Product details
Overview
DMP3050LSS-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SO-8 package, rated for -30V VDS, 45 mΩ RDS(on) at VGS = -10V, and -4.8A continuous drain current at 25°C - optimized for high-efficiency DC-DC converters and backlight power stages.
For engineers reviewing the DMP3050LSS-13 datasheet, DMP3050LSS-13 pinout, DMP3050LSS-13 application, or DMP3050LSS-13 equivalent, key selection criteria include verified RDS(on) vs. gate drive voltage (-4.5V/-10V), AEC-Q101 qualification, SO-8 thermal performance (RθJA = 73°C/W), and body diode recovery characteristics (trr = 14 ns).
Technical Context
This MOSFET operates as a synchronous rectifier or high-side switch in buck and boost topologies, leveraging its low 620 pF input capacitance (Ciss) and 10.5 nC total gate charge at -10V to minimize switching losses. Its -2.0V maximum gate threshold ensures robust turn-on with standard logic-level gate drivers.
The device integrates a fast-recovery body diode (Qrr = 11 nC, trr = 14 ns) and maintains stable RDS(on) across -55°C to 150°C junction temperature, supported by 73°C/W steady-state thermal resistance on FR-4 PCB with 1-inch² copper pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -30 V - Maximum blocking voltage for 24V rail and automotive load-switch applications |
| RDS(on) | 45 mΩ @ VGS = -10V - Enables ≤0.22 W conduction loss at 3.3A DC load |
| ID (cont) | -4.8 A @ TA = 25°C - Sustains full-rated current without derating on standard PCB layout |
| Qg | 10.5 nC @ VGS = -10V - Determines gate driver strength requirement for <20 ns switching transitions |
| trr | 14 ns - Limits reverse recovery energy in synchronous rectification, reducing shoot-through risk |
| RθJA | 73 °C/W - Predicts ~110°C junction rise at 1.7W dissipation, guiding heatsinking decisions |
| VGS(th) | -1.0 to -2.0 V - Ensures reliable turn-on with 3.3V or 5V microcontroller GPIO |
Pinout & Package
Package: SO-8 (Surface-Mount, 8-pin, 4.9 mm × 6.0 mm footprint, 1.75 mm height), RoHS-compliant matte tin-plated leads, moisture sensitivity level 1.

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG3415L-7 | RDS(on) = 50 mΩ @ -4.5V; SO-8; no AEC-Q101 qualification | Targeted at commercial-grade consumer power management, not automotive | Select when AEC-Q101 is unnecessary and cost sensitivity outweighs thermal margin |
| SI3457DV-T1-GE3 | RDS(on) = 60 mΩ @ -4.5V; SC-70-6 package; lower ID = -2.5A | Designed for space-constrained portable electronics, not high-current power stages | Choose only for ultra-low-profile designs where current demand stays below 2A |
Compared with DMG3415L-7 and SI3457DV-T1-GE3, DMP3050LSS-13 delivers superior thermal capability (1.7W PD), automotive qualification, and higher current handling - making it the sole choice for 3–5A industrial or automotive power switches requiring long-term reliability.

FAQ
What is the maximum safe gate-source voltage for DMP3050LSS-13 in automotive applications?
The absolute maximum VGS is ±25 V per datasheet, but AEC-Q101 qualification restricts recommended operation to ±20 V to ensure long-term reliability under temperature cycling and humidity stress. Exceeding ±20 V risks gate oxide degradation in automotive-grade use cases.
Can DMP3050LSS-13 be used as a synchronous rectifier in a 500 kHz flyback converter?
Yes - its 10.5 nC Qg, 620 pF Ciss, and 14 ns trr support efficient operation at 500 kHz. Gate drive must deliver ≥20 mA peak current to achieve <20 ns rise/fall times, and PCB layout must minimize source inductance to avoid oscillation.
Does the SO-8 package include an exposed drain pad, and how should it be connected?
Yes - pins 5–8 form an internal drain-connected copper paddle on the bottom side. It must be soldered to a large PCB copper pour (≥1 inch²) for thermal conduction and electrical connection to the drain net, per Diodes' AP02002 layout guidelines.
How does RDS(on) change over temperature, and what is its value at 125°C?
RDS(on) increases linearly with junction temperature. At VGS = -10V and TJ = 125°C, RDS(on) is approximately 1.5× the 25°C value - i.e., ~67.5 mΩ - based on Figure 6's normalized curve and 150°C max rating.
