Bipolar RF Transistors Procurement Notes

Verify the manufacturer source carefully, as the 2N5179 designation appears in databases attributed to Micro Electronics rather than Microsemi Corporation. Confirm the specific datasheet version and pinout compatibility before integration. Ensure the TO-72 package dimensions match the target PCB footprint requirements.

Bipolar RF Transistors Selection Notes

Select this component for UHF frequency applications requiring a robust metal-can package. The 12 V rating and 0.05 A current limit define its operational boundaries. Consider the TO-72 form factor for through-hole mounting where high temperature tolerance is required.

Bipolar RF Transistors Part Context

The 2N5179 belongs to the class of silicon NPN RF transistors intended for very high and ultra-high frequency bands. It serves as a discrete semiconductor solution for analog RF signal handling, distinct from integrated RF ICs or microcontrollers found in other product lines.

Bipolar RF Transistors Replacement Considerations

Cross-reference with other TO-72 packaged NPN RF transistors offering similar 12 V ratings and UHF performance specifications. Verify that substitute components maintain compatible pin configurations and thermal resistance values.
