Product details
Overview
DMG2302UQ-7 from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in SOT23 package, featuring 90mΩ RDS(ON) at VGS = 4.5V, 4.2A continuous drain current at 25°C, and AEC-Q101 qualification for automotive use. It serves as a low-loss power switch in DC-DC boost converters, load switching, and analog signal routing.
For engineers reviewing the DMG2302UQ-7 datasheet, DMG2302UQ-7 pinout, DMG2302UQ-7 application, or DMG2302UQ-7 equivalent, key selection criteria include gate threshold voltage (0.4–1.0V), dynamic capacitances (Ciss = 594pF), thermal resistance (RθJA = 156°C/W), and automotive-grade reliability under IATF 16949 manufacturing.
Technical Context
This MOSFET employs planar trench-gate technology optimized for low RDS(ON) while maintaining fast switching (tD(on) = 7.4ns, tD(off) = 28.1ns) and low gate charge (Qg = 7.0nC). Its 0.4–1.0V VGS(TH) enables direct drive from 1.8V/2.5V logic and microcontroller GPIOs without level shifting.
The device integrates a body diode with VSD = 0.75V at 1A and exhibits stable RDS(ON) over temperature (1.8× increase from −55°C to +150°C at VGS = 4.5V). Its SOT23 footprint supports high-density PCB layouts in space-constrained power management modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20V - Maximum drain-source blocking voltage for 12V rail switching and boost converter topologies |
| RDS(ON) | 90mΩ @ VGS = 4.5V - Enables ≤330mW conduction loss at 3.6A, critical for thermally constrained SOT23 designs |
| ID (continuous) | 4.2A @ TA = 25°C - Supports high-current load switching in portable battery-powered systems |
| Ciss | 594pF - Low input capacitance reduces gate drive power and improves switching efficiency at >1MHz frequencies |
| Qg | 7.0nC - Enables fast turn-on with minimal gate driver current demand (e.g., <1mA avg. at 1MHz) |
| TJ range | −55°C to +150°C - Validated operation across automotive under-hood and industrial ambient conditions |
Pinout & Package
Package: SOT23 - 3-pin surface-mount plastic package (2.9mm × 1.3mm × 1.0mm), moisture sensitivity level 1, matte tin-plated copper leadframe, UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for N-channel conduction | Connected to ground or low-side reference; internal bond wire limits pulsed current to 27A |
| 2 (Gate) | Control electrode for channel formation | High-impedance input (IGSS ≤ ±100nA); requires <7nC charge for full enhancement |
| 3 (Drain) | Power output terminal | Handles 20V blocking and 4.2A steady-state current; thermally coupled to PCB copper for heat dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 2.5V drive | 120mΩ - Enables reliable switching from 2.5V microcontrollers and logic outputs without gate boosting |
| Fast switching speed | tD(on) = 7.4ns, tf = 6.7ns - Reduces switching losses in high-frequency DC-DC converters (>500kHz) |
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS power stages |
| Green, RoHS-compliant construction | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); lead-free per EU directives 2011/65/EU and 2015/863/EU |
Applications
| Automotive Body Control Module | USB Power Delivery Switch |
|---|---|
Use Scenario: Controlling 12V accessory loads (e.g., LED lighting, window motors) in vehicle BCMs with PWM dimming and fault reporting. IC Role / Device Role / Timing Role: Low-side load switch with fast turn-off to suppress inductive kickback during motor stall detection. Use Value: 90mΩ RDS(ON) minimizes voltage drop and self-heating during sustained 3A loads, extending component lifetime in sealed enclosures. |
Use Scenario: Enabling/disabling VBUS power paths in USB-C PD sink devices compliant with USB-IF specifications. IC Role / Device Role / Timing Role: High-speed, low-leakage power switch isolating downstream ports during hot-plug events. Use Value: 100nA max IGSS and 1μA max IDSS prevent standby current leakage that would violate USB-C 50μA sleep budget. |
| Portable Boost Converter | Industrial Sensor Interface |
Use Scenario: Synchronous rectifier in 3.3V-to-5V/9V boost regulators for handheld medical instruments and IoT edge nodes. IC Role / Device Role / Timing Role: High-efficiency synchronous FET replacing Schottky diode to reduce conduction loss and improve light-load efficiency. Use Value: 7.0nC Qg allows clean gate drive from low-power boost controller ICs (e.g., AP3418), minimizing gate driver overhead. |
Use Scenario: Multiplexing analog sensor signals (e.g., thermistors, RTDs) into shared ADC inputs in programmable logic controllers. IC Role / Device Role / Timing Role: Low-distortion analog switch with minimal on-resistance flatness (±5% over 0–3V signal range). Use Value: 0.75V VSD and 13S |Yfs| ensure low THD and predictable channel resistance for precision 16-bit measurement systems. |
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 |
|---|---|---|---|
| DMN2055UQ | Same SOT23 package; higher RDS(ON) (110mΩ @ 4.5V), lower ID (3.5A), identical AEC-Q101 qualification | Suitable where marginally higher conduction loss is acceptable for cost-sensitive automotive modules | Select when thermal budget allows ≥15% higher I²R loss and gate drive capability is limited to <5V |
| AO3400 | Non-automotive grade; RDS(ON) = 44mΩ @ 10V but 100mΩ @ 4.5V; no AEC-Q101 or PPAP support | Applicable only in commercial-grade consumer electronics with no automotive qualification requirement | Choose only for non-automotive designs where lowest RDS(ON) at 10V drive is prioritized over reliability documentation |
Compared with DMN2055UQ and AO3400, the DMG2302UQ-7 delivers optimal balance of low 4.5V-drive RDS(ON), automotive qualification, and SOT23 thermal performance-making it the preferred choice for safety-critical, space-constrained 12V power switches.

FAQ
Is DMG2302UQ-7 suitable for 1.8V logic-level gate drive?
Yes. With a guaranteed gate threshold voltage (VGS(TH)) of 0.4–1.0V and RDS(ON) = 120mΩ at VGS = 2.5V, the DMG2302UQ-7 fully enhances using standard 1.8V GPIO outputs. Its low Ciss (594pF) ensures minimal gate charging delay even at low drive strength.
What is the maximum safe operating temperature for continuous 4.2A drain current?
Continuous 4.2A operation is rated only at TA = +25°C with minimum FR-4 pad layout. At TA = +70°C, the derated current is 3.4A. Junction temperature must remain ≤+150°C; with RθJA = 156°C/W, power dissipation must be limited to ≤0.5W above 70°C ambient.
Does DMG2302UQ-7 include integrated ESD protection?
No. The DMG2302UQ-7 does not integrate dedicated ESD protection circuitry. Its gate oxide is rated for ±8V VGS; external TVS or RC filtering is recommended for board-level ESD immunity per IEC 61000-4-2 Level 4 (±8kV contact) in automotive environments.
Can DMG2302UQ-7 replace Si2302DS in existing designs?
Yes, with verification. Both are SOT23 N-channel MOSFETs with similar RDS(ON) (90mΩ vs. 85mΩ @ 4.5V) and pinout. However, DMG2302UQ-7 adds AEC-Q101 qualification, tighter VGS(TH) distribution (0.4–1.0V vs. 0.5–1.2V), and lower Coss (64.5pF vs. 75pF), improving switching consistency in automotive applications.
