Triac, SCR Output Optoisolators datasheet and documents for S21MT2

S21MT2

Triac, SCR Output Optoisolators Overview

The Sharp Microelectronics S21MT2 is a triac output optoisolator designed for AC load switching applications. It features a 5000Vrms isolation voltage between the input LED and output triac, ensuring robust electrical safety in high-voltage environments. The device operates with a zero-crossing circuit to minimize electromagnetic interference during switching events. Key electrical parameters include a maximum off-state voltage of 600V and a hold current of 3.5mA. The component is housed in a 4-DIP package and supports through-hole mounting.

Triac, SCR Output Optoisolators Feature Summary

Integrated zero-crossing detection circuitry for reduced noise generation
High isolation voltage rating for safe operation in mains-powered systems
Triac output stage optimized for direct AC load control

Triac, SCR Output Optoisolators Applications

Solid-state relay modules for industrial automation
AC motor speed control circuits
Lighting dimmer switches and controllers

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity due to obsolete status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check datasheet revisions for any historical parameter updates before finalizing design integration.

Triac, SCR Output Optoisolators Selection Notes

Select this component when high isolation voltage and zero-crossing functionality are required for AC loads. Ensure the 600V off-state voltage rating exceeds the peak line voltage. Verify that the 3.5mA hold current aligns with the specific load characteristics to prevent unintended latching or premature turn-off.

Triac, SCR Output Optoisolators Part Context

Part of Sharp's optoisolator portfolio, the S21MT2 serves as a bridge between low-voltage control logic and high-voltage AC power stages. It belongs to the category of triac output optocouplers, distinct from phototransistor or SCR variants within the same manufacturer lineup.
