BCR402UW6-7

Overview

The BCR402UW6-7 is a linear LED constant current regulator manufactured by Diodes Incorporated. It integrates a transistor, diodes, and resistors to function as a single-channel driver with an output current range of 20 mA to 100 mA. The device supports a supply voltage input from 1.4 V to 40 V and delivers up to 40 V output voltage. It operates within a junction temperature range of -55°C to +150°C and is housed in an SOT-26 surface-mount package.

Feature Summary

• Monolithic integration of transistor, diodes, and resistors for compact design
• Linear topology providing stable constant current regulation
• Wide input voltage range supporting low-voltage start-up

Applications

• LED lighting drivers
• Automotive interior illumination
• General-purpose LED indicator circuits

Procurement Notes

Verify the specific output current setting required for your application, as the BCR402UW6-7 supports a range rather than a fixed value. Confirm that the SOT-26 package footprint matches your PCB layout. Ensure the thermal management strategy accounts for power dissipation at maximum load conditions. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a simple, cost-effective linear solution is preferred over switching regulators. It is suitable for applications requiring a wide input voltage range and high reliability. Consider the thermal performance in enclosed spaces. Compare against other BCR series parts if different current levels or automotive qualification (Q-suffix) are needed.

Part Context

This part belongs to the BCR series of linear LED constant current regulators from Diodes Incorporated. These devices are designed to simplify LED driving by integrating necessary control components into a single small package. The series offers various current settings to accommodate different LED types and brightness requirements across consumer and industrial applications.

Replacement Considerations

Direct substitutes include other BCR4xxUW6 variants with similar current ratings. For automotive-grade requirements, consider the BCR402UW6Q-7. Verify pin compatibility and thermal characteristics before swapping.
