BCM846BS-7

Overview

The BCM846BS-7 is a dual NPN matched pair small signal transistor manufactured by Diodes Incorporated. It utilizes an ultra-small SOT363 surface mount package and is qualified to AEC-Q101 standards for high reliability. The device features a collector-emitter breakdown voltage of 65V, a maximum collector current of 100mA, and a power dissipation rating of 200mW. Key electrical characteristics include a DC current gain (hFE) range of 200 to 450 at 2mA, a transition frequency of 100MHz, and tight matching parameters for both current gain and base-emitter voltage.

Feature Summary

• Current gain and base-emitter voltage matching between the two internal transistors
• Qualified to AEC-Q101 automotive standards for high reliability
• Totally lead-free and fully RoHS compliant with halogen and antimony free construction

Applications

• Switching applications
• Audio Frequency (AF) amplifier circuits

Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the 3,000-unit reel packaging configuration as documented in the manufacturer's ordering information. Confirm that the component meets the required environmental compliance standards, specifically the lead-free and halogen-free definitions provided by Diodes Incorporated. Ensure the sourcing channel is authorized to guarantee product authenticity and traceability.

Selection Notes

Select this component when space constraints require a dual NPN configuration in an SOT363 package. The AEC-Q101 qualification makes it suitable for automotive environments. Consider the 200mW power dissipation limit and thermal resistance of 625°C/W for heat management. Verify that the 65V collector-emitter voltage rating aligns with the circuit requirements.

Part Context

This part belongs to the BCM846BS series of matched pair transistors from Diodes Incorporated. The '-7' suffix indicates the specific tape and reel packaging format containing 3,000 units per reel. It serves as a compact solution for replacing standard discrete double transistors in automated assembly processes.

Replacement Considerations

Direct replacements must match the SOT363 footprint and provide equivalent NPN/NPN matching characteristics. Verify that substitute components meet the same AEC-Q101 automotive qualification and maintain similar hFE and VBE matching tolerances for circuit compatibility.
