High UV sensitivity and UV resistance

Compact Si photodiode suitable for monitoring powerful UV light sources "S15289-33"

The S15289-33 is a back-illuminated Si photodiode that combines the features of current UV photodiodes (highly UV-sensitive S1337 series and highly UV-resistant S12698 series) with a compact CSP (chip size package) structure.

It is suitable for applications such as monitoring of intense UV light sources because of its high sensitivity in the UV region and minimal degradation of sensitivity caused by UV radiation.

Compared to the current products, it is more compact, enabling it to be mounted in tight spaces and mounted on small and thin light monitoring devices.
In addition, multiple products can be tiled side by side due to the small dead space along the product's edges.

It can also be used for various analytical and optical measurement equipment.

Features

1) High sensitivity in UV region: QE=75% (λ=200 nm)

2) High resistance to UV light's degradation effects

3) The CSP structure allows multiple products to be tiled side by side

4) Compatible with lead-free solder reflow
