Overview
The BC857BW/SNX is a PNP general-purpose transistor manufactured by Nexperia. It operates with a collector-emitter voltage of 45 V and a maximum DC collector current of 100 mA. The device features a DC current gain (hFE) range of 220 to 475, ensuring high amplification capability for small signal applications. Power dissipation is rated at 200 mW within an SOT-323 (SC-70) surface-mount package. Key electrical limits include a collector-base voltage of 50 V, an emitter-base voltage of 5 V, and a transition frequency of 100 MHz. The component supports a storage temperature range from -65°C to +150°C.
Feature Summary
- PNP general-purpose transistor in a very small SOT-323 plastic package
- High DC current gain suitable for amplification tasks
- Lead-free packaging compliant with RoHS standards
Applications
- General-purpose switching
- Small signal amplification
- Low and medium frequency AC applications
Procurement Notes
Verify the specific suffix SNX against official Nexperia documentation to confirm tape-and-reel specifications and marking codes. Ensure compatibility with standard SC-70 footprints during PCB layout. Confirm that the hFE binning matches circuit requirements for consistent gain performance across production batches.
Selection Notes
Select this component when board space is limited due to its compact SOT-323 form factor. It serves as a direct complement to NPN devices like the BC847BW. Consider the 45 V breakdown voltage and 100 mA current limit to ensure operation remains within safe operating areas for low-power signal processing circuits.
Part Context
This part belongs to the BC857W series of PNP transistors designed for general-purpose use. It is functionally paired with the BC847W NPN counterpart. The series utilizes a standardized SC-70 footprint to facilitate automated assembly and reduce overall board area consumption in portable electronic designs.
Replacement Considerations
Officially documented complements include the BC847BW. Verify pinout compatibility before substituting with other SC-70 PNP transistors such as the BC857AW or BC857C variants.
