It provides 5000Vrms galvanic isolation between input and output, making it suitable for breaking ground loops in industrial control interfaces, PLC digital inputs, and motor-drive feedback circuits. Each channel uses a DC-input LED (1.2V typical forward voltage) driving a phototransistor rated for up to 30V output and 30mA continuous output current. The minimum current transfer ratio of 100% at 5mA input ensures the output can saturate a logic-level load without excessive LED drive current. ## Switching speed and temperature range for industrial environments Typical turn-on and turn-off times are both 2.4µs, adequate for slow optocoupler applications like status feedback and relay drivers. The operating temperature range of -55°C to 100°C covers industrial and outdoor telecom enclosures. The 400mV maximum Vce saturation at the output keeps power dissipation low when driving a logic input, reducing self-heating inside the DIP package. ## Active production and sourcing posture Sourced to order against BOM quantities — confirm lead time and pricing with an RFQ.","metaTitle":"MCT62 Optoisolator – onsemi 5000Vrms 2-Ch Transistor Output","metaDescription":"onsemi MCT62 dual-channel transistor output optocoupler, 5000Vrms isolation, 100% min CTR at 5mA, -55°C to 100°C.
