BCR 141T E6327

Overview

The Infineon BCR 141T E6327 is an NPN silicon digital transistor housed in a SC74 package. It features built-in bias resistors with R1 and R2 both at 22 kΩ, yielding a typical resistor ratio of 1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. Total power dissipation is rated at 250 mW, with a junction temperature limit of 150 °C. Key electrical characteristics include a DC current gain (hFE) of 50 minimum at IC = 5 mA, a transition frequency (fT) of 130 MHz, and a collector-emitter saturation voltage (VCEsat) of 0.3 V maximum.

Feature Summary

• Integrated dual bias resistors for simplified circuit design
• High switching speed suitable for interface and driver applications
• Robust thermal performance with defined junction-to-soldering point resistance

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm the SC74 package configuration, as the base part number covers multiple packages. Confirm RoHS compliance status through official documentation before integration. Ensure the supply chain provides genuine Infineon components to maintain specified electrical tolerances and reliability standards.

Selection Notes

Select this component when a single NPN digital transistor with 22 kΩ input and emitter resistors is required in a compact surface-mount form factor. The SC74 package offers a smaller footprint compared to standard SOT-23 while maintaining similar electrical ratings. Consider the 100 mA current limit and 50 V voltage rating against load requirements.

Part Context

This component belongs to the BCR141 family of NPN silicon digital transistors from Infineon Technologies. The family includes variants with different internal resistor values and package types such as SOT-23, TSFP-3, and SOT363. The 'T' designation specifically identifies the SC74 package variant within this series.

Replacement Considerations

Direct substitutes must match the NPN polarity, 22kΩ/22kΩ resistor configuration, and SC74 package dimensions. Verify that alternative parts meet or exceed the 50 V VCEO, 100 mA IC, and 250 mW Ptot specifications.
