Opto Diode, an ITW company, has launched the UVG12 photodiode with a 4.1mm diameter active area. With responsivity under test conditions at 254nm, the minimum A/W is 0.105, typical response is 0.115, with a maximum response of 0.125.
The new 13mm² photodiode is designed for detection between 193nm to 400nm and operates at 100 per cent internal quantum efficiency in the UV and visible regions. The UVG12 exhibits less than a two per cent drop in responsivity after exposure to megajoules/cm2 of 254nm light.
Thermal parameters for storage and operation range between -20°C to 80°C. The maximum junction temperature is 80°C and the lead soldering temperature is 240°C (0.0625 inches from the case for 10 seconds).
The photodiodes are ideal for use in applications such as laser power monitoring, photolithography, and other high power density applications utilising ultraviolet light.
