BC846S/ZLX

Overview

The BC846S/ZLX is a dual NPN bipolar junction transistor (BJT) manufactured by Nexperia USA Inc. It is housed in a TSSOP-6 (SC-88/SOT-363) surface-mount package. The device features a maximum collector current of 100 mA and a collector-emitter voltage rating of 65 V. Key electrical parameters include a collector-base voltage of 80 V, an emitter-base voltage of 6 V, and a power dissipation capacity of 300 mW. The transition frequency is specified at 100 MHz, with a saturation voltage of 300 mV. Operating temperatures range from -65°C to +150°C.

Feature Summary

• Dual NPN configuration within a single compact SMD package
• Internally isolated transistors preventing mutual interference
• AEC-Q101 qualified for automotive application reliability

Applications

• General purpose switching circuits
• Small signal amplification stages
• Automotive electronic systems requiring AEC-Q101 compliance

Procurement Notes

Verify the specific suffix ZLX against official Nexperia documentation to confirm tape-and-reel specifications and regional distribution channels. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to procurement. Ensure the ordering code matches the exact package variant required for your PCB footprint.

Selection Notes

Select this component when space-constrained designs require two matched NPN transistors in a SC-88 package. Consider the 100 mA current limit and 65 V voltage rating for circuit compatibility. Verify thermal management requirements given the 300 mW power dissipation limit in the small outline package.

Part Context

This part belongs to the BC846 series of general-purpose double transistors. It serves as a drop-in replacement for standard discrete dual transistors, reducing board space and component count. The series is widely used in consumer electronics and industrial control applications requiring small-signal processing.

Replacement Considerations

Direct pin-compatible alternatives include the BCM846BSX and BC846BS,135. Verify that substitute parts meet the same AEC-Q101 qualification if automotive use is intended. Check for differences in hFE gain ranges and saturation voltages between variants.
