AL5890-40Y-13

Overview

The AL5890-40Y-13 is a constant current LED driver manufactured by Diodes Incorporated. It utilizes a single-transistor topology and features an integrated high-voltage switch capable of handling up to 400 V supply voltage. The device provides a fixed output current of 40 mA, making it suitable for driving LEDs in linear configurations. It is housed in a TO252 package and operates within a temperature range of -40°C to +105°C. This component is designed for efficient LED lighting applications requiring stable current regulation.

Feature Summary

• Integrates a high-voltage internal switch for simplified circuit design
• Provides fixed constant current output for consistent LED brightness
• Supports wide input voltage range up to 400 V

Applications

• General LED lighting fixtures
• LED replacement lamps
• Industrial LED indicators

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's latest documentation to confirm pinout and electrical characteristics, as suffixes often denote specific tape-and-reel packaging or regional compliance variations. Confirm RoHS status and lead times directly with authorized distributors, as availability may vary. Ensure the TO252 package footprint matches the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when a linear LED driver with high-voltage tolerance is required. The 40 mA output current is appropriate for standard indicator LEDs or low-power lighting strings. Consider thermal management requirements due to linear operation, especially at higher input voltages. Compare with other AL5890 variants if different current ratings or package types are needed for the specific application constraints.

Part Context

This part belongs to the AL5890 series of constant current LED drivers from Diodes Incorporated. The series offers various output currents and package options to accommodate diverse LED lighting needs. The AL5890-40Y-13 specifically denotes the 40 mA variant in a TO252 package with specific packaging suffixes. It serves as a cost-effective solution for simple LED drive circuits without complex switching regulators.

Replacement Considerations

Check for direct substitutes within the AL5890 family with matching 40 mA output and TO252 package. Verify compatibility with other manufacturers' high-voltage linear LED drivers if sourcing alternatives. Ensure pin-to-pin compatibility and identical electrical specifications to avoid redesigning the host circuit.
