BCR421UW6-7

Overview

The BCR421UW6-7 is a linear LED constant current regulator manufactured by Diodes Incorporated. It operates with an input voltage range of 1.4 V to 40 V and delivers a regulated output current of 350 mA. The device supports PWM dimming at frequencies up to 10 kHz. It is housed in a SOT-26 package and is qualified to AEC-Q101 standards for automotive applications. The component functions within a junction temperature range of -55°C to +150°C.

Feature Summary

Provides stable constant current regulation for single-channel LED loads
Supports high-frequency PWM dimming control for brightness adjustment
Operates reliably across extended industrial and automotive temperature ranges

Applications

Automotive exterior lighting systems
Interior vehicle illumination circuits
General-purpose LED indicator drivers

Procurement Notes

Verify the specific suffix W6-7 confirms the SOT-26 package and 350mA rating, as other variants exist. Confirm AEC-Q101 qualification requirements match your design specifications. Check RoHS compliance status against regional regulations. Ensure supply chain stability given potential long lead times associated with automotive-grade components.

Selection Notes

Select this component when a linear topology is preferred for simplicity and low noise in LED driving applications. It is suitable for designs requiring precise current regulation without complex switching circuitry. Consider thermal management capabilities due to power dissipation inherent in linear regulators. Verify input voltage headroom meets the minimum dropout requirements for reliable operation.

Part Context

This part belongs to the BCR421 series of linear LED drivers from Diodes Incorporated. It is designed specifically for high-reliability environments, including automotive electronics. The series offers various current ratings and packaging options to suit different LED power requirements and board space constraints.

Replacement Considerations

Direct substitutes include BCR420UW6-7 (100mA) and BCR430UW6-7 (100mA with dimming). Cross-reference pinouts and thermal characteristics before substitution. Verify that alternative parts meet the same AEC-Q101 automotive qualification standards.
