Product details
Overview
DMP31D7LV-7 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SOT563 package, rated for -30V VDSS, 0.9Ω RDS(ON) at VGS = -10V, and -0.62A continuous drain current at +25°C - designed for compact, high-efficiency DC-DC converters and motor control circuits.
For engineers reviewing the DMP31D7LV-7 datasheet, DMP31D7LV-7 pinout, DMP31D7LV-7 application, or DMP31D7LV-7 equivalent, key selection criteria include dual-channel P-MOSFET topology, low gate charge (0.36nC @ VGS = -4.5V), ESD-protected gate, and thermal resistance of 153°C/W with enhanced copper pad layout.
Technical Context
This dual P-channel MOSFET integrates two independent enhancement-mode transistors sharing no internal connection - each with verified VGS(TH) of -1.0 to -2.6V and body diode forward voltage of -0.8 to -1.2V at -0.23A. Gate drive requires negative bias relative to source, supporting high-side switching in buck regulators and H-bridge half-bridges.
Its dynamic parameters include Ciss = 19pF, Coss = 16pF, and Crss = 3pF at VDS = -15V, enabling fast turn-on (tD(ON) = 30ns) and turn-off (tD(OFF) = 28ns) with 1Ω gate resistance - critical for minimizing switching losses in 500kHz–1MHz power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - supports rail-to-rail operation in 24V industrial bus and 12V automotive subsystems without avalanche stress. |
| RDS(ON) | 0.9Ω @ VGS = -10V - delivers ≤0.32W conduction loss at -0.42A, enabling thermally constrained PCB layouts. |
| ID (continuous) | -0.62A @ TA = +25°C - sufficient for low-power load switches and sensor biasing in space-constrained IoT nodes. |
| Qg | 0.36nC @ VGS = -4.5V - reduces gate driver power demand and enables efficient PWM control from microcontroller GPIOs. |
| RθJA | 153°C/W - achievable with 1-inch² 2oz copper pad; allows 0.5W dissipation up to +70°C ambient without forced cooling. |
| Ciss | 19pF - minimizes Miller effect during switching transitions, improving noise immunity in mixed-signal environments. |
| VGS(TH) | -1.0 to -2.6V - ensures reliable turn-on with standard logic-level negative gate drivers (e.g., TC4427 inverting output). |
Pinout & Package
Package: SOT563 - ultra-compact 6-pin surface-mount package (1.60 × 1.60 × 0.60 mm), molded green compound, matte tin-plated copper leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1 | Drain of Channel 1 | High-current output node; electrically isolated from D2; connects to switched load or power rail. |
| S1 | Source of Channel 1 | Reference node for Channel 1; ties to local ground or higher potential depending on high-side configuration. |
| G1 | Gate of Channel 1 | Control input requiring negative VGS; ESD-protected; driven by dedicated gate driver or logic-level inverter. |
| D2 | Drain of Channel 2 | Independent high-current output; no internal connection to D1 - supports dual-load or complementary switching. |
| S2 | Source of Channel 2 | Reference node for Channel 2; may be tied to same or separate potential as S1 per circuit topology. |
| G2 | Gate of Channel 2 | Independent control input; identical electrical characteristics to G1; enables synchronized or staggered switching. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at low VGS | 1.7Ω @ VGS = -4.5V - enables direct drive from 5V/3.3V logic with minimal external components. |
| ESD-protected gate | HBM rating ≥2kV - eliminates need for external gate protection diodes in board-level ESD zones. |
| Low input capacitance | Ciss = 19pF - reduces gate drive energy and improves switching efficiency above 500kHz. |
| Thermally optimized package | RθJA = 153°C/W with 1″² copper - supports >0.5W operation in sealed enclosures without heatsinks. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) - meets IPC-1752A reporting requirements. |
Applications
| Brushless DC Motor Driver | USB-C Power Delivery Load Switch |
|---|---|

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 |
|---|---|---|---|
| DMN31D7L-7 | Single-channel P-MOSFET, same RDS(ON) and VDSS, but no second channel; SOT23-6 package. | Requires two devices for dual-load control; larger total footprint (2 × 2.9 × 1.3 mm vs. 1 × 1.6 × 1.6 mm). | Select when only one switched rail is needed or when board layout favors discrete placement over dual integration. |
| AOB3100P | 30V dual P-MOSFET in TSOP-6; RDS(ON) = 1.2Ω @ -4.5V; Qg = 0.65nC - higher gate charge and on-resistance. | Higher conduction loss (≥0.25W @ 0.4A) and slower switching limit use in >1MHz DC-DC topologies. | Select only if TSOP-6 reflow compatibility or legacy footprint reuse is required; not recommended for new high-efficiency designs. |
Compared with DMN31D7L-7 and AOB3100P, DMP31D7LV-7 uniquely delivers dual-channel functionality in the smallest footprint (SOT563), lowest gate charge (0.36nC), and tightest VGS(TH) distribution - making it optimal for space- and efficiency-critical dual-rail power management.

FAQ
What is the maximum safe operating temperature for DMP31D7LV-7?
The DMP31D7LV-7 has an operating junction temperature range of -55°C to +150°C. With its RθJA of 153°C/W and 0.8W power dissipation capability on a 1-inch² copper pad, it sustains continuous operation up to +70°C ambient while maintaining TJ ≤ 120°C - well within safe silicon limits for long-term reliability.
Can DMP31D7LV-7 be used in high-side switch configurations without a charge pump?
Yes - as a P-channel MOSFET, DMP31D7LV-7 operates as a high-side switch with gate driven negative relative to source. No charge pump is required; a simple inverting driver (e.g., TC4427) or logic-level shifter suffices to achieve VGS ≤ -4.5V for full enhancement, leveraging its -2.6V maximum VGS(TH).
Is there an automotive-grade version of this part?
Yes - the DMP31D7LVQ is the AEC-Q101 qualified automotive variant of this device, sharing identical electrical specifications and SOT563 packaging but subjected to extended temperature cycling, HTOL, and ESD testing per automotive qualification standards.
How does the ESD protection on the gate affect layout practices?
The integrated ESD protection diode (HBM ≥2kV) eliminates the need for external gate resistors or TVS diodes in most applications. Layout should still maintain short, direct gate traces to minimize inductance, avoid routing near noisy signals, and ensure solid ground return paths - especially critical for fast-switching (>500kHz) operation.
