• Low-power signal amplification circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lifecycle notices such as obsolescence or last-time buy notifications before finalizing procurement plans.

Selection Notes

Select this component when a PNP configuration with 0.47 kΩ base resistor is required in a compact SOT-523 footprint. Ensure the application voltage does not exceed the -40 V collector-emitter rating and that thermal management accommodates the 150 mW dissipation limit.

Part Context

This part belongs to the DDTA series of pre-biased transistors from Diodes Incorporated. It is specifically designed for applications needing simplified bias networks. The 'TE' suffix indicates the specific resistor ratio configuration, distinguishing it from other variants like DDTA122TE.

Replacement Considerations

Complementary NPN types are available within the same family. Verify pinout compatibility and electrical ratings against existing designs when considering alternative pre-biased transistor models.
