The FT-W3120 consists of an infrared light emitting diodes and integrated high gain, high-speed photo detectors. The device is housed in an 8 pin DIP wide body package and available in SMD package option.
The photo detector has an internal shield that provides a guaranteed common-mode transient immunity of ±20 kV/μs. It is suitable for direct gate driving circuit for IGBTs or power MOSFETs.
