Your 240VAC circuit needs a clean isolation barrier between control and power side. The MOC3020/MOC3021 gives you that. 7.5kVAC peak minimum isolation voltage. Low-degradation IR emitting diode means it holds up over time, not just on day one. UL recognised (file #E90700). Recommended for 240VAC RMS applications. If your board design needs a dependable optocoupler that won't drift after months of thermal cycling, this is the part
