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 is AEC-Q101 qualified, PPAP-capable, and designed for automotive power management and interfacing switches.
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 device operates as a single P-channel switch in high-side configuration, leveraging its negative gate threshold and low RDS(ON) to minimize conduction loss in 12V automotive systems. Its -30V breakdown rating supports operation across standard vehicle battery transients (e.g., load dump up to +35V).
Thermal performance is defined by two RθJA values: 158°C/W on minimal FR-4 pad layout and 100°C/W with 1-inch² copper pour - enabling design flexibility between cost-sensitive and thermally demanding applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V: Withstands automotive load-dump transients without avalanche failure. |
| RDS(ON) | 70mΩ @ VGS = -10V: Enables <100mW conduction loss at 3.4A, reducing thermal stress in compact layouts. |
| ID (continuous) | -3.4A @ TA = +25°C: Supports medium-power loads such as LED drivers, ECU power rails, and sensor biasing. |
| Ciss | 366pF: Low input capacitance enables fast turn-on with minimal gate drive energy, critical for PWM control. |
| td(on) | 3.2ns: Short delay time allows high-frequency switching (>1MHz) in DC-DC pre-regulators and active clamping circuits. |
| VGS(TH) | -1.0 to -2.1V: Ensures reliable turn-on with standard 3.3V or 5V logic-level gate drivers in automotive microcontrollers. |
| RθJA | 100°C/W (with 1"² copper): Limits junction temperature rise to ≤100°C at 0.8W dissipation, supporting industrial-grade reliability. |
Pinout & Package
Package: SOT23 - surface-mount, 3-terminal plastic package with matte tin annealed terminals; moisture sensitivity level 1 per J-STD-020; weight ≈0.008g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for P-channel conduction | Connected to higher potential rail (e.g., battery +12V); referenced for gate control and internal body diode cathode. |
| 2 (Gate) | Control terminal for channel formation | Receives negative voltage relative to source to enable conduction; low Ciss reduces driver loading. |
| 3 (Drain) | Current output terminal | Connects to load; body diode anode enables reverse-current protection in high-side switch configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | VGS(TH) down to -1.0V ensures full enhancement with 3.3V MCU GPIOs in automotive modules. |
| Fast switching speed | 3.2ns turn-on delay + 8.2ns rise time minimizes switching loss in 500kHz–1MHz DC-DC stages. |
| Low input/output leakage | IDSS ≤ -800nA at -30V and IGSS ≤ ±100nA support long-term standby power integrity in always-on ECUs. |
| AEC-Q101 qualification | Validated for automotive temperature range (-55°C to +150°C) and mechanical stress per IATF 16949 processes. |
| Green packaging | Halogen- and antimony-free molding compound (Br+Cl <1500ppm, Sb <1000ppm) meets global environmental compliance mandates. |
Applications

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 | RDS(ON) = 45mΩ @ -4.5V (lower), but VDSS = -20V (reduced transient margin) | Better suited for 5V logic systems; insufficient for 12V automotive load dump immunity | Select only if operating strictly within 5V supply domains and thermal budget permits lower RDS(ON). |
| AO3401 | RDS(ON) = 85mΩ @ -4.5V (higher), no AEC-Q101 qualification, RθJA = 160°C/W | Limited to consumer/industrial use; lacks PPAP documentation and IATF 16949 traceability | Acceptable for non-automotive prototypes or cost-sensitive non-safety designs where qualification is not required. |
Compared with DMG3415L-7 and AO3401, DMP3096LQ uniquely balances -30V robustness, AEC-Q101 compliance, and 70mΩ RDS(ON) at -10V - making it the only option qualified for production automotive power switches requiring both transient immunity and thermal efficiency.

FAQ
Is DMP3096LQ suitable for high-side switching in 12V automotive systems?
Yes. Its -30V VDSS, AEC-Q101 qualification, and -1.0V to -2.1V gate threshold ensure reliable operation under automotive battery transients and compatibility with 3.3V/5V microcontroller outputs. The SOT23 package supports compact placement near loads, minimizing parasitic inductance in high-current paths.
What is the maximum power dissipation capability of DMP3096LQ on a standard PCB?
With a 1-inch² copper pour (RθJA = 100°C/W), DMP3096LQ can dissipate up to 1.2W continuously before reaching its 150°C maximum junction temperature at 25°C ambient. At 70°C ambient, derated power drops to ~0.8W - consistent with its specified 0.8W rating on minimal FR-4 layout.
Does DMP3096LQ include an integrated body diode, and what is its forward voltage?
Yes. As a standard P-channel MOSFET, it includes an inherent body diode with VSD = -0.8V to -1.26V at IS = -2.7A and TA = +25°C. This diode provides reverse-current protection in high-side configurations and enables freewheeling in inductive load switching.
Can DMP3096LQ be used with 3.3V logic-level gate drive?
Yes. Its VGS(TH) range of -1.0V to -2.1V guarantees full enhancement with 3.3V logic when referenced to source (i.e., VGS = -3.3V). At that drive level, RDS(ON) is typically 130mΩ, sufficient for ≤2.5A loads with acceptable conduction loss.
