BC847BS/ZLX

Overview

The BC847BS/ZLX is a dual NPN general-purpose transistor manufactured by Nexperia. It integrates two isolated transistors within a SOT363 (SC-88) surface-mount plastic package, measuring 2.2 mm x 1.25 mm x 0.8 mm. The device supports a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA. Key electrical parameters include a collector-base voltage of 50 V, an emitter-base voltage of 5 V, and a total power dissipation of 300 mW. The minimum DC current gain (hFE) is specified at 200 under standard test conditions.

Feature Summary

• Dual NPN configuration with internal isolation to prevent mutual interference between transistors
• Closely matched current gain characteristics for consistent performance in paired applications
• Low collector capacitance and low saturation voltage for efficient switching operations

Applications

• General-purpose switching circuits
• Signal amplification stages
• Digital logic interface buffers

Procurement Notes

Verify the specific suffix ZLX against official Nexperia documentation to confirm tape-and-reel specifications and packaging details. Ensure the component meets RoHS compliance requirements for your target assembly process. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity before procurement.

Selection Notes

Select this component when space-constrained designs require two matched NPN transistors in a single footprint. The SOT363 package offers reduced board area compared to discrete SC-75 or SC-89 packages. Consider the 45 V rating and 100 mA current limit to ensure operation remains within safe operating areas for the intended application load.

Part Context

This part belongs to the BC847 series of small-signal NPN transistors. The BS variant specifically denotes the dual NPN configuration housed in the compact SOT363 package. It serves as a complement to the BC857BS PNP/PNP pair, facilitating symmetrical circuit designs in minimal form factors.

Replacement Considerations

The BCM846BS is a qualified AEC-Q101 alternative offering similar dual NPN functionality in the same SOT363 package. Designers should verify pinout compatibility and thermal characteristics before substituting components in existing layouts.
