• Small-signal switching circuits

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source when ordering, as the part number may be distributed by multiple entities. Confirm that the received component matches the TO-226-3 physical dimensions and electrical specifications provided in the official datasheet. Ensure proper handling procedures are followed during installation to maintain device integrity.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring a PNP transistor with moderate voltage ratings and low noise characteristics. The 200 mA current capacity and 50 V breakdown voltage define its operational limits. Consider the through-hole package constraint when designing PCB layouts or selecting alternative surface-mount equivalents if space is limited.

Single Bipolar Transistors Part Context

This component belongs to the family of single bipolar transistors manufactured by onsemi. It serves as a discrete active element within electronic circuits, distinct from integrated solutions. The TO-226AA form factor ensures compatibility with standard axial-leaded mounting techniques used in legacy and industrial designs.

Single Bipolar Transistors Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic replacements must match the PNP configuration, 50 V VCEO, 200 mA IC, and TO-226-3 package constraints to ensure functional equivalence without circuit modification.
