Procurement Notes
Verify the specific ordering suffix '-13' corresponds to the Tape & Reel packing quantity of 2500 units. Confirm that the component meets RoHS, Halogen-free, and Antimony-free requirements as defined by Diodes Incorporated. Ensure the application environment supports the specified thermal characteristics and operating temperature ranges.
Selection Notes
Select this component for designs requiring high-current P-channel switching in automotive environments. Consider the low on-resistance for efficiency and the robust thermal rating for high ambient temperatures. Verify gate drive compatibility with the specified threshold voltage and ensure PCB layout accommodates the TO252 package dimensions.
Part Context
This part belongs to the DMPH series of P-channel MOSFETs from Diodes Incorporated. It is manufactured in IATF 16949 certified facilities, ensuring quality control suitable for automotive supply chains. The device utilizes a molded plastic green molding compound with a matte tin finish annealed over a copper leadframe.
Replacement Considerations
Consult official documentation for verified substitutes. Cross-reference electrical parameters such as BVDSS, RDS(ON), and package type when evaluating alternatives.
