BCR146E6327HTSA1

Overview

The BCR146E6327HTSA1 is an NPN silicon digital transistor manufactured by Infineon Technologies. It integrates a single NPN bipolar junction transistor with an internal base resistor, housed in a surface-mount SOT-23-3 package. The component is qualified under the AEC-Q100 standard for automotive applications. Key electrical ratings include a maximum collector-emitter voltage (VCEO) of 50 V and a maximum power dissipation of 250 mW. The typical input resistance is specified at 47 kΩ. The device supports a maximum operating temperature of +150 °C and is supplied in tape-and-reel packaging.

Feature Summary

• Integrated base resistor simplifies circuit design by reducing external component count.
• AEC-Q100 qualification ensures reliability for demanding automotive environments.
• High thermal stability allows operation up to +150 °C junction temperature.

Applications

• Automotive logic switching circuits
• Driver interface stages in vehicle electronics
• General-purpose digital buffering

Procurement Notes

Verify the specific suffix E6327HTSA1 against official Infineon documentation to confirm the exact reel configuration and RoHS compliance status. Confirm current production status as some variants in this series may be subject to end-of-life notices. Ensure the ordering quantity matches the manufacturer's standard packaging multiples to avoid additional handling fees or cut-tape premiums.

Selection Notes

Select this component when a compact NPN digital switch with a 47 kΩ base resistor is required. Compare the 50 V VCEO rating against the system's supply voltage to ensure adequate headroom. Verify that the SOT-23-3 footprint aligns with the PCB layout constraints. Consider the 250 mW power dissipation limit relative to the expected load current and ambient temperature conditions.

Part Context

This part belongs to the BCR1xx series of NPN digital transistors from Infineon. These devices are designed to replace discrete resistor-transistor combinations, saving board space. The BCR146 specifically features a 47 kΩ internal resistor, distinguishing it from other series members like the BCR116 or BCR126 which have different resistance values.

Replacement Considerations

Check for direct cross-reference equivalents such as the BCR146 from other manufacturers offering identical pinouts and electrical characteristics. Verify that any substitute maintains the AEC-Q100 qualification if used in automotive contexts. Ensure the replacement package is strictly SOT-23-3 to fit existing footprints.
