BC846S-QZ

Overview

The BC846S-QZ is an NPN general-purpose double transistor manufactured by Nexperia. It is housed in a SOT-363 (SC-88) surface-mount device plastic package. The component features two internally isolated transistors within a single package, designed to reduce component count and board space. It is qualified according to AEC-Q101 standards for automotive applications. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 65 V, a maximum collector-base voltage (VCBO) of 80 V, and a maximum emitter-base voltage (VEBO) of 6 V. The continuous collector current is rated at 100 mA with a power dissipation of 300 mW. The gain-bandwidth product (fT) is 100 MHz, and the operating temperature range spans from -65 °C to +150 °C.

Feature Summary

• Dual NPN transistors integrated into a compact SOT-363 package for space-efficient designs
• Internally isolated transistor structures prevent mutual interference between elements
• AEC-Q101 qualification ensures suitability for demanding automotive electronic environments

Applications

• General purpose switching circuits
• Small signal amplification stages
• Automotive electronics systems requiring qualified components

Procurement Notes

Verify the specific suffix 'QZ' against official Nexperia documentation to confirm packaging details and availability status. Confirm that the AEC-Q101 qualification aligns with project requirements. Check for any end-of-life notices or production changes via manufacturer notifications before finalizing procurement plans.

Selection Notes

Select this component when dual NPN switching or amplification is required in a minimal footprint. The AEC-Q101 qualification makes it appropriate for automotive designs. Ensure the 65 V voltage rating and 100 mA current capacity meet circuit demands. Compare with standard BC846S variants if automotive qualification is not strictly necessary.

Part Context

This part belongs to the BC846 family of small-signal NPN transistors. The 'S' designation indicates the dual-transistor configuration in the SOT-363 package. The 'Q' suffix typically denotes AEC-Q101 automotive qualification. This variant serves as a drop-in replacement for standard dual transistors where size and isolation are critical.

Replacement Considerations

BC846S-Q is a related variant with similar specifications. Standard BC846S parts may lack automotive qualification. Verify pinout compatibility and thermal characteristics when substituting with other dual NPN transistors in the SC-88 package family.
