Overview
The BC857BW/MIF is a PNP general-purpose transistor manufactured by Nexperia. It utilizes the SOT-323 (SC-70) surface-mount plastic package, featuring three pins with dimensions of 2.20 mm in length and 1.35 mm in width. The device supports a maximum DC collector current of 100 mA and a collector-emitter voltage (VCEO) of 45 V. Key electrical parameters include a collector-base voltage (VCBO) of 50 V, an emitter-base voltage (VEBO) of 5 V, and a transition frequency (fT) of 100 MHz. Power dissipation is rated at 200 mW, with a saturation voltage of 250 mV. The component operates within a temperature range of -65°C to +150°C.
Feature Summary
- PNP general-purpose bipolar junction transistor designed for signal amplification and switching applications.
- Ultra-small SOT-323 (SC-70) surface-mount package optimized for space-constrained printed circuit board layouts.
- High DC current gain characteristics suitable for low-power control circuits.
Applications
- General purpose switching
- Signal amplification
- Logic level shifting
Procurement Notes
Verify the specific suffix MIF against official Nexperia documentation to confirm tape-and-reel specifications and marking codes. Ensure compatibility with standard SMT pick-and-place processes for the SOT-323 footprint. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.
Selection Notes
Select this component when a compact PNP transistor is required for low-voltage logic interfaces or small-signal amplification. The SOT-323 package offers a significant reduction in board area compared to larger packages like SOT-23. Consider the 45 V collector-emitter rating and 100 mA current limit to ensure operation remains within safe operating areas for the intended application load.
Part Context
This part belongs to the Nexperia BC857 series of general-purpose transistors. It serves as the PNP complement to the BC847 family. The BC857BW variant specifically denotes the SOT-323 packaging format. This series is widely used in consumer electronics and industrial equipment requiring reliable, low-cost discrete semiconductor solutions for basic analog and digital functions.
Replacement Considerations
Official NPN complements include the BC847BW series. Cross-family replacements such as the BC857B (SOT-23) require footprint adaptation. Verify pinout compatibility and thermal performance when substituting with devices from other manufacturers.
