Overview
The DMP4050SSDQ-13 is a dual P-channel enhancement mode MOSFET from Diodes Incorporated, housed in an SO-8 package. It features a -40V drain-source breakdown voltage and a continuous drain current of -5.2A at +25°C. The device achieves a maximum on-resistance of 50mΩ at VGS = -10V and 79mΩ at VGS = -4.5V. It operates within a temperature range of -55°C to +150°C and includes AEC-Q101 qualification for automotive reliability.
Feature Summary
- Dual P-channel configuration integrated into a single compact SO-8 package
- Qualified to AEC-Q101 standards for high reliability applications
- Designed to minimize on-state resistance while maintaining superior switching performance
- Totally lead-free and fully RoHS compliant with halogen and antimony free construction
Applications
- Motor Control
- Backlighting
- DC-DC Converters
- Power Management Functions
Procurement Notes
Verify the 'Q' suffix confirms AEC-Q101 automotive qualification status against the manufacturer's official documentation. Ensure the SO-8 package dimensions match the specific layout requirements of the target PCB design. Confirm that the operating junction temperature limits align with the thermal management strategy of the final assembly.
Selection Notes
Select this component when a dual P-channel solution is required for space-constrained designs. Evaluate the RDS(on) specifications at the intended gate drive voltage to ensure efficiency targets are met. Consider the thermal resistance values if the application involves sustained high-current loads or elevated ambient temperatures.
Part Context
This part belongs to the DMP40 series of dual P-channel MOSFETs manufactured by Diodes Incorporated. The standard version, DMP4050SSD-13, shares identical electrical characteristics but lacks the specific automotive qualification associated with the Q-suffix variant. Both parts utilize the same SO-8 mechanical footprint.
Replacement Considerations
The DMP4050SSD-13 serves as the non-automotive equivalent with matching electrical parameters. Verify pinout compatibility and thermal characteristics before substituting.
