Product details

Overview

DMN2310UWQ-7 from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in SOT323 package, rated for 1.3A continuous drain current at V_GS = 4.5V, with R_DS(ON) = 200 mΩ max and AEC-Q101 qualified for automotive use. It serves as a low-voltage power switch in DC-DC converters and analog switching circuits.

For engineers reviewing the DMN2310UWQ-7 datasheet, DMN2310UWQ-7 pinout, DMN2310UWQ-7 application, or DMN2310UWQ-7 equivalent, key selection criteria include gate threshold voltage (0.45–0.95 V), input capacitance (38 pF), thermal resistance (226 °C/W), and automotive qualification status.

Technical Context

This MOSFET operates in enhancement mode with a low gate threshold enabling direct drive from 1.8V/2.5V logic. Its R_DS(ON) remains stable across -55°C to +150°C junction temperature, supported by normalized on-resistance curves showing <15% variation at V_GS = 4.5V.

Dynamic performance includes fast switching (t_D(ON) = 4.8 ns, t_F = 55 ns) and low gate charge (Q_g = 0.7 nC), optimized for high-frequency power management where conduction and switching losses must be jointly minimized.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	20 V - Maximum drain-source blocking voltage for 12V rail and USB PD auxiliary power switches.
R_DS(ON) @ 4.5V	200 mΩ max - Enables ≤260 mW conduction loss at 1.3A, suitable for thermally constrained PCB layouts.
I_D (continuous)	1.3 A @ T_A = 25°C - Supports load switching in portable battery-powered systems with minimal heatsinking.
C_iss	38 pF - Reduces gate drive power requirement and improves EMI behavior in high-frequency PWM applications.
Q_g	0.7 nC - Allows efficient drive with low-current GPIOs or compact gate drivers without excessive Miller effect.
T_J range	-55°C to +150°C - Validated for under-hood automotive modules and industrial control environments.
V_GS(TH)	0.45–0.95 V - Ensures reliable turn-on with 1.8V I/O microcontrollers and low-power logic families.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2016LFG-7	R_DS(ON) = 160 mΩ @ 4.5V; SOT23-3 package; higher current rating (2.0A).	Larger footprint and higher thermal mass; better suited for sustained 1.5A loads.	Select when higher continuous current and lower R_DS(ON) outweigh size constraints.
AO3400A	R_DS(ON) = 42 mΩ @ 10V but 200 mΩ @ 4.5V; same SOT23-3 footprint; no AEC-Q101 rating.	Non-automotive grade; wider V_GS(TH) range (0.7–1.4 V) reduces 1.8V drive margin.	Choose for cost-sensitive consumer electronics where automotive qualification is unnecessary.

Compared with DMN2310UWQ-7, DMN2016LFG-7 offers lower conduction loss in larger packages, while AO3400A trades qualification and gate drive compatibility for lower unit cost in non-automotive designs.

FAQ

Is DMN2310UWQ-7 suitable for 1.8V gate drive?

Yes. With a gate threshold voltage range of 0.45–0.95 V and guaranteed R_DS(ON) of 280 mΩ at V_GS = 2.5V and 380 mΩ at V_GS = 1.8V, it reliably turns on using 1.8V logic outputs. The low V_GS(TH) ensures strong enhancement even at minimum I/O voltage.

What is the maximum safe operating temperature for continuous use?

The device supports continuous operation up to +150°C junction temperature. At ambient +70°C with standard FR-4 PCB layout (2 oz copper, thermal bias), its 0.55 W power dissipation limit and 226 °C/W R_θJA allow ~1.1A continuous current before exceeding T_J(max).

Does DMN2310UWQ-7 include integrated ESD protection?

Yes. The device integrates ESD protection on all pins, meeting JEDEC JS-001 Class 2 (≥2 kV HBM) requirements. This eliminates need for external TVS diodes in typical board-level ESD environments per IEC 61000-4-2 Level 2.

Can DMN2310UWQ-7 replace a mechanical relay in automotive lighting?

Yes - as a solid-state alternative to SPST relays in interior lighting control. Its 1.3A rating, AEC-Q101 qualification, and robust body diode (I_S = 0.6A) support inductive load handling. However, external flyback protection is still required for solenoid-type actuators.
