Product details
Overview
DMP4047SSD 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; designed for high-efficiency DC-DC converters and backlighting power stages where compact dual-channel reverse-polarity switching is required.
For engineers reviewing the DMP4047SSD datasheet, DMP4047SSD pinout, DMP4047SSD application, or DMP4047SSD equivalent, key selection criteria include verified dual P-channel matching, SO-8 thermal performance under pulsed load, body diode recovery time (9.61ns), and AEC-Q101-compliant automotive-grade variant availability (DMP4047SSDQ).
Technical Context
This device integrates two matched P-channel MOSFETs in a single SO-8 package with shared source terminals (S1/S2) and independent gate/drain connections-enabling synchronous buck converter high-side/low-side control or dual independent load switches. Its low RDS(on) and fast switching (tD(off) = 34.9ns, Qgd = 3.3nC) support high-frequency operation up to 1MHz.
The MOSFET features 100% production-tested UIS capability (EAS = 16.2mJ), JEDEC-qualified reliability, and thermally optimized layout with RθJA = 71°C/W (with 1-inch² copper). Body diode forward voltage is -0.75V at -3.9A, supporting efficient freewheeling in buck and boost topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | -40V - supports 24V rail systems with 66% derating margin against transients |
| RDS(on) @ VGS = -10V | 45mΩ - enables ≤0.2W conduction loss at 6.5A in high-current paths |
| Continuous ID | -6.5A @ TA = +25°C - suitable for 10W–15W DC-DC output stages |
| Qg @ VGS = -10V | 21.5nC - determines gate drive power requirement for 500kHz–1MHz PWM |
| tr/tf | 19.6ns / 25.5ns - minimizes switching transition losses in hard-switched topologies |
| EAS | 16.2mJ - withstands unclamped inductive energy in relay or solenoid drive applications |
| TJ Range | -55°C to +150°C - qualified for extended industrial and under-hood automotive environments |
Pinout & Package

| 3 (D1) | Drain of Channel 1 | High-side switch output for Channel 1; electrically isolated from Channel 2 drain |
| 4 (S2) | Source of Channel 2 | Common source node for Channel 2; separate from S1 per datasheet pin diagram and equivalent circuit |
| 5 (G2) | Gate of Channel 2 | Independent control input for second P-MOSFET; decoupled gate drive enables asynchronous operation |

Applications
| LED Backlight Driver | USB-C Power Delivery Load Switch |
|---|---|
Use Scenario: Driving 4–6 series white LEDs in notebook display backlight with PWM dimming at 20kHz. IC Role / Device Role / Timing Role: Dual-channel P-MOSFET acts as high-side current sink and PWM-controlled current path selector. Use Value: 45mΩ RDS(on) limits conduction loss to <0.19W per channel at 6.5A peak, enabling >92% efficiency at 12V input. | Use Scenario: Enabling/disabling 20V/5A USB-C PD power path with reverse-polarity protection and hot-swap sequencing. IC Role / Device Role / Timing Role: Independent gate control allows staggered turn-on to limit inrush; body diode blocks reverse current during fault. Use Value: 9.61ns trr and -0.75V VSD minimize reverse recovery loss and voltage overshoot during load disconnect. |
| Industrial 24V Buck Converter | Automotive Cabin Lighting Control |
Use Scenario: 24V-to-5V/3A synchronous buck regulator in PLC I/O module with space-constrained PCB layout. IC Role / Device Role / Timing Role: Dual P-MOSFET replaces discrete high-side/low-side N-MOSFET + driver, simplifying gate drive design. Use Value: SO-8 footprint with exposed pad achieves 71°C/W θJA, maintaining TJ < 110°C at full load with 2oz copper. | Use Scenario: Dimmable 12V LED lighting control in automotive door panels with PWM and analog dimming inputs. IC Role / Device Role / Timing Role: One channel handles main LED string; second channel controls auxiliary indicator or status LED. Use Value: AEC-Q101-qualified variant (DMP4047SSDQ) ensures compliance with automotive thermal cycling (-40°C to +125°C) and ESD requirements. |
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 |
|---|---|---|---|
| DMC2038LSD-7 | Lower VDS (-20V), higher RDS(on) (60mΩ @ -4.5V), same SO-8 package | Optimized for 5V–12V logic-level systems; unsuitable for 24V bus transients | Select when gate drive is limited to -4.5V and system voltage ≤15V; verify avalanche rating (EAS = 8.5mJ) for inductive loads |
| Si7941DP-T1-GE3 | Higher VDS (-60V), lower RDS(on) (32mΩ @ -10V), larger PowerPAK SO-8 package | Requires modified PCB layout due to different thermal pad geometry and pinout | Choose for 48V systems or where lower conduction loss outweighs SO-8 footprint compatibility |
Compared with DMP4047SSD, DMC2038LSD-7 trades off voltage rating and ruggedness for tighter gate-threshold control at low VGS, while Si7941DP-T1-GE3 delivers superior RDS(on) and transient margin but demands layout revision and higher gate charge drive (Qg = 28nC).

FAQ
What is the maximum safe operating junction temperature for DMP4047SSD?
The absolute maximum junction temperature is +150°C per datasheet Section "Maximum Ratings." Derating begins at +70°C ambient for continuous operation, and thermal design must ensure TJ remains below this limit under worst-case power dissipation (1.8W with 1-inch² copper). Transient thermal resistance data (Figure 9) supports short-pulse operation up to 26A.
Can DMP4047SSD be used in a synchronous buck converter as both high-side and low-side switches?
No - DMP4047SSD contains two P-channel MOSFETs only, making it unsuitable as a low-side switch in standard synchronous buck topology (which requires an N-channel for efficient low-side conduction). It can serve as dual high-side switches or independent load switches, but not as complementary high/low pair without external N-MOSFETs.
Is the exposed thermal pad electrically isolated or connected internally?
The exposed pad (Pins 7–8) is internally connected to both D1 and D2 drains per the mechanical drawing and package outline. It must be soldered to a PCB copper pour tied to the drain net for optimal thermal performance and electrical integrity - floating or grounded pads will compromise thermal resistance and may cause reliability issues.
Does DMP4047SSD meet AEC-Q101 requirements for automotive use?
The base DMP4047SSD is JEDEC-qualified and built in IATF 16949-certified facilities, but only the automotive-grade variant DMP4047SSDQ is fully AEC-Q101 qualified and PPAP-capable. For automotive applications, Diodes explicitly directs users to the Q-suffix part and its dedicated datasheet - the standard part lacks formal AEC-Q101 test reports and change-control documentation.
