Product details
Overview
DMG2307LQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -30V VDSS, 90mΩ RDS(ON) at VGS = -10V and -3.8A ID (TA = +25°C), AEC-Q101 qualified for automotive load switching applications.
For engineers reviewing the DMG2307LQ datasheet, DMG2307LQ pinout, DMG2307LQ application, or DMG2307LQ equivalent, this part supports high-efficiency power management in portable and automotive systems where low gate charge (8.2nC @ VGS = -10V), fast switching (tF = 13.4ns), and thermally robust operation (RθJA = 94°C/W with thermal vias) are critical.
Technical Context
This MOSFET operates as a single-polarity load switch with gate-threshold voltage VGS(TH) ranging from -1.0V to -3.0V, enabling reliable turn-on with standard logic-level drive (e.g., 3.3V/5V microcontroller outputs via level-shifting). Its low input capacitance (Ciss = 371.3pF) and gate resistance (Rg = 17Ω) support clean, controlled edge transitions.
The device integrates an intrinsic body diode with VSD = -0.75V at IS = -1A, suitable for reverse-polarity protection and synchronous rectification in low-duty-cycle DC-DC topologies. Thermal performance is validated under two PCB conditions: 0.76W PD on minimal FR-4 and 1.36W PD on 2oz copper with thermal vias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - Maximum drain-source blocking voltage before avalanche conduction begins. |
| RDS(ON) | 90mΩ @ VGS = -10V, ID = -2.5A - On-resistance determines conduction loss in load-switching paths. |
| ID (max) | -3.8A @ TA = +25°C, VGS = -10V - Continuous current rating defining safe steady-state load capability. |
| Qg | 8.2nC @ VGS = -10V - Total gate charge directly impacts driver power and switching transition time. |
| tF | 13.4ns - Fall time defines how quickly the MOSFET transitions from ON to OFF under specified test conditions. |
| TJ range | -55°C to +150°C - Junction temperature operating window supporting under-hood automotive environments. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with 3 terminals, 0.08g mass, UL 94V-0 rated molding compound, 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., battery positive); body diode anode. |
| 2 (Gate) | Control electrode for channel formation | Receives negative bias relative to source to enable conduction; low Ciss eases driving. |
| 3 (Drain) | Current output terminal | Connected to load; body diode cathode; withstands -30V reverse voltage when off. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at logic-level drive | 134mΩ @ VGS = -4.5V enables use with 5V/3.3V controllers without external level shifters. |
| Fast switching with low Qgd | 1.2nC gate-drain charge minimizes Miller plateau duration and improves turn-off control. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules and infotainment power rails. |
| Green packaging | Halogen- and antimony-free, RoHS 3 compliant (Br+Cl <1500ppm, Sb <1000ppm), matte tin finish. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMP3165LQ | Higher VDSS (-60V), lower RDS(ON) (60mΩ @ -10V), but larger Qg (12.5nC) | Better suited for 48V industrial systems; slower switching due to higher gate charge | Select when higher voltage margin or lower conduction loss outweighs switching speed requirements. |
| SI2307DS | Same SOT23 package, -30V rating, but RDS(ON) = 110mΩ @ -4.5V and no AEC-Q101 qualification | Cost-optimized for consumer electronics; not validated for automotive temperature or reliability stress tests | Choose for non-automotive applications where qualification overhead is unnecessary and cost is primary. |
Compared with DMP3165LQ and SI2307DS, DMG2307LQ uniquely balances automotive qualification, 4.5V logic compatibility, and 13.4ns fall time-making it optimal for space-constrained, safety-aware 12V/24V load switching where thermal vias are feasible.

FAQ
Is DMG2307LQ suitable for 3.3V GPIO-driven switching?
Yes. With VGS(TH) down to -1.0V and RDS(ON) = 134mΩ at VGS = -4.5V, it fully enhances using a 3.3V microcontroller's inverted output (e.g., via open-drain buffer or pull-up to 5V). No external level shifter is required for moderate-current loads up to 2.5A.
What is the maximum continuous current at 85°C ambient?
At TA = +85°C, the DMG2307LQ supports -2.5A continuous drain current when mounted on a 2oz FR-4 board with thermal vias (PD = 1.36W, RθJA = 94°C/W). Derating follows linear junction-to-ambient thermal law: ID decreases by ~12% per 25°C rise above 25°C ambient.
Does DMG2307LQ include integrated ESD protection?
No. The DMG2307LQ does not integrate on-die ESD protection structures beyond standard process-level HBM tolerance (per JESD22-A114). External TVS diodes or RC filters are recommended for I/O lines exposed to user-accessible ports or cable interfaces.
Can DMG2307LQ replace N-channel MOSFETs in high-side configurations?
Yes-but only with appropriate gate drive. As a P-channel device, it simplifies high-side switching versus N-channel alternatives that require bootstrap or isolated gate drivers. Its -30V rating and logic-compatible threshold make it a direct replacement where negative gate bias is feasible and efficiency at low VGS is prioritized.
