The BC857BV,115 is a PNP general-purpose double transistor manufactured by Nexperia. It utilizes an ultra-small SOT666 flat lead plastic package with dimensions of 1.6 mm x 1.2 mm x 0.55 mm. The device features excellent coplanarity due to straight leads and offers low collector capacitance for improved performance. It serves as a replacement for two SC-75 or SC-89 packaged BISS transistors, reducing component count and board space. The total power dissipation is rated at 300 mW.
Verify the specific suffix against official Nexperia documentation to confirm pinout compatibility and electrical tolerances. Confirm availability status through authorized distributors, as supply chain conditions may vary. Ensure the selected packaging format matches the intended automated assembly requirements.
Select this component when minimizing footprint is critical compared to standard SOT-23 packages. The SOT666 form factor allows integration where space constraints prevent the use of larger dual-transistor solutions. Evaluate thermal management needs relative to the 300 mW total power dissipation rating in the final enclosure.
This part belongs to the BC847/BC857 series of general-purpose small-signal transistors. The BV suffix specifically denotes the PNP variant housed in the compact SOT666 package. It complements the NPN BC847BV within the same family, offering matched characteristics for differential pairs or push-pull configurations.
Public confirmed substitute part numbers: BC857BV (generic). Verify pinout alignment before substitution.
