Product details
Overview
DMP2109UVTQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET qualified to AEC-Q101 for automotive use, featuring -20V VDSS, 80mΩ RDS(ON) @ VGS = -4.5V, and -3.7A continuous drain current at TA = +25°C; deployed in power management and general-purpose interfacing switches.
For engineers reviewing the DMP2109UVTQ datasheet, DMP2109UVTQ pinout, DMP2109UVTQ application, or DMP2109UVTQ equivalent, key selection criteria include gate threshold voltage (-0.45V to -1.0V), low input capacitance (443pF Ciss), thermal resistance (77°C/W RθJA with copper plate), and TSOT26 package compatibility in space-constrained automotive PCB layouts.
Technical Context
This MOSFET operates as a low-side load switch with fully specified gate-drive compatibility down to -2.5V, enabling direct interface with 3.3V and 5V logic controllers. Its -1.0V maximum VGS(TH) ensures reliable turn-on under marginal supply conditions, while the 47pF Crss supports fast switching with controlled dV/dt.
The device integrates a body diode with -0.7V typical VSD at -1A and 8.3ns reverse recovery time, supporting synchronous rectification and flyback energy recirculation in DC-DC converters. Thermal performance is validated under two mounting conditions: 105°C/W (FR-4, minimal pad) and 77°C/W (1-inch copper plate).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Maximum drain-source blocking voltage for 12V automotive rail protection |
| RDS(ON) | 80mΩ @ VGS = -4.5V - Enables ≤300mW conduction loss at 3.7A load current |
| VGS(TH) | -0.45V to -1.0V - Ensures full enhancement with 3.3V GPIO or microcontroller outputs |
| Ciss | 443pF - Limits gate drive power requirement to <1µJ per 1MHz switching cycle |
| tF | 9.5ns - Supports >10MHz PWM operation with minimal switching transition overlap |
| RθJA | 77°C/W - Allows 1.0W continuous dissipation at TA ≤ +73°C with 1-inch copper |
| Qg | 6.0nC - Compatible with low-current gate drivers (e.g., TC4427, UCC27517) |
Pinout & Package
Package: TSOT26 - 6-pin ultra-thin surface-mount package (2.9mm × 1.6mm × 0.6mm), RoHS-compliant, halogen-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (D) | Drain | Main high-current path; connected to load side of switched 12V rail |
| 2 (D) | Drain | Internally paralleled with Pin 1 for lower inductance and thermal spreading |
| 3 (G) | Gate | Control input; requires no external pull-up due to negative VGS(TH) |
| 4 (D) | Drain | Third drain terminal; enhances current sharing and thermal derating margin |
| 5 (D) | Drain | Fourth drain terminal; reduces package-level RDS(ON) contribution by ~15% |
| 6 (S) | Source | Reference node for gate drive; tied to system ground or battery return |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| DMP2035UVTQ | VDSS = -20V, RDS(ON) = 100mΩ @ -4.5V, Qg = 4.5nC, same TSOT26 package | Higher RDS(ON) increases conduction loss by 25% at 3A; lower Qg improves 10–20MHz switching efficiency | Select when gate drive current is limited and thermal margin exceeds 15°C; not recommended for >3A continuous loads |
| DMN2011UVTQ | N-channel counterpart, VDSS = +20V, RDS(ON) = 45mΩ @ +4.5V, requires high-side driver or charge pump | Enables lower RDS(ON) but adds complexity; unsuitable for direct low-side ground-referenced switching | Choose only when topology permits N-channel implementation and board space allows driver IC integration |
Compared with DMP2035UVTQ, DMP2109UVTQ delivers 20% lower conduction loss at 3.7A while retaining identical footprint and AEC-Q101 qualification; versus DMN2011UVTQ, it eliminates gate drive complexity but trades 35mΩ lower RDS(ON) for system-level simplicity and reduced BOM count.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The DMP2109UVTQ has a rated junction temperature range of -55°C to +150°C. For continuous operation, the absolute maximum TJ is +150°C. Derating begins at TA = +70°C per the datasheet's ID vs. TA curves, and thermal design must ensure TJ remains below +150°C under worst-case ambient and power dissipation conditions using the specified 77°C/W RθJA value with 1-inch copper.
Can this MOSFET be used in a high-side switch configuration?
No - the DMP2109UVTQ is a P-channel device optimized for low-side switching where the source connects to the positive rail and the drain drives the load to ground. High-side use would require gate voltage above the source (i.e., >+12V), which contradicts its -10V VGS rating and lacks integrated charge pump support. It is not rated or characterized for high-side operation.
Is the TSOT26 package compatible with standard SOT-23-6 reflow profiles?
Yes - the TSOT26 package uses the same JEDEC-standard reflow profile as SOT-23-6, with peak temperature up to 260°C for 30 seconds. Its moisture sensitivity level 1 rating means floor life is unlimited at ≤30°C/60% RH, eliminating bake requirements prior to assembly. The tin-finished copper leadframe ensures solderability per MIL-STD-202, Method 208.
Does the body diode support synchronous rectification in buck converters?
Yes - the integrated body diode has a typical forward voltage of -0.7V at -1A and 8.3ns reverse recovery time, making it suitable for discontinuous conduction mode (DCM) buck converter freewheeling paths. However, its 2.0nC QRR and lack of soft-recovery characteristics limit use in high-frequency (>2MHz) or high-efficiency synchronous designs where Schottky or GaN co-packaged solutions are preferred.
