BCR146T E6327

Overview

The Infineon BCR146T E6327 is an NPN silicon digital transistor housed in a SOT-23-3 surface-mount package. It features a typical input resistance of 22 kOhms and a typical resistor ratio of 1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 70 mA. Minimum DC collector/base gain (hfe) is specified at 50. Operating temperature range extends from -65 C to +150 C.

Feature Summary

• Integrates NPN bipolar junction transistor with built-in biasing resistors for simplified circuit design.
• Utilizes compact SOT-23-3 surface-mount packaging suitable for automated assembly processes.

Applications

• General-purpose switching applications
• Driver circuits for low-current loads
• Logic interface buffering

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific suffix matches the required electrical characteristics. Check for end-of-life status as discontinuation notices may affect long-term supply availability. Ensure storage conditions comply with moisture sensitivity levels defined in the datasheet to prevent package damage during soldering.

Selection Notes

Select this component when a single NPN digital transistor with moderate current capability is required. The 50 V rating suits low-voltage logic systems. The integrated 22 kOhm resistor simplifies base drive networks compared to discrete transistors. Verify that the 70 mA current limit meets load requirements before finalizing the design choice.

Part Context

This part belongs to Infineon's BCR series of pre-biased transistors. These components combine a single transistor with internal resistors to reduce board space and assembly time. The E6327 suffix indicates the specific tape-and-reel packaging configuration used for high-volume manufacturing integration.

Replacement Considerations

Consult official replacement lists for direct substitutes. Cross-reference pinouts and electrical ratings if considering alternative manufacturers. Ensure thermal dissipation characteristics match the original design constraints.
