The PS2805C-1 and PS2805C-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 PS2805C-1 and PS2805C-4 are optically coupled isolators that combine a GaAs light‑emitting diode with an NPN silicon phototransistor in a compact SSOP package. They offer high isolation voltage and a shielded package to block ambient light, making them suitable for high‑density applications.
Key specifications include a 2 500 Vrms isolation voltage, 80 V collector‑to‑emitter rating, CTR ranging from 50 % to 400 %, and operation from –55 °C to +100 °C. The datasheet also lists package dimensions, marking conventions, and various ordering options such as tape and reel formats.
