BC846BS-TPQ2

Overview

The BC846BS-TPQ2 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. The device features a maximum collector-emitter voltage of 65V and a continuous collector current rating of 100mA per transistor. Key electrical specifications include a DC current gain (hFE) of at least 200 at 2mA, a transition frequency of 100MHz, and a total power dissipation of 200mW. The component operates across a junction temperature range of -55°C to +150°C.

Feature Summary

• Dual NPN configuration with galvanic isolation between internal transistors
• High DC current gain for efficient signal amplification
• Low collector-emitter saturation voltage for improved switching efficiency
• Compact SOT-363 package suitable for space-constrained designs

Applications

• General-purpose signal amplification circuits
• Switching applications in low-power digital logic interfaces
• Driver stages for small-signal audio or RF pre-amplifiers

Procurement Notes

Verify the specific suffix 'Q2' against official MCC documentation to confirm AEC-Q101 automotive qualification status, as standard datasheets may list only 'TP'. Ensure the ordering part number matches the exact package marking and electrical grade required for your design. Cross-reference distributor listings for the precise suffix to avoid confusion with non-qualified variants.

Selection Notes

Select this component when a dual NPN solution is required in an SOT-363 footprint. Compare hFE bins and Vce(sat) values against circuit requirements. Consider thermal management if operating near the 200mW limit. Verify compatibility with PCB layout tools using the provided ECAD models for accurate footprint placement.

Part Context

This part belongs to the BC846 series of small-signal NPN transistors. Variants such as BC846B and BC846C differ primarily in their DC current gain ranges. The BS suffix typically denotes the dual-transistor array format in the SOT-363 package, distinguishing it from single-transistor packages like SOT-23.

Replacement Considerations

Direct substitutes include other manufacturers' dual NPN arrays in SOT-363, such as Nexperia BC846BS or ON Semiconductor MCZ2846BS. Verify pinout compatibility and ensure electrical parameters meet or exceed the original specifications.
