Product details
Overview
DMP2900UT-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT523 package, rated for -20V VDSS, 700mΩ RDS(on) at VGS = -4.5V, and -0.5A continuous drain current at +25°C. It features low gate threshold voltage (-0.5V to -1.0V), ESD-protected gate, and is optimized for compact load-switching in space-constrained power management circuits.
For engineers reviewing the DMP2900UT-7 datasheet, DMP2900UT-7 pinout, DMP2900UT-7 application, or DMP2900UT-7 equivalent, key selection criteria include its low-voltage gate drive compatibility (down to -1.8V), normalized RDS(on) stability over -55°C to +150°C, and fast switching performance with 0.7nC total gate charge.
Technical Context
This MOSFET employs a trench-gate process to achieve low RDS(on) while maintaining tight VGS(th) distribution and low input capacitance (Ciss = 49pF). Its body diode exhibits 10.5ns reverse recovery time and 1.8nC QRR, supporting efficient synchronous rectification in low-duty-cycle DC-DC stages.
The device operates with ±6V gate-source rating and supports pulsed drain currents up to -2.5A (10µs, 1% duty). Thermal resistance is 496°C/W (steady-state, minimal pad) and 395°C/W (with 1-inch² copper), enabling operation up to +150°C junction temperature under controlled PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Maximum blocking voltage before avalanche conduction in load-switch or reverse-polarity protection configurations. |
| RDS(on) | 700mΩ @ VGS = -4.5V - Enables <100mW conduction loss at 0.43A, suitable for battery-powered load control. |
| VGS(th) | -0.5V to -1.0V - Allows reliable turn-on from 1.8V/2.5V logic rails without level-shifting circuitry. |
| Qg | 0.7nC - Low gate charge reduces drive power and enables >1MHz switching in compact DC-DC converters. |
| Ciss | 49pF - Minimizes Miller effect and improves noise immunity in high-frequency switching nodes. |
| tRR | 10.5ns - Supports fast body-diode commutation in buck converter freewheeling paths. |
| PD | 0.25W (min pad) - Limits usable continuous current to ~0.5A unless enhanced thermal layout is applied. |
Pinout & Package
Package: SOT523 - ultra-small surface-mount plastic package (1.60 × 1.60 × 0.75 mm), moisture sensitivity level 1, matte tin–annealed terminals solderable per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G | Gate | Control terminal; accepts negative bias relative to source to enable conduction; ESD-protected structure limits gate oxide stress. |
| S | Source | Reference node for gate drive; connects to higher potential rail in high-side switch configuration; carries full load current. |
| D | Drain | Output terminal; connects to load; withstands -20V reverse voltage when off; hosts integrated body diode anode. |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | VGS(th) down to -0.5V enables direct interface with 1.8V I/O controllers without auxiliary biasing. |
| ESD-protected gate | HBM rating ≥2kV ensures robustness during board assembly and handling without external clamping. |
| Low input capacitance | Ciss = 49pF reduces gate drive energy and minimizes switching node ringing in high-dV/dt environments. |
| Fast switching speed | tF = 89ns and tD(off) = 213ns support efficient operation in 500kHz–1MHz DC-DC topologies. |
| Green compound packaging | Halogen- and antimony-free molding compound (<900ppm Br+Cl, <1000ppm Sb) meets automotive and industrial RoHS compliance requirements. |
Applications
| Battery-Powered Load Switch | USB Port Power Control |
|---|---|
Use Scenario: Enabling/disabling power to peripherals in portable medical devices or wearables using 3.3V or lower system rails. IC Role / Device Role / Timing Role: High-side P-channel switch controlling VBUS delivery; driven directly by microcontroller GPIO. Use Value: 700mΩ RDS(on) limits voltage drop to <215mV at 300mA, preserving battery runtime and meeting USB 2.0 voltage tolerance. |
Use Scenario: Overcurrent-protected VBUS switching in USB Type-A receptacles on embedded host controllers. IC Role / Device Role / Timing Role: Reverse-polarity and short-circuit protected power path switch; integrates body diode for fault-current limiting. Use Value: 10.5ns tRR and 1.8nC QRR minimize energy loss during hot-plug transients and reduce thermal stress during fault events. |
| Low-Voltage DC-DC Converter Sync Rectifier | Industrial Sensor Node Power Gating |
Use Scenario: Secondary-side synchronous rectification in isolated 3.3V-output flyback converters for IoT edge nodes. IC Role / Device Role / Timing Role: Low-side synchronous rectifier replacing Schottky diode; driven by transformer-coupled gate signal. Use Value: 0.7nC Qg allows clean turn-on/turn-off timing with minimal gate driver overhead, improving efficiency by >2% at light loads. |
Use Scenario: Periodic wake-up and shutdown of environmental sensors in battery-operated wireless transmitters. IC Role / Device Role / Timing Role: Ultra-low-leakage power gate (IDSS ≤ -100nA) isolating sensor supply during sleep mode. Use Value: Sub-100nA off-state leakage extends 10-year battery life in LPWAN applications where quiescent current dominates energy budget. |
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 |
|---|---|---|---|
| DMG1012T-7 | RDS(on) = 500mΩ @ VGS = -4.5V; SOT-723 package (smaller footprint but same pinout); higher Ciss (65pF). | Better conduction loss but increased gate drive demand; requires tighter layout due to smaller pad area. | Preferred when board space is critical and gate drive capability supports higher Ciss. |
| AO3401 | RDS(on) = 85mΩ @ VGS = -4.5V; SOT-23 package; higher PD (1.4W); no specified ESD rating. | Lower on-resistance enables higher current loads but demands larger thermal pad and lacks factory ESD hardening. | Chosen for higher-power (>1A) applications where SOT-23 mounting and thermal margin outweigh ESD robustness needs. |
Compared with DMG1012T-7 and AO3401, DMP2900UT-7 offers balanced trade-offs: moderate RDS(on) with guaranteed ESD protection and industry-standard SOT523 manufacturability-ideal for cost-sensitive, space-constrained, and reliability-driven designs.

FAQ
Is DMP2900UT-7 suitable for automotive applications?
No-DMP2900UT-7 is not AEC-Q101 qualified. While it shares construction features with automotive-grade variants (e.g., green compound, lead-free finish), Diodes explicitly states that only parts designated as PPAP-capable and manufactured in IATF 16949-certified facilities meet automotive requirements. This part is intended for commercial and industrial use.
What is the maximum safe operating junction temperature?
The absolute maximum junction temperature is +150°C, as specified in the Absolute Maximum Ratings table. Operation at this limit requires strict thermal management: derating to 0.25W power dissipation at ambient +25°C with minimal PCB copper, or up to 0.32W with 1-inch² copper pour per the datasheet's thermal test conditions.
Can DMP2900UT-7 be used in linear regulation mode?
It is not recommended. The device lacks SOA (Safe Operating Area) characterization for linear mode, and its RDS(on) variation with temperature (Figure 6) shows positive feedback above +85°C. The SOA curve (Figure 12) is defined only for single-pulse switching, not DC bias-use only in saturated switching applications.
Does the SOT523 package support reflow soldering per J-STD-020?
Yes-the SOT523 package is rated for Moisture Sensitivity Level 1 (MSL-1), meaning it may be stored indefinitely at ≤30°C/85% RH and is compatible with standard Pb-free reflow profiles (peak 260°C) without baking. Terminal finish is matte tin annealed over Alloy 42, verified solderable per MIL-STD-202, Method 208.
