Overview
The Diotec Semiconductor BC858C is a general-purpose PNP bipolar junction transistor (BJT) designed for surface-mount applications. It operates within a collector-emitter voltage of -30 V and supports a continuous DC collector current of -100 mA. The device dissipates up to 250 mW of power and features three distinct DC current gain groups, with the 'C' suffix indicating the highest gain range. Manufactured in an SOT-23 package, it complies with RoHS standards and is suitable for signal processing, switching, and amplification tasks.
Feature Summary
- General-purpose PNP transistor optimized for universal application in standard electronic circuits
- Available in three specific DC current gain groups to accommodate varying circuit requirements
- Compliant with RoHS directives, REACH regulations, and conflict mineral sourcing standards
Applications
- Signal processing
- Switching
- Amplification
Procurement Notes
Verify the exact ordering code includes the '-C' suffix to confirm the specific high-gain commercial grade variant. Confirm that the SOT-23 package dimensions align with the target PCB footprint. Ensure the design accounts for the 250 mW power dissipation limit under expected operating conditions. Check for any specific automotive qualification requirements if the end-use environment demands AEC-Q101 compliance.
Selection Notes
Select this component when a PNP transistor with a -30 V collector-emitter rating is required. The BC858C provides the highest current gain group among the available options, making it suitable for applications demanding higher sensitivity or lower base drive currents. Compare against complementary NPN transistors like the BC848C if matched pairs are needed for differential stages.
Part Context
This part belongs to the BC856...BC860 family of SMD general-purpose PNP transistors from Diotec Semiconductor. The series offers various voltage ratings and gain groupings across different packages. The BC858C specifically addresses low-voltage applications requiring high gain, complementing other members like the BC857 and BC859 which offer higher voltage tolerances.
Replacement Considerations
Check for BC858B or BC858A variants if lower gain thresholds are acceptable. Verify compatibility with BC857C or BC859C if higher voltage ratings are not critical but pinout and package must remain identical.
