It provides 3750Vrms isolation between input and output, making it suitable for signal isolation in industrial controls, PLC I/O modules, motor drive feedback, and isolated power-supply monitoring where galvanic isolation is required between low-voltage control logic and higher-voltage power stages. The current transfer ratio spans 50% minimum to 400% maximum, both specified at 5mA forward current. That 8:1 spread means the design must accommodate the weakest unit at end-of-life and temperature extremes. For a logic-level output, size the input resistor so the minimum CTR still saturates the output transistor with the chosen collector load. The 300mV Vce saturation maximum keeps the output swing within a logic low threshold for 3.3V and 5V rails. ## Output voltage and current ratings The output transistor is rated for 120V maximum collector-emitter voltage and 30mA continuous output current per channel. This covers 24V industrial logic rails, 48V telecom supplies, and low-side switching up to 120V DC. The 30mA limit is per-channel — if driving an LED or relay coil directly, confirm the load current stays under that ceiling including inrush. ## Temperature range and switching speed Operating temperature spans -55°C to 100°C, covering industrial, outdoor telecom cabinet, and some automotive cabin environments. The 10µs typical rise and fall times suit slow digital signals, status feedback, and DC-level isolation — not high-speed data or PWM above a few kHz. For faster switching, consider a logic-output optocoupler or digital isolator.","metaTitle":"PS2703-1-F3-A NEPOC Optocoupler, 3750Vrms, 1-Ch DC Input","metaDescription":"Renesas NEPOC PS2703-1-F3-A single-channel transistor output optocoupler. 3750Vrms isolation, 50-400% CTR at 5mA, -55°C to 100°C.
