Procurement Notes

Verify component authenticity through authorized CEL distributors or certified suppliers. Confirm the obsolete status and lead times prior to procurement planning. Ensure storage conditions comply with moisture sensitivity levels to maintain reliability during soldering processes.

Selection Notes

Select this component for designs requiring PNP topology at frequencies near 8.5 GHz. Evaluate thermal management capabilities given the 200mW power limit and 150°C junction temperature. Compare noise figures against alternative devices if signal integrity is critical in the 1GHz range.

Part Context

This part belongs to the CEL discrete semiconductor portfolio, specifically within their RF transistor lineup. It serves as a specialized component for microwave frequency applications where low noise and moderate power handling are required in a small form factor.

Replacement Considerations

As the part is marked obsolete, verify functional equivalents with matching SOT-23 packages and similar 8.5 GHz transition frequencies. Cross-reference electrical parameters such as Vceo, Ptot, and noise figure to ensure circuit compatibility.
