Opto Diode Debuts High Speed Photodiode

Opto Diode, a division of ITW, announced the launch of the SXUV20HS1, a high-speed photodiode with a Ø 5 mmcircular active area. The new detector is ideal for extreme ultraviolet (EUV) detection covering 1 to 200 nm. It is designed to dissipate the optical energy of high-powered UV lasers without the typical measurement degradation that occurs with prolonged exposure to UV. Optimized to provide stable responsivity for consistent, repeatable measurements, it is ideal for any high-speed laser power monitoring applications.

Highly stable, the SXUV20HS1 sensitive area is 19.7 mm2, grid lines are at 5 microns with the pitch at 100 microns. Shunt resistance is 5 MOhms and capacitance is typically 200 pF to a maximum of 800 pF. The high-speed device parameters include reverse breakdown voltage at 160 V (minimum), dark current of 100 nA (under test conditions of 150 V), and a rise time of 2 nanoseconds (maximum).

RoHS and REACH compliant, Opto Diode’s new photodiode is suited for applications such as photolithography, where tight control of the laser’s output, a fast response and measurement stability are critical.
