BC856AT TR PBFREE

Overview

The BC856AT TR PBFREE is a PNP general-purpose small-signal transistor manufactured by Central Semiconductor Corp. It operates with a maximum collector current of 100 mA and a collector-emitter voltage rating of 65 V. The device features a minimum DC current gain (hFE) of 125 at specified test conditions. It is housed in an SOT-323 surface-mount package, suitable for automated assembly processes. The component supports a junction temperature range from -65°C to 150°C and has a maximum power dissipation of 225 mW.

Feature Summary

• PNP polarity configuration designed for general-purpose switching and amplification applications
• Low voltage and low current operation capabilities within standard small-signal parameters
• Surface-mount SOT-323 packaging optimized for automatic insertion and space-constrained designs

Applications

• General purpose switching circuits
• Audio frequency (AF) amplifier stages
• Driver applications for low-power loads

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through the manufacturer's latest certification documents. Ensure the SOT-323 footprint matches the target PCB design. Cross-reference the hFE binning requirements with the application circuit needs before finalizing procurement.

Selection Notes

Select this component for designs requiring a PNP counterpart to the BC846 series NPN transistors. The SOT-323 package offers a compact form factor compared to traditional SOT-23 options. Verify that the 65V breakdown voltage meets the circuit's peak operating requirements. Consider the thermal dissipation limits when designing for high ambient temperatures.
