o MEMS Technology Incorporated into S9723/S9724 to Reduce Size While Maintaining High Performance in Heavy Ion Energy Detection Applications o

Bridgewater, NJ (For Immediate Release 2005) - Hamamatsu Corporation introduces the S9723/S9724 silicon (Si) PIN photodiodes that utilize MEMS technology to maintain a small size yet deliver high performance. Featuring large active areas and low dark currents, the S9723/S9724 are specifically designed for direct detection of high-energy charged particles and X-rays.

The S9723 has a thickness of 100 (+/-5) mm with a 26x26 mm active area while the S9724 is 10 (+/-2.5) mm thick with a 10x10 mm active area. The uniformity of the active areas' thickness is typically 2 mm for the S9723 and 1 mm for the S9724, ensuring that the PIN photodiodes have excellent uniformity over the entire active area. Hole mounted on PC boards, the S9723/S9724 can accurately conduct DE-E detection of the charged particles.

In addition to their size, the S9723/S9724 are well suited for heavy ion energy detection because of their performance. The S9723 has typical dark current of 2 nA and rise time is typically 80 ns. Terminal capacitance of the S9723 is typically 0.75 nF. Typical dark current is 0.01 nA for the S9724, and it has a typical rise time of 100 ns. Terminal capacitance is typically 1 nF for the S9724.

Such high performance is delivered by small PIN photodiodes. The S9723 measures 46 W x 46 D x 1.6 H (mm) while the S9724 is 30 W x 30 D x 1.6 H (mm).

Small quantity pricing is $2,304.00 for the S9723 and $576.00 for the S9724. Delivery is 5 to 6 weeks ARO.
