BC848C RFG

Overview

The BC848C RFG is a single NPN bipolar junction transistor manufactured by Taiwan Semiconductor Corporation. It features a maximum collector-emitter voltage of 30 V and a continuous collector current of 100 mA. The device operates with a transition frequency of 300 MHz and a maximum power dissipation of 250 mW. DC current gain (hFE) is specified at a minimum of 200 when tested at 2 mA collector current and 5 V collector-emitter voltage. The saturation voltage is limited to 600 mV at 5 mA base current and 100 mA collector current. Collector cutoff current does not exceed 100 nA. The component is housed in an SOT-23 surface-mount package and supports junction temperatures from -55°C to 150°C.

Feature Summary

• High-speed switching capability enabled by a 300 MHz transition frequency
• Enhanced signal amplification through a minimum DC current gain of 200
• Robust thermal performance supporting operation up to 150°C junction temperature

Applications

• General-purpose signal amplification circuits
• High-frequency switching applications
• Low-power digital logic interfacing

Procurement Notes

Verify the specific suffix RFG against official Taiwan Semiconductor documentation to confirm packaging configuration and manufacturing lot details. Ensure compatibility with RoHS3 standards as indicated in public distributor records. Cross-reference the manufacturer part number with authorized supply channels to validate authenticity and traceability before integration into production schedules.

Selection Notes

Select this component for designs requiring moderate voltage handling and high-speed response within a compact footprint. The 30 V rating suits low-voltage systems, while the 300 MHz frequency supports faster signal processing. Compare the 250 mW power dissipation limit against thermal constraints to ensure reliable operation under expected load conditions without exceeding junction temperature limits.

Part Context

This device belongs to the BC848 series of small-signal NPN transistors designed for general electronic applications. The RFG suffix denotes specific packaging or tape-and-reel configurations provided by Taiwan Semiconductor. It serves as a standard replacement for legacy BJT components in consumer electronics and industrial control modules where space efficiency and switching speed are prioritized over high-power handling capabilities.

Replacement Considerations

Public records indicate BC848B RFG as a potential substitute variant from the same manufacturer.
