Overview
The BC847C/AU,215 is an NPN general-purpose bipolar junction transistor manufactured by Nexperia (formerly Philips Semiconductors). It is housed in a SOT-23 surface-mount plastic package. The device supports a maximum collector current of 100 mA and a collector-emitter voltage of 45 V. It features a high DC current gain (hFE) with a minimum value of 420 at 2 mA and 5 V. The component operates within a temperature range of -65 °C to +150 °C and has a power dissipation rating of 250 mW.
Feature Summary
- NPN polarity configuration for general-purpose switching and amplification
- High DC current gain ensuring effective signal control
- SOT-23 surface-mount packaging for compact circuit integration
Applications
- General purpose switching circuits
- Amplifier stages
- Driver applications
Procurement Notes
Verify the manufacturer designation carefully, as this part number is associated with Nexperia, which acquired the semiconductor division of Philips. Confirm the specific suffix AU,215 corresponds to the required tape-and-reel packaging format. Ensure the datasheet version matches the design requirements for voltage and current ratings. Cross-reference the hFE binning specifications if precise gain thresholds are critical for the application.
Selection Notes
Select this component for designs requiring a small-signal NPN transistor with high gain in a compact footprint. It serves as a complement to the BC857C PNP variant. Consider the 45 V breakdown voltage and 100 mA current limit when designing load paths. The SOT-23 package is suitable for automated assembly processes in consumer and industrial electronics.
Part Context
This component belongs to the BC847 series of NPN general-purpose transistors. It is functionally similar to parts from other manufacturers such as Diodes Incorporated or Fairchild but carries the Nexperia branding. The 'AU,215' suffix indicates specific packaging and ordering details defined by the manufacturer. It is widely used in low-power analog and digital logic interfaces.
Replacement Considerations
Direct substitutes include BC847C from Diodes Incorporated or Fairchild Semiconductor. Other compatible options are BC847C from Transys Electronics or Siemens. Verify pinout compatibility and electrical parameter tolerances before substitution.
