Product Description
Product Overview
The PS2501-1, -4 and PS2501L-1, -4 are single transistor type optically coupled isolators. They integrate a GaAs light emitting diode with an NPN silicon phototransistor, offering high isolation voltage (5000 Vr.m.s.) and high-speed switching capabilities (3 s TYP. rise time, 5 s TYP. fall time). The PS2501-1, -4 are available in a plastic DIP package, while the PS2501L-1, -4 feature lead bending for surface mount applications. These devices are suitable for power supplies, telephone/FAX, FA/OA equipment, and programmable logic controllers.
