Note 1. At the DC reverse operating voltage VRsupplied with the device and a light spot diameter of 0.25 mm (C30902E, S) or 0.10 mm (C30921E, S). Note that a specific value
of VRis supplied with each device. When the photodiode is operated at this voltage, the device will meet the electrical characteristic limits shown above. The voltage value will be
Note 2. The theoretical expression for shot noise current in an avalanche photodiode is in= (2q (Ids+ (IdbM2+ PoRM) F) Bw)1/2where q is the electronic charge, Idsis the dark
surface current, Idbis the dark bulk current, F is the excess noise factor, M is the gain, Pois the optical power on the device, and Bw, is the noise bandwidth. For these devices F =
0.98 (2-1/M) + 0.02 M. (Reference: PP Webb, RJ McIntyre, JJ Conradi, "RCAReview", Vol. 35 p. 234, (1974)).
Note 3. The C30902S and C30921S can be operated at a substantially higher Detection Probabilities. See Appendix.
Note 4. After-Pulse occurring 1 microsecond to 60 seconds after main pulse.
