This document describes the features of the TLP2530 and TLP2531 dual photocouplers. These photocouplers have high-speed transmission and isolation characteristics, making them suitable for applications such as digital logic isolation, line reception, power supply control, and switching power supplies.
The Toshiba TLP2530 and TLP2531 are dual GaAs photocouplers that combine a light‑emitting diode with an integrated photodetector in an 8‑lead DIP package. They provide TTL‑compatible logic isolation with high speed and a minimum isolation voltage of 2500 Vrms.
The datasheet lists maximum ratings, recommended operating conditions, electrical and switching characteristics, as well as handling and safety restrictions for use in general electronics applications.
