DATASHEET Optoelectronics C30645E/C30662E Series InGaAs Avalanche Photodiode Description The C30645E/C30662E are high speed, large area lnGaAs/lnP avalanche photodiodes. These devices provide high Q.E., high responsivity and low noise in the spectral range between 1100nm and 1700nm.They are optimized for use at a wavelength of 1540nm, suitable for use in eye-safe laser range finding systems. These APDs are supplied in a hermetically sealed TO-18 package or on a ceramic carrier. Custom packaging is also available. Please contact PerkinElmer Optelectronics Canada to discuss the packaging in further detail. Applications OTDR Eye safe range finding Features Spectral response (1100 to 1700nm) High responsivity Quality & Reliability PerkinElmer Optoelectronics Canada is committed to supplying the highest quality product to our customer. We are certified to meet ISO-9001 and we are designed to meet MIL-STD-883 and/or MIL-STD-750 specifications. All devices undergo extended burn-in and periodic process qualification programs to assure high reliability.

When the photodiode is operated at this voltage (at 22°C), the device will meet the electrical characteristic limits shown above. The voltage value will be within the range of 40 to 70 volts. 2. The voltage dependence of the gain, for gains above 4, is given approximately by the following empirical formula: M =50/ (Vb-Vop). Rough approximate of the sensitivity. 3. Gain and quantum efficiency are not directly measurable quantities. The numbers quoted are estimated typical values. Gain, quantum efficiency and responsivity are related by the following: R =ŋλM /1.24 where λ is the wavelength in units of mm, ŋ is the quantum efficiency, M is gain. 4. The detector noise current / Hz1/2 is given by the following expression: in = (2q (ls+lbM 2 F)) 1/2 Where: F = keffM + (1 - keff) (2-1/M) and ls and lb are the unmultiplied and multiplied portions of the dark current, respectively. The total dark current is given by: It = ls+lbM. However, since both ls and lb are somewhat voltage dependent, and M is not directly measurable (see Note 3), it is not usually possible to determine both ls and lb unambiguously. Since system performance depends on noise current and responsivity, these measurable quantities are the ones that have been specified. 5. Most devices can be operated at gains up to about 30 or more, but with values of noise current correspondingly higher, as indicated by the discussion in Note 4 above. www.optoelectronics.perkinelmer.com Page 2 InGaAs Avalanche Photodiode C30645E/C30662E Series Table 2.
