The 4N25S is a 6-pin surface-mount photo coupler featuring a bipolar transistor output and 2500 Vrms isolation. It is packaged in a surface-mount configuration with lead bends for PCB mounting, and supports a collector-emitter voltage of 30 V, collector current of 100 mA, and total power dissipation of 250 mW. It meets UL, TUV, CSA, FIMKO, NEMKO, DEMKO, SEMKO, and VDE safety standards. The current transfer ratio is a minimum of 20% at 10 mA forward current and 10 V collector-emitter voltage. Rise and fall times are typified at 3 µs with a 100 Ω load. Operating temperature ranges from -55 °C to +100 °C.
