BCR141TE6327

Overview

The BCR141TE6327 is an NPN silicon digital transistor manufactured by Infineon Technologies, belonging to the BCR141 series. It integrates a single NPN bipolar junction transistor with internal biasing resistors in a compact SOT-323 surface-mount package. Key electrical specifications include a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 25 kOhms and a resistor ratio of 0.47. It operates within a temperature range of -65°C to +150°C and has a power dissipation rating of 250 mW.

Feature Summary

• Integrates NPN transistor with built-in base biasing resistors for simplified circuit design
• Automotive qualified under AEC-Q101 standards for enhanced reliability
• Compact SOT-323 surface-mount packaging for space-constrained applications

Applications

• Switching applications in automotive electronics systems
• General-purpose digital switching circuits
• Level shifting and buffer stages in low-power logic interfaces

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific suffix corresponds to the SOT-323 package and AEC-Q101 qualification status required for your application. Request official datasheets and material declarations to ensure compliance with project specifications and regulatory requirements before finalizing procurement decisions.

Selection Notes

Select this component when a small-form-factor NPN digital switch with automotive reliability is required. Compare the 25 kOhm input resistance against other series members like BCR142 (22 kOhm) or BCR143 (10 kOhm) to match specific drive current requirements. Ensure the 100 mA collector current limit suffices for the load, and verify that the SOT-323 footprint aligns with the PCB layout constraints.

Part Context

This part belongs to Infineon's BCR14x family of digital transistors, which are designed to replace discrete resistor-transistor networks. The BCR141 variant specifically offers a higher input resistance compared to lower-numbered siblings, reducing standby power consumption while maintaining fast switching characteristics suitable for modern electronic control units.

Replacement Considerations

Direct pin-compatible substitutes within the same family include BCR141WH6327XTSA1. Cross-family replacements such as BCR142 or BCR143 require verification of input resistance differences. Always validate thermal performance and gain characteristics against the original design specifications when substituting.
