Procurement Notes

Verify the manufacturer designation carefully, as the part is listed under both Microsemi Corporation and Microchip Technology due to corporate acquisition history. Confirm the exact datasheet version and RoHS compliance status with the supplier before procurement. Ensure the ordering suffix matches the required packaging configuration, as availability may vary between distributors.

Selection Notes

Select this component specifically for RF applications requiring an NPN silicon bipolar transistor. Verify that the operating frequency range and power requirements of the target circuit align with the device's specifications. Consider the package type and thermal management needs during the design phase to ensure reliable performance in the intended environment.

Part Context

Microsemi Corporation was acquired by Microchip Technology, leading to the integration of Microsemi's product portfolio into the Microchip brand. Consequently, parts formerly identified solely under Microsemi are now often distributed and documented under Microchip Technology. This transition affects branding on datasheets and ordering information but does not alter the underlying component specifications or functionality.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult official Microchip or Microsemi technical support channels for validated cross-reference data or compatible alternatives suitable for specific RF design constraints.
