Procurement Notes
Verify the specific ordering suffix (-7 or -13) against your required tape and reel quantity. Confirm that the standard commercial version meets your application requirements, as automotive-compliant variants are available under separate datasheets. Ensure proper handling for ESD-sensitive components during assembly.
Selection Notes
Select this component for applications requiring dual P-channel switching in a compact SOT363 footprint. Evaluate the R_DS(ON) values at your specific gate drive voltages (-4.5 V or -10 V) to ensure acceptable conduction losses. Consider the thermal resistance limits when designing heat dissipation strategies for steady-state operations.
Part Context
This device belongs to Diodes Incorporated's DMP series of dual P-channel enhancement mode MOSFETs. It is designed to minimize on-state resistance while maintaining superior switching performance. The product is totally lead-free, fully RoHS compliant, and halogen and antimony free.
Replacement Considerations
An automotive-compliant part is available under a separate datasheet: DMP31D7LDWQ.
