The PC851XNNSZ1H is a single-channel optocoupler manufactured by Sharp, featuring an infrared LED input and a phototransistor output. It provides electrical isolation between circuits with a voltage isolation rating of 5000Vrms. The device supports a maximum output voltage of 350V and can handle a continuous output current of 50mA per channel. It operates within a temperature range of -25°C to 100°C and utilizes a DIP4 package.
Verify the exact suffix against official Sharp documentation to confirm pinout and packaging variations. Ensure compatibility with required isolation voltage standards for your specific application design before procurement.
Select this component when high isolation voltage is required for single-channel signal transfer. Consider the 50mA output current capability and operating temperature range to ensure suitability for the target environment.
This part belongs to Sharp's series of single-channel optocouplers designed for general-purpose isolation. It is commonly used in industrial and consumer electronics where galvanic isolation is necessary to protect sensitive components from high voltages.
Check for direct replacements with identical pinouts and electrical ratings. Verify that any substitute maintains the 5000Vrms isolation and 50mA output current specifications.
