Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package dimensions and reel specifications. Ensure compliance with RoHS directives and halogen-free requirements before integration into final assemblies. Confirm availability through authorized distribution channels.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required in a compact SOT563 footprint. Verify that the 2.2 kΩ base resistor and 47 kΩ emitter resistor align with the target circuit's drive requirements. Check that the -50 V collector-emitter breakdown voltage accommodates the maximum operating voltage.

Part Context

This part belongs to the DDA series of PNP pre-biased transistors from Diodes Incorporated. It is designed as a complementary counterpart to NPN types within the same family. The H suffix indicates the specific SOT563 package variant used for surface mount assembly.

Replacement Considerations

Complementary NPN types are available within the same product family. Verify pinout compatibility and electrical characteristics before substituting with other manufacturers' equivalents.
