Product details

Overview

DMP3160LQ-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -30V V_DSS, 122mΩ R_DS(ON) @ V_GS = -10V, and -2.7A continuous drain current at T_A = +25°C. It serves as a low-side load switch or synchronous rectifier in compact DC-DC converters requiring high efficiency and fast switching.

For engineers reviewing the DMP3160LQ-7 datasheet, DMP3160LQ-7 pinout, DMP3160LQ-7 application, or DMP3160LQ-7 equivalent, key selection criteria include gate threshold voltage (-1.3 to -2.1V), normalized R_DS(ON) stability over -55°C to +150°C, and low 384.4pF C_iss for optimized gate drive loss in high-frequency power stages.

Technical Context

This MOSFET uses planar trench technology to achieve low on-resistance while maintaining tight V_GS(TH) distribution and low input capacitance. Its -1.8V typical gate threshold enables direct interface with 3.3V logic-level controllers without level shifting.

The device features integrated body diode with -1.26V forward voltage at -2.7A, supporting bidirectional current flow in buck converter freewheeling paths. Thermal resistance of 115°C/W (Junction-to-Ambient, FR-4 PCB) defines its power handling under natural convection conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-30V - Maximum blocking voltage in off-state; supports 24V rail systems with margin.
R_DS(ON)	122mΩ @ V_GS = -10V - Conduction loss of 840mW at -2.7A; enables >92% efficiency in 5V→3.3V buck stage.
I_D (continuous)	-2.7A @ T_A = +25°C - Rated current for PCB-mounted operation without heatsink.
V_GS(TH)	-1.3 to -2.1V - Ensures reliable turn-on with standard 3.3V GPIO or PWM controllers.
C_iss	384.4pF - Low input capacitance reduces gate drive power and speeds up switching transitions.
t_F	13.4ns - Fast fall time minimizes overlap loss during hard-switched transitions.
P_D	1.08W - Power dissipation limit at T_A = +25°C; derates linearly above 25°C ambient.

Pinout & Package

Package: SOT23 - Surface-mount plastic package (2.9mm × 1.3mm × 1.0mm), moisture sensitivity level 1, matte tin–annealed copper leadframe, RoHS-compliant and halogen-free.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Source terminal	Common return path for load current; tied to system ground in low-side switch configuration.
2 (Gate)	Control input	Receives negative gate drive relative to source; requires <2.1V magnitude to fully enhance.
3 (Drain)	Power output	Connects to load or inductor node; handles full switched current and blocking voltage.

Key Features

Feature	Design Value
Low R_DS(ON)	122mΩ @ -10V enables <0.9W conduction loss at 2.7A, reducing thermal stress in space-constrained layouts.
Low V_GS(TH)	-1.8V typical threshold allows direct drive from 3.3V microcontrollers without external level shifters.
Fast switching	4.8ns t_D(ON) and 13.4ns t_F minimize dead-time losses in synchronous rectification.
Low leakage	<800nA I_DSS at -30V ensures minimal standby power draw in battery-powered systems.
Green packaging	Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets IPC-1752A Class 3 requirements.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMG3415L-7	R_DS(ON) = 42mΩ @ -4.5V (lower), but V_DSS = -20V (reduced voltage margin)	Better suited for 5V/3.3V logic rails only; unsuitable for 24V systems due to lower breakdown rating	Select when V_IN ≤ 12V and lowest possible R_DS(ON) is critical
AO3401	R_DS(ON) = 115mΩ @ -4.5V (slightly lower), C_iss = 420pF (higher), no AEC-Q200 qualification	Higher gate charge increases driver loss; lacks automotive-grade traceability and PPAP support	Select for cost-sensitive consumer designs where automotive compliance is not required

Compared with DMG3415L-7 and AO3401, DMP3160LQ-7 offers optimal balance of -30V robustness, 122mΩ R_DS(ON) at logic-compatible -4.5V, and full RoHS/halogen-free compliance-making it preferred for industrial power management where voltage margin and regulatory alignment are non-negotiable.

FAQ

What is the maximum continuous drain current for DMP3160LQ-7 at 70°C ambient?

The maximum continuous drain current is -2.0A at T_A = +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the SOT23 package on standard FR-4 PCB with no forced airflow or heatsinking.

Does DMP3160LQ-7 have an integrated ESD protection diode?

No, DMP3160LQ-7 does not include integrated ESD protection diodes. The device meets HBM ESD rating of ±2kV per JEDEC JS-001, but external TVS or RC filtering is recommended for gate protection in noisy environments.

Can DMP3160LQ-7 be used in automotive applications?

DMP3160LQ-7 is not AEC-Q101 qualified. While it operates from -55°C to +150°C, Diodes specifies that automotive-grade versions require explicit AEC-Q101 qualification, PPAP documentation, and IATF 16949 manufacturing-none of which apply to this part number.

What is the gate charge required to fully switch DMP3160LQ-7 at -4.5V?

The total gate charge Q_g is 4.0nC when driven from 0V to -4.5V, as measured at V_DS = -15V and I_D = -3A. This value determines minimum gate driver current needed for target switching speed in high-frequency applications.
