Product details

Overview

DMP2037U-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -20V V_DSS, 28 mΩ R_DS(ON) @ V_GS = -4.5V, and -6.1A continuous drain current at T_A = +25°C. It serves as a low-side load switch in portable power rails, battery protection circuits, and USB port power control.

For engineers reviewing the DMP2037U-13 datasheet, DMP2037U-13 pinout, DMP2037U-13 application, or DMP2037U-13 equivalent, key selection criteria include guaranteed R_DS(ON) at -2.5V gate drive, ESD-protected gate, low C_iss (803 pF), and thermal resistance of 158 °C/W on FR-4 board - critical for compact DC-DC output stage and always-on rail switching.

Technical Context

This device operates as a single P-channel silicon MOSFET with integrated gate protection diode and ESD-hardened structure. Its threshold voltage range (-0.5 V to -1.2 V) enables reliable turn-on from standard 3.3 V or 5 V logic rails when referenced to source, and its low Q_g (8.4 nC @ V_GS = -4.5 V) supports fast switching in high-frequency load switching applications.

The SOT23 package features a thermally enhanced drain pad connected to the internal die's backside, delivering R_θJC = 14.3 °C/W and enabling 1.6 W power dissipation under optimized PCB layout. Body diode forward voltage is -0.66 V @ I_S = -1 A, supporting reverse-current blocking in bidirectional power paths.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-20 V - Maximum drain-source blocking voltage for 3.3 V/5 V system rails with margin
R_DS(ON)	28 mΩ @ V_GS = -4.5 V - Enables <170 mW conduction loss at 6.1 A, suitable for low-voltage load switching
I_D (continuous)	-6.1 A @ T_A = +25°C - Supports USB-C PD sink-side power path and battery disconnect up to 6 A
C_iss	803 pF - Low input capacitance reduces gate drive power and speeds up turn-on in logic-level switching
Q_g	8.4 nC @ V_GS = -4.5 V - Allows clean 10–20 ns switching edges with 1 Ω gate resistor
V_GS(TH)	-0.5 to -1.2 V - Ensures full enhancement with 3.3 V GPIO, eliminating need for level shifters
T_J Range	-55 to +150 °C - Qualified for industrial and extended-temperature embedded systems

Applications

USB Power Delivery Switching

Battery Protection Circuit

Use Scenario: Selectively enable/disable 5 V/3 A power delivery to downstream USB peripherals while maintaining bus enumeration integrity.

IC Role / Device Role: Low-side load switch controlling VBUS path; gate driven directly by microcontroller GPIO.

Use Value: 28 mΩ R_DS(ON) limits voltage drop to <170 mV at 6 A, preserving USB 2.0 signaling margins and reducing thermal footprint.

Use Scenario: Isolate Li-ion battery cell from system during over-discharge or short-circuit fault conditions.

IC Role / Device Role: Reverse-polarity and overcurrent protection switch placed between battery anode and system ground.

Use Value: -20 V rating accommodates 4S battery packs (≤16.8 V); body diode blocks reverse current during hot-swap events.

Always-On Rail Management

IoT Sensor Node Power Gating

Use Scenario: Maintain uninterrupted power to RTC, PMIC, or wake-up controller while main SoC enters deep sleep.

IC Role / Device Role: High-efficiency P-channel switch isolating backup rail from main supply during standby.

Use Value: 1 µA I_DSS leakage ensures <1 µA total quiescent current draw, extending coin-cell life beyond 5 years.

Use Scenario: Power-gate discrete sensors (e.g., temperature, motion) in battery-powered edge nodes to minimize idle consumption.

IC Role / Device Role: Logic-controlled power switch placed between LDO output and sensor VDD pins.

Use Value: Fast 6 ns rise time enables sub-10 µs power-up sequencing; low Q_g minimizes MCU GPIO loading during frequent on/off cycles.

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
DMG2305U-7	R_DS(ON) = 45 mΩ @ -2.5 V; higher C_iss (1050 pF); same SOT23 package	Higher gate charge increases drive requirement; less suitable for 2.5 V logic interfaces	Select when cost sensitivity outweighs 2.5 V drive capability and lower R_DS(ON) is acceptable
AO3401	R_DS(ON) = 50 mΩ @ -2.5 V; no integrated gate ESD diode; RoHS-compliant but not halogen-free	Lacks built-in ESD protection - requires external TVS or RC snubber in noisy environments	Prefer where legacy qualification or second-source availability is prioritized over green compliance and robustness

Compared with DMG2305U-7 and AO3401, DMP2037U-13 delivers superior 2.5 V drive capability, lower switching losses, and integrated ESD hardening - making it optimal for space-constrained, battery-sensitive IoT and portable designs requiring long-term reliability without external protection.

FAQ

What is the maximum safe operating junction temperature for DMP2037U-13?

The absolute maximum junction temperature is +150 °C per the datasheet. Derating begins at +25 °C ambient, with R_θJA = 158 °C/W on standard FR-4. At 6.1 A continuous current and 28 mΩ R_DS(ON), junction temperature rises ~270 °C above ambient - confirming that practical operation requires thermal relief (e.g., copper pour, 2 oz layers) to stay within safe limits.

Can DMP2037U-13 be used in high-side switching configurations?

Yes, but gate drive must be referenced to the source node. Since it is a P-channel device, high-side use requires a gate voltage ≤ source voltage by at least |V_GS(TH)|. For 5 V rail switching, a dedicated high-side driver or charge pump is needed to pull gate below source - unlike N-channel alternatives that simplify high-side control with bootstrap circuits.

Does DMP2037U-13 have avalanche rating or UIS capability?

No. The datasheet does not specify Unclamped Inductive Switching (UIS) or single-pulse avalanche energy (E_AS) ratings. It is intended for resistive or capacitive loads only. For inductive switching (e.g., solenoids, relays), external clamping diodes or snubbers are mandatory to prevent drain voltage overshoot beyond -20 V.

Is the SOT23 package of DMP2037U-13 lead-free and RoHS 3 compliant?

Yes. DMP2037U-13 is fully RoHS 3 compliant (2015/863/EU), with no intentionally added lead, and classified as "Green" - containing <900 ppm bromine, <900 ppm chlorine, and <1000 ppm antimony compounds. Terminal finish is matte tin annealed over copper leadframe, solderable per MIL-STD-202, Method 208.
