Product details
Overview
DMG1023UVQ-7 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SOT563 package, rated for -20V VDSS, 0.75Ω RDS(on) at VGS = -4.5V and -1.03A ID, with AEC-Q101 qualification for automotive power management. It serves as a compact, low-RDS(on) load switch or synchronous rectifier in space-constrained DC-DC converters.
For engineers reviewing the DMG1023UVQ-7 datasheet, DMG1023UVQ-7 pinout, DMG1023UVQ-7 application, or DMG1023UVQ-7 equivalent, key selection criteria include gate threshold voltage (-0.5 to -1.0V), low input capacitance (59pF Ciss), fast switching (tD(on) = 5.1ns), ESD-protected gate, and thermal resistance (235°C/W RθJA) on FR-4 PCB.
Technical Context
This dual P-channel MOSFET integrates two matched enhancement-mode transistors in a single SOT563 package, sharing no internal connection between channels-each has independent gate, source, and drain terminals. Its low VGS(th) enables direct drive from 3.3V logic, while low Ciss and Qg (622pC) support high-frequency switching up to several MHz.
The device operates across -55°C to +150°C, with RDS(on) increasing only ~1.5× from 25°C to 125°C at VGS = -4.5V. Its ESD protection (HBM >2kV) and AEC-Q101 qualification confirm suitability for automotive body control modules and infotainment power rails where reliability under thermal cycling and transient stress is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Maximum blocking voltage before avalanche conduction; supports 12V automotive systems with margin. |
| RDS(on) | 0.75Ω @ VGS = -4.5V - Enables ≤0.8W conduction loss at 1.03A; suitable for <1W load switches. |
| ID | -1.03A @ TA = +25°C - Continuous current rating with standard FR-4 layout; derates to -0.68A at +70°C. |
| Ciss | 59pF - Low input capacitance reduces gate drive power and speeds turn-on; critical for high-efficiency buck converters. |
| tD(on) | 5.1ns - Short turn-on delay minimizes dead-time losses in synchronous rectification topologies. |
| RθJA | 235°C/W - Thermal resistance measured on 2oz copper FR-4; requires thermal pad design for >300mW continuous dissipation. |
| VGS(th) | -0.5 to -1.0V - Low threshold allows full enhancement with 3.3V GPIO; avoids need for level-shifting circuitry. |
Pinout & Package
Package: SOT563 - 6-pin ultra-small surface-mount package (1.60 × 1.60 × 0.60 mm), molded green compound, moisture sensitivity level 1, matte tin-plated leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S1 | Source of Channel 1 | Common return path for first MOSFET; electrically isolated from S2; connects to local ground or low-side rail. |
| D1 | Drain of Channel 1 | High-side switching node for Channel 1; handles bidirectional current in load-switch or reverse-polarity protection. |
| G1 | Gate of Channel 1 | Control terminal for Channel 1; requires ≤±6V drive; ESD-protected; drives with 3.3V/5V logic directly. |
| S2 | Source of Channel 2 | Independent source terminal for second MOSFET; not internally tied to S1; enables dual-rail or mirrored topology use. |
| D2 | Drain of Channel 2 | Second high-side switching node; supports independent load control or complementary half-bridge configuration. |
| G2 | Gate of Channel 2 | Independent control input; identical electrical characteristics to G1; allows asynchronous or synchronized dual-channel operation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent P-channel topology | Two fully isolated MOSFETs in one SOT563 footprint-reduces board area by ~40% vs. discrete SOT23 solutions. |
| Low RDS(on) at low VGS | 0.75Ω @ -4.5V enables efficient 3.3V-driven load switching without gate boosters or charge pumps. |
| ESD-protected gate | HBM >2kV per JESD22-A114 - eliminates need for external gate protection diodes in production assemblies. |
| AEC-Q101 qualified | Validated for automotive temperature range (-55°C to +150°C), PPAP-capable, manufactured in IATF 16949 facilities. |
| Green, RoHS-compliant construction | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); UL 94V-0 rated molding compound. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG1012UVT-7 | Higher RDS(on) (1.2Ω @ -4.5V), same SOT563 package, lower ID (-0.7A), no AEC-Q101 qualification. | Targeted at cost-sensitive consumer electronics-not automotive or industrial-grade designs. | Select when AEC-Q101 is unnecessary and higher on-resistance is acceptable for lower-cost BOMs. |
| AOB410L | Single-channel P-MOSFET in SO-8, RDS(on) = 0.55Ω @ -4.5V, higher ID (-4.5A), no dual-channel integration. | Requires two devices and larger board area; suited for higher-current (>1.5A) single-load applications. | Choose when higher current handling is required and board space permits SO-8 footprints. |
Compared with DMG1023UVQ-7, DMG1012UVT-7 trades automotive qualification and lower RDS(on) for cost reduction, while AOB410L offers higher current capacity but sacrifices integration density and dual-channel control-making DMG1023UVQ-7 optimal for space-constrained, AEC-Q101–compliant dual-load switching.

FAQ
Is DMG1023UVQ-7 pin-compatible with other SOT563 dual MOSFETs?
No-pin assignment is unique to this device: S1-D1-G1-S2-D2-G2 in top-view order. Competing dual P-channel SOT563 parts like DMG1012UVT-7 use different pinouts (e.g., G1-S1-D1-G2-S2-D2). Always verify pin mapping against the schematic symbol and physical layout before PCB design.
What is the maximum safe operating temperature for continuous use?
The junction temperature must not exceed +150°C. With RθJA = 235°C/W and PD = 0.53W max, ambient temperature must stay below +30°C for full-rated current (1.03A) on standard FR-4. Derating is required above that-e.g., 0.68A at +70°C ambient per datasheet.
Does DMG1023UVQ-7 support reverse-current blocking in battery backup circuits?
Yes-the intrinsic body diode conducts from source to drain (S→D) when VSD > 0.8V. In typical high-side switch configuration (source tied to VIN, drain to load), it blocks reverse current from load to source, preventing backfeed during battery switchover or fault conditions.
Can DMG1023UVQ-7 be driven directly from a 3.3V microcontroller GPIO?
Yes-its VGS(th) range (-0.5V to -1.0V) ensures full enhancement at VGS = -3.3V. Gate charge is low (Qg = 622pC), so standard MCU GPIOs can drive it without external buffers, provided layout minimizes gate loop inductance for clean switching.
