STK760-223A-E

Overview

The STK760-223A-E is a thick-film hybrid integrated circuit designed for single-phase rectification active power factor correction. It integrates IGBT power switching devices, control logic, and protection circuits including over-current, over-voltage, and low-voltage detection. The component operates with an average current control topology to improve the power factor of single-phase AC power supplies. It features soft-start functionality and logic-level input control for ON/OFF operations. The device supports output voltage adjustment via external control signals and is housed in a flange-mount package suitable for high-power thermal management applications.

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with required protection thresholds and pin configurations. Confirm that the flange-mount package variant matches the thermal design requirements of the target application board. Cross-reference the ordering number with official onsemi documentation to distinguish between similar STK760 series variants.

Selection Notes

Select this component when designing single-phase AC power supplies requiring active power factor correction. Ensure the system architecture supports average current mode control and that the thermal solution accommodates the flange-mount package. Verify that the control interface aligns with the logic-level input requirements and that the available control signals are sufficient for the desired output voltage regulation range.

Part Context

This part belongs to the STK760 series of thick-film hybrid ICs from onsemi (formerly Sanyo Semicon Device). These components are specialized for power electronics applications, combining discrete power devices with control circuitry in a single module. The series is engineered for reliability in industrial and consumer power supply environments where space constraints and thermal performance are critical factors.

Replacement Considerations

Direct substitutes within the same family include the STK760-211C-E and STK760-213A-E. Verify functional equivalence regarding protection thresholds and control logic before substitution. Review the specific datasheet for each candidate to confirm pinout compatibility and electrical parameter alignment.
