Overview: S-5420 .ablic. © ABLIC Inc., 2018-2019 ULTRAVIOLET LIGHT SENSOR, UV-A to UV-B SENSING Si PHOTODIODE
Rev.1.2_00 The S-5420 is a photodiode (PD) made of silicon that can detect ultraviolet light at high sensitivity. The output current changes in reaction to light which includes ultraviolet light. Therefore, the S-5420 can detect light intensity of various light sources for LEDs and other devices. Since the S-5420 can detect ultraviolet light intensity, it is particularly well suited for use in various light measurement devices which irradiate ultraviolet light. The S-5420 is posed of two types of ultraviolet photodiodes, a high-sensitivity and a low-sensitivity photodiodes. Using an external circuit, the S-5420 takes the difference of output between the high-sensitivity and low-sensitivity photodiodes, which cuts out visible light ponents. It results in ultraviolet ponents detection. Incorporating a surface-mounting type, small, transparent package, the S-5420 allows for high-density mounting. Remark This product is jointly developed with Sugawa and Kuroda Laboratory of Graduate School of Engineering, Tohoku University.
