Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'D' corresponds to the required hFE rank of 250-500 during component selection. Confirm that the AP ammo packing format aligns with your assembly line handling requirements. Ensure authorized sourcing channels are used to guarantee genuine parts and full traceability as per manufacturer guidelines.

Single Bipolar Transistors Selection Notes

Select this model when a PNP transistor with a minimum hFE of 250 is required for low-frequency amplification. The TO-92 package suits through-hole mounting needs. Verify that the -55 V voltage ratings and 300 mW power dissipation meet the circuit's thermal and electrical constraints before finalizing the design.

Single Bipolar Transistors Part Context

This component belongs to the 2SA844 series of PNP transistors manufactured by Micro Commercial Components. The series offers various hFE ranks, with the 'D' variant specifically providing a gain range of 250 to 500. These devices are housed in standard TO-92 packages and are intended for general-purpose low-frequency amplification tasks.

Single Bipolar Transistors Replacement Considerations

Consult official datasheets for cross-referencing with other PNP transistors having similar -55 V ratings and TO-92 packaging. Verify pinout compatibility and electrical parameter overlaps before substituting.
