TLP2530,TLP2531 is a dual photocoupler from TOSHIBA, consisting of a pair of GaAℓAs light emitting diodes and integrated photodetectors. This unit is an 8-lead DIP package. Separate connection for the photodiode bias and output transistor collectors improve the speed up to a hundred times that of a conventional phototransistor coupler by reducing the base-collector capacitance.
The Toshiba TLP2530 and TLP2531 are dual GaAs photocouplers offered in an 8‑lead DIP package. They provide digital logic isolation for line receivers, power‑supply control, and switching‑power applications, with separate photodiode bias and output transistor connections for high speed.
