BC846BSS-TP

Overview

The BC846BSS-TP is a dual NPN bipolar junction transistor (BJT) array manufactured by Micro Commercial Components. It integrates two independent NPN transistors within a single SOT-363 surface-mount package, designed for signal amplification and switching applications. The device features a collector-emitter breakdown voltage of 65V and a maximum continuous collector current of 100mA per transistor. With a transition frequency of 100MHz and a total power dissipation rating of 200mW, it supports operation across a junction temperature range of -55°C to +150°C. The component ensures a minimum DC current gain (hFE) of 200 at specified test conditions, providing reliable performance in compact electronic designs.

Feature Summary

• Dual NPN configuration with galvanic isolation between internal transistors within a compact footprint
• High DC current gain ensuring efficient signal amplification capabilities
• Low collector-emitter saturation voltage for improved switching efficiency
• Robust thermal stability supporting extended operating temperature ranges

Applications

• General-purpose signal amplification circuits
• Portable equipment switching applications
• Driver stages for low-power loads

Procurement Notes

Verify the specific suffix 'S' against official MCC documentation to confirm pinout compatibility and electrical tolerances, as variations exist within the BC846 family. Ensure the ordering quantity aligns with manufacturer reel specifications. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing standards before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN solution is required in an SOT-363 package to save board space compared to discrete single transistors. Verify that the 65V breakdown voltage and 100mA current limits meet circuit requirements. Consider the 200mW power dissipation limit and ensure adequate thermal management or PCB copper area is allocated for the intended operating environment.

Part Context

This part belongs to the BC846 series of small-signal NPN transistors. While standard BC846 variants are single transistors in SOT-23 packages, the BC846BS/BC846BSS configurations integrate dual units. This specific model offers a compact alternative to using two separate discrete components, simplifying assembly and reducing overall footprint in dense circuit layouts.

Replacement Considerations

Compatible substitutes include other dual NPN arrays in SOT-363 packages such as the BC846BS from Nexperia or ON Semiconductor, provided pinouts match exactly. Single transistor replacements require two discrete BC846B units, increasing board space. Always verify hFE binning and saturation voltage specs against the original design requirements.
