BCR420UW6-7

Overview

The BCR420UW6-7 is a linear LED constant current regulator manufactured by Diodes Incorporated. It provides a nominal output current of 10 mA, adjustable up to 350 mA via an external resistor. The device supports a maximum supply voltage of 40 V and operates within a temperature range of -55°C to +150°C. It features a single channel with a SOT-26-6 package. The power dissipation capability is 1.19 W, and the maximum supply current is 10 mA. The component utilizes a linear topology for precise current regulation in LED applications.

Feature Summary

Integrates NPN emitter follower and emitter resistor for constant current regulation
Supports PWM dimming through external transistor control
Features negative temperature coefficient for thermal protection
Enables parallel connection to increase regulated current

Applications

LED string current control
General LED lighting drivers
Low-side controlled LED circuits

Procurement Notes

Verify the specific suffix UW6-7 corresponds to the SOT-26-6 package and reel packaging configuration. Confirm RoHS compliance status and AEC-Q101 qualification requirements against the latest manufacturer datasheet. Ensure the ordering part number matches the required current adjustment specifications and operating temperature range for the target application environment.

Selection Notes

Select this component when a compact linear solution is required for driving LED strings with voltages up to 40 V. Consider the 10 mA nominal current and adjustability up to 350 mA for load matching. Evaluate the SOT-26-6 package size constraints and the need for external components for PWM dimming functionality. Verify thermal management capabilities given the 1.19 W power dissipation limit in the chosen enclosure.

Part Context
