Kyoto Semiconductor Announces Two UV Sensors for Deep UV Sensing Applications
7.2.2023 04:30:00 EET | Business Wire | Press release
Kyoto Semiconductor Co., Ltd. (President and CEO Yoshihisa Shinya, Head office: Fushimi-ku, Kyoto city), a leading optical device solution manufacturer with world-class technologies and Japanese quality, has announced two products of GaN*1 UV sensor; "KPDU086SU27-H11Q and KPDU086SU31-H11Q".

The UV sensors "KPDU086SU27-H11Q" and "KPDU086SU31-H11Q" were developed with the aim of achieving higher sensitivity than conventional Si*2 type UV sensors to meet the needs of the deep UV*3 sensing market.
Since conventional Si-type UV sensors detect a wide range of wavelengths, it is common to apply a filter to limit the sensitivity to the UV wavelength range. The amount of light was attenuated by passing through the filter.
The newly developed KPDU086SU27-H11Q and KPDU086SU31-H11Q use GaN to enable direct light reception at the light receiving part of the sensor without using a filter as GaN has sensitivity to a specific wavelength range of ultraviolet light. It is now possible to obtain approximately three times as high sensitivity as Si-type UV sensors. *4
In addition, the products have sensitivity in the wavelength range limited to UV-B*5 and UV-C*6, which are in high demand among ultraviolet rays.
The new products can be used to monitor the ultraviolet light intensity of germicidal lamps in food factories, medical institutions, and water purification-related institutions, and to monitor the light intensity of ozone detection light sources.
The mass production of the GaN UV sensors "KPDU086SU27-H11Q and KPDU086SU31-H11Q" are scheduled to start on April 28, 2023.
