The TLP521-4X is a four-channel optically coupled isolator with an infrared LED and NPN phototransistor, housed in a 16-pin dual in-line plastic package. It provides 5000 Vrms isolation voltage, operates from -40°C to 105°C, and features a current transfer ratio ranging from 50% to 600% at 5 mA forward current and 5 V collector-emitter voltage. The device meets UL and VDE safety approvals with UL File E91231 and VDE Certificate No. 40028086, is RoHS compliant, and employs surface-mount or through-hole packaging variants. Collector-emitter saturation voltage is specified at 0.2 V max under 20 mA forward current and 1 mA collector current, and the cut-off frequency is 80 kHz with 100 Ω load resistance. Output rise and fall times are 4 µs and 18 µs respectively at 5 V supply and 2 mA collector current.
