With a current transfer ratio (CTR) guaranteed between 50% and 400% at 5 mA forward current, it is designed for logic-level interfacing, PLC I/O modules, and isolated sensor feedback in industrial and telecom equipment. ## CTR spread and drive margin The 50% to 400% CTR range at 5 mA is the headline design parameter. A minimum CTR of 50% means the output transistor will saturate with as little as 5 mA LED drive, but the 8:1 spread means the actual gain varies widely across units. For a 5 V logic-level shift, the typical forward voltage is 1.2 V, and the output can sink up to 30 mA per channel at a maximum Vce saturation of 300 mV. The 80 V output rating gives headroom for 24 V or 48 V industrial buses. Rise time is 5 µs, fall time 7 µs, turn-on 10 µs, turn-off 7 µs. ## Package and footprint The part is offered in a 16-SOIC (0.173\", 4.40 mm width) package, with the supplier device package listed as 16-SSOP. The 4-channel layout consolidates four optocouplers into one IC, saving board area versus four single-channel parts in SOIC-4 or DIP-4 packages.","metaTitle":"PS2801C-4-F3-A Optocoupler, 4-Ch, 2500Vrms, 16-SOIC","metaDescription":"PS2801C-4-F3-A 4-channel transistor output optocoupler with 2500Vrms isolation, 50-400% CTR at 5mA, -55°C to 100°C.

This wide spread means the design must tolerate the full range; for critical applications, consider binning or a tighter CTR grade if available."},{"question":"Can PS2801C-4-F3-A be used for 5V logic level shifting?","answer":"Yes. With a minimum CTR of 50% at 5 mA, a 5 V logic signal driving the LED through a current-limiting resistor (e.g., 680 Ω for 5 mA) will reliably saturate the output transistor, pulling the collector to below 300 mV. The 80 V output rating also handles 24 V or 48 V logic levels on the output side."},{"question":"What is the equivalent or replacement for PS2801C-4-F3-A?","answer":"The Renesas PS2801C-4-V-A is a functionally identical variant using the same die. The only difference is packaging: the -F3-A ships in Tape & Reel, while the -V-A ships in strip packaging.
