Product details

Overview

DMN2041L-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT23 package, rated for 20 V V_DSS, 6.4 A continuous drain current at 25°C, and 20 mΩ R_DS(ON) at V_GS = 4.5 V. It features low gate threshold (0.5–1.2 V), fast switching (t_D(ON) = 4.69 ns), and AEC-Q101 qualification-used in compact DC-DC load switches and automotive LED drivers.

For engineers reviewing the DMN2041L-7 datasheet, DMN2041L-7 pinout, DMN2041L-7 application, or DMN2041L-7 equivalent, key selection criteria include its 20 V rating, sub-1 V gate threshold enabling 1.8 V logic drive, low 550 pF C_iss, SOT23 thermal resistance of 161 °C/W, and AEC-Q101 reliability for automotive subsystems.

Technical Context

This discrete power MOSFET operates as a low-voltage, high-efficiency single-ended switch with enhancement-mode gate control. Its 0.5–1.2 V V_GS(TH) range supports direct interface with 1.8 V and 3.3 V microcontrollers, while 20 mΩ R_DS(ON) at 4.5 V ensures <100 mW conduction loss at 6 A.

The device uses planar silicon technology with optimized gate oxide and channel doping to achieve low input capacitance (550 pF C_iss) and fast turn-on (4.69 ns delay) without sacrificing leakage performance-IDSS ≤ 1.0 µA at 20 V and IGSS ≤ ±100 nA at ±12 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	20 V - Maximum blocking voltage for 12 V automotive and 5 V/3.3 V logic-supplied systems
R_DS(ON) @ 4.5 V	20 mΩ - Enables ≤720 mW I²R loss at 6 A, suitable for thermally constrained PCB layouts
V_GS(TH)	0.5–1.2 V - Guarantees reliable turn-on with 1.8 V GPIO, eliminating level-shifter requirement
C_iss	550 pF - Reduces gate drive power and enables >1 MHz switching in buck converter high-side use
t_D(ON)	4.69 ns - Supports precise timing control in synchronous rectification and PWM dimming circuits
Q_g @ 4.5 V	7.2 nC - Low gate charge minimizes driver IC stress and allows use with low-current MCU pins
T_J Range	−55 to +150 °C - Validated operation across extended automotive ambient conditions

Pinout & Package

SOT23-3 surface-mount plastic package with matte tin–annealed copper leadframe; moisture sensitivity level 1 per J-STD-020; weight ≈ 0.008 g.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Current return path for drain-to-source conduction	Internally connected to substrate; requires low-impedance ground plane for thermal and EMI control
2 (Gate)	Control electrode for channel formation	High-impedance input; sensitive to ESD-requires series resistor (≤10 Ω) and local decoupling
3 (Drain)	Main current output terminal	Connected to load/high-side rail; layout must minimize trace inductance to suppress voltage spikes

Key Features

Feature	Design Value
Low R_DS(ON) at 2.5 V drive	26 mΩ - Enables functional switching even under brown-out or battery sag conditions down to 2.5 V supply
AEC-Q101 qualified	Stress-tested for automotive temperature cycling, HTRB, and ESD-validates suitability for under-hood modules
Green, halogen-free construction	<900 ppm Br/Cl, <1000 ppm Sb - Meets EU RoHS 3 and automotive OEM material compliance requirements
Low C_oss and C_rss	88 pF / 81 pF - Minimizes Miller effect, improving noise immunity and reducing shoot-through risk in half-bridge designs

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel low-voltage MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2040U-7	Same SOT23 package, but 1.0 V higher V_GS(TH) (1.0–2.0 V), 28 mΩ R_DS(ON) @ 4.5 V	Requires ≥2.5 V gate drive; less suitable for 1.8 V logic interfaces	Select when higher gate threshold improves noise immunity in noisy industrial environments
AO3400	20 V rating, 28 mΩ R_DS(ON) @ 4.5 V, but not AEC-Q101 qualified; C_iss = 750 pF	Lacks automotive reliability validation; higher gate capacitance increases drive power	Acceptable for cost-sensitive consumer applications where AEC-Q101 is not mandated

Compared with DMN2040U-7 and AO3400, the DMN2041L-7 delivers lower gate threshold and on-resistance for tighter logic-level compatibility and reduced conduction loss-critical in thermally constrained, automotive-grade power gating.

FAQ

Is DMN2041L-7 suitable for 1.8 V microcontroller gate drive?

Yes. Its guaranteed gate threshold voltage range of 0.5–1.2 V ensures full enhancement with 1.8 V logic outputs, verified by transfer characteristics up to 150 °C. No level shifter is required, and typical R_DS(ON) remains ≤26 mΩ at V_GS = 2.5 V and I_D = 5.2 A.

What is the maximum continuous current at 70°C ambient?

The datasheet specifies 4.5 A continuous drain current at T_A = +70°C on FR-4 PCB with minimum recommended pad layout. This derating accounts for thermal resistance of 161 °C/W and junction-to-ambient heating-actual current depends on board copper area and airflow.

Does DMN2041L-7 have integrated ESD protection?

No. The device has no built-in ESD protection diodes. Its gate oxide is rated for ±12 V V_GS, but external protection (e.g., TVS diode between gate and source) is recommended for handling >2 kV HBM in manufacturing or field environments.

Why is DMN2041L-7 marked "NOT RECOMMENDED FOR NEW DESIGN"?

This marking reflects Diodes Incorporated's internal product roadmap-not reliability concerns. The part remains fully qualified and in active production; however, newer alternatives like DMN2041U may offer improved specs. Legacy designs may continue using DMN2041L-7 without restriction.
