H11J3XSMT&R

Triac, SCR Output Optoisolators Overview

The H11J3XSMT&R is a surface-mount optocoupler from Isocom Components, featuring a single channel with a random-phase triac output. It provides an isolation voltage of 5300Vrms and supports a peak repetitive off-state voltage of 250V. The device utilizes a 6-pin Surface Mount DIP package for non-zero crossing applications.

Triac, SCR Output Optoisolators Feature Summary

• Integrates a random-phase triac output stage for AC load control
• Provides high electrical isolation via 5300Vrms dielectric barrier
• Designed for non-zero crossing switching operations

Triac, SCR Output Optoisolators Applications

• AC motor speed control circuits
• Solid state relay (SSR) driver stages
• Lighting dimmer module interfaces

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SMT&R' confirms the tape-and-reel packaging format required for automated assembly lines. Confirm that the 250V rating aligns with the target circuit's peak voltage requirements to ensure adequate safety margins during operation.

Triac, SCR Output Optoisolators Selection Notes

Select this component when non-zero crossing triac triggering is necessary rather than zero-crossing variants. Ensure the PCB layout accommodates the 6-pin SMD footprint and maintains creepage distances suitable for the 5300Vrms isolation rating.

Triac, SCR Output Optoisolators Part Context

This part belongs to the H11J3 series of optoisolators designed for industrial AC power switching. It serves as a bridge between low-voltage logic controllers and higher-voltage AC loads, offering galvanic separation to protect sensitive input electronics from noise and transients.

Triac, SCR Output Optoisolators Replacement Considerations

Check datasheets for compatible equivalents such as the H11J3XSM variant, noting potential differences in packaging or reel specifications while maintaining identical electrical performance characteristics.
