Product details
Overview
DMN52D0UWQ-7 from Diodes Incorporated is a 50V N-channel enhancement-mode MOSFET in SOT323 package, qualified to AEC-Q101 with VGS(TH) ≤ 1.0 V, RDS(ON) = 2.0 Ω @ VGS = 5 V, and ID = 380 mA at TA = +25°C. It serves as a low-voltage load switch in automotive body electronics.
For engineers reviewing the DMN52D0UWQ-7 datasheet, DMN52D0UWQ-7 pinout, DMN52D0UWQ-7 application, or DMN52D0UWQ-7 equivalent, key selection criteria include gate threshold voltage compatibility with 1.8V/2.5V logic, on-resistance stability over temperature, AEC-Q101 qualification status, and SOT323 thermal performance under pulsed load conditions.
Technical Context
This MOSFET employs planar silicon technology optimized for low-VGS(TH) and fast switching in space-constrained automotive modules. Its RDS(ON) remains stable across −55°C to +150°C junction temperatures, with normalized variation ≤ 1.6× at 150°C (VGS = 5 V).
The device integrates ESD protection per HBM ≥ 2 kV and features ultra-low input capacitance (Ciss = 39 pF) and gate charge (Qg = 0.8 nC @ VGS = 4.5 V), enabling efficient drive from low-power microcontrollers in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 50 V - supports 24V automotive supply rails with margin against transients |
| RDS(ON) | 2.0 Ω @ VGS = 5 V - enables <100 mW conduction loss at 380 mA load current |
| VGS(TH) | ≤ 1.0 V - ensures full enhancement with 1.8V GPIOs and reduces drive circuit complexity |
| ID (continuous) | 380 mA @ TA = +25°C - suitable for LED drivers, sensor biasing, and small solenoid control |
| Ciss | 39 pF - minimizes gate drive power and improves switching efficiency at >100 kHz |
| Qg | 0.8 nC @ VGS = 4.5 V - allows fast turn-on with <1 µs delay using standard 50Ω driver |
| TJ range | −55°C to +150°C - meets under-hood temperature requirements for AEC-Q101-compliant designs |
Pinout & Package
Package: SOT323 - surface-mount plastic package with 3 terminals, 0.006 g mass, UL 94V-0 rated molding compound, and matte tin–annealed Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel low-threshold MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN52D0UDWQ-7 | SOT363 package (dual-channel), same RDS(ON) and VGS(TH), higher thermal resistance (RθJA = 300°C/W) | Used where dual independent switches replace discrete singles in compact BCU layouts | Select when board space permits dual-device integration and shared gate drive simplifies routing |
| NX3008NBK,115 | 30V VDSS, 1.5 Ω RDS(ON) @ 4.5V, no AEC-Q101 qualification, smaller 0.65 mm pitch | Targeted at consumer-grade infotainment peripherals, not under-hood automotive | Choose only for non-automotive applications where 30V rating suffices and qualification is not required |
Compared with DMN52D0UWQ-7, DMN52D0UDWQ-7 offers dual functionality at the cost of thermal derating, while NX3008NBK,115 trades automotive reliability for lower on-resistance and finer pitch-neither is a drop-in replacement without layout or qualification review.

FAQ
Is DMN52D0UWQ-7 suitable for 1.8V logic-level drive?
Yes. With a maximum gate threshold voltage of 1.0 V and typical VGS(TH) of 0.49 V, the DMN52D0UWQ-7 fully enhances at 1.8V gate drive, delivering RDS(ON) ≤ 4.0 Ω at 50 mA. This enables direct connection to 1.8V microcontroller GPIOs without level-shifting circuitry.
What is the maximum pulsed drain current rating?
The DMN52D0UWQ-7 supports 1.2 A pulsed drain current (IDM) under 10 µs pulse width and 1% duty cycle conditions. This rating assumes proper PCB thermal design per the datasheet's recommended pad layout on 2 oz copper FR-4.
Does this part include integrated ESD protection?
Yes. The DMN52D0UWQ-7 incorporates on-chip ESD protection rated to ≥ 2 kV per Human Body Model (HBM), as confirmed in the "Features and Benefits" section and validated in Diodes' internal qualification testing per JESD22-A114.
Can DMN52D0UWQ-7 be used in place of a mechanical relay for low-power loads?
Yes. With 380 mA continuous current capability, <1 V gate drive requirement, and 50V blocking voltage, it replaces electromechanical relays in loads such as LED indicators, small solenoids, and sensor biasing-reducing size, wear-out failure modes, and acoustic noise.
