a quadrant photodiode is a 2x2 array of individual photodiode active areas, separated by a small gap, fabricated on a single chip. this maximizes the uniformity and performance matching between the four individual elements. quadrant photodiodes are used most frequently for position sensing of laser beems, autocollimators and other alignment applications. in addition to the devices listed below, pacific silicon sensor can design and manufacture quadrant photodiodes in differing sizes and shapes, enhanced to meet the requirements of your specific application. our quadrant photodiodes are also available in die form or can be mounted on/in any electronic package or substrate compatible with wire bonding. whatever your light sensing problem? make pacific silicon sensor your solution! 5700 corsa avenue, #105, westlake village, ca 91362, phone: (818) 706-3400 , fax (818) 889-7053 email: sales@pacific-sensor.com web site: www.pacific-sensor.com pacific silicon sensor inc. data sheet data sheet quadrant photodiodes: positioning detectors quadrant photodiodes: positioning detectors qp1.16-6 qp5.8-6-to5 qp50-6 qp50-6-18 qp100-6 qp50-6sd2 qp50-6sd-diag part number size (mm) total active area responsivity @ 633nm a/w mm 2 dark current @ 10vr na capacitance @ 10vr pf breakdown voltage v rise time @ 10v, 850nm ns pkg gap m 1.1 x 1.1 1.2 x 1.2 ? 7.98 ? 7.98 ? 11.2 1.16 5.76 50 50 100 20 50 42 18 50 0.45 0.45 0.45 0.45 0.45 1 2 5 5 10 10 10 70 70 130 100 100 40 40 50 30 30 15 15 15 n/a n/a n/a n/a n/a n/a n/a 0.70 0.60 0.50 0.40 0.30 0.20 0.10 0.00 200 250 300 350 400 500 600 wavelength (nm) responsivity (a/w) 700 800 900 1000 1100 50mm 2 quadrant detector module with sum & difference electronics. ready to use with connector.
