Product details

Overview

DMN2053UW-13 from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in SOT323 package, optimized for low R_DS(ON) (56 mΩ @ V_GS = 4.5V) and fast switching in space-constrained power management circuits. It delivers 2.9 A continuous drain current at +25°C and supports 1.5V–4.5V logic-level gate drive, making it suitable for battery-powered DC-DC converters and load switching.

For engineers reviewing the DMN2053UW-13 datasheet, DMN2053UW-13 pinout, DMN2053UW-13 application, or DMN2053UW-13 equivalent, key selection criteria include its 1.0 V gate threshold voltage, 369 pF input capacitance, 3.6 nC total gate charge, and thermal resistance of 268 °C/W on FR-4 - all critical for low-power, high-density switching designs.

Technical Context

This MOSFET employs planar silicon technology with optimized channel geometry to achieve low on-resistance while maintaining robust body diode performance (V_SD = 0.7 V @ I_S = 1 A). Its gate threshold voltage range (0.35–1.0 V) ensures reliable turn-on with 1.8V–3.3V microcontroller outputs.

The device features low dynamic parameters: C_iss = 369 pF, Q_g = 3.6 nC, and t_F = 3.6 ns, enabling efficient operation in high-frequency (>1 MHz) synchronous buck stages and analog switch applications where minimal switching loss and charge injection matter.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	20 V - Maximum blocking voltage for 3.3V/5V rail-level switching
R_DS(ON)	56 mΩ @ V_GS = 4.5V - Enables <150 mW conduction loss at 2A load
I_D (max)	2.9 A @ T_A = +25°C - Supports compact point-of-load regulators without heatsinking
Q_g	3.6 nC - Reduces gate driver power demand in high-frequency PWM control
C_iss	369 pF - Limits Miller-induced shoot-through risk in half-bridge configurations
T_J range	−55°C to +150°C - Validated for automotive cabin and industrial ambient environments
V_GS(TH)	0.35–1.0 V - Ensures full enhancement with 1.8V GPIOs and low-voltage supervisors

Pinout & Package

Package: SOT323 - ultra-small surface-mount plastic case (2.15 mm × 2.10 mm × 0.95 mm), rated for 0.47 W dissipation on standard FR-4 PCB with minimum pad layout.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control electrode	Accepts 0–12 V logic-level signals; 4.1 Ω gate resistance minimizes ringing
S (Source)	Reference node for gate drive and current return	Internally tied to substrate; requires low-impedance ground path for stable switching
D (Drain)	Power output terminal	Connected to load or switching node; handles up to 20 V and pulsed 20 A currents

Key Features

Feature	Design Value
Low R_DS(ON) at 1.8V drive	93 mΩ enables use with 1.8V microcontrollers without level-shifting
Fast switching speed	t_F = 3.6 ns and t_D(OFF) = 12.5 ns reduce transition losses in >500 kHz SMPS
Low input capacitance	C_iss = 369 pF lowers gate drive current requirements and EMI generation
Green packaging	Halogen- and antimony-free compound meets IPC-1752A Class 3 material declarations
Moisture sensitivity	Level 1 per J-STD-020 - no bake required before reflow soldering

Applications

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
DMN2058UW-7	R_DS(ON) = 42 mΩ @ V_GS = 4.5V; higher I_D = 3.2 A; same SOT323 package	Better conduction efficiency above 2A; slightly higher C_iss (410 pF)	Select when lower steady-state loss at >2A load is prioritized over minimal gate charge
AO3400	R_DS(ON) = 44 mΩ @ V_GS = 10V but 65 mΩ @ V_GS = 4.5V; larger SOT23 package	Higher thermal resistance (300 °C/W); not optimized for sub-2.5V gate drive	Choose only if existing SOT23 footprint reuse is mandatory and 4.5V+ gate drive is guaranteed

Compared with DMN2053UW-13, DMN2058UW-7 offers lower conduction loss at high current but increases gate drive energy, while AO3400 sacrifices low-voltage drive capability and thermal performance for legacy footprint compatibility - making DMN2053UW-13 optimal for new 1.8V–3.3V logic-driven designs requiring balanced speed, loss, and size.

FAQ

What is the maximum continuous drain current for DMN2053UW-13 at +70°C ambient?

The DMN2053UW-13 supports 2.3 A continuous drain current at T_A = +70°C with standard FR-4 mounting (Note 6). This derating reflects its 178 °C/W thermal resistance under enhanced copper layout, ensuring safe operation in thermally dense PCBs without forced airflow.

Does DMN2053UW-13 have an integrated body diode, and what are its characteristics?

Yes - it includes a monolithic body diode rated for 1.0 A forward current with 0.7 V typical forward voltage at I_S = 1 A and V_GS = 0 V. The diode exhibits 6.0 ns reverse recovery time and 0.9 nC Q_RR, supporting moderate-frequency freewheeling in synchronous rectifier and H-bridge configurations.

Can DMN2053UW-13 be used with 1.5V gate drive, and what is its R_DS(ON) at that voltage?

Yes - it is fully specified down to V_GS = 1.5V, where R_DS(ON) is 140 mΩ (max) at I_D = 0.5 A. This enables direct interface with ultra-low-voltage supervisors and certain energy-harvesting PMICs, though conduction loss rises ~2.5× versus 4.5V drive.

Is the SOT323 package of DMN2053UW-13 compatible with standard reflow profiles?

Yes - its Level 1 moisture sensitivity rating per J-STD-020 means it can be processed using standard lead-free reflow profiles (peak 260°C) without pre-bake. The matte tin annealed leadframe ensures reliable solder joint formation per MIL-STD-202, Method 208.
