Two-color detector
K12728-010K
Wide spectral response range: 0.32 to 1.65 μm,
Compact ceramic package
The K12728-010K is a two-color detector in a compact ceramic package, covering a wide spectral response range. Like the
current K1713-09, it incorporates an infrared-transmitting Si photodiode mounted over an InGaAs PIN photodiode, along
the same optical axis. It features low noise and low dark current and supports reow soldering.

After unpacking, store the device in an environment at a temperature range of 5 to 30 °C and a humidity of 60% or less, and perform
reow soldering within 4 weeks.
The thermal stress applied to the device during reow soldering varies depending on the circuit board and the reow oven that is
used.
When setting the reow conditions, verify that the reliability of the device is not compromised by the reow soldering process.
