5000Vrms isolation in a 4-SMD gull wing package
The Renesas PS2565L-1Y-V-A is a single-channel optocoupler in a 4-SMD gull wing package, designed for signal isolation across a 5000Vrms barrier. It accepts both AC and DC input on the LED side and provides a phototransistor output, making it a straightforward fit for logic-level isolation, PLC digital inputs, or motor-drive feedback paths where galvanic separation is required. The 80% to 400% current transfer ratio range at 5mA forward current gives the designer headroom to guarantee logic-high detection across temperature and LED aging.
Temperature range and switching speed
The 3µs rise and 5µs fall times (typical) keep up with 100 kbps data rates, adequate for status feedback, relay drivers, or isolated I/O. Vce saturation is specified at 300mV max, so the output transistor pulls low cleanly when driving a downstream logic input or a small relay coil.
