Product details
Overview
DMP2900UWQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET designed for automotive-grade load switching and power management. It features -20V VDSS, 750 mΩ RDS(ON) at VGS = -4.5V, -0.6A continuous drain current, AEC-Q101 qualification, and SOT323 packaging-enabling compact, reliable DC-DC converter and battery protection circuits.
For engineers reviewing the DMP2900UWQ datasheet, DMP2900UWQ pinout, DMP2900UWQ application, or DMP2900UWQ equivalent, key selection criteria include gate threshold voltage (-0.5 to -1.0 V), low-input capacitance (49 pF Ciss), fast switching (tD(on) = 16 ns), thermal resistance (272 °C/W), and AEC-Q101 compliance for automotive power rails.
Technical Context
This MOSFET operates in enhancement mode with a negative gate threshold (VGS(TH) = -0.5 to -1.0 V), enabling direct interface with 3.3V/5V logic-controlled high-side switches. Its low RDS(ON) at low |VGS| supports efficient operation in battery-powered systems where gate drive voltage is limited.
The device integrates ESD protection on the gate, exhibits low leakage (±2.0 μA IGSS, -100 nA IDSS), and delivers fast turn-off (tD(off) = 213 ns) with minimal reverse recovery charge (QRR = 1.8 nC), critical for synchronous rectification and PWM-controlled power paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20 V - Maximum drain-source blocking voltage for 12V automotive rail protection |
| RDS(ON) | 750 mΩ @ VGS = -4.5V - Enables <150 mW conduction loss at 430 mA load current |
| ID (TA = 25°C) | -0.6 A - Continuous current rating under standard PCB layout (2 oz Cu, 1″² pad) |
| Ciss | 49 pF - Low input capacitance reduces gate drive power and speeds up switching transitions |
| tD(on)/tF | 16 ns / 89 ns - Fast turn-on and fall time support >1 MHz PWM operation in compact converters |
| RθJA | 272 °C/W - Thermal performance defined per JEDEC JESD51-3 on FR-4 with recommended pad layout |
| Qg | 0.7 nC - Low total gate charge minimizes driver IC loading and gate resistor sizing |
Pinout & Package
Package: SOT323 - ultra-small surface-mount plastic package (2.15 mm × 2.10 mm × 0.95 mm), moisture sensitivity level 1, matte tin–annealed terminals, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control terminal | Accepts negative VGS to modulate channel; threshold range -0.5 to -1.0 V enables 3.3V logic compatibility |
| S (Source) | Reference node | Connected to higher potential (e.g., battery +); body diode anode faces source for reverse polarity protection |
| D (Drain) | Power output node | Switches load to ground; rated for -20V blocking and -0.6A steady-state current |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | VGS(TH) = -0.5 to -1.0 V allows full enhancement with 3.3V microcontroller GPIO without level shifting |
| Low RDS(ON) at low |VGS| | 1050 mΩ @ VGS = -2.5V ensures usable on-resistance even in 2.5V logic systems |
| ESD-protected gate | HBM rating ≥2 kV (per AEC-Q101 stress test) reduces risk of assembly damage and field failure |
| Fast switching with low Qgd | Qgd = 0.1 nC limits Miller plateau duration, improving controllability in high-frequency PWM |
| AEC-Q101 qualified | Validated for automotive temperature range (-55°C to +150°C) and PPAP-ready for Tier-1 production |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305U-7 | RDS(ON) = 48 mΩ @ VGS = -4.5V; higher current (−4.2A); SO-8 package | Requires larger board area and higher gate drive strength; unsuitable for space-constrained automotive modules | Select when higher current and lower RDS(ON) outweigh size and thermal constraints |
| AO3401 | RDS(ON) = 85 mΩ @ VGS = -4.5V; no AEC-Q101 qualification; SOT23 package | Lacks automotive qualification and fails PPAP documentation requirements for OEM programs | Acceptable only for non-automotive industrial or consumer designs with relaxed reliability mandates |
Compared with DMG2305U-7 and AO3401, DMP2900UWQ uniquely balances AEC-Q101 compliance, SOT323 footprint, and sub-1Ω RDS(ON) at low gate voltage-making it optimal for cost-sensitive, space-limited automotive load switches where qualification and thermal efficiency are jointly critical.

FAQ
What is the maximum safe operating junction temperature for DMP2900UWQ?
The absolute maximum junction temperature is +150°C, validated per AEC-Q101 stress testing. Under continuous operation at TA = +70°C with RθJA = 272°C/W and PD = 0.5 W, calculated TJ reaches ~206°C-so derating is required. Safe steady-state operation requires limiting power dissipation to ≤0.18 W at +70°C ambient to stay within 150°C TJ.
Can DMP2900UWQ be used in a high-side switch configuration with 3.3V GPIO control?
Yes. With VGS(TH) ranging from -0.5 V to -1.0 V, the device fully enhances when the gate is pulled to 0 V (logic low) and source is at 3.3 V-yielding VGS = -3.3 V. This provides strong inversion and ensures RDS(ON) ≤ 750 mΩ, making it suitable for direct 3.3V MCU-driven high-side switching.
Does DMP2900UWQ include integrated body diode functionality?
Yes. As a standard P-channel MOSFET, it contains an intrinsic parasitic body diode with cathode at source and anode at drain. The diode forward voltage is -1.2 V at -150 mA, verified per datasheet Figure 9. This enables reverse-current protection and freewheeling in inductive load circuits without external diodes.
Is the SOT323 package of DMP2900UWQ compatible with standard reflow profiles?
Yes. The SOT323 package is rated for moisture sensitivity level 1 (MSL-1) per J-STD-020, meaning it can be stored indefinitely at ≤30°C/85% RH and processed using standard Pb-free reflow profiles (peak 260°C). Its matte tin–annealed terminals meet MIL-STD-202 solderability requirements.
