Overview
The BCR401WH6327XTSA1 is a single-transistor digital LED driver manufactured by Infineon Technologies. It is housed in an SOT-343 surface-mount package and designed for linear current regulation. The device provides a fixed output current of 60mA with an input voltage rating of 18V. It complies with RoHS3 standards and carries an EAR99 classification. This component serves as a dedicated solution for driving LEDs in automotive and industrial applications requiring precise current control.
Feature Summary
- Integrated linear current source functionality for stable LED operation
- Single NPN transistor topology with built-in biasing resistors
- Automotive-grade reliability compliant with AEC-Q101 standards
Applications
- Automotive exterior lighting systems
- Interior ambient LED illumination
- Industrial indicator lamps
- General-purpose LED current regulation
Procurement Notes
Verify the specific suffix WH6327XTSA1 against official Infineon documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SOT-343 housing. Confirm that the 60mA output current aligns with the target LED forward current requirements before finalizing procurement orders.
Selection Notes
Select this component when a simple, cost-effective linear current source is required for low-power LED applications. It is suitable for designs where thermal management can handle the dissipation at 18V input. Consider alternative topologies if higher efficiency or variable current control is necessary, as this device offers fixed regulation without external programming components.
Part Context
This part belongs to Infineon's BCR series of pre-biased transistors and LED drivers. These devices integrate internal resistors to simplify circuit design by reducing component count. The BCR401 variant specifically targets applications needing a reliable, fixed-current drive for single LEDs in constrained spaces.
Replacement Considerations
Public sources indicate this product is obsolete and no longer manufactured. Engineers should consult Infineon's official obsolescence notices for recommended replacement parts within the BCR series or equivalent automotive-grade LED drivers.
