operation up to 2 MHz in hard-switched buck topologies with appropriate gate drive strength (≤10 Ω series resistance) and PCB layout minimizing loop inductance.

Can STL6N2VH5 be used in a synchronous rectifier configuration?

Yes - its 10 ns reverse recovery time, 24 nC Q_rr, and low Crss (16 pF) make it suitable for synchronous rectification in 12 V–20 V secondary-side applications, provided gate timing avoids cross-conduction and the body diode is not subjected to unclamped inductive turn-off.

Is the PowerFLAT™ 2×2 package lead-free and RoHS-compliant?

Yes - STL6N2VH5 is supplied in ECOPACK®-compliant PowerFLAT™ 2×2 packaging, meeting RoHS Directive 2011/65/EU and halogen-free requirements per ST's published ECOPACK® grade definitions, with lead finish of matte tin on copper.

Does STL6N2VH5 require a gate resistor for stability?

A gate resistor (typically 2.2–10 Ω) is recommended to dampen gate oscillation caused by PCB trace inductance interacting with C_iss (367 pF) and C_rss (16 pF), especially when driven by high-speed microcontrollers or gate drivers with low output impedance.
