Product details
Overview
DMP1070UQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -12V VDSS, 31mΩ RDS(ON) @ VGS = -4.5V, and -5.4A continuous drain current at +25°C. It serves as a high-efficiency power switch in low-voltage DC-DC converters and analog switching circuits.
For engineers reviewing the DMP1070UQ datasheet, DMP1070UQ pinout, DMP1070UQ application, or DMP1070UQ equivalent, key selection criteria include its AEC-Q101 qualification, low gate charge (11.5nC), fast turn-off fall time (950ns), and ESD-protected gate structure - all critical for automotive power management and compact load-switch designs.
Technical Context
This MOSFET employs a trench-gate process to achieve low RDS(ON) while maintaining controlled gate charge (QG = 11.5nC) and low output capacitance (Coss = 123pF). Its -1.0V typical VGS(TH) enables reliable turn-on with standard logic-level drive down to -2.5V.
The integrated gate protection diode and ESD-hardened structure support robust operation in noisy automotive environments. Thermal resistance of 89°C/W (with 1-inch2 copper pad) allows sustained -4.3A operation at +70°C ambient without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -12V - supports 12V rail switching and reverse-polarity protection in automotive body electronics |
| RDS(ON) | 31mΩ @ VGS = -4.5V - enables <150mW conduction loss at 4A, critical for thermally constrained SOT23 layouts |
| ID (TA = +25°C) | -5.4A - maximum steady-state current with FR-4 board and minimum pad layout |
| QG | 11.5nC - reduces gate drive power and enables efficient PWM control up to ~1MHz |
| tF | 950ns - ensures fast discharge of load capacitance in hot-swap and sequencing applications |
| Ciss | 143pF - limits Miller-induced shoot-through risk in half-bridge configurations |
| TJ Range | -55°C to +150°C - qualified for under-hood automotive use per AEC-Q101 |
Pinout & Package
Package: SOT23 - surface-mount, 3-terminal plastic case (0.915mm width, 2.90mm length), moisture sensitivity level 1, RoHS-compliant matte tin finish over copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for P-channel device | Internally connected to substrate; primary thermal path and reference for gate drive |
| 2 (Gate) | Control electrode for channel conduction | ESD-protected input requiring ≤±8V drive; threshold centered at -0.7V |
| 3 (Drain) | High-side switched output node | Connected to load; handles full -12V blocking and pulsed -33A surge currents |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at logic-level drive | 31mΩ @ -4.5V enables direct interface with 5V/3.3V microcontrollers without level-shifting |
| Fast switching with low Qgd/Qg ratio | Qgd = 2.9nC / Qg = 11.5nC = 0.25 - suppresses Miller plateau duration and improves hard-switching stability |
| Integrated gate ESD protection | HBM rating >2kV (per AEC-Q101 test flow) - eliminates need for external gate resistors or TVS in most board-level implementations |
| AEC-Q101 qualification | Validated for automotive power management including engine control modules and body control units |
Applications
| Load Switch for 12V Automotive Modules | USB Port Power Control |
|---|---|
Use Scenario: Isolating infotainment head unit power during ignition-off to prevent battery drain. IC Role / Device Role / Timing Role: High-side P-channel switch controlling 12V supply to downstream LDOs and microcontrollers. Use Value: 31mΩ RDS(ON) limits dropout to <125mV at 4A, preserving system voltage margin while enabling fast turn-off (tF = 950ns) for clean power sequencing. | Use Scenario: Enabling/disabling VBUS power to USB peripherals in portable diagnostic tools. IC Role / Device Role / Timing Role: Low-voltage analog switch managing 5V rail with logic-level enable from MCU GPIO. Use Value: -1.0V VGS(TH) ensures full enhancement at 3.3V logic drive; 143pF Ciss minimizes capacitive loading on host controller pins. |

IC Role / Device Role / Timing Role: In-line series switch placed between battery and input capacitor. Use Value: -12V BVDSS provides 20% margin above nominal 12V system; body diode forward voltage (VSD = -0.6V) limits fault dissipation during reverse event. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG1012T | RDS(ON) = 45mΩ @ -4.5V; higher QG (14nC); same SOT23 package | Lower efficiency at high current; slower switching due to higher gate charge | Preferred where cost sensitivity outweighs 10–15% conduction loss penalty |
| SI2301DDS | RDS(ON) = 115mΩ @ -4.5V; lower ID (-2.7A); non-AEC-Q101 | Not suitable for automotive; limited to consumer-grade 5V load switches | Select only for non-automotive, space-constrained 3.3V systems with <2A loads |
Compared with DMG1012T and SI2301DDS, DMP1070UQ delivers superior power density (31mΩ in SOT23), automotive qualification, and optimized gate charge for high-frequency switching - making it the preferred choice for AEC-Q101-compliant 12V power rails and fast-turnoff sequencing.

FAQ
Is DMP1070UQ suitable for hot-swap applications?
Yes. Its 950ns turn-off fall time, 33A pulsed drain rating, and ESD-protected gate support controlled inrush limiting in hot-swap circuits. The -12V VDSS and low RDS(ON) ensure minimal voltage drop and thermal stress during insertion transients, provided PCB layout includes adequate copper area for thermal dissipation.
What is the maximum safe operating temperature for continuous operation?
The junction temperature must not exceed +150°C. With a thermal resistance of 89°C/W (on 1-inch² copper), the device supports continuous -4.3A at +70°C ambient. Derating is required above that ambient; for example, at +100°C ambient, max continuous current drops to approximately -2.7A to maintain TJ ≤ 150°C.
Does DMP1070UQ require an external gate resistor?
No external gate resistor is required for basic switching. The internal gate resistance is 401Ω, and the ESD-protected structure tolerates direct drive from 3.3V/5V GPIOs. However, a small series resistor (≤10Ω) is recommended in high-noise automotive environments to damp ringing and reduce EMI during fast transitions.
Can DMP1070UQ be used in parallel with identical devices?
Parallel operation is not recommended. The -0.3V to -1.0V VGS(TH) spread and positive RDS(ON) temperature coefficient create uneven current sharing at low VGS. For higher current needs, select a single larger-package MOSFET (e.g., SO-8 or PowerDI3333) with tighter threshold matching and lower thermal resistance.
