The PS2800C-1 and PS2801C-4 are optically coupled isolators containing a GaAs light emitting diode and an NPN silicon phototransistor in a plastic SSOP for high density applications to realize an excellent cost performance. This package has shield effect to cut off ambient light.
The NEC PS2801C-1 and PS2801C-4 are optically coupled isolators that combine a GaAs LED with an NPN silicon phototransistor in a thin 4‑ or 16‑pin SSOP package. They provide high isolation voltage (2.5 kV rms) and are suitable for high‑density applications such as programmable logic controllers and measuring instruments.
The document includes electrical characteristics, absolute maximum ratings, ordering information, package dimensions, and safety/disposal guidelines. It also lists typical performance curves and normalized current‑transfer ratios for design reference.
