IXCY10M45S-TRL

Current Regulation/Management Overview

The Littelfuse IXCY10M45S-TRL is a switchable current regulator housed in a TO-252AA package. It features a minimum breakdown voltage of 450 V and provides a resistor-programmable constant current source with 40 W continuous power dissipation. The device operates within a temperature range of -55°C to +150°C and supports on/off switching functionality for precise current control.

Current Regulation/Management Feature Summary

• Resistor-programmable constant current source capability
• High-voltage operation with 450 V minimum breakdown
• On/off switchable current regulation
• 40 W continuous power dissipation capacity

Current Regulation/Management Applications

• Start-up circuits for SMPS
• Surge limiters and voltage protection
• Instantaneously reacting resettable fuses
• Soft start-up circuits

Current Regulation/Management Procurement Notes

Verify the specific suffix TRL indicates tape-and-reel packaging configuration against official Littelfuse documentation. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the TO-252AA footprint matches the target PCB layout requirements.

Current Regulation/Management Selection Notes

Select this component when designing high-voltage current regulation circuits requiring programmable output. The 450 V breakdown rating suits applications exceeding standard low-voltage limits. Evaluate thermal management needs given the 40 W dissipation rating in the TO-252AA package.

Current Regulation/Management Part Context

This part belongs to the IXCY series of switchable current regulators manufactured by Littelfuse (formerly IXYS). It is designed for robust performance in power electronics, offering reliable current limiting and regulation in compact surface-mount packages suitable for automated assembly processes.

Current Regulation/Management Replacement Considerations

The IXCP10M45A is listed as a similar high-voltage current regulator from the same manufacturer family. Verify pinout compatibility and exact current programming ranges before substitution.
