Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'P' against the manufacturer's latest Product Standards before purchasing. Confirm the component lifecycle stage, as it may be classified under maintenance or discontinued types. Ensure that the final design specifications align with the most recent datasheet versions available from Panasonic Industry to account for potential specification changes.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a -180 V collector-emitter voltage rating is required. It is appropriate for designs needing up to -1.5 A continuous collector current and 20 W power dissipation capability. Consider the TO-220D-A1 package dimensions for thermal management and PCB layout requirements. Verify that the hFE rank (Q or P) meets the circuit's gain requirements.

Single Bipolar Transistors Part Context

This component belongs to the Panasonic silicon PNP epitaxial planar transistor family. It is specifically engineered for power amplification tasks within television vertical deflection circuits. The product complies with the RoHS Directive (EU 2002/95/EC). It is intended for standard applications in general electronic equipment rather than specialized safety-critical systems.

Single Bipolar Transistors Replacement Considerations

Consult the official Panasonic replacement list for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' transistors without verifying pinout, voltage ratings, and thermal characteristics against the original specifications.
