Darlington Output Optocoupler, 4‑Element, 5000 V Isolation
Stock Quantity: 0
The PC845 is a quad-channel Darlington output optocoupler manufactured by SHARP. This device provides electrical isolation between input and output circuits using an LED and a phototransistor. It offers a high isolation voltage of 5000 V, making it suitable for applications requiring reinforced insulation. The PC845 is supplied in a standard DIP package.
This quad optocoupler is typically used in circuits where galvanic isolation is required between control and load circuits. Its Darlington output configuration makes it suitable for driving higher current loads. The PC845 is often found in industrial control systems and power supplies.
