MOC3062

Triac, SCR Output Optoisolators Overview

The MOC3062 is a zero-crossing triac output optoisolator manufactured by Isocom Components. It features an internal phototriac with a peak repetitive off-state voltage of 600V and an isolation voltage rating of 5300Vrms. The device utilizes a gallium arsenide infrared LED for input coupling, supporting a maximum forward current of 50mA and a typical forward voltage of 1.2V. Designed for robust AC switching applications, it provides high static dv/dt immunity of 1000V/µs to prevent false triggering. The component is available in a standard 6-pin DIP package, ensuring reliable electrical isolation between control circuits and high-voltage loads.

Triac, SCR Output Optoisolators Feature Summary

• Zero-crossing detection capability minimizes electromagnetic interference during AC load switching
• High isolation voltage rating ensures safe separation between low-voltage control and high-voltage power circuits
• Integrated phototriac output eliminates the need for external snubber networks in many applications

Triac, SCR Output Optoisolators Applications

• Solid state relay driver circuits
• AC motor speed control systems
• Lighting dimmer modules

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix code on the component marking to confirm the exact package variant, as Isocom offers both through-hole DIP and surface-mount SMD configurations within the MOC306x series. Ensure that the procurement documentation explicitly references the manufacturer's official datasheet specifications rather than generic distributor descriptions. Cross-reference the part number against the latest Isocom Components product list to confirm availability and compliance with current manufacturing standards before finalizing orders.

Triac, SCR Output Optoisolators Selection Notes

Select the MOC3062 when zero-crossing operation is required to reduce electrical noise and extend the lifespan of resistive or incandescent loads. This component is suitable for driving triacs or SCRs in AC power control applications where galvanic isolation is critical. Designers must ensure the load current does not exceed the internal phototriac's capabilities without external buffering. Consider thermal management requirements if operating near the upper limit of the specified temperature range.

Triac, SCR Output Optoisolators Part Context

The MOC3062 belongs to the MOC306x family of zero-crossing triac output optoisolators from Isocom Components. This series is engineered for general-purpose AC power switching, offering a balance of high isolation performance and simple interface requirements. The family shares common architectural features, including the use of an infrared LED coupled to a silicon phototriac, designed to meet international safety standards for industrial and consumer electronics.

Triac, SCR Output Optoisolators Replacement Considerations

Compatible alternatives include the MOC3061, MOC3063, and MOC3082, which share similar zero-crossing characteristics and pinout configurations. Verify that substitute components match the required peak off-state voltage and isolation ratings for the specific application environment.
