Overview
The Diotec Semiconductor BC847CW is a single NPN general-purpose transistor housed in an SOT-323 surface-mount package. It features a maximum collector-emitter voltage (VCEO) of 45 V and a continuous DC collector current (IC) of 100 mA. The device offers three distinct DC current gain (hFE) groups: Group A (110–220), Group B (200–450), and Group C (420–800). Key electrical characteristics include a collector-base cutoff current (ICBO) of 15 nA, a transition frequency (fT) of 100 MHz, and a power dissipation (Ptot) of 200 mW. The component operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Provides three selectable DC current gain groups for precise amplification control
- Designed for low-noise signal processing and switching applications
- Compliant with RoHS directives and REACH regulations
Applications
- Signal processing circuits
- Electronic switching functions
- General-purpose amplification stages
Procurement Notes
Verify the specific hFE group (A, B, or C) required for your design, as the datasheet lists ranges for all three. Confirm that the commercial grade suffix (-C) aligns with your environmental requirements. Ensure the SOT-323 footprint matches your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a compact NPN transistor with a 45 V rating is needed. Choose based on the required current gain tolerance; Group C offers the highest gain range. Consider the BC846CW if a higher 65 V rating is necessary, or the BC848CW if a lower 30 V rating suffices. Verify thermal resistance limits under your specific board copper pad conditions.
Part Context
This part belongs to the BC846W through BC849W series of SMD general-purpose NPN transistors manufactured by Diotec Semiconductor. The 'CW' designation indicates the commercial grade variant packaged in the SOT-323 case. Complementary PNP transistors in this family include the BC857W and BC860W series.
Replacement Considerations
BC846CW serves as a higher voltage alternative (65 V). BC848CW provides a lower voltage option (30 V). BC847AW represents the industrial grade equivalent of this component.
