BC857BW/ZLX

Overview

The Nexperia BC857BW/ZLX is a PNP general-purpose transistor housed in the SOT323 (SC-70) surface-mount package. It features a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA. The device offers a DC current gain (hFE) range of 220 to 475 at specified test conditions, with a transition frequency of 100 MHz. Power dissipation is rated at 200 mW, and it supports an operating temperature up to +150°C.

Feature Summary

PNP general-purpose transistor configuration
Ultra-small SOT323 surface-mount plastic package
High DC current gain for signal amplification
Low collector capacitance for high-frequency performance

Applications

General-purpose small-signal switching
Low and medium frequency AC applications
Mobile device circuitry

Procurement Notes

Verify the specific suffix /ZLX against official Nexperia documentation to confirm tape-and-reel specifications or marking codes. Ensure compatibility with standard SOT323 footprints during procurement. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing orders.

Selection Notes

Select this component for designs requiring a compact PNP switch with moderate gain. The SOT323 package suits space-constrained PCB layouts. Compare hFE ranges and saturation voltages against alternative BJT families if precise biasing is required. Verify thermal management capabilities for the 200 mW power dissipation limit in enclosed environments.

Part Context

This part belongs to the Nexperia BC857W series, which includes complementary NPN devices like the BC847W. The series is designed for general-purpose use in consumer electronics. The ZLX suffix typically indicates specific packaging or reel configurations rather than altering the electrical characteristics of the silicon die.

Replacement Considerations

Direct substitutes include BC857AW,115 and BC857CW variants within the same family. Cross-reference pinouts and electrical tolerances carefully when replacing with generic PNP transistors from other manufacturers.
