epc300 to epc330 – high sensitive Photodiode Arrays

The epc3xx family products are high-sensitive photodiode arrays for light-barrier, light-curtain and the like applications with following configurations: 2×1, 4×1, 4×2, 8×2 elements. They are designed to be used in a reverse-bias mode with a bias voltage between 1.5 and 20 Volts. The individual diodes feature a very high quantum efficiency of 90% in the near IR range and a response time down to less than 100ns. The advanced Chips Scale Package (CSP) makes them ideal for miniaturized systems where a minimal space requirement is key. This device allows the design of short to long range light barriers from a few millimeters up to tens of meters.
