C30902SH-2 - Si APD, 0.5mm, TO-18, Photon Counting, 905nm filter

High Responsivity, Low Noise Reach-Through SPAD

The C30902SH family of Silicon SPADs provide extremely low noise and bulk dark-current enabling very high performance data and distance measurements. They are especially well suited for ultra-low light level detection applications (e.g. single photon counting and quantum communication) and intended for use with optical powers less than 1 pW. The C30902SH-2 can be used in either the linear mode (V_OP < V_BD) at typical gains of 250 or greater, or in “Geiger” mode (V_OP > V_BD) with extremely low and stable dark count rates and after pulsing ratios. In this mode, no amplifiers are necessary and single-photon detection probabilities of up to approximately 50% are possible. For even greater performance, these high performance SPADs are available with single or dual-stage thermoelectric coolers.
