Product details
Overview
DMP3056LSDQ-13 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SO-8 package, rated for -30V VDSS, 45mΩ RDS(ON) @ VGS = -10V, and -6.9A continuous drain current at +25°C. It serves as a compact, AEC-Q101-qualified power switch for synchronous buck converters and automotive LED backlighting circuits.
For engineers reviewing the DMP3056LSDQ-13 datasheet, DMP3056LSDQ-13 pinout, DMP3056LSDQ-13 application, or DMP3056LSDQ-13 equivalent, key selection criteria include low gate threshold (-1.0 to -2.1V), fast switching (tF = 14.7ns), dual-channel thermal coupling, and IATF 16949-manufactured traceability for automotive-grade reliability.
Technical Context
This dual P-channel MOSFET integrates two matched enhancement-mode transistors in a single SO-8 package with shared thermal mass, enabling high-efficiency synchronous rectification in DC-DC converters where negative gate drive simplifies control. Its low RDS(ON) at -4.5V (65mΩ) supports 5V logic-level drive in battery-powered systems.
The device features low input capacitance (Ciss = 722pF), low gate charge (QG = 6.8nC @ -4.5V), and tight VGS(TH) distribution (±0.2V over temperature), ensuring predictable turn-on timing and reduced gate driver losses in high-frequency (>500kHz) power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - Withstands reverse-biased drain-source voltage up to 30V in automotive 24V systems with margin. |
| RDS(ON) | 45mΩ @ VGS = -10V - Enables ≤0.3W conduction loss at 6.9A, critical for thermally constrained PCB layouts. |
| ID (TA = +25°C) | -6.9A - Supports sustained load current in compact 2.5W power dissipation envelope (RθJA = 50°C/W). |
| VGS(TH) | -1.0 to -2.1V - Ensures full enhancement with standard 3.3V/5V microcontroller GPIO without level-shifting. |
| Ciss | 722pF - Limits gate drive energy requirement to ~3.2nJ per switch cycle at 5V swing, reducing driver IC stress. |
| tF | 14.7ns - Minimizes overlap conduction loss in synchronous buck topologies operating above 1MHz. |
| QG | 6.8nC @ -4.5V - Allows direct drive from low-power MCU pins with <10mA peak gate current capability. |
Pinout & Package
Package: SO-8 (Surface-Mount, 8-pin, 4.9mm × 6.0mm footprint, 1.27mm pitch). Molded green plastic, matte tin-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (D1) | Drain of Channel 1 | Main high-side current path for first MOSFET; electrically tied to exposed pad for thermal relief. |
| 2 (S1) | Source of Channel 1 | Return node for Channel 1; referenced to gate drive ground in half-bridge configurations. |
| 3 (G1) | Gate of Channel 1 | Control terminal for Channel 1; requires <6.8nC charge for full enhancement at -4.5V. |
| 4 (S2) | Source of Channel 2 | Shared source connection with Pin 2 in common-source dual configuration; enables parallel operation. |
| 5 (D2) | Drain of Channel 2 | Independent drain path for second MOSFET; isolated from D1 for dual-switch applications. |
| 6 (G2) | Gate of Channel 2 | Independent control input; allows asynchronous or complementary switching with Channel 1. |
| 7, 8 | Exposed Pad / Thermal Pad | Internally connected to both drains (D1/D2); must be soldered to PCB copper pour for thermal management. |
Key Features

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC3025LSDQ-13 | Lower RDS(ON) (30mΩ @ -10V), higher QG (12.5nC), same SO-8 package | Better conduction efficiency but slower switching; unsuitable for >1MHz designs | Select when thermal budget dominates over switching loss, e.g., 12V industrial power supplies with <500kHz switching. |
| SI7850DP-T1-GE3 | Higher VDSS (-40V), higher RDS(ON) (70mΩ @ -4.5V), different pinout (D1/G1/S1/S2/G2/D2) | Requires PCB layout change; better for 36V transient immunity but less efficient at 5V drive | Choose only if system requires -40V rating and layout revision is acceptable; not drop-in compatible. |

FAQ
What is the maximum continuous drain current for DMP3056LSDQ-13 at +70°C ambient?
The maximum continuous drain current is -5.8A at TA = +70°C, derated from -6.9A at +25°C per the datasheet's thermal characteristics table. This reflects junction-to-ambient thermal resistance (RθJA = 50°C/W) and SO-8 package limitations under standard PCB mounting conditions.
Is the exposed pad electrically connected, and how should it be handled on the PCB?
Yes-the exposed pad (Pins 7 and 8) is internally connected to both drains (D1 and D2). It must be soldered to a dedicated thermal copper pour on the PCB using at least nine 0.3mm vias to an internal ground plane to achieve the specified RθJA = 50°C/W and prevent thermal runaway during sustained -6.9A operation.
Does DMP3056LSDQ-13 support gate drive from a 3.3V microcontroller without external level shifting?
Yes-its gate threshold voltage range (-1.0V to -2.1V) ensures full enhancement with 3.3V logic-level drive (VGS = -3.3V), delivering RDS(ON) ≤ 65mΩ at -5.0A. No level shifter is required, though gate resistor selection (≥10Ω) is recommended to damp ringing due to low Ciss/Crss ratio.
How does the dual-channel structure affect thermal performance compared to two discrete SO-8 MOSFETs?
Both channels share the same die substrate and thermal pad, resulting in coupled junction temperatures. Under unbalanced loading, the hotter channel raises the other's junction temperature by up to 8°C-verified in Diodes' thermal simulation models. Layout must assume worst-case mutual heating, not independent derating.
