BRT22-H

Overview

The BRT22-H is a phototriac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a 600V blocking voltage and operates within a temperature range of -40°C to +115°C. The device incorporates an integrated zero-crossing detection circuit, ensuring triac triggering occurs near the AC line voltage zero point to minimize electromagnetic interference. It utilizes a 6-pin DIP package and provides 5300Vrms isolation between input and output channels.

Feature Summary

• Integrated zero-crossing detection circuit for low EMI switching
• High isolation voltage rating of 5300Vrms
• 600V peak repetitive off-state voltage capability
• DIP-6 package construction

Applications

• Solid-state relay driver circuits
• AC motor control systems
• Industrial process control interfaces
• Power supply feedback loops

Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet, as designations like 'H' or '-e3' indicate lead-free compliance and packaging variations. Confirm the exact part number with the supplier to ensure compatibility with existing PCB footprints and thermal requirements. Check for obsolescence notices or alternative series recommendations from Vishay before finalizing procurement plans.

Selection Notes

Select this component when zero-crossing switching is required to reduce electrical noise in AC power applications. Ensure the load current does not exceed the internal triac ratings. Verify that the isolation voltage meets the safety standards of the target equipment. Consider the DIP-6 package constraints for board layout and thermal management during high-duty cycle operations.

Part Context

This device belongs to the BRT21/BRT22/BRT23 family of Vishay optocouplers. These components are designed for general-purpose AC power switching applications. The family shares similar internal architectures but varies in voltage ratings and specific package configurations to suit different industrial and consumer electronics requirements.

Replacement Considerations

Consult the official Vishay datasheet for direct pin-compatible alternatives within the same product family. Verify that any substitute maintains the 600V rating and zero-crossing functionality. Cross-reference isolation voltages and package dimensions to ensure mechanical fit.
