| Datasheet | Download Datasheet |
The Coto C774S is an MOSFET relay with a 1 Form A 1 Form B output rated 400 V (AC peak or DC) and 80 mA (NO), 60 mA (NC) continuous (0.4 A peak) for AC/DC loads, in a SOP8 surface mount package.
Its on resistance is 30 ohm (NO), 50 ohm (NC) maximum (24 ohm (NO), 30 ohm (NC) typical). Output capacitance is 115 pF (NO), 165 pF (NC) typical. It turns on in 2.0 ms and off in 1.0 ms. The LED input operates at 3.0 mA maximum (50 mA absolute maximum forward current).
Input to output isolation is 1500 Vrms. Off-state leakage current is 1 µA (NO), 10 µA (NC) maximum. It operates from -40...+85 °C.
