BC846A/SNVL

Overview

The BC846A/SNVL is a single NPN silicon bipolar junction transistor manufactured by Nexperia. It utilizes the SOT-23 (TO-236AB) surface-mount package. Key electrical ratings include a maximum collector-emitter voltage of 65 V, a collector-base voltage of 80 V, and an emitter-base voltage of 6 V. The device supports a maximum DC collector current of 100 mA with a power dissipation of 250 mW. It features a gain-bandwidth product of 100 MHz and operates within a temperature range of -65 °C to +150 °C.

Feature Summary

• Single NPN general-purpose switching and amplification capability
• Internally isolated structure in a compact SMD plastic package
• High thermal stability suitable for demanding environments

Applications

• General-purpose switching circuits
• Signal amplification stages
• Low-voltage logic interfacing

Procurement Notes

Verify the specific suffix SNVL against official Nexperia documentation to confirm tape-and-reel specifications and manufacturing lot codes. Ensure the component matches the standard BC846A electrical parameters defined in the datasheet. Confirm RoHS compliance status through the manufacturer's declaration. Validate that the ordering code corresponds to the correct packaging quantity and handling requirements for your assembly process.

Selection Notes

Select this component for designs requiring a standard NPN transistor with 65 V breakdown voltage in a small footprint. It serves as a direct replacement for legacy BC846A parts in existing schematics. Consider the 100 mA current limit and 250 mW power dissipation when designing load paths. The SOT-23 package facilitates automated pick-and-place assembly for high-volume production runs.

Part Context

This part belongs to the Nexperia BC846 series of small-signal NPN transistors. The series includes variants such as BC846B and BC846C, which differ primarily in DC current gain (hFE) bins. The BC846A variant typically offers a lower minimum hFE compared to other binning options. The SNVL suffix indicates specific packaging or traceability attributes defined by the manufacturer.

Replacement Considerations

Direct pin-compatible substitutes include BC846B, BC846C, and BC847A, provided their gain characteristics meet circuit requirements. Verify that alternative packages match the SOT-23 form factor. Ensure voltage and current ratings of replacements exceed or equal the original design margins.
