Dual Photo Diode

Prema Semiconductor announces the release of their first optical standard component PR5001, a dual photo diode for the near infrared range. An active area of two times 0.75mmx1.2mm is packaged in a clear DFN package with a size of 1.8mmx2.9mm. Prema´s silicon photo diodes have separate cathodes and a common anode. They offer a low dark current in the range of less than 100pA at reverse voltages of up to 20V. The capacitance of the photo diodes of less than 60pF at 10Volts allows the use for light signals of higher frequency.

PR5001 has its peak sensitivity in the near infrared range around 890nm. Possible applications for these dual photo diodes are light measurement, laser beam alignment in laser printers and DVD/CD players, the use in optical encoders and light barriers.
