These photodetectors are based upon Lucent Technologies' patented Advanced Lightwave Platform technology, permitting high optical coupling stability and unparalleled performance. The low-profile package is an 8-lead DIP that allows pinout-equivalent replacements for lower-performance coaxial-type packages. The low profile makes it ideal for close board-to-board spacing situations. The 131-Type PIN Photodetectors contain a rearilluminated planar diode structure. Lucent Technologies employs unique diode processing steps to achieve a low capacitance and highly linear active area that ensures a wide dynamic operating range. Responsivity is typically >0.85 A/W with rise and fall times of <0.5 ns at the 1.3 m wavelength. (N-SIDE) PIN CATHODE RBIAS CAPACITOR dc DECOUPLING CO CPSS LSBW LPBW CPPL PACKAGE GROUND (P-SIDE) PIN ANODE 1-929 Notes: This equivalent circuit is intended as an aid for modeling the device/ package parasitics in order for the circuit designer to better match impedance and optimize bandwidth performance. Minimum parasitic effects can be achieved by connecting the PIN cathode (N-side) to circuit ground, applying a negative voltage to the PIN anode (P-side), and allowing the package voltage to float by not connecting the package ground to circuit ground. Typical values are as follows: CO = Bulk capacitance of the diode = 0.3 pF to 0.5 pF. RNSS, RPSS = Bulk resistance of the contacts = 5 . LSBW = Series inductance of P-side bond wire = 0.25 nH. CNSS, CPSS = Substrate capacitance = 0.975 pF/0.28 pF, respectively. LNBW, LPBW = Series inductance of the substrate to package lead bond wire = 2.0 nH. CNPL, CPPL = Package lead capacitance = 0.40 pF/0.46 pF, respectively. Figure 2.

Typical Bias Connection This PIN's construction involves a patented silicon optical bench that supplies mechanical stability to the fiber and directive channeling of input light. The structure also allows it to handle strong levels of input power. All fiber types are specially terminated inside the package to minimize back reflections. These PIN photodetectors perform effectively and efficiently over the entire 1.1 m to 1.6 m long wavelength range. They have been employed in a number of diverse applications including digital cellular, remote monitoring, high-speed datacom, fiber-to-thecurb, and CATV signaling.

Data Sheet November 2000 131-Type Long-Wavelength PIN Photodetector Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

Take proper precautions during both handling and testing. Follow guidelines such as JEDEC Publication No. 108-A (Dec. 1988). Although protection circuitry is designed into the device, take proper precautions to avoid exposure to ESD. Lucent Technologies employs a human-body model (HBM) for ESD-susceptibility testing and protection-design evaluation. ESD voltage thresholds are dependent on the critical parameters used to define the model. A standard HBM (resistance = 1.5 k, capacitance = 100 pF) is widely used and, therefore, can be used for comparison purposes. The HBM ESD threshold presented here was obtained by using the following circuit parameters: Parameter HBM Threshold Value 250 Unit V Lucent Technologies Inc. 3 131-Type Long-Wavelength PIN Photodetector Data Sheet November 2000 Electrical Characteristics Minimum and maximum values are testing requirements.
