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 = 80MΩ and
20MΩ, respectively) on a single monolithic integrated circuit.
The photodiode active area is 0.5mm × 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.

Note(s):
1. Measurements are made with RL = 10kΩ between output and ground.
2. Optical measurements are made using small-angle incident radiation from an LED optical source.
3. The 640nm input irradiance E e is supplied by an AlInGaP LED with peak wavelength λp = 640nm.
4. Irradiance responsivity is characterized over the range V O = 0.2 to 4V. The best-fit straight line of Output Voltage VO versus irradiance
Ee over this range may have a positive or negative extrapolated VO value for E e = 0. For low irradiance values, the output voltage VO
versus irradiance Ee characteristic is non linear with a deviation toward V O = 0, Ee = 0 origin from the best-fit straight line referenced
above.

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: 5°C to 50°C
• 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 90°C for 4 hours.

Statement
RoHS: The term RoHS compliant means that ams AG products
fully comply with current RoHS directives. Our semiconductor
products do not contain any chemicals for all 6 substance
categories, including the requirement that lead not exceed
0.1% by weight in homogeneous materials. Where designed to
be soldered at high temperatures, RoHS compliant products are
suitable for use in specified lead-free processes.
ams Green (RoHS compliant and no Sb/Br): ams Green
defines that in addition to RoHS compliance, our products are
free of Bromine (Br) and Antimony (Sb) based flame retardants
(Br or Sb do not exceed 0.1% by weight in homogeneous
material).
