MOC3162TM

Triac, SCR Output Optoisolators Overview

The MOC3162TM is a single-channel Triac output optocoupler designed for zero-crossing switching applications. It integrates an infrared LED with a photosensitive triac driver and a triac in a compact 6-DIP package. The device provides electrical isolation between control circuits and high-voltage AC loads, featuring a minimum off-state peak voltage of 600V and a maximum insulation voltage of 7500V. It operates within a temperature range of -40°C to 85°C.

Triac, SCR Output Optoisolators Feature Summary

• Integrates zero-crossing detection circuitry to minimize electromagnetic interference during switching events
• Provides high-voltage isolation capability suitable for connecting low-voltage logic to mains-powered systems
• Utilizes a through-hole DIP-6 package for reliable mounting in industrial and consumer electronics designs

Triac, SCR Output Optoisolators Applications

• Solid-state relay drivers for AC load control
• Motor speed control circuits using phase-angle or zero-crossing techniques
• High-voltage switching interfaces in industrial automation equipment

Triac, SCR Output Optoisolators Procurement Notes

Verify the manufacturer marking matches Fairchild Semiconductor specifications. Confirm the package type is 6-DIP and check for any suffix variations that may indicate different tape-and-reel packaging options. Ensure compliance with RoHS standards if required by your application environment.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce noise in AC power control applications. Consider the 600V blocking voltage rating for standard line-voltage applications. Evaluate the thermal performance requirements against the specified operating temperature range of -40°C to 85°C.

Triac, SCR Output Optoisolators Part Context

This part belongs to the family of Triac output optocouplers designed for AC power switching. It serves as an interface between microcontrollers or logic gates and high-power AC devices. The zero-crossing feature distinguishes it from random-phase variants, making it suitable for applications where switching noise must be minimized.

Triac, SCR Output Optoisolators Replacement Considerations

The MOC3162FM is a documented substitute variant offering similar functionality with a 7500V isolation rating. Verify pinout compatibility and ensure the replacement meets the same 600V off-state voltage requirement for your specific circuit design.
