Product details

Overview

DMP2040UVT-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in TSOT26 package, rated for -20V V_DSS, 38mΩ R_DS(ON) @ V_GS = -4.5V, and -5.5A continuous drain current at T_A = +25°C. It serves as a high-efficiency power switch in low-voltage DC-DC converters and motor control circuits where compact size and low conduction loss are critical.

For engineers reviewing the DMP2040UVT-13 datasheet, DMP2040UVT-13 pinout, DMP2040UVT-13 application, or DMP2040UVT-13 equivalent, key selection criteria include verified R_DS(ON) at -2.5V/-4.5V gate drive, thermal resistance (R_θJA = 80°C/W with enhanced layout), body diode recovery performance (t_RR = 9.8ns), and TSOT26 footprint compatibility with space-constrained PCBs.

Technical Context

This MOSFET employs trench-gate silicon technology optimized for low gate charge (Q_g = 8.6nC @ V_GS = -4.5V) and fast switching (t_F = 14.6ns), enabling high-frequency operation in synchronous buck converters. Its negative threshold voltage (-0.6V to -1.5V) ensures reliable turn-on with standard logic-level gate drivers.

The device integrates an intrinsic body diode with V_SD = -0.7V @ I_S = -2.9A and Q_RR = 2.7nC, supporting efficient freewheeling in half-bridge topologies. Thermal design is enabled by a thermally enhanced TSOT26 package featuring an exposed drain pad with R_θJC = 16°C/W.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-20V - Maximum blocking voltage for 3.3V/5V rail applications
R_DS(ON)	38mΩ @ V_GS = -4.5V - Enables ≤210mW conduction loss at 5.5A
I_D (continuous)	-5.5A @ T_A = +25°C - Supports medium-power load switching without forced cooling
Q_g	8.6nC @ V_GS = -4.5V - Reduces gate driver power and enables >1MHz switching
t_RR	9.8ns - Minimizes reverse recovery loss in hard-switched topologies
R_θJA	80°C/W - Achievable with 2oz copper and thermal pad; enables 1.5W dissipation at ΔT = 120°C
C_iss	834pF - Low input capacitance reduces Miller effect and improves dv/dt immunity

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMG2305UVT-7	R_DS(ON) = 48mΩ @ -4.5V; higher Q_g = 11.5nC; same TSOT26 package	Lower efficiency at high current; less suitable for >500kHz switching	Select when cost sensitivity outweighs 12% higher conduction loss and reduced switching frequency margin
AO3415	R_DS(ON) = 45mΩ @ -4.5V; R_θJA = 120°C/W; no specified t_RR or Q_RR	Higher thermal resistance requires larger copper area; uncharacterized body diode limits hard-switching use	Prefer only in static load switching or low-frequency (<100kHz) applications where thermal headroom exists

Compared with DMG2305UVT-7 and AO3415, DMP2040UVT-13 delivers superior conduction efficiency, lower gate drive demand, and characterized fast-recovery body diode behavior-making it optimal for high-frequency, thermally constrained, and bidirectional current applications.

FAQ

What is the maximum safe operating temperature for DMP2040UVT-13?

The junction temperature must not exceed +150°C under steady-state conditions. With R_θJA = 80°C/W and 1.5W power dissipation, ambient temperature must be held below +30°C unless additional copper area or airflow is applied. Derating curves in Figure 5 confirm usable R_DS(ON) up to +125°C junction.

Can DMP2040UVT-13 be used in a high-side switch configuration with 3.3V logic control?

No-its gate threshold range (-0.6V to -1.5V) requires a negative gate-source voltage for turn-on. A 3.3V logic signal alone cannot achieve sufficient V_GS; a charge pump or level-shifter generating ≥-4.5V relative to source is required for full enhancement-mode operation.

Is the TSOT26 package lead-free and RoHS-compliant?

Yes-DMP2040UVT-13 uses matte tin annealed over copper leadframe and green molding compound, meeting EU RoHS Directive 2011/65/EU and containing <900ppm bromine/chlorine and <1000ppm antimony, as certified in Diodes' official compliance documentation.

Does this MOSFET require external gate resistor for stability?

A gate resistor of 1–10Ω is recommended to dampen ringing caused by L_STRAY × C_iss resonance. The 4.9Ω typical gate resistance (R_G) and 834pF C_iss make it susceptible to oscillation without controlled gate drive impedance, especially in high-dv/dt environments.
