Spectral Responsivity Curve
Typical Photodiode Spectral Response Curve (%), without Anti
Reflection Coating*
*There is also an option for an Anti Reflection Coating. This will remove the interference
ripples in the figure above. With this special Anti Reflection Coating, the sensitivity curve in
function of wavelength will be somewhat lower (typically 4%) but will no longer display
interference ripples.

9 Applications Information
A typical connection diagram is shown in the figure below. A load resistor RL is needed to get a voltage level
out. The load capacitance CL is typically formed by the input capacitance of the component that is connected
to the sensor output, the wiring capacitance and the output capacitance of the sensor itself.

CL
Decoupling capacitors between Vdd and Vss (1uF in parallel with 100nF) are highly recommended in all configurations.
Recommendation: every change in the application should be agreed by both parties.

12 Standard information regarding manufacturability of Melexis
products with different soldering processes
Our products are classified and qualified regarding soldering technology, solderability and moisture sensitivity
level according to following test methods:
Reflow Soldering SMD’s (Surface Mount Devices)
•
•
IPC/JEDEC J-STD-020
Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices
(classification reflow profiles according to table 5-2)
EIA/JEDEC JESD22-A113
Preconditioning of Nonhermetic Surface Mount Devices Prior to Reliability Testing
(reflow profiles according to table 2)
Wave Soldering SMD’s (Surface Mount Devices)
•
EN60749-20
Resistance of plastic- encapsulated SMD’s to combined effect of moisture and soldering heat
Solderability SMD’s (Surface Mount Devices)
•
EIA/JEDEC JESD22-B102 and EN60749-21
Solderability
For all soldering technologies deviating from above mentioned standard conditions (regarding peak temperature, temperature gradient, temperature profile etc) additional classification and qualification tests have to be
agreed upon with Melexis.
The application of Wave Soldering for SMD’s is allowed only after consulting Melexis regarding assurance of
adhesive strength between device and board.
Melexis is contributing to global environmental conservation by promoting lead free solutions. For more
information on qualifications of RoHS compliant products (RoHS = European directive on the Restriction Of
the use of certain Hazardous Substances) please visit the quality page on our website:
