QTT2213ST1

Triac, SCR Output Optoisolators Overview

The QTT2213ST1 is a single-channel power Triac output optoisolator from the QTX213 series by QT Brightek. It provides 5000Vrms isolation voltage and features an integrated zero-crossing detection circuit for low electromagnetic interference switching. The device supports a maximum RMS on-state current of 900 mA with a 600 V off-state voltage rating. It operates within a temperature range of -55°C to 85°C and utilizes a 7-SMD surface-mount package.

Triac, SCR Output Optoisolators Feature Summary

• Integrated zero-crossing detection circuitry minimizes electrical noise during AC load switching
• High isolation voltage capability ensures safe separation between control and power circuits
• Power Triac output design enables direct driving of moderate current loads

Triac, SCR Output Optoisolators Applications

• Solid state relay modules requiring low-noise AC switching
• Industrial motor control interfaces
• AC power supply regulation systems

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix ST1 against official datasheets to confirm the 7-SMD package configuration and tape-and-reel orientation. Ensure compatibility with the required isolation voltage ratings for your specific application safety standards before finalizing procurement orders.

Triac, SCR Output Optoisolators Selection Notes

Select this component when high isolation voltage and low EMI are critical requirements. The zero-crossing feature distinguishes it from random-phase alternatives, making it suitable for applications where switching transients must be minimized. Verify that the 900 mA current rating meets the load requirements.

Triac, SCR Output Optoisolators Part Context

This part belongs to the QTX213 series of high-power Triac optoisolators. It shares architectural similarities with other members like the QTT0213ST1 but offers higher current handling capabilities. The series is designed for robust industrial applications requiring reliable AC switching with minimal signal interference.

Triac, SCR Output Optoisolators Replacement Considerations

Check for pin-compatible alternatives within the same manufacturer's portfolio that match the 7-SMD footprint. Verify that any substitute maintains the 5000Vrms isolation rating and zero-crossing functionality to ensure system performance parity.
