MOC3043SR2VM

Triac, SCR Output Optoisolators Overview

The MOC3043SR2VM is a single-channel triac output optocoupler featuring an integrated zero-crossing detection circuit. It consists of an aluminum gallium arsenide infrared emitting diode optically coupled to a monolithic silicon detector that functions as a zero voltage crossing bilateral triac driver. The device operates within a temperature range of -40°C to +85°C and provides an isolation voltage of 5250 Vrms. Key electrical parameters include a forward current of 60 mA, a forward voltage of 1.25 V, and a power dissipation of 250 mW. The off-state output voltage (VDRM) is rated at 400 V, with a maximum trigger current of 5 mA.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'VM' against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compatibility with surface mount assembly processes if utilizing the SMD variant. Cross-reference RoHS compliance status directly with official documentation prior to procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce electrical noise in AC control applications. The 400 V off-state rating suits lower voltage AC lines. Consider the 6-pin SMD package for space-constrained designs requiring surface mount technology integration.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC304XM series of 6-pin DIP zero-cross optoisolators designed for triac driver outputs. It shares functional similarities with other devices in the family but differs in packaging and specific ordering suffixes. The series simplifies logic control of AC power by ensuring triacs are triggered only near zero voltage crossings.
