The TCLD1000 is a low power optocoupler with a 4-lead SOP-4L package. The device features a small package, low power consumption, high common mode rejection and low coupling capacitance. The device is widely used in switch mode power supplies, line receivers, computer peripheral interfaces and microprocessor system interfaces.
The TCL1000 is a low‑profile optocoupler with a Darlington phototransistor output, designed for use in switch‑mode power supplies, line receivers and computer peripheral interfaces. It offers extra‑low coupling capacitance (typical 0.2 pF), high common‑mode rejection and robust safety ratings up to 5000 V RMS isolation.
The device is supplied in a 4‑lead SOP‑4L (SOG6L) package with a thickness of 0.75 mm and a creepage distance greater than 8 mm. Electrical characteristics include a collector‑emitter voltage rating of 35 V, a forward current of up to 60 mA, and a current transfer ratio (CTR) of 600‑800 %. The datasheet also provides detailed temperature derating curves and mechanical drawings for PCB layout.
