basic information
The "Illuminance Sensor PT337P11" is a top-view pin package illuminance sensor that uses a phototransistor with peak sensitivity close to the human relative visual sensitivity (λm=560nm). It can be used in a range from 1 lux to 500 lux, with a photocurrent of 60μA at 10 lux. Additionally, the dark current is minimal at 10nA. The "Illuminance Sensor PT337P11A" has the same basic characteristics as the "PT337P11," but it covers a usage range from 1 lux to 1000 lux. Furthermore, it reduces the light source difference, with a ratio of 1.1 times for A source to B source, and 1.7 times for incandescent to fluorescent lamps. The "Illuminance Sensor PT337P11FA" is designed with a pin pitch of 3.4mm, matching the standard pin pitch of CdS cells, based on the "PT337P11A."

Applications/Examples of results
- Lighting devices that "turn on" when it gets dark and "turn off" when it gets bright. Additionally, a "mute" circuit that requires the opposite operation. - A "brightness adjustment" circuit that optimally adjusts the brightness of TVs, PCs, and other monitor screens based on the brightness outside. - A "human detection" circuit that detects human shadows, such as in sanitary equipment.
Company information
1. Optical Sensing Related Optical sensors have a proven track record with major home appliance and industrial equipment manufacturers as core products, and we are advancing the development of optical, circuit, and mechanical designs to meet diverse sensing requirements. We are developing mixed-signal ICs that incorporate digital processing circuits, leveraging the features of fine sensing through 3D processing and sub-micron C-MOS wafer processes, resulting in compact, high-performance, high-value-added products. 2. Optical Media Related We have a wide range of products and a proven track record in CD/DVD technology. In response to market demands for high-speed and short-wavelength applications such as Next DVD, we are advancing the development of dedicated epitaxial equipment and processes for miniaturization. We plan to ship sample products of silicon photodetectors that utilize the quantum effects of ZnO/Si heterojunctions, which exhibit blue sensitivity and high-speed performance.
