MOC3020SMT&R

Triac, SCR Output Optoisolators Overview

The MOC3020SMT&R is a surface-mount optocoupler manufactured by Isocom Components 2004 LTD. It integrates a gallium arsenide infrared emitting diode with a light-activated silicon bilateral triac. The device provides 4170Vrms isolation voltage and operates in non-zero crossing mode for random phase control applications. It features a peak repetitive off-state voltage of 400V and supports a peak surge current of 1A. The component is housed in a 6-pin surface mount package and is rated for operation between -40°C and 100°C.

Triac, SCR Output Optoisolators Feature Summary

• Integrates an infrared LED with a light-activated silicon bilateral triac for signal isolation.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'R' against official manufacturer documentation to confirm reel packaging specifications. Ensure the selected variant matches the required 4170Vrms isolation rating and non-zero crossing behavior. Cross-reference the 6-SMD package dimensions with PCB layout requirements before finalizing procurement decisions.

Triac, SCR Output Optoisolators Selection Notes

Select this component when non-zero crossing triac drive is required for AC load control. Confirm that the 400V peak off-state voltage meets the circuit's maximum line voltage requirements. Verify compatibility with the 6-pin surface mount footprint and ensure the operating temperature range suits the intended environment.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC3020 series of optically coupled isolators. It is distinct from zero-crossing variants within the same family, offering random phase firing capabilities instead. The SMT&R designation indicates a surface mount configuration supplied in a tape and reel format for automated assembly processes.
