Product details
Overview
DMP2900UWQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET designed for automotive-grade load switching and DC-DC converter power management. It features -20V VDSS, 750mΩ RDS(ON) @ VGS = -4.5V, -0.6A continuous drain current at +25°C, AEC-Q101 qualification, and SOT323 packaging-enabling compact, reliable high-side switching in space-constrained automotive modules.
For engineers reviewing the DMP2900UWQ datasheet, DMP2900UWQ pinout, DMP2900UWQ application, or DMP2900UWQ equivalent, key selection criteria include gate threshold voltage (-0.5V to -1.0V), low-input capacitance (49pF Ciss), fast switching (tD(on) = 16ns), thermal resistance (272°C/W with recommended layout), and AEC-Q101 PPAP support for automotive production environments.
Technical Context
This device operates as a high-side load switch in 12V automotive systems, leveraging its low VGS(TH) to enable direct control from 3.3V/5V logic without level shifting. Its P-channel topology eliminates external bootstrap circuitry required by N-channel alternatives.
The MOSFET integrates ESD protection on the gate and exhibits low leakage (<±2.0μA IGSS, <−100nA IDSS) across −55°C to +150°C, supporting robust operation in under-hood environments where ambient temperature swings and electrical transients are common.
Key Specifications

|---|---|
| VDSS | −20V: Maximum blocking voltage for 12V automotive rail protection and reverse-polarity safeguarding |
| RDS(ON) | 750mΩ @ VGS = −4.5V: Enables ≤270mW conduction loss at 0.6A, critical for thermally constrained PCB layouts |
| ID (continuous) | −0.6A @ TA = +25°C: Supports moderate-power loads such as sensors, actuators, and infotainment peripherals |
| Ciss | 49pF: Reduces gate drive power and enables fast turn-on with minimal overshoot in low-current control paths |
| tD(on) | 16ns: Allows precise timing control in PWM-driven power rails and fault-responsive shutdown circuits |
| TJ range | −55°C to +150°C: Validated for engine bay, transmission control, and ADAS module deployment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel automotive load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2011UFD-7 | N-channel, −20V, 110mΩ @ VGS = −4.5V, requires high-side driver or bootstrap | Better RDS(ON) but adds complexity in high-side configuration; unsuitable for direct GPIO control | Select only when board space allows driver IC and layout supports floating gate drive |
| AO3401 | P-channel, −30V, 85mΩ @ VGS = −10V, not AEC-Q101 qualified, higher VGS(TH) (−0.7V to −1.3V) | Lacks automotive qualification and PPAP support; higher gate threshold increases risk of partial turn-on at 3.3V logic | Acceptable for non-safety-critical consumer or industrial prototypes, not for production automotive use |
Compared with DMN2011UFD-7 and AO3401, the DMP2900UWQ uniquely combines AEC-Q101 qualification, low −0.5V to −1.0V gate threshold for 3.3V logic compatibility, and SOT323 footprint-making it the only drop-in solution for space-constrained, safety-compliant automotive high-side switching without added driver circuitry.

FAQ
What is the maximum continuous drain current for DMP2900UWQ at +70°C ambient?
The DMP2900UWQ supports −0.5A continuous drain current at TA = +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the SOT323 package on standard FR-4 PCB with 2oz copper and minimum pad layout, ensuring safe operation without forced airflow or heatsinking.
Does DMP2900UWQ require a gate resistor for ESD protection?
No external gate resistor is required for ESD protection-the device integrates gate oxide protection rated to ≥2kV HBM per AEC-Q101. However, a small series resistor (10–100Ω) is recommended to dampen ringing during fast switching in high-di/dt environments, especially in long PCB traces or noisy automotive harnesses.
Can DMP2900UWQ be used in reverse-voltage protection circuits?
Yes-the DMP2900UWQ's P-channel structure and −20V VDSS rating make it suitable for reverse-polarity protection in 12V automotive systems. When placed in the high-side path with source tied to battery+, the body diode blocks reverse current, and the MOSFET conducts forward current with low RDS(ON) when properly biased.
Is the SOT323 package of DMP2900UWQ compatible with reflow soldering per J-STD-020?
Yes-the SOT323 package has Moisture Sensitivity Level 1 per J-STD-020, meaning it is exempt from floor life limitations and can be subjected to standard Pb-free reflow profiles (peak 260°C) without baking. The matte tin annealed finish ensures reliable solderability per MIL-STD-202, Method 208.
