Back-illuminated photodiode array for X-ray non-destructive inspection

The S11212-121 is a back-illuminated type 16-element photodiode array specifically designed for non-destructive X-ray inspection. It has improved sensitivity uniformity and smaller photodiode element variations compared to our previous product (S5668 series). The back-illuminated photodiode array is also simple to handle and easily couples to scintillators without having to worry about wire damage because there are no bonding wires and photosensitive areas on the light incident side. The S11212-121 can be replace the S5668 series since their package size and pin connections are identical.
