It accepts both AC and DC input on the LED side, which simplifies polarity-insensitive designs — handy when the input comes from a bipolar sensor or a relay contact that might swing either way. The transistor output is rated for 80V and 30mA continuous, enough to drive a logic input, a small relay coil, or a status LED on the secondary side. ## CTR spread: 50% to 400% at 5mA forward current The current transfer ratio spans 50% minimum to 400% maximum, tested at 5mA LED current. ## Switching speed — this is not a high-speed isolator Rise time is 5µs typical, fall time 7µs typical. Turn-on is 10µs, turn-off 7µs. ## Temperature range: -55°C to 100°C Rated for -55°C to 100°C operating. ## Package and mounting Comes in a 4-SOIC (0.173\", 4.40mm width) package, also called 4-SSOP in the supplier device package field. Surface-mount only. The LED anode and cathode are on one side, the transistor collector and emitter on the other — orientation is obvious from the package marking, so a field swap with a hot-air station is doable if you have the kit. No exposed pad, no thermal via stitching needed.","metaTitle":"PS2805C-1-F3-A Optocoupler, 2500Vrms, NEPOC Series","metaDescription":"PS2805C-1-F3-A single-channel transistor-output optocoupler, 2500Vrms isolation, 50-400% CTR, -55 to 100°C.
