Excelitas C30921
The C30902EH series of avalanche photodiodes is ideal for a wide range of applications, including LIDAR, range-finding, small-signal fluorescence, photon counting and bar code scanning. This structure provides high responsivity between 400 and 1000 nm as well as extremely fast rise and fall times at all wavelengths. The responsivity of the device is independent of modulation frequency up to about 800 MHz.| Part No. | C30921 |

APPLICATIONS
● LIDAR● Range finding
● Small-signal fluorescence
● Photon counting
● Bar code scanning Both C30902SH and C30921SH are selected C30902EH and C30921EH photodiodes having extremely low noise and bulk dark-current. They are intended for ultra-low light level applications (optical power less than 1 pW) and can be used in either their normal linear mode (Vr < Vbr) at gains up to 250 or greater, or as photon counters in the “Geiger” mode (Vr > Vbr) where a single photoelectron may trigger an avalanche pulse of about 108 carriers.
