BC847A RFG

Overview

The BC847A 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 rating of 100 mA. The device operates with a transition frequency of 100 MHz and dissipates up to 200 mW of power. It exhibits a minimum DC current gain of 110 at 2 mA base current and 5 V collector-emitter voltage, with a maximum saturation voltage of 600 mV under specified conditions. The component is housed in an SOT-323 surface-mount package and supports a junction temperature range from -55°C to 150°C.

Feature Summary

• Single NPN configuration designed for general-purpose switching and amplification applications
• Compact SOT-323 surface-mount package optimized for automated assembly processes
• High thermal stability supporting extended operating temperatures up to 150°C

Applications

• General-purpose signal amplification circuits
• Low-power electronic switching applications
• Portable consumer electronics requiring compact form factors

Procurement Notes

Verify the complete part number including the RFG suffix against official manufacturer documentation to ensure correct packaging and specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference datasheet parameters such as hFE binning and saturation voltages with specific design constraints to guarantee circuit performance alignment.

Selection Notes

Select this component when a small-footprint NPN transistor with moderate voltage ratings is required. Ensure the application current remains within the 100 mA limit and power dissipation stays below 200 mW. Verify that the SOT-323 package dimensions fit the printed circuit board layout constraints and that the 100 MHz frequency response meets the signal processing requirements.

Part Context

This component belongs to the BC847 series of dual-polar transistors produced by Taiwan Semiconductor Corporation. It shares the same physical footprint and basic electrical characteristics as other variants within the family, differing primarily in current gain classification and packaging options. The RFG suffix typically denotes specific reel packaging configurations used in high-volume manufacturing environments.

Replacement Considerations

Direct substitutes include BC847AW RFG from the same manufacturer. Other compatible alternatives may include BC847AW from Diotec Semiconductor or BC847A_R2_10001 from Panjit International, provided pinout compatibility and electrical limits are verified.
