Chip on carrier photodiode array VTA0832H-H-NC-00-0

Overview
The VTA0832H-H-NC-00-0 is a silicon photodiode array (PDA) designed for X-ray detection. This 32-element device features a 0.8 mm pitch and is supplied mounted on an FR-4 PCB. Units can be ordered with or without scintillator crystals to suit high- or low-energy X-ray systems.

Key features

• 32 channels (16 dual-element photodiodes)
• 0.8 mm sensor-to-sensor pitch
• Extremely low dark current for improved detector performance
• High signal-to-noise characteristics suitable for imaging and detection
• Optional scintillator crystals available to convert X-rays to visible photons
• Transparent coating over photosensitive area and glob-top encapsulation for wire protection

Applications

• Medical and dental X-ray imaging systems
• Industrial X-ray inspection and non-destructive testing (NDT)
• Security scanning and baggage inspection
• Scientific instrumentation requiring linear X-ray detectors
