TSL12T, TSL13T Light-to-Voltage Converters General Description The TSL12T and TSL13T are cost-optimized, highly integrated light-to-voltage optical sensors, each combining a photodiode and a transimpedance amplifier (feedback resistor = 80M and 20M, respectively) on a single monolithic integrated circuit. The photodiode active area is 0.5mm x 0.5mm and the sensors respond to light in the range of 320nm to 1050nm. Output voltage is linear with light intensity (irradiance) incident on the sensor over a wide dynamic range. These devices are supplied in a low-profile surface-mount package (T). Ordering Information and Content Guide appear at end of datasheet.

Page 18 Document Feedback ams Datasheet [v1-00] 2016-Apr-12 TSL12T, TSL13T - Manufacturing Information Moisture Sensitivity Optical characteristics of the device can be adversely affected during the soldering process by the release and vaporization of moisture that has been previously absorbed into the package. To ensure the package contains the smallest amount of absorbed moisture possible, each device is dry-baked prior to being packed for shipping. Devices are packed in a sealed aluminized envelope called a moisture barrier bag with silica gel to protect them from ambient moisture during shipping, handling, and storage before use. This package has been assigned a moisture sensitivity level of MSL 3 and the devices should be stored under the following conditions: * Temperature Range: 5C to 50C * Relative Humidity: 60% maximum * Total Time: 6 months from the date code on the aluminized envelope - if unopened * Opened Time: 168 hours or fewer Rebaking will be required if the devices have been stored unopened for more than 6 months or if the aluminized envelope has been open for more than 168 hours. If rebaking is required, it should be done at 90C for 4 hours. ams Datasheet [v1-00] 2016-Apr-12 Page 19 Document Feedback TSL12T, TSL13T - Ordering & Contact Information Ordering & Contact Information Figure 29: Ordering Information Ordering Code Device TA Package - Leads Package Designator TSL12T TSL12 0C to 70C 4-lead Low-Profile Surface-Mount T TSL13T TSL13 0C to 70C 4-lead Low-Profile Surface-Mount T Buy our products or get free samples online at: www.ams.com/ICdirect Technical Support is available at: www.ams.com/Technical-Support Provide feedback about this document at: www.ams.com/Document-Feedback For further information and requests, e-mail us at: ams_sales@ams.com For sales offices, distributors and representatives, please visit: www.ams.com/contact Headquarters ams AG Tobelbaderstrasse 30 8141 Premstaetten Austria, Europe Tel: +43 (0) 3136 500 0 Website: www.ams.com Page 20 Document Feedback ams Datasheet [v1-00] 2016-Apr-12 TSL12T, TSL13T - RoHS Compliant & ams Green Statement RoHS Compliant & ams Green Statement RoHS: The term RoHS compliant means that ams AG products fully comply with current RoHS directives.
