Overview
The BC858C RFG is a small-signal PNP bipolar junction transistor manufactured by Taiwan Semiconductor Corporation. It features a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 30 V. The device operates within a junction temperature range of -55°C to +150°C and has a maximum power dissipation of 250 mW. Packaged in the SOT-23 (TO-236) surface-mount format, it offers a transition frequency of 100 MHz and a minimum DC current gain (hFE) of 420 at specified test conditions.
Feature Summary
- Utilizes a compact SOT-23 surface-mount package for efficient PCB space utilization.
- Provides high DC current gain suitable for amplification applications.
- Engineered for reliable operation across an extended industrial temperature range.
Applications
- General-purpose signal amplification circuits
- Switching applications in low-power digital logic interfaces
- Audio pre-amplifier stages
Procurement Notes
Verify the specific suffix 'RFG' against the official Taiwan Semiconductor datasheet to confirm packaging details and tape-and-reel specifications. Ensure the component matches the required hFE binning and thermal characteristics for your design. Cross-reference with authorized distributors to validate authenticity and traceability documentation before finalizing procurement.
Selection Notes
Select this component when a PNP transistor with 30V rating and 100mA continuous current capability is required in an SOT-23 package. Consider the 100MHz transition frequency for medium-speed switching or amplification tasks. Verify that the 250mW power dissipation limit aligns with your thermal management strategy and ambient operating conditions.
Part Context
The BC858C belongs to the widely used BC858 series of general-purpose PNP transistors. This series is standardized across multiple manufacturers for compatibility in consumer electronics and industrial control systems. The 'C' suffix typically denotes a specific DC current gain range, ensuring consistent performance for mass-produced designs requiring predictable hFE values.
Replacement Considerations
Compatible substitutes include BC858C from Diotec Semiconductor, Nexperia, and Micro Commercial Components. Ensure the replacement part maintains the same SOT-23 footprint and meets the 30V/100mA electrical ratings. Verify that the alternative manufacturer's hFE grading matches the original design requirements.
