Si Pigtailed Photodiodes

The device is a compound Si-PIN structure. To reach high response, back side hole etching process is used for thinner I layer, when carrier go through the floating area, optical current will appear .Slow optical carrieIP are shorted for fast response purpose.We has our Patented package Desgin-“Bullet” design adopts Two optimized chips special for different wavelength. One we called Circle Chip and the other is square Chip.
