Product details
Overview
DMP3096LQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -30V VDSS, 70mΩ RDS(ON) at VGS = -10V, and -3.4A continuous drain current at TA = +25°C; it serves as a low-side power switch in automotive body control modules requiring AEC-Q101 qualification and PPAP support.
For engineers reviewing the DMP3096LQ datasheet, DMP3096LQ pinout, DMP3096LQ application, or DMP3096LQ equivalent, key selection criteria include gate threshold voltage (-1.0 to -2.1V), low-input capacitance (366pF Ciss), fast switching (3.2ns td(on)), thermal resistance (100°C/W RθJA on 1"² copper), and SOT23 package compatibility with space-constrained PCB layouts.
Technical Context
This MOSFET operates in enhancement mode with negative gate control logic, enabling direct interface with 3.3V/5V microcontroller GPIOs due to its low |VGS(TH)| and guaranteed turn-on at VGS = -4.5V. Its internal body diode supports reverse-current protection in load-switching topologies.
The device uses planar trench-gate technology to achieve stable RDS(ON) over temperature (±15% variation from -55°C to +150°C) and low gate charge (3.8nC at VGS = -4.5V), reducing drive power and improving efficiency in high-frequency PWM applications up to 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - Maximum blocking voltage for 12V automotive battery rail transients (ISO 7637-2 Pulse 1/2a). |
| RDS(ON) | 70mΩ @ VGS = -10V - Enables ≤240mW conduction loss at -3.4A, suitable for <1W load switches. |
| ID (cont) | -3.4A @ TA = +25°C - Supports typical automotive solenoid, LED, or fan loads without heatsinking. |
| Ciss | 366pF - Low input capacitance reduces gate drive current demand and speeds up switching transitions. |
| td(on) | 3.2ns - Fast turn-on minimizes overlap conduction loss in synchronous buck or OR-ing configurations. |
| RθJA | 100°C/W - Achieved with 1-inch² copper pad; enables 1.2W power dissipation at ambient ≤70°C. |
| Qg | 3.8nC @ VGS = -4.5V - Matches standard logic-level drivers (e.g., TC4427) without external gate resistors. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with matte tin–annealed terminals, moisture sensitivity level 1, and 0.008g mass; compatible with standard reflow profiles and automated pick-and-place.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for P-channel operation | Connected to system ground or higher-potential rail; provides reference for gate drive and body diode cathode. |
| 2 (Gate) | Control electrode for channel formation | Accepts negative VGS relative to source; low Ciss and Qg enable direct MCU GPIO drive. |
| 3 (Drain) | Load connection terminal | Switches negative-side current to load; exposed drain pad improves thermal performance in layout. |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | VGS(TH) = -1.0 to -2.1V ensures reliable turn-on with 3.3V logic systems without level-shifting. |
| Fast switching speed | td(on)/tf = 3.2/13.1ns reduces transition losses in 20–100kHz PWM-controlled lighting or motor drives. |
| Low input/output leakage | IDSS ≤ -800nA and IGSS ≤ ±100nA minimize standby power in always-on automotive modules. |
| AEC-Q101 qualified | Validated for automotive temperature range (-55°C to +150°C) and PPAP documentation support per IATF 16949. |
Applications
| Body Control Module (BCM) | Automotive Lighting Control |
|---|---|
Use Scenario: Switching 12V power to door lock actuators, window lift motors, or mirror heaters in OEM BCM designs. IC Role / Device Role / Timing Role: Low-side load switch controlling ground-return path; operates in DC or pulsed mode with <10ms response requirement. Use Value: 70mΩ RDS(ON) limits voltage drop to <240mV at 3.4A, preserving actuator torque and meeting ISO 16750-2 voltage tolerance. | Use Scenario: Driving LED headlamp positioners or interior ambient lighting strings in AEC-Q101–compliant vehicles. IC Role / Device Role / Timing Role: Constant-current sink switch modulated via PWM; requires fast turn-off to prevent LED ghosting during dimming transitions. Use Value: 13.1ns fall time and 39pF Crss ensure clean edge fidelity at 1kHz–10kHz dimming frequencies without EMI spikes. |
| Engine Control Unit (ECU) Peripherals | Infotainment Power Sequencing |
Use Scenario: Enabling/disabling sensors (e.g., MAP, IAT) or CAN transceiver bias rails during ECU sleep/wake cycles. IC Role / Device Role / Timing Role: Controlled power gate with <1μA leakage; activated by microcontroller GPIO during wake-up sequence. Use Value: -800nA IDSS and ±100nA IGSS keep total sleep current below 5μA, extending battery life in key-off scenarios. | Use Scenario: Sequencing power to display backlight, audio amplifier, and USB-C controller in automotive infotainment head units. IC Role / Device Role / Timing Role: Independent rail switch with controlled slew rate; coordinated via firmware to avoid inrush-induced brownouts. Use Value: 100°C/W RθJA on standard FR-4 allows 1.2W dissipation during 500ms inrush, eliminating need for external thermal relief. |
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 |
|---|---|---|---|
| DMG3415L-7 | RDS(ON) = 45mΩ @ VGS = -4.5V; higher ID = -4.0A; same SOT23 package | Better conduction efficiency at lower VGS, but higher Ciss (520pF) slows switching vs. DMP3096LQ | Select when prioritizing low-loss DC operation over fast PWM; verify gate drive capability for 520pF load. |
| AO3401 | RDS(ON) = 85mΩ @ VGS = -4.5V; non-AEC-Q101; RθJA = 150°C/W | Lacks automotive qualification and thermal performance; suitable only for non-safety-critical consumer designs | Use only in cost-sensitive, non-automotive applications where AEC-Q101 and PPAP are not required. |
Compared with DMG3415L-7 and AO3401, the DMP3096LQ delivers optimal balance of automotive qualification, 70mΩ RDS(ON) at logic-level drive, and 3.2ns td(on)-making it preferred for safety-relevant, space-constrained, and thermally demanding 12V load-switching roles.

FAQ
What is the maximum safe operating junction temperature for DMP3096LQ?
The DMP3096LQ has a specified operating junction temperature range of -55°C to +150°C. Its absolute maximum rating is +150°C, validated under AEC-Q101 stress testing. Thermal design must ensure TJ stays within this limit using the 100°C/W RθJA value measured on a 1-inch² copper pad.
Does DMP3096LQ require a gate resistor for MCU GPIO driving?
No external gate resistor is required when driven directly by 3.3V or 5V microcontroller GPIOs, as its 3.8nC total gate charge and 9.2Ω gate resistance allow full switching within typical MCU output current limits (±20mA). A 10Ω series resistor may be added for EMI suppression if layout permits.
How does the body diode performance impact reverse-current protection?
The integrated body diode has a forward voltage of -0.8 to -1.26V at -2.7A, enabling bidirectional current blocking in back-to-back configurations. When used as a single switch, it provides inherent reverse-polarity protection for downstream loads connected to the drain terminal.
Is DMP3096LQ compliant with RoHS 3 and halogen-free standards?
Yes-the DMP3096LQ is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen-free per Diodes' definition: <900ppm bromine, <900ppm chlorine (<1500ppm total Br+Cl), and <1000ppm antimony. This is verified in the "Green" material certification referenced in DS44770 Rev. 4-2.
