BC846B RFG

Overview

The BC846B RFG is a single NPN bipolar junction transistor manufactured by Taiwan Semiconductor Corporation. It features a maximum collector-emitter voltage of 65 V and a continuous collector current of 100 mA. The device operates within a temperature range of -55°C to +150°C TJ. Key electrical parameters include a DC current gain (hFE) minimum of 200 at 2 mA and 5 V, a transition frequency of 100 MHz, and a power dissipation rating of 200 mW. It is housed in an SOT-23 surface-mount package.

Feature Summary

• Single NPN configuration designed for general-purpose amplification and switching applications
• Automotive-grade qualification compliant with AEC-Q101 standards
• Low saturation voltage characteristics for efficient signal processing
• RoHS 3 compliant construction suitable for environmentally conscious manufacturing

Applications

• General-purpose amplification circuits
• Switching applications in consumer electronics
• Signal processing stages requiring low noise
• Automotive electronic control modules

Procurement Notes

Verify the specific suffix RFG against official Taiwan Semiconductor documentation to confirm packaging type and automotive grade status. Ensure compatibility with SOT-23 footprint requirements during procurement planning. Cross-reference datasheet revisions to confirm compliance with RoHS 3 directives before finalizing supply chain agreements.

Selection Notes

Select this component when a single NPN transistor with 65 V breakdown voltage and 100 mA current capacity is required. Consider the SOT-23 package for space-constrained designs. Verify that the 200 mW power dissipation limit meets thermal management requirements for the intended application environment.

Part Context

This part belongs to the BC846/7/8 series of small-signal NPN transistors. These devices are widely used in portable electronics and communication equipment due to their compact size and reliable performance. The BC846 variant specifically offers higher voltage ratings compared to lower-voltage counterparts in the same family.

Replacement Considerations

BC846B from other manufacturers such as Diotec or Nexperia may serve as functional substitutes if pinout and electrical specifications align. Verify package compatibility and thermal characteristics before substitution.
