Product details

Overview

DMP2900UW-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT323 package, rated for -20V V_DSS, 750mΩ R_DS(ON) at V_GS = -4.5V, and -0.6A continuous drain current at +25°C. It serves as a low-voltage load switch or synchronous rectifier in compact DC-DC converters.

For engineers reviewing the DMP2900UW-13 datasheet, DMP2900UW-13 pinout, DMP2900UW-13 application, or DMP2900UW-13 equivalent, key selection criteria include gate threshold voltage (-0.5 to -1.0V), low input capacitance (49pF C_iss), fast switching (16ns t_D(ON)), thermal resistance (272°C/W under enhanced layout), and RoHS-compliant green packaging.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) while maintaining controlled gate charge (0.7nC Q_g) and fast turn-off delay (213ns t_D(OFF)). Its -1.0V typical V_GS(TH) enables direct interface with 1.8V/2.5V logic without level shifting.

The device integrates ESD protection on gate terminals and exhibits low reverse recovery charge (1.8nC Q_RR) and time (10.5ns t_RR), supporting efficient body-diode conduction in buck converter freewheeling paths.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-20V - maximum blocking voltage before avalanche breakdown in load-switch or high-side configuration
R_DS(ON) @ V_GS = -4.5V	750mΩ - enables ≤430mA continuous current with <150mW conduction loss at ambient temperature
V_GS(TH)	-0.5 to -1.0V - ensures reliable turn-on with standard 1.8V I/O or battery-backed control signals
C_iss	49pF - reduces gate drive power and improves switching efficiency in 1–3MHz DC-DC topologies
t_D(ON)/t_F	16ns / 89ns - supports fast transient response and minimizes overlap loss in synchronous rectification
P_D (enhanced layout)	0.5W - achievable with 1-inch² copper pour, enabling 0.6A operation up to +70°C ambient
Q_RR	1.8nC - limits energy dissipation during body-diode commutation in buck converters

Pinout & Package

Package: SOT323 - surface-mount plastic package with 3 terminals, 0.006g mass, UL 94V-0 rating, and moisture sensitivity level 1.

Key Features

Feature	Design Value

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
DMN2011UW-7	R_DS(ON) = 500mΩ @ -4.5V; higher ID rating (-1.0A); same SOT323 package	Better suited for 1A loads but requires tighter gate drive margin due to higher Q_g (1.1nC)	Select when higher current headroom and lower conduction loss are prioritized over minimal gate drive strength
AO3401	R_DS(ON) = 85mΩ @ -4.5V; TO-236AB (SOT23) package; higher thermal resistance (320°C/W)	Lower R_DS(ON) enables higher current, but larger package and inferior thermal performance limit use in ultra-thin designs	Choose only if board area permits SOT23 and thermal derating to 0.4A at +70°C is acceptable

Compared with DMN2011UW-7 and AO3401, DMP2900UW-13 offers optimal balance of ultra-compact SOT323 footprint, verified 1.8V-compatible gate threshold, and sufficient R_DS(ON) for sub-0.6A portable power rails-making it ideal for space- and voltage-constrained load switching where thermal budget is managed via PCB copper area.

FAQ

What is the maximum safe operating junction temperature for DMP2900UW-13?

The absolute maximum junction temperature is +150°C per the datasheet. Continuous operation above +125°C requires derating based on Figure 5 and Figure 6, where R_DS(ON) increases ~1.5× from 25°C to 125°C. Thermal design must ensure T_J stays within this limit using the specified 1-inch² copper pad for 0.5W dissipation.

Can DMP2900UW-13 be used with 1.8V GPIO without a level shifter?

Yes. With a gate threshold voltage range of -0.5V to -1.0V and guaranteed turn-on at V_GS = -1.8V, the device fully enhances using standard 1.8V logic outputs referenced to source. R_DS(ON) = 1500mΩ at -1.8V supports up to 450mA with acceptable loss in low-duty-cycle applications.

Does DMP2900UW-13 have integrated ESD protection on the gate terminal?

Yes. The datasheet explicitly states "ESD Protected Gate" in the Features section and specifies HBM ESD rating ≥2kV per JEDEC JS-001. No external gate Zener or RC snubber is required for typical handling and PCB-level ESD environments.

What is the recommended PCB pad layout for thermal performance?

For 0.5W power dissipation, Diodes recommends a 1-inch² copper pour connected to the source pad via multiple thermal vias. The SOT323 outline drawing (page 6) defines exact pad dimensions: 2.15mm × 2.10mm land pattern with 0.65mm pitch. Minimum 2oz copper thickness and solder mask defined pads are required to achieve the 272°C/W R_θJA.
