● Current transfer ratio(CTR: 50~600% at IF =5mA, VCE = 5V)

● High isolation voltage between input and output (Viso =5000Vrms )

● Collector - emitter breakdown voltage BVCEO ≥ 80V

● Operating Temperature: -55℃~110℃

● Environmentally friendly products, compliant with CQC, UL, and VDE requirements

●  It is widely used in the feedback control loop of switching power supply and the isolation between the main circuit and the control circuit, ensuring the stability of the output voltage and quickly transmitting the fault signal to trigger the protection mechanism in the case of overload or short circuit.

● In applications such as PLCs (Programmable Logic Controllers), motor drives, and sensor interfaces, it is used for signal isolation to prevent high-voltage noise from interfering with low-voltage control logic.

● For signal isolation in serial communication interfaces (e.g., RS-232,) to improve anti-interference capability.

● Consumer electronics: household appliances, smart home devices (smart lighting, smart sockets), computers and peripherals (printers, monitors), etc.

● Lighting control: AC transistor optocoupler is suitable for dimming control, smart switching, and wireless control, supporting AC input.
