Product details
Overview
DMP3097LQ-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -30V VDSS, 65mΩ RDS(ON) @ VGS = -10V, and -3.9A continuous drain current at TA = +25°C. It serves as a high-efficiency load switch or synchronous rectifier in low-voltage DC-DC converters and LED backlighting circuits.
For engineers reviewing the DMP3097LQ-13 datasheet, DMP3097LQ-13 pinout, DMP3097LQ-13 application, or DMP3097LQ-13 equivalent, key selection criteria include gate threshold voltage (-1.0 to -2.1V), low input capacitance (563pF Ciss), fast switching times (10ns tD(ON)), AEC-Q101 qualification, and SOT23 thermal performance (RθJA = 123°C/W on FR-4).
Technical Context
This MOSFET operates in enhancement mode with negative gate control logic, requiring VGS ≤ -1.0V to initiate conduction and fully turning on at VGS = -10V. Its low RDS(ON) and 9.5Ω gate resistance support efficient power switching in compact, thermally constrained layouts.
The device integrates an intrinsic body diode with VSD = -0.85V @ IS = -2.7A and exhibits normalized RDS(ON) variation of <1.4× across -55°C to +150°C junction temperature, enabling stable operation in automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - Maximum blocking voltage before avalanche breakdown; defines safe operating range in 24V automotive or 28V industrial rails. |
| RDS(ON) | 65mΩ @ VGS = -10V - Conduction loss of 250mW at 2A load; enables >95% efficiency in 5V/3A buck converter output stage. |
| ID (max) | -3.9A @ TA = +25°C - Continuous current capability limited by 1.0W power dissipation on standard FR-4 PCB. |
| VGS(TH) | -1.0 to -2.1V - Ensures reliable turn-on with 3.3V logic-level gate drive; compatible with microcontroller GPIO without level-shifting. |
| Ciss | 563pF - Low input capacitance reduces gate drive power and speeds up switching transitions in high-frequency (>500kHz) converters. |
| tD(ON) | 10ns - Short turn-on delay minimizes overlap conduction loss in synchronous rectification topologies. |
| Qg | 13.4nC @ VGS = -10V - Total gate charge determines required driver peak current (e.g., 1.34A for 10ns rise time). |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with 3 terminals, 0.008g mass, UL 94V-0 flammability rating, and moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for P-channel conduction | Connected to higher potential rail (e.g., VIN) in high-side switch configuration; ties to ground in low-side synchronous rectifier. |
| 2 (Gate) | Control electrode for channel formation | Receives negative bias relative to source; requires robust ESD protection due to ±20V VGSS rating and sub-100nA leakage. |
| 3 (Drain) | Main current-carrying terminal | Connects to load or output node; handles pulsed currents up to -20A; body diode anode is internally tied to source. |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | VGS(TH) down to -1.0V ensures full enhancement with 3.3V logic drivers, eliminating need for external level shifters in portable systems. |
| Fast switching speed | 10ns turn-on delay and 2.3ns rise time reduce switching losses in high-frequency DC-DC converters operating above 1MHz. |
| AEC-Q101 qualification | Validated for automotive applications including infotainment power supplies and ADAS camera modules with PPAP documentation support. |
| Green packaging | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets automotive OEM environmental requirements and RoHS 3 compliance. |
| Low input/output leakage | ±100nA gate leakage and -800nA drain leakage at -30V enable ultra-low standby power in always-on battery-powered subsystems. |

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 @ VGS = -4.5V; higher Ciss (720pF); same SOT23 package | Better conduction efficiency below 3A but slower switching due to higher capacitance | Select when lowest RDS(ON) at 3.3V gate drive is critical and switching frequency <300kHz. |
| SI2301DDS-T1-BE3 | RDS(ON) = 115mΩ @ VGS = -4.5V; lower Qg (4.5nC); AEC-Q101 not claimed | Lower gate drive power but higher conduction loss; no automotive qualification | Prefer for cost-sensitive consumer electronics where AEC-Q101 is unnecessary and gate drive current is severely limited. |
Compared with DMG3415L-7, DMP3097LQ-13 trades 100pF higher input capacitance for guaranteed AEC-Q101 compliance and tighter VGS(TH) distribution; versus SI2301DDS-T1-BE3, it delivers 43% lower RDS(ON) at -4.5V with documented automotive process control.

FAQ
What is the maximum junction temperature for continuous operation?
The DMP3097LQ-13 has a specified operating junction temperature range of -55°C to +150°C. Continuous operation at TJ = +150°C is permitted only when power dissipation remains within the derated limit defined by RθJA = 123°C/W on standard FR-4 PCB, corresponding to ≤0.81W at ambient 25°C.
Is this MOSFET suitable for reverse polarity protection?
Yes - the DMP3097LQ-13 is commonly used in reverse polarity protection circuits with source connected to input and drain to load. Its -30V VDSS rating supports 24V systems, and its low RDS(ON) ensures minimal voltage drop (<80mV at 1.2A), preserving system efficiency without requiring external diodes.
Does the SOT23 package require special PCB layout considerations?
Yes - the SOT23 footprint must follow Diodes' recommended pad layout (2.0mm × 0.8mm copper area for drain, 1.35mm × 0.9mm for source) to achieve the published RθJA of 123°C/W. Insufficient copper pour increases thermal resistance by >40%, risking premature thermal shutdown in sustained 3A operation.
How does the body diode forward voltage affect synchronous rectification?
The intrinsic body diode has VSD = -0.85V @ -2.7A, which sets the minimum forward conduction loss during dead-time intervals. In synchronous rectification, this value directly impacts light-load efficiency; pairing with a controller that minimizes dead time reduces reliance on the body diode and improves overall conversion efficiency by up to 1.8%.
