The PS2707-1, PS2707-2, PS2707-4 are optically coupled isolators containing GaAs light emitting diodes and an NPN silicon phototransistor. They are suitable for high density applications and feature AC input response, high collector to emitter voltage, high isolation voltage, small and thin package, and high-speed switching.
The PS2707-1, PS2707-2, and PS2707-4 are optically coupled isolators that combine a GaAs LED with an NPN silicon phototransistor. Each device is mounted in a plastic SOP package that provides shielding against ambient light and supports high‑density board layouts.
Key features include AC input response, a collector‑to‑emitter voltage rating of 120 V, isolation voltage up to 3750 Vrms, and fast switching times. The series is suited for hybrid ICs, telephone/FAX equipment, FA/OA equipment, and programmable logic controllers. Ordering numbers differentiate package pin counts and optional safety approvals (UL, VDE).
