• Avalanche photodiode

    The TIEDXX series of high-speed photodiodes operates in the reverse-voltage avalanche region just below the devices` breakdown voltage. This results in a photocurrent signal gain of a magnitude dependent on the reverse voltage and improves the signal-to-noise ratio for many optical receivers. The TIED57 and 58 have 0.010- or 0.030-in. active-area diameters and are hermetically sealed in flat-window, three-lead TO-18 packages. The TIED87 and 88 have internal reference diodes that allow for temper

The TIED87 and 88 have internal reference diodes that allow for temperature compensating of the bias circuit. Applications include LANs, rangefinders, low-light detectors for astronomy, and high-speed medical imaging.
