Product details
Overview
DMP510DLQ 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 automotive-grade analog/power switch in signal routing and power management circuits, qualified to AEC-Q101 with PPAP support.
For engineers reviewing the DMP510DLQ datasheet, DMP510DLQ pinout, DMP510DLQ application, or DMP510DLQ equivalent, key selection criteria include gate threshold voltage (-0.8 to -2.0V), low input capacitance (40pF Ciss), fast switching (4ns tD(ON)), thermal resistance (180°C/W under enhanced layout), 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 analog switching and low-side power gating.
The device uses planar DMOS technology with optimized channel geometry for stable RDS(ON) across -55°C to +150°C junction temperature, and features low gate charge (0.5nC Qg) to minimize drive power in battery-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -50V - Maximum blocking voltage before avalanche breakdown; enables use in 24V automotive supply rails with margin. |
| RDS(ON) | 9.5Ω @ VGS = -5V - On-resistance determines I²R loss and self-heating in low-current switching (<200mA). |
| ID (cont.) | -196mA @ TA = +25°C - Continuous current rating under standard FR-4 PCB layout; derates to -156mA at +70°C ambient. |
| VGS(TH) | -0.8 to -2.0V - Gate threshold range ensures reliable turn-on with 3.3V or 5V logic-level drivers in automotive microcontroller interfaces. |
| Ciss | 40pF - Input capacitance affects gate drive timing and EMI in high-frequency switching; compatible with low-drive-strength GPIOs. |
| tD(ON) | 4ns - Turn-on delay time measured at VDD = -30V, enabling sub-10ns edge transitions in digital enable/control paths. |
| RθJA | 180°C/W - Thermal resistance with 1-inch² copper pad; defines junction-to-ambient temperature rise per watt dissipated. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with matte tin terminals, UL 94V-0 flammability rating, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for P-channel conduction | Connected to higher potential rail (e.g., VBAT); referenced for gate drive and body diode cathode. |
| 2 (Gate) | Control terminal for channel formation | Receives negative bias relative to source to enable conduction; low Ciss reduces drive energy requirements. |
| 3 (Drain) | Current output terminal | Switches load to ground or lower-potential node; body diode anode connects internally to this terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | VGS(TH) down to -0.8V enables direct interface with 3.3V automotive MCUs without level-shifting circuitry. |
| Low input capacitance | 40pF Ciss minimizes gate drive current and propagation delay in high-speed enable/disable control signals. |
| Fast switching speed | 4ns turn-on delay and 13.8ns fall time support precise timing in pulse-width modulated power gating. |
| AEC-Q101 qualification | Validated for automotive use with PPAP documentation and manufacturing in IATF 16949-certified facilities. |
| Green construction | Halogen- and antimony-free, lead-free, RoHS 3 compliant - meets automotive environmental compliance mandates. |
Applications
| Automotive Body Control Module | USB Port Power Switching |
|---|---|

IC Role / Device Role / Timing Role: High-voltage interface switch protecting downstream transceivers from surge-induced latch-up. Use Value: -50V VDSS and 1.2A pulsed current rating allow safe clamping of transient overvoltages without external TVS dependency. |
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 |
|---|---|---|---|
| DMN5L06LK-7 | Lower VDSS (-30V), lower RDS(ON) (3.5Ω @ -4.5V), SOT23 package | Not AEC-Q101 qualified; suitable for non-automotive industrial use only | Select when higher current (>300mA) and lower on-resistance are prioritized over automotive qualification. |
| SI2301DS-T1-BE3 | Higher VDSS (-20V), higher RDS(ON) (120mΩ @ -2.5V), same SOT23 footprint | Qualified to AEC-Q101 but rated for lower voltage rails (12V systems only) | Choose for cost-sensitive 12V automotive applications where gate drive is limited to -2.5V. |
Compared with DMN5L06LK-7 and SI2301DS-T1-BE3, DMP510DLQ uniquely balances -50V blocking capability, AEC-Q101 compliance, and 3.3V-compatible gate threshold-making it optimal for 24V automotive power switches requiring robust transient immunity and MCU-level control.

FAQ
What is the maximum operating junction temperature for DMP510DLQ?
The DMP510DLQ has a specified operating junction temperature range of -55°C to +150°C. This rating is validated per AEC-Q101 stress testing and applies under all electrical operating conditions defined in the datasheet, including continuous and pulsed drain current limits.
Can DMP510DLQ be used with 3.3V microcontroller GPIOs?
Yes - its gate threshold voltage range of -0.8V to -2.0V allows full enhancement with 3.3V logic when the source is tied to a higher rail (e.g., 5V or 12V), producing sufficient VGS swing. At VS = 5V and VGPIO = 0V, VGS = -5V ensures robust conduction.
Is DMP510DLQ suitable for reverse polarity protection?
No - as a P-channel MOSFET with source connected to the input rail, it lacks intrinsic reverse-blocking capability when placed in series with the supply. For reverse polarity protection, it must be configured as a high-side switch with gate driven below source potential, which requires additional circuitry beyond basic placement.
Does DMP510DLQ have a built-in ESD protection diode?
No - the datasheet does not specify integrated ESD protection structures. The device exhibits ±30V gate-source voltage rating and ±100nA gate leakage, indicating standard MOSFET gate oxide without dedicated on-chip ESD clamps. External TVS or RC filtering is recommended for board-level ESD immunity.
