TLP114A is a photocoupler produced by Toshiba Corporation. It has the characteristics of high output power, low power consumption, high isolation voltage and high speed. It is suitable for digital logic isolation, line reception, power control, feedback control, switching power supply, transistor inverter and other applications.
The TLP114A is a miniature GaAs infrared photocoupler designed for surface‑mount assembly. It combines a high‑output power LED with a fast photodiode‑transistor detector, offering digital logic isolation, line‑receiver, and power‑supply feedback functions.
Key specifications include a minimum isolation voltage of 3750 Vrms, forward current up to 20 mA, and propagation delay times of 0.8 µs. The document also outlines absolute maximum ratings, switching characteristics, and usage restrictions for reliable integration in electronic designs.
