Overview
The DMP2225L is a P-channel enhancement mode MOSFET designed for high-efficiency power management. It features a -20V drain-source voltage rating and low on-state resistance of 110mΩ at VGS = -4.5V, or 225mΩ at VGS = -2.5V. The device supports a continuous drain current of -2.6A at +25°C and handles pulsed currents up to 8A. Packaged in an SOT-23 case, it offers fast switching speed, low input capacitance, and low leakage. It is qualified to AEC-Q101 standards and is fully RoHS compliant.
Feature Summary
- Low on-state resistance for improved efficiency
- Fast switching speed with low input capacitance
- Qualified to AEC-Q101 automotive reliability standards
- Totally lead-free and fully RoHS compliant
Applications
- General purpose interfacing switch
- Power management functions
Procurement Notes
Verify the specific ordering suffix when purchasing. The standard version is designated as DMP2225L-7, while the automotive-grade variant is marked DMP2225LQ-7. Both utilize the same electrical specifications but differ in qualification status. Confirm package type and tape & reel quantities match design requirements before finalizing orders.
Selection Notes
Select this component for applications requiring a compact P-channel solution with a -20V rating. Ensure gate drive voltages align with the specified thresholds for optimal RDS(ON) performance. Consider thermal dissipation limits in enclosed designs due to the small SOT-23 footprint. Verify compatibility with existing PCB pad layouts for the SOT-23 package.
Part Context
This part belongs to Diodes Incorporated's P-channel MOSFET family. It serves as a legacy component, explicitly marked as not recommended for new designs. Engineers are advised to transition to newer alternatives like the DMP2120Ue3 for future projects to ensure long-term supply availability and updated manufacturing processes.
Replacement Considerations
The datasheet explicitly recommends using the DMP2120Ue3 as a replacement. This newer device offers similar functionality but is suitable for new designs. Verify pinout compatibility and electrical parameters against the DMP2120Ue3 datasheet before implementing any substitution.
