BC846SZ

Overview

The BC846SZ is a dual NPN bipolar junction transistor manufactured by Nexperia, housed in a TSSOP-6 (SOT363/SC-88) surface-mount package. It features a maximum DC collector current of 100 mA and a collector-emitter voltage (VCEO) of 65 V. The device has a collector-base voltage (VCBO) of 80 V and an emitter-base voltage (VEBO) of 6 V. Key electrical parameters include a collector-emitter saturation voltage of 300 mV, power dissipation of 300 mW, and a gain-bandwidth product (fT) of 100 MHz. Operating temperatures range from -65 °C to +150 °C.

Feature Summary

• Dual NPN configuration within a compact SMD plastic package
• Low collector-emitter saturation voltage for efficient switching
• High-temperature operation capability up to 150 °C

Applications

• General-purpose switching circuits
• Amplification applications
• Automotive electronics requiring high-temperature stability

Procurement Notes

Verify the specific suffix 'Z' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with SOT363 footprint requirements during PCB layout. Cross-reference RoHS compliance status directly with the manufacturer's latest environmental declaration before procurement.

Selection Notes

Select this component when space-constrained designs require two matched NPN transistors in a single package. The 65 V rating suits low-voltage logic interfacing. Verify that the 300 mW power dissipation limit aligns with thermal management capabilities in the target enclosure under expected load conditions.

Part Context

This part belongs to the BC846 series of small-signal NPN transistors. It serves as the dual-transistor variant in the SOT363 package, complementing single-transistor options like the BC846W in SOT323. The series provides general-purpose switching solutions with standardized pinouts for easy integration into consumer and industrial electronics.

Replacement Considerations

Direct functional substitutes include BC846S,115 which shares identical electrical characteristics and SOT363 packaging. Verify pinout compatibility and thermal resistance values when substituting with other dual NPN devices in similar small-outline packages.
