STK760-211C-E

Overview

The STK760-211C-E is a single-phase rectification Active Converter Hybrid IC designed for power factor improvement in single-phase AC power supplies. It integrates IGBT-based step-up active converter power devices, control IC logic, and protection circuits including over-current, over-voltage, and low-voltage detection. The device operates with a supply voltage range of 14.5V to 17V and supports logic-level ON/OFF control. It utilizes an 18-pin SIP flange mount package suitable for through-hole installation.

Feature Summary

• Integrates IGBT power switching devices for the step-up active converter stage
• Includes soft start functionality alongside over-current, over-voltage, and low-voltage protection circuits
• Supports output voltage adjustment via external control signals
• Enables system ON/OFF control through a logic level input signal

Applications

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

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity for the 18-pin SIP form factor. Ensure the specific suffix matches the required electrical characteristics. Cross-reference ordering numbers with authorized distribution channels to avoid counterfeit components. Validate RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this hybrid IC for designs requiring integrated PFC correction in single-phase AC systems. The inclusion of built-in protection circuits reduces external component count. Verify that the operating temperature range meets the application requirements. Ensure the control interface aligns with the system's logic levels. Consider the thermal management needs associated with the flange mount package configuration.

Part Context

This component belongs to the STK760 series of thick-film hybrid ICs originally developed by Sanyo Semicon Device, now part of onsemi. These devices are specialized for power factor correction in residential and light commercial electronics. The series focuses on integrating power and control functions into a compact module to simplify circuit design and improve reliability in single-phase power conversion tasks.

Replacement Considerations

STK760-211-E is a similar variant within the same product family offering comparable single-phase rectification capabilities. Verify pin compatibility and electrical parameters before substitution. Other models like STK760-221A-E may offer different performance characteristics. Always consult the latest datasheets to confirm functional equivalence and mechanical fit.
