Overview
The BC850C-AU_R1_000A1 is an NPN general-purpose bipolar junction transistor manufactured by Panjit International Inc. It features a collector current of 100 mA and a collector-emitter voltage rating of 45 V. The device utilizes a silicon planar epitaxial structure housed in a SOT-23 surface-mount package. It meets AEC-Q101 automotive qualification standards, ensuring reliability for demanding environments. The component operates within a temperature range of -55°C to +150°C and complies with RoHS directives.
Feature Summary
- NPN epitaxial silicon planar design for general-purpose amplification
- Automotive grade qualification compliant with AEC-Q101 standards
- Surface-mount SOT-23 packaging for compact circuit integration
Applications
- General purpose amplifier circuits
- Switching applications in consumer electronics
- Signal processing stages in industrial control systems
Procurement Notes
Verify the specific suffix AU_R1_000A1 against official Panjit documentation to confirm reel specifications and tape-and-reel dimensions. Ensure compatibility with standard SOT-23 footprint designs during procurement planning. Cross-reference the AEC-Q101 certification status directly with the manufacturer's latest quality reports to validate automotive suitability requirements.
Selection Notes
Select this component when a small-signal NPN transistor with 45V breakdown and 100mA continuous current capability is required. The SOT-23 form factor suits space-constrained PCB layouts. Consider the AEC-Q101 qualification if the application demands automotive-grade reliability and thermal stability up to 150°C junction temperature.
Part Context
This part belongs to the BC850 series of NPN general-purpose transistors from Panjit. The series offers variants with different DC current gain (hFE) grades, such as B, C, and D, to accommodate various amplification requirements. The BC850C specifically targets applications needing standardized gain characteristics within the broader family of low-power switching and amplification devices.
Replacement Considerations
Compatible substitutes include other NPN transistors in the SOT-23 package with similar 45V VCEO and 100mA IC ratings, such as the BC847 or BC857 series, provided their hFE grades match the circuit design constraints.
