Product details

Overview

DMP3045LVTQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -30V V_DSS, 42 mΩ R_DS(ON) at V_GS = -10V, and -5.4A continuous drain current at T_A = +25°C. It is AEC-Q101 qualified, PPAP-capable, and designed for automotive power-management functions including backlighting and DC-DC converters.

For engineers reviewing the DMP3045LVTQ datasheet, DMP3045LVTQ pinout, DMP3045LVTQ application, or DMP3045LVTQ equivalent, key selection criteria include its low on-resistance at -4.5V gate drive, fast switching speed (t_F = 26 ns), ESD-protected gate, TSOT26 package thermal performance (R_θJA = 78 °C/W with enhanced pad layout), and automotive-grade reliability certification.

Technical Context

This MOSFET operates as a high-side load switch in automotive power rails, leveraging its negative threshold voltage (-1 to -2.1 V) and robust avalanche rating (E_AS = 30 mJ). Its low input capacitance (C_iss = 749 pF) and gate charge (Q_g = 14.3 nC at V_GS = -10V) support efficient PWM control in compact DC-DC topologies.

The device integrates an intrinsic body diode with V_SD = -0.7 to -1.2 V at I_S = -1 A and exhibits stable R_DS(ON) over temperature (±15% variation from -55°C to +150°C at fixed V_GS). Thermal resistance is optimized via TSOT26's exposed drain pad and low R_θJC = 19.6 °C/W.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-30 V - Maximum blocking voltage in high-side switch configurations without breakdown
R_DS(ON)	42 mΩ @ V_GS = -10V, I_D = -4.9A - Enables <125 mW conduction loss at 5 A load
I_D (max)	-5.4 A @ T_A = +25°C - Supports automotive LED backlight drivers up to 12 W per channel
Q_g	14.3 nC @ V_GS = -10V - Allows fast turn-on with <1 μs delay using standard gate drivers
t_F	26 ns - Minimizes switching losses in 500 kHz–1 MHz DC-DC converters
E_AS	30 mJ - Withstands inductive energy spikes in motor driver or solenoid control circuits
R_θJA	78 °C/W (enhanced layout) - Limits junction rise to <120°C at 1.2 W dissipation in automotive ambient

Pinout & Package

Package: TSOT26 - 6-pin thermally enhanced surface-mount package with exposed drain pad for improved heat dissipation and low-profile mounting (max height 1.00 mm).

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control terminal; accepts -4.5V to -10V logic-level drive; ESD-protected (HBM >2 kV)
2 (S)	Source	Reference node for gate drive; connects to system ground or floating rail in high-side configuration
3 (D)	Drain	Main current path output; tied to exposed pad for thermal conduction and low-inductance routing
4 (D)	Drain	Second drain connection; electrically identical to Pin 3; enhances current handling and thermal transfer
5 (S)	Source	Redundant source terminal; reduces bond-wire resistance and improves current sharing
6 (G)	Gate	Secondary gate connection; minimizes gate loop inductance for high-frequency switching stability

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive underhood environments (T_J = -40°C to +150°C, HTOL, TC, HTRB)
Low R_DS(ON) at -4.5V	65 mΩ enables direct interface with 3.3V/5V microcontroller GPIOs without level-shifting
Fast switching (t_D(off) = 27.5 ns)	Reduces dead-time losses in synchronous buck controllers operating above 300 kHz
Exposed drain pad	Provides <0.5°C/W thermal path to PCB copper, lowering R_θJA by 25% vs. standard SOT23
Halogen- and antimony-free	Meets automotive OEM green material requirements (<900 ppm Br+Cl, <1000 ppm Sb)

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3045LVTQ-7	N-channel counterpart with same R_DS(ON) and package; requires high-side gate driver or bootstrap circuitry	Suitable only where low-side switching is acceptable or driver ICs are available	Select only when topology permits N-channel use and gate drive complexity is acceptable
AO3401	Higher R_DS(ON) (60 mΩ @ -4.5V); not AEC-Q101 qualified; R_θJA = 110 °C/W	Limited to non-automotive industrial or consumer DC-DC designs with relaxed thermal and reliability requirements	Use only for cost-sensitive, non-automotive applications with derated current (<3 A)

Compared with DMN3045LVTQ-7, DMP3045LVTQ eliminates gate driver overhead in high-side configurations; versus AO3401, it delivers 30% lower conduction loss and certified automotive robustness-critical for safety-critical lighting and power management systems.

FAQ

What is the maximum continuous drain current at 100°C ambient temperature?

At T_A = +100°C, the DMP3045LVTQ supports -3.2 A continuous drain current with V_GS = -4.5V and -4.3 A with V_GS = -10V, based on thermal derating curves in the datasheet (DS43845 Rev. 3-2, page 2). This reflects junction temperature limiting to 150°C using the 78 °C/W R_θJA value with enhanced PCB layout.

Does this MOSFET require a gate resistor for safe operation?

A gate resistor (typically 5–22 Ω) is recommended to dampen ringing and limit peak gate current during fast switching, especially in high-frequency DC-DC converters. The device's low Q_g (14.3 nC) and Crss (79 pF) make it susceptible to oscillation without proper gate control, but no minimum resistor is mandated for basic on/off operation.

Can DMP3045LVTQ be used in parallel with identical units?

Yes-its positive temperature coefficient of R_DS(ON) (increasing with junction temperature) enables inherent current sharing. Parallel operation requires matched layout symmetry, identical gate drive paths, and shared thermal mass to maintain <5°C inter-device ΔT, as confirmed by thermal characterization in Figure 7 of DS43845.

Is the TSOT26 package lead (Pb)-free and RoHS-compliant?

Yes-the DMP3045LVTQ uses matte tin-annealed terminals over copper lead-frame and is fully RoHS 3 compliant (2015/863/EU), with no intentionally added lead, halogens, or antimony. It meets UL 94V-0 flammability rating and J-STD-020 moisture sensitivity Level 1.
