The TOSHIBA TLP2530 and TLP2531 dual photocouplers consist of a pair of GaAℓAs light emitting diode and integrated photodetector. This unit is 8−lead DIP. 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 TLP2530 and TLP2531 are dual GaAs infrared photocouplers packaged in an 8‑lead DIP. They provide digital logic isolation for power‑supply control, switching power supplies, and transistor inverters, with separate photodiode bias and output transistor connections for high speed operation.
Key specifications include a minimum isolation voltage of 2500 Vrms, typical propagation delays of 0.3 µs, and recommended supply voltage up to 12 V. The devices operate from –55 °C to 100 °C and are UL1577 certified. Detailed absolute‑maximum ratings, electrical characteristics, and switching performance are provided for design reference.
