Product details
Overview
DMG4822SSDQ from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SO-8 package, rated for 30V VDSS, 21 mΩ RDS(ON) @ 10V VGS, and 10A continuous drain current at 25°C. It serves as a high-efficiency power switch in automotive DC-DC converters and analog switching circuits, qualified to AEC-Q101 with PPAP support.
For engineers reviewing the DMG4822SSDQ datasheet, DMG4822SSDQ pinout, DMG4822SSDQ application, or DMG4822SSDQ equivalent, key selection criteria include low gate charge (10.5 nC @ 10V), fast switching (tD(OFF) = 14.6 ns), thermal resistance (RθJA = 88.4 °C/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual N-channel MOSFET integrates two independent silicon die in a single SO-8 package with shared source terminals per channel (pins 1–4 and 5–8). Its low RDS(ON) and gate charge enable high-efficiency synchronous rectification and load switching in 12V automotive systems.
The device features matched threshold voltage (1–3 V) and low input capacitance (Ciss = 478.9 pF), supporting stable PWM control in buck converters. Thermal performance is validated across –55°C to +150°C junction range, with normalized on-resistance variation ≤1.7× over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage for 12V automotive rail protection and DC-DC primary-side switching |
| RDS(ON) | 21 mΩ @ 10V VGS - Enables <1.5W conduction loss at 8.5A, critical for thermally constrained PCB layouts |
| Qg | 10.5 nC @ 10V - Reduces gate drive power and enables >500 kHz switching in high-frequency converters |
| tD(OFF) | 14.6 ns - Limits dead-time losses in synchronous buck topologies with tight timing margins |
| RθJA | 88.4 °C/W - Defines thermal derating curve for FR-4 boards with minimum pad layout per datasheet |
| ID (max) | 10 A @ 25°C - Supports peak load currents in battery management and motor driver pre-driver stages |
| Ciss | 478.9 pF - Determines Miller effect magnitude and gate driver sizing for stable turn-on/turn-off |
Pinout & Package
Package: SO-8, surface-mount, lead-free, halogen-free, IATF 16949 certified manufacturing. Dimensions: 4.90 × 6.00 × 1.45 mm (L × W × H), moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source 1 / Drain 1 / Gate 1 / Source 1 | Pins 1 & 4 are Source 1; Pin 2 is Drain 1; Pin 3 is Gate 1 - forms first N-channel switch with common-source configuration |
| 5, 6, 7, 8 | Source 2 / Drain 2 / Gate 2 / Source 2 | Pins 5 & 8 are Source 2; Pin 6 is Drain 2; Pin 7 is Gate 2 - independent second N-channel switch, electrically isolated from Channel 1 |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) | 13.4 mΩ typical @ 10V - reduces conduction loss by ≥35% vs. legacy 30V MOSFETs in 12V automotive loads |
| Fast switching speed | tR = 7.9 ns, tF = 3.1 ns - minimizes transition losses in high-frequency (>300 kHz) DC-DC converters |
| AEC-Q101 qualification | PPAP-capable, IATF 16949 manufacturing - ensures supply chain traceability and failure rate compliance for automotive OEM programs |
| Low gate charge | Qgs = 1.8 nC, Qgd = 1.6 nC - lowers gate driver IC stress and enables use of low-power microcontroller GPIOs for direct drive |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3020LSDQ | Single-channel, 30V/20mΩ, same SO-8 footprint but no dual configuration | Requires two devices for dual-switch function; lacks internal channel isolation | Select when only one switch is needed or board layout permits duplication |
| NTMFS4C09NT1G | 30V/1.9mΩ, 15A, PowerPAK SO-8, lower RDS(ON) but higher Qg (22 nC) | Better conduction loss but slower switching; not AEC-Q101 qualified | Prefer for non-automotive high-current apps where thermal margin exceeds switching loss trade-off |
Compared with DMT3020LSDQ and NTMFS4C09NT1G, DMG4822SSDQ uniquely delivers dual-channel integration, AEC-Q101 qualification, and balanced gate charge (10.5 nC) for automotive synchronous converters-making it optimal where space, reliability, and timing precision are jointly constrained.

FAQ
What is the maximum continuous drain current for DMG4822SSDQ at 85°C ambient?
The DMG4822SSDQ supports 6.6A continuous drain current at TA = +85°C, derated from its 10A rating at 25°C. This value assumes operation on an FR-4 PCB with minimum recommended pad layout per datasheet Figure 6, and accounts for thermal resistance (RθJA = 88.4 °C/W) and junction temperature limit of +150°C.
Can DMG4822SSDQ be used in back-to-back configuration for reverse-current blocking?
Yes - each channel's intrinsic body diode (VSD = 0.4V typ @ 1A) and 30V VDSS rating allow reliable back-to-back connection. The dual-channel SO-8 layout enables compact implementation without inter-device routing, and the 1.68A avalanche current rating provides margin against transient reverse-energy events.
Is the SO-8 package of DMG4822SSDQ compatible with standard reflow profiles?
Yes - the device is qualified for moisture sensitivity level 1 per J-STD-020 and uses matte tin finish on copper leadframe, fully compliant with IPC/JEDEC J-STD-020D. Standard Pb-free reflow profiles (peak 260°C, 60 sec max above 217°C) are supported without preconditioning.
Does DMG4822SSDQ require external gate resistors for automotive PWM applications?
Not strictly required, but recommended: the 1.1Ω gate resistance (Rg) and 10.5 nC total gate charge permit direct MCU GPIO drive at ≤100 kHz. For >200 kHz PWM or EMI-sensitive environments, a 5–10Ω series gate resistor improves ringing suppression and dV/dt control without compromising switching speed.
