Product details

Overview

DMP22D6UT from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT523 package, rated for -20 V V_DSS, -430 mA continuous drain current at 25°C, and 0.7 Ω R_DS(ON) at V_GS = -4.5 V. It features ESD-protected gate, low gate threshold (-0.5 to -1.0 V), and fast switching speed-used in compact load-switching and battery-protection circuits.

For engineers reviewing the DMP22D6UT datasheet, DMP22D6UT pinout, DMP22D6UT application, or DMP22D6UT equivalent, key selection criteria include its low-voltage gate drive compatibility (V_GS(th) ≤ -1.0 V), ultra-small footprint (SOT523), and guaranteed R_DS(ON) performance down to V_GS = -1.8 V for 150 mA loads in space-constrained portable electronics.

Technical Context

This MOSFET operates as a single P-channel switch with integrated gate protection diode and ESD-hardened structure. Its -20 V V_DSS rating supports operation in 3.3 V and 5 V rail systems, while the -0.5 to -1.0 V V_GS(th) enables direct interface with low-voltage logic outputs without level-shifting.

Thermal resistance of 833 °C/W (R_θJA) reflects its FR-4 PCB mounting condition, and the 150 mW power dissipation limit constrains use to low-duty-cycle or low-current switching applications where junction temperature remains below 150°C under ambient conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-20 V - Maximum blocking voltage across drain-source in off-state; suitable for 3.3 V/5 V system-level load switching.
R_DS(ON) @ V_GS = -4.5 V	0.7 Ω max - Ensures < 200 mW conduction loss at 430 mA, enabling efficient low-power switching.
V_GS(th)	-0.5 to -1.0 V - Guarantees turn-on with standard 1.8 V/3.3 V logic high, eliminating need for gate boosters.
C_iss	175 pF - Low input capacitance reduces gate drive energy and speeds up switching transitions.
P_D	150 mW - Power limit on FR-4 board defines maximum continuous current in ambient air without heatsinking.
ESD Protection	HBM ±2 kV - Integrated gate protection eliminates need for external TVS in most portable designs.

Pinout & Package

Package: SOT523 - ultra-compact surface-mount plastic package (1.60 × 1.60 × 0.75 mm), moisture sensitivity level 1, lead-free and RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
Source (S)	Current return path for P-channel device	Connected to higher potential rail (e.g., battery +); defines reference for gate control.
Gate (G)	Control electrode	Accepts negative V_GS relative to source to enable conduction; ESD-protected per HBM ±2 kV.
Drain (D)	Switched output terminal	Connects to load; polarity reversal required vs. N-channel-drain carries current toward ground when on.

Key Features

Feature	Design Value
Low R_DS(ON) at low V_GS	1.1 Ω max at V_GS = -2.5 V - Enables full on-state operation from 2.5 V logic or partially discharged batteries.
Ultra-small footprint	SOT523 package (1.6 × 1.6 mm) - Saves >50% board area vs. SOT23, critical for wearables and hearing aids.
Low input capacitance	C_iss = 175 pF - Reduces gate charge (Q_g ≈ 1.2 nC estimated) for faster turn-on/turn-off with minimal driver loading.
ESD-hardened gate	HBM ±2 kV rating - Eliminates need for discrete gate protection in handheld and consumer-grade assemblies.

Applications

Battery Protection Circuit

USB Port Power Switch

Use Scenario: Reverse-polarity and over-discharge protection in single-cell Li-ion battery packs.

IC Role / Device Role / Timing Role: P-channel MOSFET used as high-side disconnect switch controlled by protection IC.

Use Value: Low V_GS(th) ensures reliable turn-on even at 2.8 V battery voltage; R_DS(ON) < 1.1 Ω limits voltage drop and heat rise during charging/discharging.

Use Scenario: Hot-swap control of USB 2.0 VBUS power to peripheral devices.

IC Role / Device Role / Timing Role: Load switch isolating downstream circuitry from upstream 5 V supply during insertion/removal.

Use Value: Fast switching (t_on/t_off < 20 ns typical) prevents bus glitches; low leakage (<1 µA IDSS) avoids standby current drain.

Wearable Sensor Power Gate

Low-Voltage Logic-Level Shifter

Use Scenario: Power gating for MEMS accelerometers and optical heart-rate sensors in fitness trackers.

IC Role / Device Role / Timing Role: Controlled power rail switch enabling firmware-triggered sensor sleep/wake cycles.

Use Value: SOT523 size fits tight PCB real estate; 150 mW PD supports 300 mA peak sensor bursts without thermal derating.

Use Scenario: Bidirectional level translation between 1.8 V I²C master and 3.3 V sensor slave.

IC Role / Device Role / Timing Role: Passive level shifter using MOSFET body diode and gate bias configuration.

Use Value: Guaranteed V_GS(th) ≤ -1.0 V allows stable 1.8 V → 3.3 V translation; low C_iss/C_oss preserves signal integrity up to 1 MHz.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2016LFG-7	R_DS(ON) = 0.55 Ω @ -4.5 V; SOT-723 package (smaller than SOT523); higher C_iss (220 pF)	Better conduction loss but tighter layout tolerance; not pin-compatible due to different pad layout	Select when lower R_DS(ON) is critical and board re-layout is feasible.
AO3415	R_DS(ON) = 0.055 Ω @ -4.5 V; SOT-23 package; V_DSS = -20 V; V_GS(th) = -0.5 to -1.3 V	Higher current capability (−4 A), larger footprint, higher gate charge	Choose for higher-current loads (>500 mA) where board space permits SOT-23.

Compared with DMN2016LFG-7 and AO3415, the DMP22D6UT offers optimal balance of ultra-small size, guaranteed low-threshold turn-on, and sufficient R_DS(ON) for sub-500 mA portable applications-making it preferred where SOT523 footprint and 1.8 V logic compatibility are mandatory.

FAQ

Is the DMP22D6UT qualified for automotive applications?

No-the DMP22D6UT is not AEC-Q101 qualified. Diodes offers automotive-grade equivalents with Q-suffix (e.g., DMP22D6UTQ), which undergo additional stress testing, PPAP documentation, and are manufactured in IATF 16949-certified facilities. This part is intended for commercial and industrial use only.

What is the maximum safe operating temperature for continuous use?

The DMP22D6UT has a junction temperature range of -55°C to +150°C. For continuous operation at 430 mA, ambient temperature must remain ≤ 85°C on FR-4 PCB (per R_θJA = 833 °C/W and P_D = 150 mW limit). Derating is required above 25°C ambient to maintain T_J < 150°C.

Can this MOSFET be used in reverse-battery protection circuits?

Yes-its P-channel topology and -20 V V_DSS rating make it suitable for reverse-polarity protection when placed in the high-side position. With V_GS(th) ≤ -1.0 V, it turns on fully at battery voltages ≥ 2.8 V, and its low R_DS(ON) minimizes forward voltage drop and power loss during normal operation.

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

Yes-the SOT523's standardized dimensions, matte tin-plated terminals, and defined solderable finish per MIL-STD-202 meet common AOI system requirements. Its top-view marking (PBA + YM code) and consistent pad layout enable reliable post-reflow verification in high-volume SMT lines.
