Product details
Overview
DMP510DLQ-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -50V VDSS, 9.5Ω RDS(ON) at VGS = -5V, and -196mA continuous drain current at +25°C. It serves as a low-power analog or interface switch in automotive signal routing and power management circuits, qualified to AEC-Q101 with PPAP support.
For engineers reviewing the DMP510DLQ-7 datasheet, DMP510DLQ-7 pinout, DMP510DLQ-7 application, or DMP510DLQ-7 equivalent, key selection criteria include gate threshold voltage (-0.8 to -2.0V), low input capacitance (40pF Ciss), fast switching (tD(OFF) = 39.7ns), thermal resistance (240°C/W RθJA), and SOT23 package compatibility.
Technical Context
This MOSFET operates in enhancement mode with negative gate control logic, requiring VGS ≤ -0.8V to initiate conduction and fully turning on at VGS = -5V. Its body diode supports reverse-current paths in bidirectional signal switching applications.
Designed for automotive-grade reliability, it features low gate charge (0.5nC Qg), low leakage (±100nA IGSS), and stable RDS(ON) over temperature (±20% variation from -55°C to +150°C), enabling robust operation in engine control and infotainment subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -50V - Withstands up to 50V reverse drain-source voltage before breakdown, suitable for 12V/24V automotive rail switching. |
| RDS(ON) | 9.5Ω max @ VGS = -5V - Enables <100mW conduction loss at 100mA, minimizing self-heating in space-constrained PCB layouts. |
| ID (continuous) | -196mA @ TA = +25°C - Supports low-current load switching such as LED biasing, sensor enable lines, or microcontroller I/O buffering. |
| VGS(TH) | -0.8 to -2.0V - Ensures reliable turn-on from standard 3.3V or 5V logic outputs with margin for voltage drop across series resistors. |
| Ciss | 40pF - Limits gate drive current demand and enables clean edge transitions in sub-10MHz digital switching applications. |
| tD(OFF) | 39.7ns - Allows rapid disable timing for pulse-width modulation or fault isolation in safety-critical subsystems. |
| RθJA | 240°C/W - Requires minimal copper area (FR-4, 2oz) for thermal management, compatible with dense SOT23 routing. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with matte tin terminals, UL 94V-0 flammability rating, moisture sensitivity level 1, and 0.008g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D (Drain) | High-side current sink node | Connected to positive supply rail in high-side switch configurations; handles full load current path. |
| G (Gate) | Control input | Accepts negative voltage relative to source to modulate channel conductivity; low Ciss reduces drive power. |
| S (Source) | Reference node / return path | Biased at system ground or higher potential; defines VGS reference and carries body diode forward current. |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | VGS(TH) down to -0.8V enables direct drive from 3.3V microcontrollers without level-shifting circuitry. |
| Low input capacitance | 40pF Ciss minimizes gate drive energy and propagation delay in high-frequency enable/disable sequences. |
| Fast switching speed | 39.7ns turn-off delay supports PWM frequencies >1MHz in precision analog multiplexing or power sequencing. |
| AEC-Q101 qualification | Validated for automotive use with PPAP documentation and IATF 16949 manufacturing compliance. |
| Green construction | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb), fully RoHS 3 compliant for global vehicle deployment. |
Applications
| Automotive Sensor Interface | Infotainment Power Sequencing |
|---|---|
Use Scenario: Isolating analog sensor signals (e.g., temperature, pressure) from ECU inputs during sleep mode. IC Role / Device Role / Timing Role: Analog switch controlling signal path integrity via gate-controlled channel conduction. Use Value: Low RDS(ON) preserves signal fidelity; low leakage (<1µA IDSS) prevents DC offset drift in high-impedance sensor nodes. |

Use Scenario: Controlling small solenoids or relays in door lock actuators or mirror adjustment circuits. IC Role / Device Role / Timing Role: General-purpose interfacing switch handling intermittent 100–200mA loads. Use Value: -50V VDSS withstands load-dump transients; low Qg (0.5nC) reduces MCU GPIO stress during repeated switching. |
Use Scenario: Driving status LEDs in instrument clusters or center consoles with dimming capability. IC Role / Device Role / Timing Role: Current-limiting analog switch regulating LED brightness via PWM-modulated gate voltage. Use Value: Stable RDS(ON) vs. temperature ensures consistent LED intensity across cabin operating range (-40°C to +105°C). |
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 | RDS(ON) = 45mΩ @ VGS = -4.5V; higher current rating (-4.2A), larger SO-8 package | Requires PCB redesign for higher-power loads; not SOT23-compatible | Select when >200mA continuous current or lower on-resistance is required; not drop-in for space-constrained designs. |
| AO3401 | RDS(ON) = 55mΩ @ VGS = -4.5V; non-AEC-Q101; RθJA = 120°C/W | Lacks automotive qualification and PPAP support; higher thermal performance but no change control | Use only in non-automotive industrial or consumer applications where qualification is not mandated. |
Compared with DMG2305U-7 and AO3401, DMP510DLQ-7 uniquely balances AEC-Q101 compliance, SOT23 footprint, and sub-200mA switching capability-making it optimal for cost-sensitive, space-limited automotive signal routing where qualification and traceability are mandatory.

FAQ
Is DMP510DLQ-7 suitable for 3.3V logic-level gate drive?
Yes. Its gate threshold voltage range of -0.8V to -2.0V ensures reliable turn-on with 3.3V microcontroller outputs driving the gate negative relative to source. At VGS = -3.3V, RDS(ON) remains below 15Ω per Figure 3, supporting functional switching without external level shifters.
What is the maximum safe operating temperature for continuous use?
The device supports continuous operation up to +150°C junction temperature. With RθJA = 240°C/W on standard FR-4 board, ambient temperature must be limited to +85°C at 196mA to maintain TJ ≤ 150°C. Derating is required above that current or ambient.
Does DMP510DLQ-7 include integrated ESD protection?
No. The datasheet does not specify on-chip ESD protection structures. External TVS diodes or series resistors are recommended for gate protection in environments with >2kV HBM risk, especially in automotive harness-connected applications.
Can DMP510DLQ-7 replace N-channel MOSFETs in high-side configurations?
No. As a P-channel device, it is inherently suited for high-side switching with source tied to VCC. Replacing an N-channel high-side switch would require gate drive circuitry capable of generating a negative voltage relative to source-unlike N-channel bootstrap or charge-pump solutions.
