Product details
Overview
DMP4025LSD-13 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SO-8 package, rated for -40V VDSS, 25 mΩ RDS(ON) @ VGS = -10V, and -7.6A continuous drain current at TA = +25°C. It serves as a high-efficiency synchronous rectifier or load switch in DC-DC converters and motor control H-bridge legs.
For engineers reviewing the DMP4025LSD-13 datasheet, DMP4025LSD-13 pinout, DMP4025LSD-13 application, or DMP4025LSD-13 equivalent, key selection criteria include verified dual P-channel topology, SO-8 thermal performance (RθJA = 58°C/W), body diode forward voltage (-0.7V @ -1A), and AEC-Q qualified automotive variant availability (DMP4025LSDQ).
Technical Context
This dual MOSFET integrates two matched P-channel silicon die in a single SO-8 package with shared source terminals and independent gate/drain connections. Its symmetric layout supports bidirectional switching in half-bridge configurations and enables complementary drive without external level-shifting.
It features low gate charge (Qg = 33.7 nC @ VGS = -10V) and fast switching (tF = 30.9 ns), optimized for 300 kHz–1 MHz DC-DC operation. The device meets JEDEC reliability standards and includes 100% production UIS testing for ruggedness in inductive load switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40 V - Maximum blocking voltage for high-side P-channel switching in 24V industrial rails |
| RDS(ON) | 25 mΩ @ VGS = -10V - Enables ≤0.57 W conduction loss at -3A, critical for thermally constrained PCBs |
| ID (cont) | -7.6 A @ TA = +25°C - Supports sustained current in printer feed motors and backlight LED strings |
| Qg | 33.7 nC @ VGS = -10V - Reduces gate driver power demand and enables efficient 1 MHz PWM control |
| VSD | -0.7 V @ IS = -1A - Low body diode drop improves reverse-current efficiency in synchronous buck freewheeling |
| RθJA | 58 °C/W - Validated on 25 mm × 25 mm × 1.6 mm FR4 with 1 oz copper, enabling 2.14 W dissipation in still air |
| Ciss | 1640 pF - Predictable input capacitance for stable gate drive loop design and EMI filtering |
Pinout & Package

| 1, 2, 3 | Source (Channel 1) | Common source connection for first P-MOSFET; tied to ground or low-side reference in half-bridge |
| 4 | Gate (Channel 1) | Independent gate control for first channel; requires negative bias relative to source for turn-on |
| 5, 6, 7 | Source (Channel 2) | Common source connection for second P-MOSFET; electrically isolated from Channel 1 source in layout |
| 8 | Gate (Channel 2) | Independent gate control for second channel; enables dual-channel timing control or redundancy |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) @ -4.5V | 45 mΩ - Enables direct logic-level drive from 3.3V/5V microcontrollers without gate boosters |
| 100% UIS tested | 23 A / 79 mJ avalanche rating - Guarantees robustness against inductive kickback in motor and solenoid loads |
| Fast switching | tF = 30.9 ns - Minimizes dead-time losses and improves light-load efficiency in synchronous buck regulators |
| Thermal performance | RθJL = 51 °C/W - Efficient heat transfer to PCB copper pour via drain leads, supporting compact thermal design |
| Automotive qualification | AEC-Q200 compliant variant (DMP4025LSDQ) available - Enables drop-in use in automotive body electronics and ADAS power stages |
Applications
| Motor Control | DC-DC Converters |

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 | RDS(ON) = 38 mΩ @ -4.5V; lower Qg (19.5 nC); same SO-8 package | Better suited for ultra-low-power 3.3V logic-driven systems where gate drive loss dominates | Select when prioritizing gate drive efficiency over conduction loss at >4A loads |
| SI7862DN-T1-GE3 | RDS(ON) = 22 mΩ @ -10V; higher ID (−9.5A); different pinout (drain/source swapped) | Requires PCB layout revision due to non-compatible pin mapping; superior thermal RθJA (45°C/W) | Choose only if redesigning layout and requiring >7.6A continuous current with improved thermal headroom |
Compared with DMP4025LSD-13, DMC2038LSD-7 trades higher conduction loss for lower gate energy, while SI7862DN-T1-GE3 delivers lower RDS(ON) but mandates board rework-making DMP4025LSD-13 optimal for cost-sensitive, drop-in SO-8 upgrades in existing 24V industrial power stages.

FAQ
Is DMP4025LSD-13 suitable for automotive applications?
Yes-the DMP4025LSDQ variant is AEC-Q200 qualified and automotive-grade, while the DMP4025LSD-13 shares identical electrical and thermal specifications. It is commonly used in body electronics such as seat control modules and lighting drivers, provided system-level validation confirms environmental stress compliance.
What is the maximum safe operating temperature for DMP4025LSD-13?
The junction temperature must not exceed +150°C. With RθJA = 58°C/W and PD = 2.14 W, ambient temperature must stay below +31°C for full-power operation on standard FR4. Derating to 1.25 W above +70°C ambient is required per datasheet Note 5.
Can DMP4025LSD-13 be used in a single-channel configuration?
Yes-either channel can operate independently. Pins 1–3 and 4 form one P-MOSFET; pins 5–7 and 8 form the second. Unused channel gates must be tied to respective sources to prevent floating, and drain terminals remain isolated unless externally connected.
Does DMP4025LSD-13 require a gate resistor for stability?
A gate resistor (typically 10–47 Ω) is recommended to dampen ringing caused by Lg/Ciss resonance and limit peak gate current. The device's Rg = 6.43 Ω internal gate resistance helps but does not eliminate need for external series resistance in high-speed switching layouts.
