16-element Si photodiode arrays S11212-421 S11212 series S11212-321 S11212-121 S11212-021 Back-illuminated photodiode arrays for X-ray non-destructive inspection The S11212 series 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 back side. The S11212 series can replace the S5668 series since their package size and pin connections are identical.

Avoid storing or using the S11212-121 at high humidity. www.hamamatsu.com 1 16-element Si photodiode arrays Feature S11212 series 01 Back-illuminated type The S11212 series photodiode arrays have a back-illuminated type structure. This structure uses no fragile easily-broken bonding wires since the photodiode array output terminals are directly connected by bump bonding to the electrodes on the board. This structure is robust since the board wiring is laid out within the board. The photodiode surface for coupling the scintillator has no bonding wires or photosensitive areas, so there is less risk of damaging the photodiode array. The S11212 series is also resistant to effects from temperature cycle and so ensures high reliability.

Combination examples (for dual energy imaging) Dual energy imaging is a technique that acquires and superimposes two types of data in a single scan by using X-rays at two different energy levels (high energy and low energy). Two photodiode arrays with scintillators are used: one at the upper stage and the other at the lower stage. The upper stage is used for low energy detection, and the lower stage for high energy detection. Arranging two or more of these devices in a row also forms a line sensor for dual energy imaging. This combination uses the S11212 series in both upper and lower stages.
