Product details
Overview
DMP2305UVT-7 from Diodes Incorporated is a 20V P-channel enhancement-mode MOSFET in TSOT26 package, rated for -4.23A continuous drain current at VGS = -4.5V, with 45mΩ typical RDS(on), low 727pF input capacitance, and AEC-Q101 qualified for automotive-grade reliability - deployed in synchronous buck converter high-side switches and motor driver H-bridge legs.
For engineers reviewing the DMP2305UVT-7 datasheet, DMP2305UVT-7 pinout, DMP2305UVT-7 application, or DMP2305UVT-7 equivalent, key selection criteria include verified -20V VDSS, gate threshold range (-0.5V to -0.9V), thermal resistance (76°C/W on 1-inch2 copper), body diode forward voltage (0.85V @ -1A), and TSOT26 footprint compatibility with space-constrained DC-DC modules.
Technical Context
This P-channel MOSFET operates as a high-side load switch or synchronous rectifier in buck converters, leveraging its negative gate threshold and low RDS(on) to minimize conduction loss at 3.3V–5V logic-level drive. Its 7.6nC total gate charge and 14ns turn-on delay enable efficient switching up to ~1MHz in compact power stages.
The device integrates a robust body diode with -4.23A continuous forward rating and exhibits stable RDS(on) over temperature (1.4× increase from -55°C to 150°C at VGS = -4.5V), supporting operation across automotive under-hood ambient ranges without derating beyond datasheet limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V maximum drain-source blocking voltage - supports 12V automotive rail and 15V industrial bus designs with margin. |
| RDS(on) | 45mΩ typical @ VGS = -4.5V - delivers ≤180mW conduction loss at -2A, critical for thermally constrained PCB layouts. |
| ID (cont) | -4.23A @ TA = 25°C - enables ≥5W power delivery in TSOT26 with standard FR-4 board layout. |
| Ciss | 727pF - determines gate drive strength requirement; compatible with low-current controllers like AP3418 or TPS54332. |
| Qg | 7.6nC - sets switching energy; allows <1μs transition time with 10mA gate driver, minimizing overlap loss. |
| RθJA | 76°C/W (1-inch2 copper) - enables 1.25W dissipation with ≤95°C junction rise above 55°C ambient. |
| VGS(th) | -0.5V to -0.9V - ensures reliable turn-on with 3.3V GPIO or LDO output, eliminating need for level-shifting. |
Pinout & Package
Package: TSOT26 - ultra-thin surface-mount package (1.0mm height), 2.9mm × 2.8mm footprint, 6-pin leadframe with matte tin finish, moisture sensitivity level 1, UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Source terminal (P-channel) | Connected to input rail in high-side switch; carries full load current and serves as reference for gate drive. |
| 2 (Gate) | Control input | Receives negative gate voltage relative to source; 23Ω gate resistance limits ringing during fast switching. |
| 3 (Drain) | Output/switching node | Connects to load or inductor node; must be routed with low-inductance path to minimize voltage overshoot. |
| 4 (Drain) | Parallel drain connection | Internally bonded to Pin 3 to reduce on-resistance and thermal resistance - requires common copper pour. |
| 5 (Source) | Parallel source connection | Internally bonded to Pin 1 to improve current sharing and heat spreading - must tie to same net. |
| 6 (Drain) | Parallel drain connection | Third drain bond wire enhances current capacity and reduces package inductance in high-frequency operation. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at logic-level drive | 45mΩ @ VGS = -4.5V enables direct interface with 3.3V/5V microcontrollers without gate drivers. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules and body electronics requiring extended temperature and reliability compliance. |
| Green packaging | Halogen- and antimony-free molding compound (<900ppm Br+Cl, <1000ppm Sb) meets global environmental regulations. |
| Fast switching performance | 14ns turn-on delay + 13ns rise time supports >500kHz PWM in point-of-load converters with minimal dead-time loss. |
| Optimized body diode | Forward voltage of 0.85V @ -1A and reverse recovery Qrr optimized for synchronous rectification in buck topologies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305U-7 | Same die, identical RDS(on) and Qg, but in SOT-26 (slightly larger footprint, 1.1mm height) | SOT-26 has higher RθJA (100°C/W vs. 76°C/W), limiting power handling in dense layouts | Select when legacy SOT-26 footprint compatibility is required and thermal margin permits. |
| AO3401 | Higher RDS(on) (62mΩ @ -4.5V), higher Ciss (850pF), no AEC-Q101 qualification | Not suitable for automotive; acceptable for consumer DC-DC where cost is prioritized over thermal performance | Choose only for non-automotive, cost-sensitive applications with relaxed efficiency targets. |
Compared with DMG2305U-7 and AO3401, DMP2305UVT-7 delivers superior thermal performance in ultra-thin form factor and certified reliability for safety-critical automotive use - making it the optimal choice when board thickness, power density, and qualification compliance are jointly constrained.

FAQ
What is the maximum safe operating temperature for DMP2305UVT-7 in continuous operation?
The junction temperature must not exceed 150°C. With RθJA = 76°C/W on a 1-inch2 copper pad, the device supports 1.25W continuous power dissipation at 55°C ambient. Derating is required above 55°C ambient per Figure 7; at 105°C ambient, max power drops to ~0.6W.
Can DMP2305UVT-7 be used in a synchronous rectifier configuration?
Yes - its low RDS(on) (45mΩ typ.), fast switching (tD(off) = 53.8ns), and optimized body diode (VSD = 0.85V @ -1A) make it suitable for synchronous rectification in buck converters up to 1MHz. Gate drive must swing below source potential by ≥4.5V for full enhancement.
Does DMP2305UVT-7 require a gate resistor for EMI suppression?
A 10Ω–22Ω series gate resistor is recommended to dampen ringing caused by PCB trace inductance interacting with Ciss (727pF) and internal RG (23Ω). This improves EMI performance without significantly impacting 14ns turn-on delay in typical 3.3V/5V drive configurations.
Is the TSOT26 package of DMP2305UVT-7 compatible with standard SMT reflow profiles?
Yes - the TSOT26 package is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260°C. Its moisture sensitivity level 1 eliminates bake requirements, and the matte tin finish ensures reliable solderability using standard SnAgCu pastes and nitrogen or air reflow atmospheres.
