Product details
Overview
DMP2900UDW-7 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SOT363 package, rated for -20V VDSS, 0.75Ω RDS(ON) @ VGS = -4.5V, and -0.63A continuous drain current at +25°C. It integrates ESD protection and operates across -55°C to +150°C, serving as a compact load switch or relay driver in space-constrained battery-powered systems.
For engineers reviewing the DMP2900UDW-7 datasheet, DMP2900UDW-7 pinout, DMP2900UDW-7 application, or DMP2900UDW-7 equivalent, key selection criteria include low gate threshold (-1.0V max), ultra-small footprint (SOT363), dual-channel complementary operation, and validated performance under pulsed loads up to -2.5A.
Technical Context
This dual P-MOSFET uses planar trench technology to achieve low RDS(ON) while maintaining fast switching (tF = 89ns, tD(OFF) = 213ns) and low input capacitance (Ciss = 49pF). Its gate threshold voltage range (-0.5V to -1.0V) enables reliable turn-on with low-voltage logic controllers.
The device integrates monolithic body diodes with VSD = -0.7V typical at -150mA and supports bidirectional current flow in H-bridge or reverse-polarity protection topologies. Thermal resistance is 272°C/W (with 1-inch² copper pad), enabling stable operation up to 150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Supports rail-to-rail operation in 12V and lower battery systems without breakdown risk. |
| RDS(ON) @ VGS = -4.5V | 0.75Ω max - Limits conduction loss to <0.3W at 0.63A, critical for thermal management in sealed enclosures. |
| VGS(TH) | -0.5 to -1.0V - Ensures full enhancement with 1.8V/2.5V/3.3V GPIOs without level-shifting circuitry. |
| Ciss | 49pF - Reduces gate drive power and enables >1MHz switching in DC-DC converter control paths. |
| tF | 89ns - Minimizes switching transition time, reducing overlap losses in synchronous rectifier applications. |
| TJ Range | -55°C to +150°C - Qualified for extended industrial and automotive cabin environments without derating. |
| Qg | 0.7nC - Enables low-power gate driving with microcontroller outputs or low-current drivers. |
Pinout & Package
Package: SOT363 - ultra-small surface-mount package (2.15mm × 2.10mm × 0.95mm), lead-free, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Q1 Source) | P-Channel MOSFET 1 source terminal | Common source node for first channel; tied to system ground or negative rail in high-side switch configuration. |
| 2 (Q1 Gate) | P-Channel MOSFET 1 gate terminal | Control input for Q1; requires negative voltage relative to source to turn on; compatible with open-drain logic drivers. |
| 3 (Q2 Drain) | P-Channel MOSFET 2 drain terminal | Output node for second channel; used for load connection in dual independent switching or complementary pair operation. |
| 4 (Q2 Source) | P-Channel MOSFET 2 source terminal | Common source node for second channel; may be tied to Q1 source or isolated depending on topology (e.g., dual high-side). |
| 5 (Q2 Gate) | P-Channel MOSFET 2 gate terminal | Independent control input for Q2; enables asynchronous or synchronized dual-channel operation without shared gate drive. |
| 6 (Q1 Drain) | P-Channel MOSFET 1 drain terminal | Primary output node for first channel; connects to load anode or supply rail in reverse-polarity protection circuits. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305UVT-7 | RDS(ON) = 0.52Ω @ -4.5V (lower), but VDSS = -20V same; Ciss = 62pF (higher); SOT-563 package (smaller footprint, no exposed pad) | Better conduction efficiency at high current, but higher gate charge increases drive complexity in low-power systems. | Prefer when minimizing I²R loss dominates over gate drive simplicity and board area is not constrained. |
| SI2301DS-T1-BE3 | RDS(ON) = 0.115Ω @ -4.5V (much lower), VDSS = -20V; SOT-23 package (larger, single-channel only); no integrated ESD diode | Requires two separate devices and external ESD protection; superior thermal dissipation due to larger pad area. | Select when peak current exceeds 0.63A or when board layout allows duplication and thermal relief is prioritized over integration. |
Compared with DMG2305UVT-7 and SI2301DS-T1-BE3, DMP2900UDW-7 offers balanced trade-offs: integrated dual-channel operation in smallest footprint, built-in ESD protection, and gate threshold optimized for 1.8V logic-making it optimal for space- and power-constrained portable designs where component count reduction is critical.

FAQ
What is the maximum continuous drain current for DMP2900UDW-7 at +70°C ambient?
The maximum continuous drain current is -0.5A at TA = +70°C, as specified in the Absolute Maximum Ratings table. This reflects thermal derating due to reduced power dissipation capability (PD = 0.37W at +25°C, decreasing with ambient temperature) and must be verified against actual PCB copper area and airflow conditions.
Does DMP2900UDW-7 require external gate resistors for safe switching?
No external gate resistor is required for basic operation, as its total gate charge is only 0.7nC and input capacitance is 49pF. However, a 10Ω series resistor is recommended in high-noise environments to dampen ringing and limit peak gate current during fast edge transitions, especially when driven directly from MCU GPIOs.
Can DMP2900UDW-7 be used in linear regulation mode?
It is not recommended for sustained linear regulation due to limited power dissipation (0.37W at +25°C) and high RDS(ON) temperature coefficient. The device is optimized for switching operation; use in linear mode risks thermal runaway above 100mW dissipation without aggressive heatsinking.
Is the SOT363 package thermally enhanced with an exposed pad?
No, the SOT363 package used for DMP2900UDW-7 has no exposed thermal pad. Thermal performance relies entirely on soldered leads and PCB copper area; the datasheet specifies RθJA = 340°C/W on standard FR-4 (2oz Cu) and 272°C/W with 1-inch² copper plate-designers must allocate adequate copper pour around pins 1, 4, and 6 for heat spreading.
