PHOTODIODE
Si PIN photodiode
S2721-02, S3096-02, S4204, S8703
Dual-element, plastic package photodiode
S2721-02, S3096-02, S4204 and S8703 are dual-element Si PIN photodiodes molded into small plastic packages. Having high sensitivity and low
noise, these photodiodes have very low cross-talk between the elements.
Custom devices (with different element shapes, number of elements, characteristics and packages) are also available to meet you specific needs.
Please feel free to contact our sales office.
