Product details

Overview

DMP2065U-13 from Diodes Incorporated is a 20V P-channel enhancement-mode MOSFET in SOT-23 package, rated for -4.0A continuous drain current at 25°C, with R_DS(on) = 60 mΩ @ V_GS = -4.5V and gate threshold voltage of -0.5 to -0.9V. It serves as a low-side load switch or reverse-polarity protection device in compact DC/DC converters and battery-powered systems.

For engineers reviewing the DMP2065U-13 datasheet, DMP2065U-13 pinout, DMP2065U-13 application, or DMP2065U-13 equivalent, key selection criteria include verified R_DS(on) at low gate drive (-2.5V), thermal resistance (R_θJA = 138 °C/W on FR-4), fast switching (t_D(off) = 79.3 ns), and RoHS-compliant green packaging.

Technical Context

This P-channel MOSFET operates with negative gate-source control logic, enabling simple high-side or low-side switching without level-shifting circuitry. Its low V_GS(th) ensures reliable turn-on from 3.3V or 5V microcontroller GPIOs, while low C_iss (808 pF) and Q_g (10.2 nC) support efficient PWM operation up to several hundred kHz.

The device integrates an intrinsic body diode with V_SD = -0.7 to -1.1V at -1A, supporting synchronous rectification or flyback recovery. Thermal design is constrained by its 0.9W steady-state power dissipation on standard FR-4 PCB, requiring careful layout per Diodes' recommended pad dimensions (X=0.8 mm, Y=0.9 mm).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-20 V - Maximum blocking voltage before avalanche conduction; defines safe operating range in 12V automotive or 15V industrial rails.
R_DS(on)	60 mΩ @ V_GS = -4.5V - Confirmed on-resistance at standard logic-level drive; enables ≤240 mW conduction loss at 2A load.
I_D	-4.0 A @ T_A = +25°C - Continuous DC current rating under defined PCB thermal conditions; derates to -3.0 A at 70°C ambient.
Q_g	10.2 nC - Total gate charge required for full turn-on; determines driver strength requirement and switching energy loss.
C_iss	808 pF - Input capacitance at V_DS = -15V; impacts gate drive loop stability and rise/fall time in high-frequency switching.
V_GS(th)	-0.5 to -0.9 V - Gate threshold voltage range; ensures guaranteed turn-on with 3.3V I/O and supports low-voltage battery cutoff circuits.
t_D(off)	79.3 ns - Turn-off delay time under defined test conditions (V_GS = -4.5V, R_G = 6Ω); critical for dead-time management in half-bridge topologies.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMG2305U-7	R_DS(on) = 48 mΩ @ -4.5V (lower), but ID = -4.2A; slightly higher C_iss (850 pF)	Same SOT-23 footprint; better conduction efficiency at same drive, marginally slower switching	Preferred where lower conduction loss dominates over switching loss, e.g., always-on battery backup paths.
SI2301DDS-T1-GE3	R_DS(on) = 115 mΩ @ -4.5V (higher); V_GS(th) = -0.4 to -1.0V; Q_g = 5.5 nC (lower)	Compatible SOT-23; faster turn-on due to lower Q_g, but higher resistive loss at >1A loads	Preferred for ultra-low-power wake-up circuits where gate drive energy matters more than steady-state loss.

Compared with DMG2305U-7 and SI2301DDS-T1-GE3, DMP2065U-13 offers balanced trade-offs: mid-range R_DS(on) and Q_g, verified -2.5V drive capability, and industry-standard thermal performance on FR-4-making it optimal for cost-sensitive, thermally constrained 3.3V/5V control applications.

FAQ

What is the maximum continuous drain current for DMP2065U-13 at 70°C ambient?

The DMP2065U-13 is rated for -3.0 A continuous drain current at T_A = +70°C under specified FR-4 PCB mounting conditions (minimum pad layout). This derating reflects thermal limits imposed by R_θJA = 138 °C/W and 0.9W power dissipation ceiling. At higher ambient temperatures, further linear derating applies down to zero current at 150°C junction temperature.

Does DMP2065U-13 support gate drive from a 3.3V microcontroller GPIO?

Yes. With a gate threshold voltage range of -0.5 to -0.9 V and R_DS(on) = 90 mΩ at V_GS = -2.5V, the DMP2065U-13 fully enhances using a 3.3V MCU's GPIO pulled low through a series resistor. Verified operation includes -3.4A current at -2.5V drive, making it suitable for direct interface without level-shifting circuitry.

Is the body diode in DMP2065U-13 suitable for reverse recovery in synchronous rectification?

No. The intrinsic body diode has no specified reverse recovery time (t_rr) and exhibits soft recovery behavior typical of planar MOSFETs-not optimized for high-frequency freewheeling. Its V_SD = -0.7 to -1.1V at -1A makes it acceptable for low-frequency catch diode roles, but not for synchronous rectification above ~50 kHz where fast, low-Q_rr diodes are required.

What is the moisture sensitivity level (MSL) and floor life for DMP2065U-13?

The DMP2065U-13 is rated MSL 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and may be subjected to standard reflow profiles without pre-baking. This classification is confirmed by Diodes' packaging documentation and applies to both DMP2065U-7 and DMP2065U-13 tape-and-reel variants.
