The PS2815-1 and PS2815-4 are optically coupled isolators containing GaAs light emitting diodes and an NPN silicon phototransistor in a plastic SSOP for high density applications. The product features AC input response, high current transfer ratio, high isolation voltage, and small and thin package.
The NEC PS2815-1 and PS2815-4 are GaAs photo‑couplers that combine an infrared LED and an NPN phototransistor in a 4‑ or 16‑pin SSOP package. They are intended for high‑density applications such as programmable logic controllers, modems and fax equipment.
The document provides electrical characteristics, absolute maximum ratings, package dimensions, ordering information and safety approvals (UL and DIN EN60747‑5‑2). It also includes typical performance graphs and handling instructions for the GaAs material.
