Product details
Overview
DMN52D0UVQ-7 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET rated for 50V drain-source voltage, with RDS(ON) of 2.0Ω @ VGS = 5V and 4.0Ω @ VGS = 1.8V, delivering 480mA continuous drain current at +25°C. It serves as a compact, low-threshold load switch in automotive battery- and power-management systems.
For engineers reviewing the DMN52D0UVQ-7 datasheet, DMN52D0UVQ-7 pinout, DMN52D0UVQ-7 application, or DMN52D0UVQ-7 equivalent, key selection criteria include its AEC-Q101 qualification, ultra-low 1.0V max gate threshold, SOT563 ultra-small package, dual-channel integration, and ESD protection-critical for space-constrained automotive load switching.
Technical Context
This dual MOSFET integrates two independent N-channel devices in a single SOT563 package, each featuring an integrated gate protection diode and body diode. Its 1.0V maximum VGS(TH) enables direct interfacing with 1.8V/2.5V logic controllers without level shifting.
The device operates across –55°C to +150°C junction temperature range and supports pulsed drain currents up to 1.2A. Thermal resistance is 139°C/W (min pad layout) and 261°C/W (standard FR-4), confirming suitability for thermally constrained automotive PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 50V - supports 12V/24V automotive battery rails with margin against transients |
| RDS(ON) @ VGS = 5V | 2.0Ω max - limits conduction loss to ≤480mW at 480mA, enabling efficient low-power switching |
| VGS(TH) max | 1.0V - ensures full turn-on with 1.8V I/O domains, eliminating need for gate drivers in microcontroller-driven loads |
| Ciss | 39pF - reduces gate drive energy and speeds switching in high-frequency PWM control (e.g., LED dimming) |
| Qg @ VGS = 4.5V | 0.8nC - enables fast turn-on with minimal MCU GPIO current demand (≤1mA peak) |
| TJ range | –55°C to +150°C - meets under-hood thermal requirements per AEC-Q101 Grade 1 |
Pinout & Package
Package: SOT563 - ultra-small 1.6mm × 1.6mm × 0.6mm surface-mount package with 6 terminals, optimized for high-density automotive PCB layouts and compatible with standard reflow profiles (MSL Level 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1 | Drain of Channel 1 | Primary high-side or low-side power path terminal; connects to load or supply rail |
| S1 | Source of Channel 1 | Return path for Channel 1; tied to ground or intermediate node depending on topology |
| G1 | Gate of Channel 1 | Logic-controlled input; internal ESD diode protects against ±12V transients |
| D2 | Drain of Channel 2 | Independent second power switch; enables dual-load control without discrete parts |
| S2 | Source of Channel 2 | Separate return path allows isolated channel operation or parallel configuration |
| G2 | Gate of Channel 2 | Independent control input; identical threshold and drive requirements as G1 |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN52D0UDWQ-7 | Same die, but in SOT363 package (larger footprint, 2.1mm × 2.3mm); RDS(ON) identical, but RθJA = 200°C/W (vs. 139°C/W for SOT563 min layout) | Preferred where manual rework or thermal relief is prioritized over board area; not suitable for ultra-dense layouts | Select when thermal margin > space constraint, or when legacy SOT363 land patterns exist |
| DMN3022LSD-13 | Single-channel 30V MOSFET in SOT23-6; RDS(ON) = 2.2Ω @ 4.5V; no AEC-Q101 qualification; VGS(TH) = 1.2V max | Requires two devices for dual functionality; lacks automotive qualification and integrated ESD protection | Only for non-automotive, cost-sensitive industrial applications where AEC-Q101 is not required |
Compared with DMN52D0UDWQ-7, the DMN52D0UVQ-7 offers superior thermal performance in minimal area; compared with DMN3022LSD-13, it delivers certified automotive reliability, true dual-channel integration, and lower gate threshold-making it the sole qualified option for production automotive load switching.

FAQ
Is DMN52D0UVQ-7 qualified for automotive use?
Yes. The DMN52D0UVQ-7 is fully AEC-Q101 qualified, manufactured in IATF 16949-certified facilities, and supported by PPAP documentation. It meets automotive-grade requirements for temperature cycling, humidity testing, and mechanical shock, with guaranteed operation from –55°C to +150°C junction temperature.
What is the maximum continuous drain current per channel?
The maximum continuous drain current is 480mA per channel at TA = +25°C with VGS = 5V, derating to 380mA at TA = +70°C. This rating assumes mounting on an FR-4 PCB with 2oz copper and minimum recommended pad layout per Diodes' datasheet Figure 7.
Does DMN52D0UVQ-7 include ESD protection?
Yes. Each gate includes an integrated ESD protection diode rated to ±12V, verified per HBM (Human Body Model) and CDM (Charged Device Model) standards. This eliminates the need for external TVS diodes in typical automotive signal routing environments.
Can DMN52D0UVQ-7 be used in parallel configurations?
Yes-its matched dual-channel structure and tight RDS(ON) tolerance (1.0–2.0Ω typ at VGS = 5V) support paralleling for higher current capability. However, individual gate drive and thermal isolation must be maintained; total current should not exceed 960mA (2 × 480mA) with appropriate derating for ambient temperature and PCB copper area.
