Product details

Overview

DMP21D1UTQ-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT523 package, rated for -20V V_DSS, 710mΩ R_DS(ON) at V_GS = -4.5V, and -0.63A continuous drain current at T_A = +25°C. It serves as a low-voltage load switch or power-management device in space-constrained automotive and portable electronics.

For engineers reviewing the DMP21D1UTQ-13 datasheet, DMP21D1UTQ-13 pinout, DMP21D1UTQ-13 application, or DMP21D1UTQ-13 equivalent, key selection criteria include gate threshold voltage (-0.5 to -1.0V), low input capacitance (33pF C_iss), AEC-Q101 qualification, and thermal resistance (480°C/W R_θJA on minimal pad layout).

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) at low gate drive voltages, enabling operation with 2.5V–4.5V logic-level control. Its ESD-protected gate and low leakage (<±10μA I_GSS) support robustness in unbuffered digital interface environments.

The device exhibits fast switching performance (t_D(ON) = 4.6ns, t_F = 7.9ns) and stable on-resistance over temperature (±15% variation from -55°C to +150°C at fixed V_GS). Its body diode has V_SD = -0.8 to -1.2V at I_S = -300mA, supporting synchronous rectification or reverse-polarity protection roles.

Key Specifications

Q_g	1.4nC - Total gate charge affecting driver sizing and switching loss

Pinout & Package

Package: SOT523 - ultra-small surface-mount plastic package (1.60 × 1.60 × 0.55 mm), rated for moisture sensitivity level 1 (MSL-1), with matte tin annealed terminals solderable per MIL-STD-202.

Pin/Terminal	Circuit Role	Design Meaning

Source (S)	Reference node for gate drive and current return path	Connected to higher potential rail in high-side switch configuration; defines V_GS reference
Drain (D)	Power output terminal	Carries load current when channel is enhanced; connected to load or ground depending on circuit topology

Key Features

Feature	Design Value

ESD-protected gate	HBM rating ≥2kV ensures robustness against handling and board-level ESD events
AEC-Q101 qualified	Validated for automotive applications including engine control modules and body electronics
Green, halogen-free construction	Meets RoHS 3 and JEDEC J-STD-020 MSL-1 requirements for lead-free assembly and environmental compliance
Low input/output leakage	I_GSS ≤ ±10μA and I_DSS ≤ -1μA minimize standby power loss in battery-powered systems

Applications

Automotive Body Control Module

IC Role / Device Role / Timing Role: High-side load switch managing power delivery with reverse-polarity protection via integrated body diode.

Use Value: Low R_DS(ON) minimizes voltage drop and heat generation during sustained 500mA operation; AEC-Q101 qualification ensures reliability across -40°C to +125°C ambient.

Use Scenario: Enabling/disabling V_BUS paths in USB-C receptacles where space limits larger packages.

IC Role / Device Role / Timing Role: Bidirectional power-path switch with fast turn-off (t_F = 7.9ns) to meet USB PD fault response timing.

Use Value: SOT523 footprint saves >60% PCB area vs. SOT23; low C_iss reduces gate drive burden from Type-C controller GPIOs.

Portable Medical Sensor Node

Industrial IoT Edge Controller

Use Scenario: Isolating sensor supply rails in battery-operated wearable monitors to extend runtime.

IC Role / Device Role / Timing Role: Low-quiescent-load power gate controlled by MCU GPIO to sequence sensor activation.

Use Value: Sub-1μA I_DSS prevents measurable battery drain during sleep; -0.63A rating supports peak current of optical pulse oximetry LEDs.

Use Value: Stable R_DS(ON) over temperature ensures predictable voltage drop across full industrial operating range; PPAP-capable sourcing supports long-lifecycle production.

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
DMN2011UFD-7	Higher R_DS(ON) (1.2Ω @ -4.5V), larger TSOP-6 package, 2.5A rating	Designed for higher-current DC-DC sync rectification, not space-constrained load switching	Select only if >1A current capability and board area allow TSOP-6 footprint
AO3401	Lower V_DSS (-30V), higher R_DS(ON) (85mΩ @ -10V but 1.4Ω @ -2.5V), SOT23 package	Lacks AEC-Q101 qualification; gate threshold less suitable for 1.8V logic	Acceptable for non-automotive consumer designs where cost outweighs qualification and low-V_GS performance

Compared with DMN2011UFD-7 and AO3401, DMP21D1UTQ-13 uniquely balances ultra-small SOT523 size, AEC-Q101 compliance, and sub-1V gate threshold-making it optimal for automotive and portable systems where board space, qualification, and low-voltage drive are jointly critical.

FAQ

What is the maximum continuous drain current at 75°C ambient?

The DMP21D1UTQ-13 supports -0.51A continuous drain current at T_A = +75°C, derated from -0.63A at +25°C due to thermal limitations of the SOT523 package on standard FR-4 board. This value assumes no forced airflow and minimum recommended copper pad layout.

Is this MOSFET suitable for reverse-polarity protection?

Yes-the integrated body diode provides inherent reverse-polarity protection when used in high-side configuration. With V_SD = -0.8 to -1.2V at -300mA and low R_DS(ON), it delivers efficient forward conduction while blocking reverse current up to -20V, meeting typical automotive load-dump and battery-reversal requirements.

Does the SOT523 package support automated optical inspection (AOI)?

Yes-the SOT523's standardized top-view marking (e3, BR3, YM date code) and defined pad layout per Diodes' package outline drawings enable reliable AOI detection. Its 0.5mm pitch and visible G-S-D terminals allow standard vision systems to verify placement and solder joint integrity post-reflow.

How does the gate charge affect driving from a 3.3V microcontroller?

With Q_g = 1.4nC and V_GS(TH) as low as -0.5V, the DMP21D1UTQ-13 turns fully on using a 3.3V GPIO pulled low (i.e., 0V source, -3.3V gate). Rise/fall times remain sub-10ns with 6Ω series gate resistance, enabling PWM switching up to ~5MHz without excessive driver heating or shoot-through risk.
