This datasheet describes the PS8502, PS8502L1, PS8502L2 and PS8502L3 series of NEC Electronics 8-pin high speed photocouplers. The series has a 8mm long creepage distance, high common mode transient suppression, high supply voltage, high response speed and high isolation voltage.
The NEC PS8502 series includes four 8‑pin high‑speed photocouplers (PS8502, PS8502L1, PS8502L2, PS8502L3) that combine a GaAlAs LED, a PN photodiode and a high‑speed amplifier transistor on a single chip. Variants differ in lead style and mounting type, offering long creepage distances up to 8 mm.
The document provides mechanical dimensions, electrical ratings, safety approvals, ordering information and usage cautions for designers integrating these components into measurement, control, modem or inverter applications.
