Product details
Overview
DMP4047SSDQ-13 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SO-8 package, rated for -40V VDS, 45mΩ RDS(on) at VGS = -10V, and -6.5A continuous drain current; used in high-efficiency DC-DC converters and backlighting power stages where compact dual-channel reverse-polarity switching is required.
For engineers reviewing the DMP4047SSDQ-13 datasheet, DMP4047SSDQ-13 pinout, DMP4047SSDQ-13 application, or DMP4047SSDQ-13 equivalent, key selection criteria include verified dual P-channel symmetry, -40V breakdown margin, RDS(on) performance at -4.5V gate drive, thermal resistance under 71°C/W (with copper pad), and AEC-Q101 qualification status for automotive-grade variants.
Technical Context
This device integrates two matched P-channel MOSFETs in a single SO-8 package with shared source terminals per channel (S1/G1/D1 and S2/G2/D2), enabling synchronous buck or dual low-side switch configurations without external isolation. Its gate threshold voltage (-1.0V to -3.0V) supports logic-level control from 3.3V/5V microcontrollers.
The MOSFET features fully characterized avalanche energy rating (EAS = 16.2mJ) and 100% production UIS testing, confirming ruggedness in inductive load switching. Dynamic parameters-including Qg = 21.5nC at -10V and tr/tf < 20ns/26ns-support high-frequency (>1MHz) operation in space-constrained power management designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | -40V - Supports input rails up to 36V nominal automotive or industrial systems with 10% derating margin. |
| RDS(on) | 45mΩ @ VGS = -10V - Enables ≤0.2W conduction loss at 6.5A, critical for thermally constrained PCB layouts. |
| ID Continuous | -6.5A @ TA = +25°C - Validated with 1-inch² copper pad; delivers full current without forced air or heatsink. |
| Qg | 21.5nC @ VGS = -10V - Determines gate driver current requirement (~2.15mA avg. at 100kHz switching). |
| RθJA | 71°C/W - Measured with enhanced 1-inch² copper; enables junction temperature prediction within ±5°C at 1W dissipation. |
| EAS | 16.2mJ - Specifies single-pulse inductive energy handling capability without failure, validated per JEDEC JESD24-11. |
| VGS(th) | -1.0V to -3.0V - Ensures turn-on compatibility with standard 3.3V GPIO while avoiding spurious conduction near 0V. |
Pinout & Package
Package: SO-8, surface-mount, lead-free, halogen-free "Green" molded plastic (UL 94V-0), 0.074g mass, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | Gate of Channel 1 | Controls conduction of first P-MOSFET; referenced to S1; requires negative gate drive relative to source. |
| 2 (S1) | Source of Channel 1 | Common return node for Channel 1; electrically isolated from S2 in internal layout but externally accessible. |
| 3 (D1) | Drain of Channel 1 | High-side or low-side switching node; bonded to exposed pad for thermal conduction in SO-8 footprint. |
| 4 (D2) | Drain of Channel 2 | Independent high-current output node; symmetrical to D1; supports interleaved or phase-split topologies. |
| 5 (S2) | Source of Channel 2 | Return path for Channel 2; separate from S1-enables independent source referencing or floating configurations. |
| 6 (G2) | Gate of Channel 2 | Independent control input; identical threshold and drive requirements as G1; no internal cross-coupling. |
| 7, 8 (Exposed Pad) | Thermal & Electrical Ground | Internally connected to both drains (D1/D2); must be soldered to PCB copper for thermal performance and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Dual matched P-channel topology | Enables compact dual-output or redundant power paths without discrete component pairing or matching tolerance concerns. |
| 100% UIS-tested avalanche ruggedness | Guarantees reliable operation in flyback, boost, and motor drive circuits with unclamped inductive transients. |
| Low Qgd/Qgs ratio (3.3nC/2.2nC) | Reduces Miller-induced shoot-through risk during hard-switching transitions in half-bridge configurations. |
| Body diode trr = 9.61ns | Minimizes reverse recovery losses in synchronous rectification or bidirectional DC-DC applications. |
| AEC-Q101 qualified variant available | DMP4047SSDQ (Q-suffix) meets automotive stress test requirements for under-hood and infotainment power modules. |
Applications
| Automotive LED Headlamp Driver | Industrial Dual-Output Buck Converter |
|---|---|
Use Scenario: Driving high-brightness LED strings in adaptive front lighting systems with independent left/right dimming control. IC Role / Device Role / Timing Role: Dual-channel high-side switch regulating current through two separate LED loads using PWM-controlled P-MOSFETs. Use Value: Eliminates need for two discrete SO-8 MOSFETs and associated layout area; RDS(on) matching ensures balanced current sharing across channels. |
Use Scenario: Generating isolated 5V and 3.3V rails from a 12V industrial supply in programmable logic controllers. IC Role / Device Role / Timing Role: Dual synchronous rectifier in interleaved buck stage, reducing output ripple and improving transient response. Use Value: Shared thermal pad lowers junction temperature rise by ~12°C vs. discrete devices, extending lifetime in sealed enclosures. |
| Laptop Backlight Inverter | USB-C Power Delivery Load Switch |
Use Scenario: Controlling CCFL or edge-lit LED backlight brightness via dual-phase current regulation in ultrabook displays. IC Role / Device Role / Timing Role: Dual low-side switch modulating current through parallel backlight strings with independent PWM inputs. Use Value: Fast 19.6ns rise time enables precise dimming resolution down to 0.1% duty cycle without visible flicker. |
Use Scenario: Enabling/disabling VBUS and VCONN paths in USB-C receptacles with overcurrent protection and soft-start. IC Role / Device Role / Timing Role: Dual-channel reverse-polarity load switch providing independent control of power and configuration channel lines. Use Value: -40V rating accommodates 20V PD3.1 peak voltages with safety margin; body diode forward voltage ≤ -1.2V limits conduction loss during hot-plug events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC3025LSDQ-13 | -30V VDS, 25mΩ RDS(on) @ -10V, lower voltage rating but 44% lower on-resistance | Suitable only for ≤24V systems; higher current density increases thermal sensitivity in high-ambient environments | Select when board space is constrained and input voltage never exceeds 28V; verify avalanche energy margin (EAS = 9.5mJ) is sufficient. |
| SI6926ADQ-T1-GE3 | -40V VDS, 52mΩ RDS(on) @ -10V, higher RDS(on) but wider gate threshold (-0.5V to -2.5V) | More tolerant of weak gate drive but dissipates ~16% more conduction loss at 6A | Prefer when interfacing with older 5V logic families or where tighter VGS(th) distribution improves yield in high-volume assembly. |
Compared with DMP4047SSDQ-13, DMC3025LSDQ-13 trades voltage headroom for lower conduction loss, while SI6926ADQ-T1-GE3 sacrifices on-resistance for broader gate threshold stability-making DMP4047SSDQ-13 the optimal balance for 36V-input automotive and industrial DC-DC designs requiring robust avalanche performance.

FAQ
Is DMP4047SSDQ-13 pin-compatible with DMP4047SSD-13?
Yes-DMP4047SSDQ-13 and DMP4047SSD-13 share identical SO-8 pinout, electrical specifications, and thermal characteristics. The "Q" suffix denotes AEC-Q101 qualification, including additional stress testing and PPAP documentation, but does not alter physical or functional compatibility.
What is the maximum safe operating temperature for DMP4047SSDQ-13 in continuous operation?
The absolute maximum junction temperature is +150°C, but continuous operation above +125°C requires derating per the RθJA curve. With the recommended 1-inch² copper pad, sustained 1.1W dissipation keeps TJ ≤ +125°C at +70°C ambient-verified in Diodes' thermal characterization report DS36353 Rev. 4-2.
Does DMP4047SSDQ-13 support gate driving from 3.3V microcontrollers?
Yes-its VGS(th) range (-1.0V to -3.0V) ensures reliable turn-on with 3.3V logic when configured as a high-side switch with source tied to VIN. At VGS = -3.3V, RDS(on) is typically 68mΩ, delivering -4.2A continuous current per channel at +25°C.
How is the exposed pad in SO-8 package electrically connected internally?
The exposed pad is internally bonded to both drain terminals (D1 and D2), forming a common thermal and electrical node. It must be soldered to a PCB copper pour connected to the system ground or drain net-no isolation or floating connection is permitted per Diodes' layout guidelines in DS36353 page 6.
