BC858B RFG

Overview

The BC858B RFG is a PNP general-purpose transistor manufactured by Taiwan Semiconductor Corporation. It features a collector-emitter voltage of -30V and a maximum collector current of -100mA. The device operates within a junction temperature range of -55°C to +150°C and dissipates up to 200mW of power. It utilizes an SOT-23 surface-mount package with three terminals. The DC current gain (hFE) is specified at a minimum of 220 under test conditions of 2mA base current and 5V collector-emitter voltage.

Feature Summary

PNP bipolar junction transistor designed for general-purpose amplification applications
Surface-mount construction in a compact SOT-23 package for automated assembly
High DC current gain ensuring effective signal control with low input drive
Wide operating temperature range suitable for diverse environmental conditions

Applications

General-purpose amplifier circuits
Switching applications requiring low power consumption
Complementary pairing with NPN transistors such as the BC848 series
Signal processing in consumer electronic devices

Procurement Notes

Verify the specific manufacturer designation, as the model suffix may indicate regional or distributor-specific packaging variations. Confirm RoHS compliance status through official datasheets prior to integration. Ensure the sourcing channel provides authentic components from Taiwan Semiconductor Corporation to guarantee electrical parameter consistency and long-term reliability in final assemblies.

Selection Notes

Select this component when a PNP transistor with 30V breakdown voltage and 100mA continuous current capability is required. The SOT-23 package offers space efficiency for dense PCB layouts. Consider the hFE binning specifications if precise gain matching is necessary for the application. Evaluate thermal management requirements based on the 200mW power dissipation limit in the chosen enclosure environment.

Part Context

This part belongs to the BC858 series of PNP transistors, which are widely used in analog and digital switching circuits. The 'RFG' suffix typically denotes specific tape-and-reel packaging configurations intended for high-volume surface-mount technology production lines. It serves as the complementary counterpart to the BC848B NPN transistor in many standard circuit designs.
