IXCP10M45A

Current Regulation/Management Overview

The IXCP10M45A is a high-voltage current regulator manufactured by IXYS. It functions as a resistor-programmable constant current source with a minimum breakdown voltage of 450 V. The device supports a continuous power dissipation of 40 W and operates within a supply voltage range of 20 V to 450 V. It draws a typical operating supply current of 25 µA. Designed for through-hole mounting, it is housed in a TO-220-3 package. The component operates reliably across an extended temperature range from -55 °C to +150 °C.

Current Regulation/Management Feature Summary

Current Regulation/Management Procurement Notes

Verify the specific suffix (A vs S) against the datasheet to confirm pinout and package variations. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation. Ensure the selected package matches the PCB footprint requirements. Validate thermal management solutions for the 40 W dissipation rating under actual operating conditions.

Current Regulation/Management Selection Notes

Select this component when a high-side current regulation solution is required for voltages exceeding standard low-voltage regulators. The TO-220-3 package facilitates efficient heat sinking for high-power applications. Consider the 20 V minimum supply voltage constraint when designing the input stage. The resistor-programmable feature allows for flexible current setting without complex control loops.

Current Regulation/Management Part Context

The IXCP10M45A belongs to the IXYS IXCP series of high-voltage current regulators. This family is designed for applications requiring precise current control in harsh electrical environments. The 'A' suffix typically denotes a specific package or testing variant within the series. IXYS specializes in power management semiconductors, including MOSFETs, IGBTs, and discrete components.

Current Regulation/Management Replacement Considerations

The IXCP10M45S is a related variant in the same product line. Verify if the S suffix indicates a different package type or electrical tolerance before substitution. Cross-reference pinouts and thermal characteristics to ensure compatibility with existing designs.
