MOC3082SVM

Triac, SCR Output Optoisolators Overview

The MOC3082SVM is a single-channel Triac output optocoupler featuring a surface mount DIP-6 package. It integrates a gallium arsenide infrared emitting diode with a monolithic silicon detector to perform zero voltage crossing triac driver functions. The device provides high isolation, rated at 5300 Vrms maximum insulation voltage and 4170 Vrms in some specifications, suitable for interfacing logic systems with AC power lines. Key electrical parameters include a maximum forward current of 60 mA, a typical input trigger current of 10 mA, and a peak off-state voltage of 800 V.

Triac, SCR Output Optoisolators Feature Summary

• Integrates zero voltage crossing circuitry to minimize electromagnetic interference during switching
• Provides galvanic isolation between low-voltage control logic and high-voltage AC loads
• Utilizes a surface mount MDIP-6 package for compact PCB integration
• Designed for reliable operation in industrial and consumer appliance environments

Triac, SCR Output Optoisolators Applications

• Solid-state relays for AC load switching
• Industrial motor and solenoid controls
• Consumer appliance power management interfaces
• Valve control systems requiring isolated triggering

Triac, SCR Output Optoisolators Procurement Notes

Verify the suffix 'V' indicates compliance with VDE 0884 testing requirements as specified by Fairchild Semiconductor. Confirm that the manufacturer designation aligns with onsemi, which acquired Fairchild's semiconductor business. Ensure the surface mount package type matches the required PCB footprint. Cross-reference the specific batch markings against official datasheets to confirm authenticity and performance characteristics.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce noise in AC power applications. The 800 V peak off-state voltage supports standard 240 Vac line voltages. The surface mount configuration is preferred for automated assembly processes. Consider the 10 mA nominal trigger current for compatibility with standard logic outputs. Verify thermal management requirements for the surface mount package in enclosed designs.

Triac, SCR Output Optoisolators Part Context

This device belongs to the GlobalOptoisolator™ family of zero-crossing triac drivers. It is functionally similar to the through-hole MOC3082S but utilizes a surface mount form factor. The series includes variants like MOC3081 and MOC3083 with different trigger sensitivities. These components are widely used in isolation applications where timing precision and noise reduction are critical for AC power control.

Triac, SCR Output Optoisolators Replacement Considerations

The MOC3082SM is a direct equivalent from onsemi with identical functional specifications. The MOC3082S serves as a through-hole alternative with comparable electrical ratings. Ensure pinout compatibility when substituting surface mount packages with DIP versions. Verify that any replacement maintains the zero-crossing feature and adequate isolation voltage for the specific application safety standards.
