Product details
Overview
DMP3056LSSQ-13 from Diodes Incorporated is a single P-channel enhancement-mode MOSFET rated for -30V VDSS, 45mΩ RDS(ON) at VGS = -10V, and -4.9A continuous drain current at TA = +25°C. It is AEC-Q101 qualified, PPAP-capable, and designed for automotive DC-DC converters and power management functions requiring robust UIS performance and low gate threshold voltage.
For engineers reviewing the DMP3056LSSQ-13 datasheet, DMP3056LSSQ-13 pinout, DMP3056LSSQ-13 application, or DMP3056LSSQ-13 equivalent, this part supports high-reliability automotive power switching with verified 100% unclamped inductive switching (UIS), low input capacitance (969pF), fast turn-off delay (43ns), and IATF 16949-manufactured traceability.
Technical Context
This P-channel MOSFET operates in enhancement mode with a gate threshold voltage range of -1.0V to -2.1V, enabling direct logic-level drive from 3.3V/5V controllers. Its low RDS(ON) and 102pF Crss support efficient synchronous rectification and high-frequency switching up to 1MHz.
The device integrates a body diode with tRR = 13.6ns and QRR = 3.4nC, optimized for flyback and buck converter freewheeling paths. Thermal resistance RθJA is 77°C/W (2oz copper board), supporting 1.6W steady-state dissipation at +25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - Withstands reverse drain-source voltage up to 30V in automotive load-dump or reverse-battery conditions. |
| RDS(ON) | 45mΩ @ VGS = -10V - Enables <150mW conduction loss at 5.8A, suitable for compact 12V automotive power rails. |
| ID (continuous) | -4.9A @ TA = +25°C - Supports mid-power switching in infotainment power supplies and LED backlight drivers. |
| Qg | 17.3nC @ VGS = -10V - Low gate charge reduces driver IC loading and enables efficient PWM control at >500kHz. |
| Ciss | 969pF @ VDS = -15V - Minimizes capacitive coupling noise and improves EMI behavior in high-speed switching nodes. |
| tRR | 13.6ns - Fast body diode recovery reduces switching losses and voltage overshoot in discontinuous conduction mode. |
| EAS | 15mJ - Rated avalanche energy ensures survivability during transient overcurrent events without derating. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3056LSD-13 | Same RDS(ON) (45mΩ @ -10V) but N-channel, requires high-side gate driver; 10% lower Ciss. | Suitable only where bootstrap or charge-pump driver is available; not drop-in for high-side logic-level use. | Select if system already uses N-channel high-side drivers and needs marginally faster switching. |
| IPD250N03L3-13 | Lower RDS(ON) (2.5mΩ), higher ID (250A), TO-252 package; no AEC-Q101 qualification. | Requires PCB redesign for DPAK footprint and lacks PPAP documentation for automotive Tier-1 programs. | Choose only for non-automotive industrial applications needing ultra-low RDS(ON) and higher current capacity. |
Compared with DMN3056LSD-13 and IPD250N03L3-13, DMP3056LSSQ-13 uniquely delivers AEC-Q101 compliance, SO-8 logic-level drivability, and production-tested UIS in a single package-making it the only qualified option for safety-critical automotive power switches without gate driver overhead.

FAQ
Is DMP3056LSSQ-13 suitable for high-side switching with 3.3V GPIO control?
Yes. Its gate threshold voltage range of -1.0V to -2.1V ensures full enhancement when driven by 3.3V logic, delivering ≤45mΩ RDS(ON) without external level shifting. Verified operation confirmed at VGS = -3.3V in datasheet Figure 2 transfer curves.
What is the maximum safe operating frequency for DMP3056LSSQ-13 in a buck converter?
Based on its 17.3nC total gate charge and 43ns turn-off delay, DMP3056LSSQ-13 supports stable operation up to 1MHz in hard-switched buck topologies. Layout-dependent parasitic inductance may limit practical frequency to 600–800kHz for optimal EMI and efficiency.
Does DMP3056LSSQ-13 require a heatsink in typical automotive applications?
No external heatsink is required for continuous operation below 1.0W dissipation. At 1.6W (TA = +25°C), its RθJA = 77°C/W yields ~123°C junction rise-within the -55°C to +150°C rating-provided the PCB uses 2oz copper with thermal vias to inner ground planes.
How does the 100% UIS test impact field reliability in automotive systems?
The production UIS test subjects every unit to -17A avalanche current and 15mJ energy, verifying robustness against real-world inductive transients like relay coil de-energization or motor stall events. This eliminates infant mortality failures in safety-critical power stages.
