Product details

Overview

DMP2004KQ-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -20V V_DSS, 0.9Ω R_DS(ON) at V_GS = -4.5V, and -430mA continuous drain current; it serves as a low-voltage load switch or synchronous rectifier in compact DC-DC converters.

For engineers reviewing the DMP2004KQ-7 datasheet, DMP2004KQ-7 pinout, DMP2004KQ-7 application, or DMP2004KQ-7 equivalent, key selection criteria include gate threshold voltage (V_GS(TH) ≤ -1.0V), low R_DS(ON) at 1.8V drive, AEC-Q101 qualification, and SOT23 thermal resistance (R_θJA = 227°C/W) for automotive power management designs.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low on-resistance while maintaining fast switching (t_D(ON) = 8.5ns, t_F = 19.2ns) and low input capacitance (C_iss = 175pF). Its V_GS(TH) range of -0.5V to -1.0V enables reliable turn-on with 1.8V–2.5V logic-level control signals.

The device integrates ESD protection on the gate terminal and features a body diode with V_SD = -0.5V to -1.2V at I_S = -115mA, supporting bidirectional current handling in buck converter freewheeling paths and reverse-polarity protection circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-20V - maximum blocking voltage for 12V automotive rail and 5V/3.3V system-side isolation
R_DS(ON)	0.9Ω @ V_GS = -4.5V - enables <100mW conduction loss at 330mA, critical for thermally constrained SOT23 layouts
V_GS(TH)	-0.5V to -1.0V - ensures full enhancement with 1.8V GPIO or low-voltage microcontroller outputs
I_D (cont)	-430mA @ T_A = +25°C - defines usable current limit in ambient-limited PCB-mounted applications
C_iss	175pF - reduces gate drive power and improves efficiency in high-frequency (>1MHz) PWM switching
P_D	550mW - sets absolute thermal ceiling under FR-4 board conditions without heatsinking
R_θJA	227°C/W - quantifies junction-to-ambient thermal path for derating calculations in automotive cabin environments

Pinout & Package

SOT23-3 package: surface-mount, 3-terminal plastic case with standard leadframe geometry (dimensions per Diodes Inc. outline SOT23); terminals are matte tin annealed over copper, solderable per MIL-STD-202 Method 208.

2 (Gate)	Control electrode for channel formation	ESD-protected input requiring <1µA leakage; driven low to turn device ON
3 (Drain)	Current output node during conduction	Connected to load or switched rail; hosts body diode cathode for reverse-current blocking

Key Features

Feature	Design Value

Automotive-grade reliability	AEC-Q101 qualified for under-hood operation across -40°C to +125°C ambient temperature range
Low dynamic losses	t_F = 19.2ns and C_oss = 30pF minimize switching energy in 500kHz–2MHz DC-DC topologies
Green packaging	Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets automotive environmental mandates

Applications

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) = 0.5Ω @ V_GS = -4.5V; V_GS(TH) = -0.7V to -1.3V; same SOT23 package	Lower R_DS(ON) supports higher current (650mA), but tighter V_GS(TH) tolerance requires stronger gate drive	Select when lower conduction loss is prioritized over gate drive margin
AO3401	R_DS(ON) = 0.085Ω @ V_GS = -4.5V; V_GS(TH) = -0.7V to -1.3V; SOT23-3, non-AEC-Q101	Higher current rating (4A pulsed) and lower R_DS(ON), but lacks automotive qualification and has higher C_iss (640pF)	Select for cost-sensitive industrial applications where AEC-Q101 is not required

Compared with DMG2305U-7 and AO3401, DMP2004KQ-7 trades slightly higher R_DS(ON) for guaranteed AEC-Q101 compliance, tighter thermal resistance control (227°C/W), and lower C_iss, making it optimal for space-constrained, safety-aware automotive and portable medical systems.

FAQ

What is the maximum continuous drain current for DMP2004KQ-7 at 85°C ambient?

At T_A = +85°C, the continuous drain current is derated to approximately -260mA based on its 550mW power dissipation limit and 227°C/W thermal resistance. This value assumes mounting on a standard FR-4 PCB with no additional copper pour or airflow, and accounts for junction temperature rise to 150°C.

Does DMP2004KQ-7 support 1.8V logic-level gate drive?

Yes - its V_GS(TH) range of -0.5V to -1.0V ensures full enhancement with 1.8V logic outputs. At V_GS = -1.8V, R_DS(ON) is specified at 2.0Ω with I_D = -150mA, confirming functional operation in ultra-low-voltage control scenarios.

How does the ESD protection on the gate terminal affect layout practices?

The integrated ESD protection diode (±1.0µA IGSS max at ±4.5V) allows standard PCB routing without external gate resistors or TVS diodes. However, layout must still minimize parasitic inductance in gate traces to prevent ringing during fast switching, especially in high-frequency DC-DC applications.

Is DMP2004KQ-7 suitable for reverse-battery protection circuits?

Yes - its -20V V_DSS rating and body diode forward voltage of -0.5V to -1.2V make it effective for reverse-polarity protection in 12V automotive systems. When placed in series with the positive rail, it blocks reverse current while adding minimal forward drop during normal operation.
