BRT22-F

Overview

The BRT22-F is a phototriac output optocoupler featuring an integrated zero-crossing detector. It operates with a peak repetitive off-state voltage of 600V and supports an RMS on-state current of 300 mA. The device exhibits high input sensitivity with a trigger current (IFT) of 1.2 mA and a static dv/dt rating of 10,000 V/µs. It utilizes a DIP-6 package and functions within a temperature range of -40°C to 100°C.

Feature Summary

• Integrated zero-voltage crossing detection for reduced electromagnetic interference
• High input sensitivity enabling direct microcomputer interface compatibility
• Robust electrical isolation between input LED and output triac circuits

Applications

• Solid-state relay driver circuits
• AC power switching control systems
• Motor speed control applications

Procurement Notes

Verify the specific suffix designation against official Vishay documentation to confirm pinout configuration and insulation ratings. Ensure the selected variant matches the required voltage class and package style for your design. Cross-reference ordering codes with manufacturer catalogs to avoid discrepancies in lead times or packaging formats.

Selection Notes

Select this component when precise AC phase control timing is critical due to its zero-crossing feature. Evaluate the 1.2 mA trigger current requirement against your driving circuit capabilities. Confirm that the 600V blocking voltage exceeds your system's peak line voltage requirements for adequate safety margins.

Part Context

This part belongs to the BRT21/BRT22/BRT23 family of optocouplers designed for AC load control. These devices combine a gallium arsenide infrared LED emitter with a silicon phototriac detector. The series is engineered for high reliability in industrial and consumer electronics requiring galvanic isolation.

Replacement Considerations

Check Vishay datasheets for compatible alternatives such as the BRT21-F or BRT23-F based on voltage and current specifications. Verify pin compatibility before substitution.
