Overview
The BC847CW RFG is a single NPN bipolar junction transistor manufactured by Taiwan Semiconductor Corporation. It features a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA. The device operates with a transition frequency of 100 MHz and a maximum power dissipation of 200 mW. DC current gain (hFE) is specified at a minimum of 420 when tested at 2 mA collector current and 5 V collector-emitter voltage. The saturation voltage is limited to 600 mV under conditions of 5 mA base current and 100 mA collector current. Collector cutoff current does not exceed 100 nA. The component is housed in an SOT-323 surface-mount package and supports junction temperatures from -55°C to 150°C.

Procurement Notes
Verify the specific suffix RFG against the manufacturer's official datasheet to confirm the exact binning and testing parameters. Confirm that the AEC-Q101 automotive grade requirement aligns with your system specifications. Ensure the SOT-323 footprint matches your PCB layout constraints. Check for any recent Product Change Notifications regarding molding compounds or pin configurations before finalizing procurement.
Selection Notes
Select this component when high current gain is required for small-signal amplification tasks. The automotive qualification makes it suitable for environments requiring strict reliability standards. Compare the 200 mW power dissipation limit against your thermal design to ensure adequate heat management. Verify that the 45 V breakdown voltage provides sufficient margin for your circuit's operating voltage.
