Opto Diode (Newbury Park, CA) has introduced the SXUVPS4C, a quadrant photodiode with a 5 mm2 active area in each quadrant. The new device is the first of two new SXUV multi-element photodiodes to be introduced. The TO-5 windowless package features a 5-pin header. With light responsivity from 1 to 1000 nm and a shunt resistance of 100 Mohms, the new quadrant photodiode is ideal for 2 axes-positional-centering applications for lasers in the 13.5 nm to 200 nm wavelength range. Operating and storage temperatures range from -10 degrees C to 40 degrees C (ambient) and from -20 degrees C to 80 degrees C (in nitrogen or vacuum conditions). The maximum junction temperature is 70 degrees C and the lead-soldering temperature is 260 degrees C at 0.080 in. from the case for 10 seconds.
