Overview
The BCY79-VIII PBFREE is a small signal PNP silicon transistor manufactured by Central Semiconductor Corp. It features a maximum collector current of 0.1 A and a collector-emitter breakdown voltage of 45 V. The device operates in a TO-18 metal can package with three terminals. Key electrical specifications include a transition frequency of 100 MHz and a power dissipation rating of 1 W. This component is designed for general-purpose switching applications within the specified thermal and electrical limits.
Feature Summary
- PNP silicon construction for reliable small-signal switching
- Hermetically sealed TO-18 metal can package
- High transition frequency capability for signal processing
- Lead-free compliant manufacturing process
Applications
- General purpose switching circuits
- Small signal amplification stages
- Audio pre-amplifier inputs
- Logic interface buffers
Procurement Notes
Verify the specific manufacturer datasheet for the BCY79-VIII PBFREE to confirm exact electrical tolerances and thermal characteristics. Ensure the procurement specification matches the required lead-free compliance standards. Cross-reference the TO-18 pinout configuration with the target circuit design to prevent installation errors. Confirm that the 0.1 A current rating meets the application load requirements before finalizing orders.
Selection Notes
Select this component when a hermetically sealed PNP transistor is required for high-reliability environments. The TO-18 package offers superior thermal stability compared to plastic equivalents. Consider the 45 V breakdown voltage limit when designing for higher voltage rails. The 100 MHz frequency response makes it suitable for audio and low-frequency RF applications rather than high-speed digital switching.
Part Context
This part belongs to the BCY79 series of PNP switching transistors. Variants such as the standard BCY79-VIII may differ in packaging or compliance status. Central Semiconductor produces this specific lead-free version to meet modern environmental regulations while maintaining the performance characteristics of the legacy BCY79 family.
Replacement Considerations
Direct substitutes include the Philips/NXP BCY79VIII and STMicroelectronics BCY79 variants. Verify pin compatibility and electrical ratings before substitution. Other manufacturers may offer equivalent PNP transistors in TO-18 packages, but thermal and voltage derating must be re-evaluated.
