PC12311NSZ0F

Overview

The PC12311NSZ0F is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features a 5000Vrms isolation voltage and operates within a temperature range of -30°C to +100°C. The device utilizes an NPN phototransistor output with a maximum collector-emitter voltage of 80V and a peak forward current of 50mA. Typical switching characteristics include a rise time of 4µs and a fall time of 3µs. The component is housed in a surface-mount SMD-4 package.
