BCR108SE6327BTSA1

Overview

The BCR108SE6327BTSA1 is an NPN silicon digital transistor from the Infineon BCR108 series, housed in a SOT-363 (SC-88) surface-mount package. It integrates two internally isolated transistors with good matching within a single multichip assembly. Key electrical specifications include a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device features a built-in bias resistor network consisting of R1 at 2.2 kΩ and R2 at 47 kΩ, yielding a typical resistor ratio of 0.047. It operates with a total power dissipation of 250 mW and supports junction temperatures up to 150 °C.

Feature Summary

• Includes built-in bias resistors (R1=2.2 kΩ, R2=47 kΩ) to simplify switching circuit design
• Qualified according to AEC-Q101 standards for automotive applications
• Pb-free construction compliant with RoHS directives

Applications

• Switching circuits
• Inverter circuits
• Interface circuits
• Driver circuits

Procurement Notes

Verify the specific ordering suffix E6327BTSA1 against official Infineon documentation to confirm reel packaging details and tape-and-reel orientation requirements. Ensure the component meets the required AEC-Q101 qualification level if deployed in automotive systems. Cross-reference the SOT-363 pinout configuration carefully during PCB layout to prevent misalignment with the footprint.

Selection Notes

Select this component when dual isolated NPN switching functionality is required in a minimal footprint. The integrated bias resistors reduce external component count compared to discrete transistor pairs. Verify that the 50 V collector-emitter voltage rating and 100 mA current capacity align with the target load requirements. Consider the thermal resistance characteristics for high-density board layouts.

Part Context

This part belongs to the BCR108 series, which includes variants like the BCR108 (SOT-23) and BCR108W (SOT-323). The 'S' designation specifically denotes the SOT-363 package containing two isolated transistors. This series is designed for general-purpose digital switching applications where space efficiency and simplified biasing are priorities.

Replacement Considerations

Direct substitutes must match the NPN digital transistor type, SOT-363 package, and internal resistor values (2.2k/47k). Verify equivalent voltage and current ratings. Check for compatible AEC-Q101 qualification if automotive reliability is mandated.
