STK760-211A-E

Overview

The STK760-211A-E is a single-phase rectification Active Converter Hybrid IC designed for power factor improvement in single-phase AC power supplies. It utilizes average current control and integrates IGBT-based step-up active converter power devices with an internal control IC. The component includes over-current, over-voltage, and low-voltage protection circuits, along with soft-start functionality. It operates within a supply voltage range of 14.5V to 17V and supports logic-level ON/OFF control input signals.

Feature Summary

• Integrates IGBT power switching devices for the step-up active converter
• Includes built-in soft start, over-current, over-voltage, and low-voltage protection circuits
• Supports output voltage changeability via external control signal
• Enables ON/OFF control through logic level input signal

Applications

• Single-phase rectification active filter for air conditioners
• Power rectification for general-purpose inverters

Procurement Notes

Verify the specific suffix 'A' against official manufacturer documentation to confirm pinout and electrical characteristics, as variations exist within the STK760 series. Ensure compatibility with single-phase AC power supply requirements. Confirm RoHS compliance status and lead-free certification prior to integration into final designs.

Selection Notes

Select this hybrid IC for applications requiring high power factor correction in single-phase systems. The integrated protection features simplify design complexity by eliminating external protection components. Consider the SIP-18 package constraints and thermal management requirements for flange mount installation when designing the PCB layout.

Part Context

This component belongs to the STK760 series of thick-film hybrid ICs originally developed by Sanyo Semicon Device and later managed by onsemi. These devices are specialized for power factor correction (PFC) in residential and commercial appliances. The series typically combines power semiconductors with control logic in a robust ceramic package suitable for high-reliability environments.

Replacement Considerations

STK760-211C-E: Verify if functional differences exist between the A and C suffixes regarding pin configuration or protection thresholds before substitution.
