BC857BS-TP

Overview

The BC857BS-TP is a dual PNP bipolar junction transistor array manufactured by Micro Commercial Components. It integrates two matched PNP transistors in a single SOT-363 surface-mount package. The device supports a maximum collector-emitter voltage of 45V and a continuous collector current of 200mA per transistor. Key electrical characteristics include a transition frequency of 200MHz, a maximum power dissipation of 300mW, and a DC current gain (hFE) minimum of 220 at 2mA and 5V. The saturation voltage is specified at 650mV under standard test conditions.

Feature Summary

• Dual PNP configuration within a compact SOT-363 footprint for space-constrained designs
• High current handling capability with 200mA collector current rating
• Matched transistor pairs ensuring consistent performance characteristics

Applications

• General-purpose switching circuits requiring dual PNP control
• Audio frequency amplifier stages utilizing matched transistor pairs

Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure compliance with project timelines. Confirm RoHS3 compliance status through the official datasheet or supplier documentation before integration into environmentally regulated assemblies. Check for any recent Product Change Notifications regarding packaging or assembly site updates that may affect supply chain continuity.

Selection Notes

Select this component when a dual PNP configuration is required in a small outline package. Ensure the application voltage does not exceed the 45V collector-emitter breakdown limit. Consider the 300mW power dissipation constraint for thermal management in enclosed spaces. Verify that the 200mA current rating meets the load requirements without exceeding safe operating area limits.
