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.
