BC856BS-TPQ2

Overview

The BC856BS-TPQ2 is a PNP plastic-encapsulated transistor manufactured by Micro Commercial Components. It features an internal multi-chip structure in an SOT-363 package with marking '5Ft'. Key electrical ratings include a collector current of -100 mA, collector power dissipation of 200 mW, and collector-emitter voltage of -65 V. The device operates within a junction temperature range of -55°C to +150°C. Electrical characteristics specify a DC current gain (hFE) of 200 to 450 at IC=-2mA, a transition frequency of 100 MHz, and a collector-base cutoff current of 15 nA maximum.

Feature Summary

• Multi-chip transistor configuration for signal processing applications
• Halogen-free green device compliant with UL 94 V-0 flammability rating
• Moisture sensitivity level 1 classification for standard handling

Applications

• General-purpose switching circuits
• Audio frequency amplifier stages
• Signal conditioning in consumer electronics

Procurement Notes

Verify the authenticity of the BC856BS-TPQ2 component by purchasing exclusively from authorized Micro Commercial Components distributors or directly from the manufacturer. Ensure the ordering suffix matches the specific tape and reel packing format of 3K pieces per reel as defined in the official documentation. Counterfeit avoidance requires strict adherence to verified supply chain channels.

Selection Notes

Select the BC856BS-TPQ2 when a dual PNP transistor solution in an SOT-363 package is required. The device offers a thermal resistance of 625°C/W junction to ambient and supports operation up to 150°C. Confirm that the -100 mA collector current and -65 V breakdown voltage meet the circuit requirements before integration into the design.

Part Context

This component belongs to the BC856 series of PNP transistors produced by Micro Commercial Components. The TPQ2 designation indicates a specific packaging variant supplied in tape and reel format. The part utilizes a multi-chip architecture housed in the compact SOT-363 surface-mount package, distinguishing it from single-transistor equivalents in smaller footprints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided datasheet. Engineers should consult official cross-reference guides or contact the manufacturer for validated alternatives that match the SOT-363 footprint and electrical specifications.
