NVD NVDX ARRAYS NIGHT VISION H.V. RECTIFIER DIODES & ARRAYS These diodes and arrays have been specifically designed for use in night vision and image intensifier equipment power supplies. They offer unusual characteristics that have not been previously available. As a result of a proprietary EDI diffusion process, they feature small size and a unique combination of extremely low leakage and ultra fast recovery time.
