InAsSb photovoltaic detector


High-speed response and high sensitivity in the spectral band up to 11 μm,non-cooled type infrared detectors


The P13894 series are photovoltaic type detectors that have achieved high sensitivity in the spectral range up to 11 μm using Hamamatsu unique crystal growth technology and process technology. These products are environmentally friendly infrared detectors and do not use mercury or cadmium, which are substances restricted by the RoHS Directive. They are replacements for previous products that contain these substances. A compact surface mount type has been added to the easily handled non-cooling type.

-High sensitivity
-High-speed response
-High shunt resistance
-Non-cooled (P13894-011CN/-011NA/-011MA)
-Compact, surface mount ceramic package
-Compatible with lead-free reflow soldering



The chip of this product is not sealed and is exposed. Parts such as electrodes on the chip are not protected by an enclosure or window and so require especially strict care during handling compared to ordinary products.
Before using this product, always read “Precautions / Unsealed products” described below.
