Product details
Overview
DMP2021UFDF-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET optimized for high-efficiency power management, featuring -20V V(BR)DSS, 16mΩ RDS(ON) @ VGS = -4.5V, and -9.0A continuous drain current at TA = +25°C. It serves as a low-side load switch or synchronous rectifier in compact DC-DC converters and battery protection circuits.
For engineers reviewing the DMP2021UFDF-13 datasheet, DMP2021UFDF-13 pinout, DMP2021UFDF-13 application, or DMP2021UFDF-13 equivalent, key selection criteria include gate threshold voltage (-0.35V to -1.0V), thermal resistance (63°C/W with 1-inch copper pad), ESD-protected gate, U-DFN2020-6 footprint compatibility, and JEDEC-qualified reliability for industrial power systems.
Technical Context
This MOSFET employs a trench-gate process to achieve low on-resistance while maintaining fast switching performance, with 34nC total gate charge at VGS = -4.5V and 125ns turn-off delay time under standard test conditions. Its body diode exhibits 48ns reverse recovery time and 33nC Qrr, supporting efficient synchronous rectification.
The device operates across -55°C to +150°C junction temperature range and is rated for ±8V gate-source voltage. Thermal design leverages its 18°C/W junction-to-case resistance and 63°C/W junction-to-ambient (with enhanced copper layout), enabling stable operation in space-constrained, thermally demanding applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | -20V - Maximum blocking voltage before avalanche conduction; defines safe operating range in 12V/15V rail switching. |
| RDS(ON) | 16mΩ @ VGS = -4.5V - Enables <150mW conduction loss at 9A, critical for thermal budget in portable power stages. |
| ID max | -9.0A @ TA = +25°C - Continuous current rating with standard PCB layout; derates to -7.2A at +70°C ambient. |
| Qg | 34nC @ VGS = -4.5V - Determines gate drive energy and switching speed; supports >1MHz operation with low driver loss. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305U-7 | RDS(ON) = 48mΩ @ VGS = -4.5V; higher on-resistance; same U-DFN2020-6 package. | Higher conduction loss limits use to ≤3A loads; less suitable for high-current battery switches. | Select when cost sensitivity outweighs efficiency needs and thermal margin permits higher RDS(ON). |
| SI2301BDS-T1-GE3 | RDS(ON) = 115mΩ @ VGS = -4.5V; larger die size but lower gate charge (12nC); SOT-23 package. | Lower Qg eases gate drive but higher RDS(ON) increases heat generation; incompatible footprint. | Choose for space-tolerant designs where gate drive simplicity and legacy SOT-23 layout reuse are priorities. |
Compared with DMG2305U-7 and SI2301BDS-T1-GE3, DMP2021UFDF-13 delivers the lowest RDS(ON) in the U-DFN2020-6 form factor, enabling higher current density and better thermal performance in thermally constrained layouts-critical for next-gen portable and IoT power stages.

FAQ
What is the maximum continuous drain current for DMP2021UFDF-13 at +70°C ambient?
The maximum continuous drain current is -7.2A at TA = +70°C with standard FR-4 PCB layout (2oz copper, minimum pad). With enhanced thermal layout (1-inch square copper pad), it rises to -8.9A under the same ambient condition, per datasheet Note 6.
Does DMP2021UFDF-13 require external gate resistors for typical 1MHz switching?
No external gate resistor is required for basic turn-on/turn-off control at 1MHz, given its 16Ω typical gate resistance and 34nC gate charge. However, a 2–5Ω series resistor is recommended to dampen ringing caused by PCB trace inductance and prevent gate oscillation in high-noise environments.
Is the thermal pad on the U-DFN2020-6 package electrically connected to any terminal?
Yes-the exposed thermal pad is internally connected to the Source (S) terminals (Pins 1, 4, and 6). It must be soldered to a PCB copper pour tied to the system ground or source net to ensure both thermal performance and electrical integrity.
Can DMP2021UFDF-13 be used in automotive applications?
The DMP2021UFDF-13 is not AEC-Q101 qualified. For automotive use, Diodes offers the pin-compatible DMP2021UFDFQ-13 (Q-suffix), which is AEC-Q101 qualified, PPAP-capable, and manufactured in IATF 16949-certified facilities-listed in their automotive product catalog.
