Product details
Overview
DMP2900UFB-7B from Diodes Incorporated is a P-channel enhancement-mode MOSFET in a 1.0 mm × 0.6 mm X1-DFN1006-3 package, rated for -20 V VDSS, 0.75 Ω RDS(ON) @ VGS = -4.5 V, -0.99 A continuous drain current at +25°C, and optimized for low-footprint load switching in space-constrained portable power rails.
For engineers reviewing the DMP2900UFB-7B datasheet, DMP2900UFB-7B pinout, DMP2900UFB-7B application, or DMP2900UFB-7B equivalent, key selection criteria include gate threshold voltage (-0.5 to -1.0 V), normalized RDS(ON) stability over -55°C to +150°C, ESD-protected gate, and thermal resistance (113°C/W with copper pad).
Technical Context
This MOSFET operates as a high-side load switch with fast turn-on (16 ns delay) and turn-off (213 ns delay) timing, enabled by low total gate charge (0.7 nC) and minimal input capacitance (49 pF). Its low VGS(TH) ensures reliable activation from 2.5 V logic-level controllers.
The device integrates an intrinsic body diode (VSD = -0.7 to -1.2 V @ IS = -150 mA) and is characterized for stable RDS(ON) across temperature - varying only 1.6× from -55°C to +150°C at VGS = -4.5 V - supporting robust operation in battery-powered industrial and consumer systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20 V - Maximum blocking voltage for 3.3 V/5 V rail protection without avalanche stress |
| RDS(ON) | 0.75 Ω @ VGS = -4.5 V - Enables <100 mW conduction loss at 430 mA load current |
| ID (continuous) | -0.99 A @ TA = +25°C - Sustains typical USB peripheral or sensor rail loads on minimal PCB area |
| VGS(TH) | -0.5 to -1.0 V - Ensures full enhancement with 1.8 V–3.3 V GPIO control without level shifting |
| Qg | 0.7 nC - Reduces gate drive power and enables >1 MHz PWM switching in power sequencing |
| RθJA | 113 °C/W - Achievable with 25 mm² copper pour; supports 550 mW dissipation at +70°C ambient |
| Ciss | 49 pF - Limits capacitive loading on driving MCU pins and improves EMI margin |

| 2 (Drain) | Drain terminal (D) | Switched output node; connects to load; exposed pad (pin 3) thermally anchors to PCB copper |
| 3 (Gate) | Gate terminal (G) | Logic-controlled input; ESD-protected; requires <1.0 V overdrive for full enhancement due to low VGS(TH) |
Key Features
| Feature | Design Value |
|---|---|
| 0.6 mm² footprint | 13× smaller than SOT-23 - saves critical area in wearables, TWS earbuds, and compact IoT sensors |
| Low VGS(TH) | -0.5 to -1.0 V range - eliminates need for gate driver or charge pump in 1.8 V/2.5 V microcontroller interfaces |
| ESD-protected gate | HBM ±2 kV rating - withstands handling and board assembly without external clamping diodes |
| Thermal performance | RθJA = 113 °C/W with 25 mm² copper - enables 550 mW operation without derating in sealed enclosures |

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 |
|---|---|---|---|
| DMN2011UFD-7 | RDS(ON) = 0.85 Ω @ -4.5 V; larger X1-DFN1212-3 (1.2 mm × 1.2 mm) package | Higher thermal mass but lower current density; better suited for 1.2 A continuous loads | Select when >1 A DC capability is required and board space permits 2.2× larger footprint |
| AO3415 | RDS(ON) = 0.055 Ω @ -4.5 V; SOT-23 package; VDSS = -20 V; no ESD protection | Lower conduction loss but requires external ESD diodes and occupies 3.5× more PCB area | Choose only if ultra-low RDS(ON) dominates design priority and layout allows SOT-23 placement |
Compared with DMN2011UFD-7 and AO3415, DMP2900UFB-7B uniquely balances sub-1 mm² size, integrated ESD protection, and verified -55°C to +150°C RDS(ON) stability - making it optimal for miniaturized, unbuffered, wide-temperature embedded power switches.

FAQ
What is the maximum safe operating junction temperature for DMP2900UFB-7B?
The absolute maximum junction temperature is +150°C, and the device is characterized for RDS(ON) stability up to this limit. With RθJA = 113°C/W on a 25 mm² copper pad, sustained 550 mW dissipation is achievable at +70°C ambient - well within thermal safety margins for most portable and industrial applications.
Does DMP2900UFB-7B require external gate resistors for ESD or switching control?
No external gate resistor is required for ESD protection - the device integrates on-chip ESD structures rated to ±2 kV HBM. A small series resistor (≤10 Ω) may be added to damp ringing in high-speed switching, but it is not needed for basic load-switch operation driven by standard GPIO.
Can DMP2900UFB-7B be used in automotive applications?
DMP2900UFB-7B is not AEC-Q101 qualified. While its -55°C to +150°C operating range and green compliance meet baseline environmental requirements, Diodes specifies that automotive-grade versions require explicit qualification, PPAP documentation, and IATF 16949 manufacturing - contact Diodes directly for such variants.
How does the body diode forward voltage affect reverse-current blocking performance?
The body diode has VSD = -0.7 to -1.2 V at -150 mA, enabling effective reverse-current blocking when the MOSFET is off. In high-side configuration, this prevents backfeed from downstream loads - critical in battery-backed systems where leakage must remain below 100 nA, as confirmed by IDSS ≤ -100 nA at -20 V.
