The PS8501, PS8501L1, PS8501L2 and PS8501L3 are 8-pin High-Speed photocouplers containing a GaAIAs LED on input side and a PN photodiode and a High-Speed amplifier transistor on output side on one chip. The PS8501 is in a plastic DIP (Dual In-line Package) with 8 mm creepage distance product. The PS8501L1 is lead bending type for long creepage distance. The PS8501L2 is lead bending type for long creepage distance (Gull-wing) for surface mount. The PS8501L3 is lead bending type (Gull-wing) for surface mounting.
