Overview
The Nexperia BC857BW/SNF is a PNP general-purpose transistor housed in the SOT-323 (SC-70) surface-mount plastic package. It features a maximum collector current of 100 mA and a collector-emitter voltage rating of 45 V. The device offers a DC current gain (hFE) range of 220 to 475, with a transition frequency of 100 MHz. Power dissipation is rated at 200 mW, and the collector-emitter saturation voltage is 250 mV. Operating temperatures extend from -65 °C to +150 °C.
Feature Summary
- PNP bipolar junction transistor configured for general-purpose switching and amplification tasks.
- Ultra-small leadless SMD plastic package designed to minimize printed circuit board space requirements.
- High DC current gain characteristics suitable for low-level signal processing applications.
Applications
- General-purpose small signal DC applications
- Low and medium frequency AC applications
- Mobile electronic devices
Procurement Notes
Verify the specific suffix SNF against official Nexperia documentation to confirm reel packaging specifications and marking codes. Ensure compatibility with standard SMT assembly processes for the SOT-323 footprint. Confirm moisture sensitivity level ratings prior to storage and handling procedures.
Selection Notes
Select this component when board space constraints require an ultra-small SOT-323 package instead of larger alternatives like SOT-23. Choose based on the required 45 V collector-emitter voltage and 100 mA current limits. Verify that the hFE binning meets the specific gain requirements of the target circuit design.
Part Context
This part belongs to the Nexperia BC857W series of PNP transistors. It serves as the complement to the NPN BC847W series. The family includes variants such as BC856W, BC857AW, and BC858W, all sharing similar electrical characteristics but differing in gain ranges or complementary configurations within the same compact package technology.
Replacement Considerations
Official substitutes include BC857W,115 and BC857W,135. These parts share identical electrical specifications and the SOT-323 package. Verify pinout orientation and marking codes to ensure direct interchangeability in existing designs.
