Procurement Notes

Verify the obsolete status of this specific part number before initiating any procurement actions. Confirm that the required resistor ratios align with the final system design requirements. Ensure compliance with environmental directives such as RoHS 3 and halogen-free specifications during sourcing. Validate supplier authenticity through authorized channels to prevent counterfeit components.

Selection Notes

Select this component when a compact PNP solution with integrated base resistance is required. The 1kΩ/1kΩ resistor configuration provides specific drive characteristics suitable for standard logic families. Consider thermal constraints due to the 200mW power dissipation limit in the small SOT-323 package. Evaluate alternative packages if higher current handling or different thermal profiles are necessary.

Part Context

This component belongs to the DDTB series of pre-biased transistors from Diodes Incorporated. The series offers various resistor combinations within the SOT-323 footprint. It serves as a discrete alternative to complex driver stages, consolidating multiple passive and active elements into a single semiconductor package for space-constrained designs.

Replacement Considerations

Public documentation confirms this part number is obsolete. Verify functional equivalents within the same manufacturer's portfolio that maintain identical pinouts and electrical characteristics. Ensure any substitute component meets the same thermal and voltage ratings.
