The TCLT10.. Series optocouplers integrate a gallium‑arsenide infrared LED with a phototransistor in a 4‑lead SOP‑4L package. They are intended for use in switch‑mode power supplies, computer peripheral interfaces, and microprocessor system interfaces.
Key features include a high isolation voltage of 5000 VRMS, low coupling capacitance, and a wide CTR range (50‑600 %). The device operates from –40 °C to +100 °C, with typical forward voltage around 1.6 V and power dissipation up to 100 mW. Switching times are in the low‑microsecond range, making the series suitable for high‑speed isolation applications.
