STK760-221A-E

Overview

The STK760-221A-E is a thick-film hybrid integrated circuit designed for power factor correction in single-phase AC power supplies. It integrates an IGBT-based step-up active converter with average current control logic. The device operates within a supply voltage range of 14.5V to 17V, with a nominal voltage of 15V and a maximum supply current of 20mA. It features a 12-pin SIP-18 flange mount package suitable for through-hole installation. The component supports operation temperatures from -20°C to 100°C and includes built-in over-current, over-voltage, and low-voltage protection circuits.

Feature Summary

• Integrates IGBT power switching devices for the step-up active converter stage.
• Implements average current control methodology for power factor improvement.
• Includes soft start functionality to manage inrush conditions.
• Provides comprehensive protection against over-current, over-voltage, and low-voltage states.

Applications

• Single-phase rectification active filters
• Power factor correction for air conditioner power supplies
• Power factor correction for general-purpose inverters

Procurement Notes

Verify the manufacturer origin carefully, as this part was originally developed by Sanyo Semicon Device and later transferred to onsemi. Confirm that the specific suffix '-E' denotes the correct environmental compliance status and pin configuration required for your design. Ensure the supplier provides documentation tracing the lineage from Sanyo to onsemi to guarantee authenticity and technical accuracy.

Selection Notes

Select this component when designing single-phase AC power supplies requiring high power factor correction. It is appropriate for applications needing integrated protection and soft-start capabilities without external discrete components. Consider the SIP-18 flange mount package for thermal management requirements. Verify that the input voltage range and control signal compatibility match the system architecture before integration.

Part Context

This hybrid IC belongs to the STK760 series of active converter modules. It is functionally related to parts like the STK760-211C-E but may differ in specific internal parameters or packaging details. The series is characterized by its use of thick-film technology to combine power devices and control logic into a single compact unit for efficient power processing.

Replacement Considerations

The STK760-211C-E is a similar single-phase rectification active converter hybrid IC. Verify if the electrical characteristics and pinout are compatible for direct substitution. Other variants in the STK760 family, such as the STK760-213 series, may offer different specifications and require careful evaluation before replacement.
