Product details
Overview
DMP2037UFCL-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in a U-DFN1616-6 package, rated for -20V VDSS, 28 mΩ RDS(ON) @ VGS = -4.5V, and -8A continuous drain current at TA = +25°C. It serves as a low-loss load switch in space-constrained power rails for portable electronics and USB-C PD sink circuits.
For engineers reviewing the DMP2037UFCL-7 datasheet, DMP2037UFCL-7 pinout, DMP2037UFCL-7 application, or DMP2037UFCL-7 equivalent, key selection criteria include its low gate threshold (-0.5 to -1.5 V), ESD-protected gate, 806 pF input capacitance, fast turn-on delay (13 ns), and thermal resistance of 114 °C/W on FR-4.
Technical Context
This MOSFET employs a trench-gate process optimized for low RDS(ON) while maintaining robust switching performance. Its gate threshold voltage range (-0.5 to -1.5 V) enables reliable turn-on with standard logic-level drive, and the integrated gate protection diode suppresses transient-induced gate damage.
The device features a thermally enhanced U-DFN1616-6 package with an exposed drain pad, delivering 55 °C/W RθJA under 2 oz copper thermal bias-critical for sustained 6.8 A operation at elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20 V - Maximum blocking voltage before avalanche conduction; defines safe operating range in negative-rail switching. |
| RDS(ON) | 28 mΩ @ VGS = -4.5V - Enables <190 mW conduction loss at 8 A, critical for high-efficiency battery-powered loads. |
| ID (continuous) | -8 A @ TA = +25°C - Supports high-current load switching without external heatsinking on minimal PCB area. |
| Ciss | 806 pF - Low input capacitance reduces gate drive power and speeds up switching transitions. |
| tD(ON) | 13 ns - Fast turn-on delay minimizes overlap losses in synchronous buck or OR-ing configurations. |
| RθJA | 114 °C/W (FR-4, min pad) - Defines junction temperature rise per watt dissipated; used to verify thermal margin at target load. |
| VGS(TH) | -0.5 to -1.5 V - Ensures full enhancement with 3.3 V or 5 V logic control; avoids partial turn-on and shoot-through risk. |
Pinout & Package
U-DFN1616-6 (Type K) package with 0.5 mm pitch, 1.6 × 1.6 mm footprint, and exposed drain pad for thermal and electrical connection. Molded green compound, NiPdAu-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; accepts logic-level negative voltage to modulate channel conductivity; ESD-protected. |
| 2 (S) | Source | Reference node for gate drive; connected to system ground or higher potential rail in high-side configuration. |
| 3 (D) | Drain | Power output node; tied to exposed pad for low-inductance, low-resistance path to PCB ground plane. |
| 4 (D) | Drain | Second drain connection; electrically identical to Pin 3; enhances thermal transfer and current sharing. |
| 5 (S) | Source | Redundant source terminal; improves current handling and reduces bond wire inductance in high-frequency switching. |
| 6 (G) | Gate | Secondary gate connection; provides parallel gate routing path to reduce gate loop inductance and ringing. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at logic-level drive | 28 mΩ @ VGS = -4.5V enables efficient 8 A switching without level-shifting circuitry. |
| ESD-protected gate | Integrated protection diode withstands ±2 kV HBM, reducing need for external TVS in compact designs. |
| Low Ciss and Qg | 806 pF Ciss and 8.5 nC total gate charge minimize driver power and switching energy loss. |
| Thermally enhanced U-DFN | Exposed drain pad delivers 55 °C/W RθJA with thermal bias, supporting >6 A continuous operation. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets automotive and industrial environmental mandates. |

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 |
|---|---|---|---|
| DMG2305UVT-7 | RDS(ON) = 42 mΩ @ -4.5 V; smaller U-DFN2020-6 package; no integrated gate protection diode. | Limited to lower-current (<5 A) applications; requires external gate clamp for transient-prone environments. | Choose when board space is tighter and gate transients are controlled; avoid in unregulated input rails. |
| Si2301DDS-T1-GE3 | RDS(ON) = 115 mΩ @ -4.5 V; TO-236 package; higher RθJA (200 °C/W); AEC-Q101 qualified. | Better automotive qualification but higher conduction loss; unsuitable for >3 A continuous loads. | Prefer for AEC-Q101–mandated automotive sub-systems where current demand is ≤3 A and thermal budget allows. |
Compared with DMG2305UVT-7 and Si2301DDS-T1-GE3, DMP2037UFCL-7 uniquely balances ultra-low RDS(ON), integrated ESD protection, and thermally optimized U-DFN1616-6-making it optimal for high-current, space-constrained, and transient-exposed load-switching roles.

FAQ
What is the maximum continuous drain current at 70°C ambient?
The DMP2037UFCL-7 supports -6 A continuous drain current at TA = +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the U-DFN1616-6 package on standard FR-4 PCBs without thermal enhancement.
Does this MOSFET require a gate resistor for stability?
A gate resistor (typically 10–100 Ω) is recommended to dampen ringing caused by gate-source inductance and driver impedance mismatch. The device's 81 Ω intrinsic gate resistance and 806 pF Ciss make it susceptible to oscillation without proper gate drive layout and series resistance.
Can DMP2037UFCL-7 be used in high-side switching configurations?
Yes-it is a P-channel MOSFET optimized for high-side switching, where source connects to the positive rail and drain feeds the load. Its -20 V VDSS and -1.5 V max VGS(TH) ensure reliable turn-on with common 3.3 V or 5 V logic referenced to the source node.
Is the exposed drain pad electrically connected to the drain terminals?
Yes-the exposed pad (pins 3 and 4) is internally bonded to the drain metallization and must be soldered to a PCB copper pour to achieve specified RθJA and current ratings. Electrical connection is mandatory for both thermal and current-carrying performance.
