Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix required for plating specifications when placing orders. The datasheet indicates that adding 'PBFREE' designates lead-free plated devices, while 'TIN/LEAD' specifies tin/lead plating options. Confirm availability status as the base part number may be subject to discontinuation notices or end-of-life transitions by the manufacturer.

Single Bipolar Transistors Selection Notes

Select this component based on its 15 V collector-emitter voltage rating and 200 mA continuous current capacity. Ensure the application requires the specified 350 MHz transition frequency and low saturation voltage characteristics. Verify thermal management requirements against the 357 °C/W thermal resistance value for the SOT-23 package under expected operating conditions.

Single Bipolar Transistors Part Context

This component belongs to the Central Semiconductor NPN silicon transistor family utilizing the epitaxial planar process. It is functionally similar to other small-signal switching transistors but distinguished by its specific high-frequency performance metrics and surface-mount form factor suitable for compact electronic designs.
