Procurement Notes
Verify availability status carefully as the component family has been transitioned to End of Life status by the manufacturer. Current supply is limited to existing stock only with no new production planned. Confirm specific ordering suffixes such as PBFREE or TIN/LEAD directly with Central Semiconductor Corp or authorized distributors before placing orders to ensure compliance with plating requirements.
Selection Notes
Select this component for designs requiring a compact PNP RF transistor with a 20 V breakdown voltage. Ensure the application operates within the 225 mW power dissipation limit on appropriate FR-4 substrates. Verify that the 600 MHz transition frequency meets the target circuit bandwidth requirements. Consider the SOT-23 thermal resistance when designing heat management strategies.
