Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin, as this component is produced by both Fairchild Semiconductor and onsemi. Confirm the package type is TO-243AA (SOT-89) and that the device is an NPN bipolar junction transistor. Ensure the transition frequency specification aligns with your design requirements of 150MHz before integration.

Single Bipolar Transistors Selection Notes

Select this component when a small-form-factor NPN transistor is required for surface-mount assembly. The TO-243AA package supports high-density hybrid IC integration. Consider the 150MHz transition frequency for medium-speed RF or switching applications where space constraints are critical.

Single Bipolar Transistors Part Context

This transistor belongs to the family of general-purpose bipolar junction transistors (BJTs). It is commonly used in consumer electronics and industrial control systems where reliable NPN switching is needed. The SOT-89 package variant allows for automated placement in modern manufacturing processes.

Single Bipolar Transistors Replacement Considerations

Check for equivalents from onsemi or other manufacturers offering NPN transistors in the TO-243AA package with similar 150MHz frequency characteristics. Verify pinout compatibility and electrical ratings before substitution.
