BC847B/SNVL

Overview

The BC847B/SNVL is a single NPN general-purpose bipolar junction transistor manufactured by Nexperia. It utilizes the SNVL surface-mount package, designed for automated assembly in compact electronic circuits. The device features a maximum collector-emitter voltage of 45 V and a continuous collector current rating of 100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 200 at a collector current of 2 mA. The component operates within a temperature range from -65 °C to +150 °C and complies with RoHS standards.

Feature Summary

• Single NPN configuration optimized for general-purpose switching and amplification tasks
• High DC current gain ensures effective signal control with minimal base drive requirements
• Compact surface-mount footprint facilitates high-density PCB layout and automated manufacturing

Applications

• General-purpose signal switching in consumer electronics
• Amplifier stages in portable audio and communication devices
• Logic level translation and buffer circuits in industrial control systems

Procurement Notes

Verify the specific SNVL package designation against official Nexperia documentation to confirm pinout compatibility and thermal characteristics. Ensure that the selected supplier provides traceable components meeting RoHS directives. Confirm availability through authorized distribution channels to mitigate counterfeit risks. Validate that the ordering suffix aligns with required reel or cut-tape specifications for production integration.

Selection Notes

Select this component when a single NPN transistor with moderate voltage ratings and high gain is required in a small form factor. The SNVL package offers advantages in space-constrained designs compared to larger through-hole alternatives. Consider thermal dissipation limits during high-current operation. Verify that the 45 V breakdown voltage meets the circuit's peak operating conditions without derating issues.

Part Context

This part belongs to the BC847 series of general-purpose NPN transistors, widely used in low-power applications. The series includes variants with different gain ranges and complementary PNP types. The SNVL package represents a specific surface-mount option within Nexperia's portfolio, distinct from standard SOT-23 packages. This series is recognized for reliability in mass-produced consumer and industrial equipment.

Replacement Considerations

Direct substitutes include other Nexperia BC847 variants in compatible packages, such as BC847B in SOT-23, if pinout alignment allows. Cross-manufacturer equivalents like ON Semiconductor or Infineon parts in identical packages may be considered after verifying electrical parameter matching.
