BC856S-TP

Overview

The BC856S-TP is a dual PNP bipolar junction transistor (BJT) manufactured by Micro Commercial Components. It integrates two independent PNP transistors within a single SOT-323 package, designed for surface-mount applications. The device supports a collector-emitter voltage of -65V and a collector-base voltage of -80V. Maximum continuous collector current is rated at -100mA per transistor. Total power dissipation is limited to 150mW. The component operates across a junction temperature range of -55°C to +150°C.

Feature Summary

• Dual configuration integrating two independent PNP transistors in a compact SOT-323 package
• High breakdown voltage ratings with -80V collector-base and -65V collector-emitter limits
• Extended thermal operating range supporting junction temperatures up to +150°C

Applications

• General-purpose signal switching circuits
• Low-power amplifier stages
• Logic level translation interfaces

Procurement Notes

Verify the specific datasheet version provided by the manufacturer before integration, as electrical characteristics may vary between production batches. Confirm that the SOT-323 footprint matches the design layout requirements. Ensure compliance with RoHS directives if required by the final assembly specifications. Check for any recent Product Change Notifications regarding packaging or material composition updates.

Selection Notes

Select this component when space constraints require dual PNP functionality in a minimal footprint. The SOT-323 package offers lower parasitic effects compared to larger through-hole alternatives. Consider the 150mW total power dissipation limit when designing thermal management strategies. Verify that the -100mA current rating meets the load requirements of the target circuit application.

Part Context

This part belongs to the BC856S series of dual PNP transistors from Micro Commercial Components. It serves as a compact alternative to discrete single transistors, reducing board space and assembly complexity. The TP suffix indicates standard tape and reel or cut tape packaging options suitable for automated surface-mount technology processes.

Replacement Considerations

Direct pin-compatible substitutes include other manufacturers' BC856S variants. Verify electrical parameters such as hFE ranges and saturation voltages match the original design requirements before substitution.
