H11J3X

Triac, SCR Output Optoisolators Overview

The H11J3X is a Triac output optoisolator manufactured by Isocom Components 2004 LTD. It features a random phase TRIAC output capable of switching AC loads in both directions. The device provides electrical isolation with a rated isolation voltage of 5300Vrms. It is housed in a standard 6-DIP package, suitable for through-hole mounting on printed circuit boards. The input side utilizes an infrared emitting diode driven by DC signals to control the triac output stage.

Triac, SCR Output Optoisolators Feature Summary

• Random phase TRIAC output enables triggering at any point in the AC cycle
• High isolation voltage rating ensures robust signal separation between input and output circuits
• Integrated base resistor simplifies interface design for AC load switching applications

Triac, SCR Output Optoisolators Applications

• Solid state relays for AC power control
• Motor speed controllers using AC induction motors
• Lighting dimmer circuits for resistive or inductive loads

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'X' against the manufacturer's current datasheet to confirm pinout compatibility and insulation class ratings. Ensure the procurement source provides official documentation confirming the 5300Vrms isolation specification. Cross-reference the package dimensions with your PCB footprint requirements before ordering.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triggering is required rather than zero-crossing detection. The 5300Vrms isolation rating suits high-noise industrial environments. Confirm that the peak repetitive off-state voltage rating meets the maximum line voltage of the application. The DIP-6 package facilitates easy prototyping and manual assembly.

Triac, SCR Output Optoisolators Part Context

This part belongs to the H11J series of TRIAC output optocouplers from Isocom Components 2004 LTD. These devices are designed for general-purpose AC switching where precise timing relative to the AC waveform zero-crossing is not critical. The series offers a balance of isolation performance and switching capability for consumer and industrial electronics.

Triac, SCR Output Optoisolators Replacement Considerations

Check for direct replacements within the same family, such as other variants in the H11J series. Verify pin-for-pin compatibility with alternative manufacturers offering similar random phase TRIAC optocouplers. Ensure replacement parts maintain the same isolation voltage and package type.
