Product details
Overview
DMP2900UTQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET designed for low-voltage load switching in space-constrained automotive and portable electronics. It delivers RDS(ON) = 700 mΩ at VGS = −4.5 V, supports −0.5 A continuous drain current at +25°C, and features AEC-Q101 qualification, ESD-protected gate, and SOT523 package.
For engineers reviewing the DMP2900UTQ datasheet, DMP2900UTQ pinout, DMP2900UTQ application, or DMP2900UTQ equivalent, key selection criteria include low gate threshold (−0.5 to −1.0 V), normalized RDS(ON) stability over −55°C to +150°C, fast turn-off delay (213 ns), and IATF16949-certified manufacturing traceability.
Technical Context
This MOSFET operates as a single-polarity high-side switch with gate-controlled conduction between source and drain. Its low VGS(TH) enables direct interface with 1.8 V/2.5 V logic, while ESD protection (HBM > 2 kV) ensures robustness in assembly and field operation.
The device uses a planar trench-gate structure optimized for RDS(ON)/Qg trade-off: Ciss = 49 pF and Qg = 0.7 nC support efficient switching in DC-DC converter synchronous rectification and battery-isolation circuits at frequencies up to 1 MHz.

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 |
|---|---|---|---|
| DMN2016LFG-7 | RDS(ON) = 380 mΩ @ VGS = −4.5 V; larger SOT-23 package (2.9 × 1.6 mm); higher ID = −2.8 A | Better suited for higher-current DC-DC post-regulation where board area permits | Select when >0.5 A load current or lower conduction loss is required; not footprint-compatible |
| AO3401 | RDS(ON) = 85 mΩ @ VGS = −4.5 V; SOT-23; no AEC-Q101 qualification; higher Qg = 2.5 nC | Cost-optimized for consumer portables lacking automotive reliability requirements | Choose for non-automotive designs where gate drive strength exceeds 0.7 nC and qualification is unnecessary |
Compared with DMN2016LFG-7 and AO3401, DMP2900UTQ uniquely balances ultra-small SOT523 footprint, AEC-Q101 compliance, and sub-1 Ω RDS(ON) at 2.5 V logic-making it optimal for space- and reliability-constrained automotive and medical edge nodes.

FAQ
What is the maximum safe operating voltage for DMP2900UTQ in continuous DC applications?
The absolute maximum drain-source voltage (VDSS) is −20 V. Operation above this value risks avalanche breakdown and permanent damage, even with short-duration transients. For 12 V automotive systems, design margin requires limiting VDS to ≤ −16 V under worst-case load-dump conditions per ISO 7637-2.
Can DMP2900UTQ be used with 1.8 V GPIO without external level shifting?
Yes. With VGS(TH) ranging from −0.5 V to −1.0 V and guaranteed turn-on at VGS = −1.8 V (RDS(ON) = 1.3 Ω), the device fully enhances using standard 1.8 V logic outputs. No level shifter is needed, reducing BOM count and layout complexity.
Is the body diode suitable for reverse-current protection in battery backup circuits?
Yes. The integrated body diode has VSD = −0.7 to −1.2 V at −150 mA and is rated for continuous forward current up to −0.39 A. It provides effective reverse-current blocking in dual-battery switchover and UPS hold-up applications without requiring an external Schottky diode.
How does thermal resistance change with PCB copper area for DMP2900UTQ?
RθJA is 496 °C/W with minimum pad layout and 395 °C/W with 1-inch² 2 oz copper. Increasing copper area beyond 1 inch² yields diminishing returns; for automotive applications, use thermal vias under the drain pad and connect to internal ground planes to maintain TJ < 125°C at full ID.
