The PS2501L-1-F3-A KK is a high-isolation optocoupler manufactured by CEL (California Eastern Laboratories, a subsidiary of Renesas Electronics). It features a GaAs LED input and a phototransistor output, designed for electrical isolation between circuits. The 'F3' indicates a specific lead forming option, 'A' denotes a particular CTR (Current Transfer Ratio) rank, and 'KK' likely signifies an internal manufacturing code or quality control specification.

Applications
