It provides 2500Vrms galvanic isolation between a DC input LED and a Darlington phototransistor output, delivering a current transfer ratio (CTR) of 400% to 4500% at a forward current of 1mA. This high gain means a low LED drive current can switch a much larger output current — up to 60mA per channel — making it suitable for interfacing low-voltage logic to higher-voltage loads or for driving relays, solenoids, and PLC inputs in industrial control, motor drives, and power-supply feedback loops. ## 350V output — what it buys you The collector-emitter voltage rating of 350V on the Darlington output lets this part switch loads on a high-voltage rail directly, without an external transistor stage. Common applications include driving a 24V or 48V industrial load from a 3.3V or 5V microcontroller pin, or providing isolated feedback in a 250V DC-link power supply. The 1V Vce saturation at 60mA means the output transistor drops about a volt when on — budget that drop in your load voltage calculation. ## Speed and timing for the signal path Rise and fall times are 20µs and 5µs typical, respectively. That puts this part in the low-speed optocoupler class — fine for DC-level sensing, relay coil drive, or 50/60 Hz mains zero-cross detection, but not for high-speed data or PWM above a few kilohertz. If your application needs faster switching, a phototransistor-output optocoupler (like the PS2801C-4-V-A) with 5µs rise/7µs fall times may be a better fit. ## Package and temperature range Housed in a 4-SOIC package (4.40mm width, supplier device package 4-SSOP), this part is a surface-mount component suited for automated assembly. Storage temperature exceeds the operating range, so the part can survive handling in a wider thermal envelope.","metaTitle":"PS2833-1-F3-A NEPOC Darlington Optocoupler, 2500Vrms, 4-SOIC","metaDescription":"PS2833-1-F3-A NEPOC Darlington optocoupler, 1-channel, 2500Vrms isolation, 400%-4500% CTR at 1mA, 350V output, -55°C to 100°C.

The trade-off is slower switching speed — 20µs rise time versus 5µs for a phototransistor.
