PC922 Optocoupler Dip-8 IC
The PC922 is a high‑power OPIC (Optical IC) photocoupler produced by Sharp Corporation. It integrates an infrared LED input and dual outputs (O1, O2) including a built‑in base amplifier, making it suitable for high‑current drive such as inverter applications. The device features extremely high isolation of 5 000 Vrms between the input LED and the outputs, which ensures robust protection in electrically noisy or high‑voltage industrial environments.
Features:
- Built‑in base amplifier for inverter drive.
- High power output: O1 up to 0.5 A (DC) and O2 up to 2.0 A (pulse) capability.
- High isolation voltage between input and output: 5 000 Vrms.
- High noise reduction type.
- Fast response: tPLH, tPHL up to 5 µs maximum.
- High sensitivity: input threshold current (IfLH) maximum ~3 mA.
