Renesas Electronics Corporation PS2561DL-1Y-H-A

The PS2561DL-1 is a DIP photocopler with a GaAs LED and NPN silicon phototransistor, housed in a surface-mount gull-wing package. It features an operating ambient temperature of 110 °C, an isolation voltage of 5000 Vr.m.s., a collector-emitter voltage rating of 80 V, a typical current transfer ratio of 160 %, and switching times of 3 μs rise and 5 μs fall. The device has a creepage and air distance of 8 mm, supports reinforced insulation per UL1577, CSA CAN/CSA-C22.2 No. 62368-1, BSI EN 62368-1, SEMKO, NEMKO, FIMKO, DEMKO, and CQC standards, and is Pb-free. The part number PS2561DL-1Y-H-A is an orderable variant of this series with additional packaging or finish codes, but the core specifications remain consistent with the PS2561DL-1 series as documented.
