Product Description

Product Overview

The PS2501-1, -4 and PS2501L-1, -4 are high-isolation voltage single transistor type optically coupled isolators. They integrate a GaAs light-emitting diode with an NPN silicon phototransistor. The PS2501-1, -4 are available in a plastic DIP, while the PS2501L-1, -4 feature lead bending for surface mount applications. These devices offer high-speed switching and are suitable for power supplies, telephone/FAX, FA/OA equipment, and programmable logic controllers.
