Product details

Overview

DMN2300UFD-7 from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in a X1-DFN1212-3 package, optimized for low-voltage load switching with R_DS(on) = 200 mΩ @ V_GS = 4.5V, I_D = 1.73 A, and gate threshold voltage V_GS(th) = 0.45–0.95 V. It supports high-reliability automotive applications per AEC-Q101 and features ESD-protected gate (2 kV HBM).

For engineers reviewing the DMN2300UFD-7 datasheet, DMN2300UFD-7 pinout, DMN2300UFD-7 application, or DMN2300UFD-7 equivalent, key selection criteria include low gate threshold for 1.8V–2.5V logic compatibility, fast switching (t_D(on) = 4.92 ns), thermal resistance R_θJA = 130 °C/W on 15 mm × 15 mm PCB, and qualification for automotive-grade power management.

Technical Context

This MOSFET operates as a single N-channel enhancement-mode switch with integrated body diode, designed for unidirectional load control in space-constrained DC/DC and battery-powered systems. Its low V_GS(th) enables direct drive from 1.8V GPIOs, while its R_DS(on) scalability across 1.5V–4.5V gate voltages supports flexible biasing in multi-rail power domains.

The device uses a surface-mount DFN package with exposed drain pad for thermal conduction, and its dynamic parameters-including C_iss = 67.6 pF, Q_g = 0.89–2 nC, and t_f = 10.6 ns-support efficient PWM operation at frequencies up to several hundred kHz in compact load-switch designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	20 V - Maximum drain-source blocking voltage for 3.3V/5V system rail protection
R_DS(on)	200 mΩ @ V_GS = 4.5V - Enables ≤173 mW conduction loss at 1.73 A continuous current
I_D (max)	1.73 A @ T_A = 25°C - Sustains full-load current on standard FR4 with 2 oz copper
V_GS(th)	0.45–0.95 V - Ensures turn-on with 1.2V logic or weak pull-up sources
Q_g	0.89–2 nC - Determines gate drive energy and switching loss in high-frequency load switching
R_θJA	130 °C/W - Limits junction rise to ~125°C under 0.96 W steady-state dissipation
E_SD	2 kV HBM - Protects gate during board handling and low-energy ESD events

Pinout & Package

Package: X1-DFN1212-3 (1.2 mm × 1.2 mm × 0.5 mm), thermally enhanced with exposed drain pad. Molded green compound, UL 94V-0 rated, MSL Level 1.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Source terminal	Reference node for gate drive; connected to ground or low-side return path
2 (Gate)	Control input	Receives logic-level signal; low capacitance (C_iss = 67.6 pF) minimizes drive burden
3 (Drain)	Power output	Exposed pad connects to PCB copper pour for thermal and current conduction

Key Features

Feature	Design Value
Low gate threshold voltage	V_GS(th) down to 0.45 V enables reliable turn-on from 1.2V–1.8V microcontroller outputs
Fast switching performance	t_D(on) = 4.92 ns and t_f = 10.62 ns support high-efficiency PWM at ≥500 kHz
AEC-Q101 qualified	Validated for automotive temperature range (−55°C to +150°C) and reliability stress tests
Green, RoHS-compliant construction	Halogen- and antimony-free molding compound; NiPdAu-plated terminals ensure solderability
ESD-protected gate	2 kV HBM rating reduces risk of field failure during assembly and handling

Applications

Battery Protection Circuit

USB Power Delivery Switch

Use Scenario: Isolating Li-ion battery from system during overvoltage or short-circuit fault detection.

IC Role / Device Role / Timing Role: Low-side load switch controlled by battery management IC to disconnect pack within <100 µs.

Use Value: 200 mΩ R_DS(on) limits voltage drop to <350 mV at 1.7 A, preserving battery runtime and enabling accurate voltage sensing.

Use Scenario: Enabling/disabling 5 V USB power rail in portable docking stations with hot-plug detection.

IC Role / Device Role / Timing Role: High-speed, low-threshold switch driven directly by USB PD controller GPIO.

Use Value: Sub-1 V V_GS(th) ensures robust turn-on with 1.8 V logic; fast t_f prevents bus glitch during hot-swap transitions.

Automotive Body Control Module

IoT Sensor Node Power Gating

Use Scenario: Controlling LED lighting or small solenoids in door modules or mirror controls.

IC Role / Device Role / Timing Role: AEC-Q101-qualified N-channel switch replacing mechanical relays for silent, wear-free actuation.

Use Value: 150°C max operating temperature and −55°C cold-start capability meet automotive ambient requirements without derating.

Use Scenario: Powering BLE/Wi-Fi sensors only during active measurement cycles to extend coin-cell life.

IC Role / Device Role / Timing Role: Ultra-low-leakage (I_DSS ≤ 1 µA) switch enabling >10-year shelf life in always-off state.

Use Value: Gate leakage <10 µA and sub-µA off-state drain current minimize standby power loss in energy-harvesting nodes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel load switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2016LFG-7	R_DS(on) = 160 mΩ @ V_GS = 4.5V; higher I_D = 2.2 A; same X1-DFN1212-3 package	Suitable for higher-current loads but requires tighter gate drive margin due to V_GS(th) = 0.5–1.2 V	Select when lower conduction loss at >1.7 A is critical and gate drive can support wider V_GS(th) spread.
AO3400A	R_DS(on) = 28 mΩ @ V_GS = 10V; V_GS(th) = 0.7–1.4 V; SO-23 package (larger footprint)	Requires 3.3V+ logic for reliable turn-on; not AEC-Q101 qualified	Choose for non-automotive, higher-current applications where board area is less constrained and qualification is not required.

Compared with DMN2300UFD-7, DMN2016LFG-7 offers lower R_DS(on) at identical package size but looser V_GS(th) tolerance, while AO3400A delivers significantly lower on-resistance but sacrifices automotive qualification and gate-drive compatibility with sub-2V logic.

FAQ

What is the maximum continuous drain current for DMN2300UFD-7 at 85°C ambient?

The maximum continuous drain current is 1.34 A at T_A = 85°C when mounted on a 15 mm × 15 mm × 1.6 mm FR4 PCB with 2 oz copper. This derating reflects thermal limitations under still-air conditions and assumes proper PCB copper pour design for the exposed drain pad.

Does DMN2300UFD-7 require a gate resistor for typical load-switch operation?

A gate resistor is recommended to damp ringing and limit peak gate current, especially when driven by high-speed GPIOs. With C_iss = 67.6 pF and Q_g ≈ 1.2 nC, a 10–47 Ω resistor balances switching speed and EMI control without compromising t_D(on) < 5 ns performance.

Can DMN2300UFD-7 be used in reverse-conduction (source-to-drain) applications?

No - the internal body diode conducts only from source to drain. Reverse conduction (drain-to-source) is blocked unless externally paralleled with a Schottky diode. The device is specified and characterized exclusively for forward (drain-to-source) switching operation.

Is the X1-DFN1212-3 package compatible with standard reflow profiles for lead-free soldering?

Yes - the package is qualified for JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard IPC/JEDEC lead-free reflow profiles (peak 260°C). Its NiPdAu-plated terminals ensure wetting reliability, and the green molding compound withstands multiple thermal cycles without delamination.
