Product details
Overview
DMP1022UWS-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in a V-DFN3020-8 package, rated for -12V VDSS, 18mΩ RDS(ON) at VGS = -4.5V, and -7.2A continuous drain current at TA = +25°C. It integrates ESD-protected gate structure and low input capacitance (2847pF), enabling high-efficiency load switching in compact DC-DC converters.
For engineers reviewing the DMP1022UWS-13 datasheet, DMP1022UWS-13 pinout, DMP1022UWS-13 application, or DMP1022UWS-13 equivalent, key selection criteria include its -1.0V to -1.0V gate threshold range, 9mJ avalanche energy rating, thermal resistance of 90°C/W (with enhanced layout), fast 20ns turn-on delay, and compatibility with 1.8V–4.5V logic-level gate drive in space-constrained power rails.
Technical Context
This MOSFET operates as a high-side load switch or synchronous rectifier in buck converters and battery protection circuits. Its P-channel topology eliminates need for high-side gate driver circuitry, while low RDS(ON) at -2.5V VGS (22mΩ) supports direct interface with 2.5V/3.3V microcontroller GPIOs.
The device features integrated gate protection diode and body diode with -0.8V forward voltage at -8A, enabling bidirectional current handling in reverse-polarity protection and OR-ing applications. Thermal performance is validated under JEDEC-standard FR-4 board conditions with 2oz copper and thermal bias.

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG1022UVT-7 | Same RDS(ON) (18mΩ@-4.5V) but in smaller V-DFN2020-6 package; no exposed drain pad | Limited thermal dissipation (RθJA = 135°C/W); unsuitable for >3A continuous loads | Select when board area is critical and power dissipation remains below 0.5W |
| Si2301DDS-T1-GE3 | Higher RDS(ON) (100mΩ@-4.5V); lower ID (-2.7A); no avalanche rating | Not rated for inductive switching; requires external TVS for solenoid drivers | Select only for low-power logic-level switching where cost outweighs thermal performance |
Compared with DMG1022UVT-7 and Si2301DDS-T1-GE3, DMP1022UWS-13 delivers superior thermal management via its exposed drain pad and 9mJ avalanche capability-critical for industrial load switching where reliability under transient stress is non-negotiable.

FAQ
What is the maximum safe operating temperature for DMP1022UWS-13?
The junction temperature must not exceed +150°C under any condition. With RθJA = 90°C/W on an enhanced FR-4 board, the device sustains 1.4W continuous power dissipation at +25°C ambient. Derating is required above +25°C per the 1.56°C/W slope shown in Figure 13's transient thermal curve.
Can DMP1022UWS-13 be used in synchronous rectification?
Yes-it is qualified for synchronous rectifier use in buck converters due to its low RDS(ON) (18mΩ), fast 93ns fall time, and body diode recovery charge (QRR = 13nC). Its -0.8V VSD at -8A reduces conduction loss versus Schottky alternatives in 5V–12V output rails.
Does this MOSFET require external gate resistors for stability?
No external gate resistor is required for basic switching, as its 9Ω gate resistance and 2847pF Ciss yield a natural RC time constant compatible with standard 3.3V/5V drivers. However, a 10Ω series resistor is recommended when driving from high-impedance sources to damp ringing observed in Figure 11's gate charge curve.
How does the ESD protection affect layout requirements?
The integrated ESD diode connects gate to source, so PCB layout must avoid routing high-dv/dt signals near the gate trace. Keep gate traces short (<5mm), avoid vias, and place a 100nF ceramic capacitor between source and ground within 2mm of the package to suppress coupling-induced gate transients.
