Si APD
S12426-02
Low bias, high-speed Si APD for 900 nm
The S12426 series Si APD are designed to provide a peak sensitivity wavelength in the 900 nm band where optical rangefinders are increasingly used. The S12426 series delivers faster response and lower bias operation than our existing Si APD (S9251 series).
Features
- Peak sensitivity wavelength: 840 nm (gain=100)
- Low bias operation: Breakdown voltage=200 V max.
- High-speed response: Cutoff frequency=650 MHz typ. (S12426-02, λ=900 nm, M=100)

1. What are cookies?
For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website. Cookies are used in order to make websites function and work efficiently. Cookies are uniquely assigned to each visitor and can only be read by a web server in the domain that issued the cookie to the visitor. Cookies cannot be used to run programs or deliver viruses to a visitor’s device.
Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive. For instance, cookies are used to remember the visitor’s preferences on sites they visit often, to remember language preference and to help navigate between pages more efficiently. Much, though not all, of the data collected is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve the visitor experience.

5. What are Internet tags and how do we use them with cookies?
Occasionally, we may use internet tags (also known as action tags, single-pixel GIFs, clear GIFs, invisible GIFs and 1-by-1 GIFs) at this site and may deploy these tags/cookies through a third-party advertising partner or a web analytical service partner which may be located and store the respective information (including your IP-address) in a foreign country. These tags/cookies are placed on both online advertisements that bring users to this site and on different pages of this site.
