Product details
Overview
DMP21D0UFD-7 from Diodes Incorporated is a 20V P-channel enhancement-mode MOSFET in a 1.2mm × 1.2mm X1-DFN1212-3 package, featuring 495mΩ RDS(on) at VGS = −4.5V, −1.14A continuous drain current at 25°C, and 3kV ESD protection on gate. It serves as a low-side load switch in portable power rails.
For engineers reviewing the DMP21D0UFD-7 datasheet, DMP21D0UFD-7 pinout, DMP21D0UFD-7 application, or DMP21D0UFD-7 equivalent, key selection criteria include gate threshold voltage (−0.45 to −1.2V), thermal resistance (135°C/W on 15mm × 15mm 2oz Cu), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This MOSFET uses planar trench-gate technology optimized for low RDS(on) while maintaining fast switching speed (tD(on) = 7.1ns, tD(off) = 31.7ns) and robust gate oxide integrity. Its −20V VDSS rating and ±8V VGSS support operation in 3.3V/5V logic-controlled 12V rail systems.
The device integrates an intrinsic body diode with VSD = −1.2V at −300mA and exhibits normalized RDS(on) variation of <1.4× across −55°C to +150°C ambient, enabling stable performance in battery-powered thermal environments.

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 |
|---|---|---|---|
| DMN2011LFG-7 | RDS(on) = 320mΩ @ −4.5V but larger 2mm × 2mm DFN2020 package; higher Qg = 2.3nC | Better conduction efficiency but slower switching and larger board area | Select when lower I2R loss dominates over size and speed constraints |
| SI2301DS-T1-BE3 | RDS(on) = 130mΩ @ −4.5V but only rated to −20V VDSS; no AEC-Q101 qualification | Higher current capability but unsuitable for automotive or transient-prone environments | Select for cost-sensitive consumer electronics where AEC-Q101 is not required |
Compared with DMN2011LFG-7 and SI2301DS-T1-BE3, DMP21D0UFD-7 uniquely balances ultra-small footprint (1.2mm²), AEC-Q101 qualification, and gate-threshold compatibility with 1.8V logic-making it optimal for space-constrained automotive and portable designs requiring guaranteed reliability.

FAQ
What is the maximum continuous drain current for DMP21D0UFD-7 at 85°C ambient?
The maximum continuous drain current is −0.83A at TA = 85°C when mounted on a 15mm × 15mm × 1.6mm FR4 PCB with 2oz copper. This derating reflects thermal resistance of 135°C/W and junction temperature limit of 150°C. At minimum pad layout, the rating drops to −0.82A due to higher RθJA = 256°C/W.
Does DMP21D0UFD-7 require external gate pull-up or pull-down resistors?
No external gate resistor is required for static operation, but a 10–15Ω series gate resistor is recommended to dampen ringing during fast switching. The device's −0.45V minimum VGS(th) ensures turn-on with standard 1.8V/3.3V GPIO; no pull-up is needed since it is P-channel and driven low to conduct.
Is the DMP21D0UFD-7 package compatible with reflow soldering per J-STD-020?
Yes, the X1-DFN1212-3 package has moisture sensitivity level 1 and is qualified for standard Pb-free reflow profiles (peak temperature 260°C). The NiPdAu terminal finish ensures reliable solderability per MIL-STD-202, Method 208, and the UL 94V-0 mold compound withstands multiple reflow cycles without delamination.
How does the body diode forward voltage affect reverse-current protection?
The intrinsic body diode has VSD = −1.2V at −300mA, which limits reverse conduction loss during back-powering events. In load-switch applications, this diode conducts only during turn-off transients or fault conditions; its relatively high VF helps prevent unintended reverse current flow compared to Schottky alternatives, enhancing system-level fault isolation.
