| PHOTODIODE Si photodiode with preamp S9295 series Large area photodiode integrated with op amp and TE-cooler S9295 series is a thermoelectrically cooled Si photodiode with preamp developed for low-light-level detection. A large area photodiode, op amp, TE-cooler and feedback resistor (10 G) are integrated into a single package. A thermistor is also included in the same package for temperature control so that the photodiode and I-V conversion circuit can be cooled for stable operation. S9295 series also features low noise and low NEP, and is especially suitable for NOx detection. The active area of the photodiode is internally connected to the GND terminal making it highly resistant to EMC noise.

As a countermeasure against electro static discharge, the device, operator, work place and measuring jigs must all be set at the same potential. The following precautions must be observed during use: , *To protect the device from electro static discharge which accumulate on the operator or the operator s clothes, use a wrist , strap or similar tools to ground the operator s body via a high impedance resistor (1 M). *A semiconductive sheet (1 M to 10 M) should be laid on both the work table and the floor in the work area. *When soldering, use an electrically grounded soldering iron with an isolation resistance of more than 10 M. *For containers and packing, use of a conductive material or aluminum foil is effective. When using an antistatic material, use one with a resistance of 0.1 M/cm2 to 1 G/cm2. s Strength Thermoelectrically-cooler devices may be damaged if subjected to shock, for example drop impact. Take sufficient care when handling these devices. s Lead forming When forming the leads, take care not to apply excessive force to the lead sealing glass. Excessive force may impair the hermetic sealing, possibly degrading the cooling capacity. To form the leads, hold the roots of the leads securely with a pair of pliers and bend them. s Heatsink Use a heatsink with thermal resistance less than 1.3 C/W. Apply thermal grease between the heatsink and detector package, and then fasten them with the screws. Be careful not to give any excessive force or mechanical stress to the detector package at this point. s Wiring * Be careful not to misconnect the plus and minus leads of the thermoelectric cooler or preamplifier. Supplying a voltage or current while these connections are reversed may damage the device. * The feedback resistor integrated into S9295 series is high so it is susceptible to external noise. Always ground the case terminal when using S9295. Information furnished by HAMAMATSU is believed to be reliable. However, no responsibility is assumed for possible inaccuracies or omissions.
