VTH2120 Silicon Photodiode, Chip Form
The VTH2120 silicon photodiode with a 100 mm2 active area is offered in chip form for optimal alpha particle detection, such as radon gas detection applications. This photodiode provides an enhanced response to radiation of interest, with a radiation robust chip design and a large active area of 10x10mm.
This low capacitance silicon photodiode provides a 100 mm2 active area and spectral response between 400 nm and 1100 nm.
This series of photodiodes offered in chip form provide high responsivity to alpha particles, enabled by the chip design and by avoiding absorption caused by window assemblies. The large area enables maximum collection of low level radiation. If the application can handle a smaller active area, we also offer the VTH2110 which has an active area of 5x5mm.
These photodiodes are offered either in waffle pack or Mylar (preferred). We can also discuss next level assemblies, please contact our product experts to learn more.
