Toshiba TLP651 Photocoupler Datasheet
The TLP651 is a GaAs infrared photocoupler that combines a high‑output LED with a fast detector in a single 8‑lead DIP package. It is designed for digital logic ground isolation, line‑receiver functions, and analog signal isolation in microprocessor and switching‑power applications.
Key specifications include a minimum isolation voltage of 5000 V, typical propagation delay of 0.3 µs, forward current rating of 25 mA, and an output current capability of 8 mA. The device is UL‑1577 and BS EN60065 certified and is intended for general electronics use while prohibiting high‑risk applications such as aerospace or medical equipment.
