BC846BPN/DG/B3X

Overview

The BC846BPN/DG/B3X is a dual NPN general-purpose transistor manufactured by Nexperia. It features two fully isolated NPN transistors housed in a compact SOT-363 (SC-88) surface-mount plastic package. The device supports a maximum collector current of 100 mA and a collector-emitter voltage of 65 V. Key electrical characteristics include a DC current gain (hFE) range of 200 to 450 for the 'B' suffix variant, a transition frequency of 100 MHz, and a power dissipation rating of 200 mW. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Dual NPN configuration with internal isolation between transistors
• Compact SOT-363 surface-mount packaging for space-constrained designs
• High DC current gain suitable for amplification applications

Applications

• Current mirror circuits
• Differential amplifier stages
• General-purpose switching and logic interfaces

Procurement Notes

Verify the specific suffix codes against official Nexperia documentation to confirm exact binning and packaging specifications. Ensure compatibility with standard SMT reflow profiles and check for AEC-Q101 qualification if automotive reliability standards are required for the design.

Selection Notes

Select this component when a matched pair of NPN transistors is needed in a minimal footprint. The SOT-363 package offers a drop-in replacement option for other dual transistor configurations. Consider the 200 mW power dissipation limit and thermal management requirements for high-density PCB layouts.

Part Context

This part belongs to the BC846 series of small-signal bipolar junction transistors. It serves as the dual-transistor counterpart to single units like the BC846B. The 'DG' code typically indicates a specific tape and reel packaging format used for automated assembly processes.
