BC846S-QH

Overview

The BC846S-QH is an NPN general-purpose double transistor manufactured by Nexperia. It is housed in a SOT363-3 (SC-88) Surface-Mounted Device plastic package, containing two fully isolated transistors within a single component to reduce board space and part count. The device is qualified according to AEC-Q101 standards, making it suitable for automotive applications. Key electrical specifications include a maximum collector current of 100 mA, a collector-emitter voltage (VCEO) of 65 V, a collector-base voltage (VCBO) of 80 V, and an emitter-base voltage (VEBO) of 6 V. The power dissipation is rated at 300 mW, with a gain-bandwidth product (fT) of 100 MHz. The operating temperature range spans from -65 °C to +150 °C.

Feature Summary

• AEC-Q101 qualified for automotive reliability requirements
• Two fully isolated NPN transistors integrated in one compact SMD package
• Designed as a drop-in replacement for standard double transistors

Applications

• General purpose switching circuits
• Small signal amplification stages

Procurement Notes

Verify the specific suffix 'QH' against official Nexperia documentation to confirm tape and reel packaging details and binning specifications. Ensure the selected variant meets the required AEC-Q101 qualification level for your target automotive application. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing processes and environmental compliance standards.

Selection Notes

Select this component when space-constrained designs require two matched or independent NPN transistors. The SOT363-3 package offers a small footprint ideal for dense PCB layouts. Consider the 100 mA current rating and 65 V voltage limits to ensure operation within safe boundaries. Verify thermal management requirements given the 300 mW power dissipation capability in the specified package.

Part Context

This part belongs to the BC846 series of general-purpose NPN transistors offered by Nexperia. The series includes various configurations such as single transistors in SOT23 and SOT323 packages, as well as other dual transistor variants like the BC846S. The BC846S-QH specifically targets the automotive market through its AEC-Q101 qualification, distinguishing it from standard commercial grade counterparts while maintaining similar electrical performance characteristics.

Replacement Considerations

Officially documented substitutes include the BC846S,115 and BC846SZ. These parts share the same SOT363-3 package and core NPN/NPN configuration. Verify that the substitute part number meets the specific AEC-Q101 automotive qualification requirements if applicable to your design.
