BCR 146F E6327

Overview

The BCR 146F E6327 is a single NPN pre-biased bipolar junction transistor manufactured by Infineon Technologies. It integrates internal base and emitter resistors to simplify circuit design. The device features a collector-emitter voltage of 50 V, a continuous collector current of 70 mA, and a transition frequency of 150 MHz. It is housed in a PG-SOT23-3 surface-mount package with a maximum power dissipation of 250 mW. The component is qualified for automotive applications under the AEC-Q101 standard.

Feature Summary

• Integrates internal biasing resistors to reduce external component count
• Qualified for automotive electronics via AEC-Q101 certification
• High-speed switching capability with 150 MHz transition frequency
• Compact surface-mount packaging for space-constrained designs

Applications

• Automotive control unit logic interfaces
• General-purpose switching circuits
• Driver stages for low-power loads
• Signal level translation networks

Procurement Notes

Verify the specific suffix 'E6327' against official Infineon documentation to confirm tape-and-reel packaging specifications. Confirm that the AEC-Q101 qualification status aligns with your project's reliability requirements. Ensure the PG-SOT23-3 footprint matches your PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for high-speed switching. The 50 V rating suits low-voltage digital logic levels. Consider the 70 mA current limit for load driving capabilities. Verify thermal management needs given the 250 mW power dissipation in the small SOT-23 package.

Part Context

This part belongs to Infineon's BCR series of pre-biased transistors, designed to replace discrete resistor-transistor combinations. The F suffix typically denotes specific packaging or variant details within the product line. These devices are engineered to minimize board space and assembly complexity while maintaining reliable performance in demanding electronic environments.

Replacement Considerations

Check for direct cross-reference availability from other manufacturers offering identical pinouts and electrical characteristics. Verify that any substitute maintains the same AEC-Q101 automotive qualification if required. Ensure the replacement supports the 150 MHz frequency and 50 V voltage ratings without derating issues.
