BCM846BSX

Overview

The BCM846BSX is an NPN/NPN matched double transistor manufactured by Nexperia USA Inc. It is housed in a TSSOP6 (SOT363-3) surface-mount package with six leads. The device features fully isolated internal transistors and is qualified under the AEC-Q101 standard for automotive applications. Key electrical parameters include a collector-emitter voltage of 65 V, a maximum collector current of 100 mA per transistor, and a total power dissipation of 200 mW per transistor at 25 °C ambient temperature. The DC current gain ranges from 200 to 450 at IC = 2 mA, with a typical transition frequency of 250 MHz.

Feature Summary

• Current gain matching between paired transistors
• Base-emitter voltage matching within 2 mV tolerance
• Fully isolated internal transistor structure
• AEC-Q101 qualification for automotive reliability

Applications

• Current mirror circuits
• Differential amplifier configurations

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and reel specifications. Confirm that the component status remains active and check for any recent revision history updates that may affect pinning or marking codes before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require matched NPN pairs with low base-emitter voltage mismatch. Ensure the application operates within the 65 V collector-emitter voltage limit and 100 mA current rating. Verify thermal management requirements given the 200 mW per-transistor dissipation limit in the SOT363-3 package.

Part Context

This part belongs to Nexperia's family of small-signal matched double transistors designed for compact surface-mount applications. It serves as a drop-in replacement for standard discrete double transistors while reducing board space and component count. The SOT363-3 package provides a minimal footprint suitable for high-density PCB layouts.

Replacement Considerations

BCM846BSH is the PNP/PNP complement counterpart within the same package family.
