MOC3052SVM

Triac, SCR Output Optoisolators Overview

The MOC3052SVM is a single-channel optoisolator featuring a Triac output, manufactured by onsemi. It provides electrical isolation of 4170Vrms between input and output circuits. The device supports a maximum forward current of 60 mA and has a typical LED forward voltage of 1.18 V. It operates within a temperature range of -40°C to 85°C. Key electrical parameters include a peak repetitive off-state voltage of 600 V, a minimum static dV/dt of 1 kV/µs, and a typical holding current of 220 µA. The component is housed in a 6-SMD鸥翼 (gull-wing) package.

Triac, SCR Output Optoisolators Feature Summary

• Provides galvanic isolation between low-voltage logic circuits and high-voltage AC loads using an internal Triac output structure.
• Features enhanced static dV/dt capability to prevent false triggering in noisy environments or when driving inductive loads.
• Designed for random phase firing control, allowing triac triggering at any point in the AC line cycle rather than zero-crossing only.

Triac, SCR Output Optoisolators Applications

• Isolation interface for microcontrollers controlling AC mains-powered devices
• Solid-state relay driver circuits for industrial automation
• Motor speed control systems requiring random phase firing

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SVM' corresponds to the 6-SMD gull-wing package configuration. Confirm RoHS compliance status as per the latest manufacturer declaration. Ensure the ordering part number matches the required lead time specifications provided by authorized distributors. Cross-reference UL and VDE certification marks if safety isolation is critical for the end application.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase control is required instead of zero-crossing switching. Verify that the 600 V blocking voltage meets the peak line voltage requirements of the target AC system. Ensure the PCB footprint accommodates the 6-SMD gull-wing package dimensions. Check that the 1 kV/µs dV/dt rating is sufficient for the inductance levels present in the load circuit to avoid unintended turn-on.

Triac, SCR Output Optoisolators Part Context

This device belongs to the MOC305x series of random-phase Triac driver optocouplers from onsemi. It shares functional similarities with other members like the MOC3051 and MOC3053 but differs in specific electrical ratings and packaging options. The 'SVM' suffix specifically denotes the surface-mount variant with gull-wing leads, distinguishing it from through-hole DIP versions.
