Description
The D171-Type Photodetector consists of a PIN cou- pled to a multimode fiber pigail. The device is available in a 4-pin mini-DIL configuration (see Figure 3 and/or Table 1) and is ideal for long-reach (SONET) and other high-speed digital applications. The D171-Type PIN Photodetector is a rear-illuminated planar diode structure with a low-capacitance active area for maximum responsivity and speed. This device incorporates the new Laser 2000 manufac- turing process from the Optoelectronics Products unit of Lucent Technologies Microelectronics Group. Laser 2000 is a low-cost platform that targets high-volume manufacturing and tight product distributions on all optical subassemblies. This platform incorporates an advanced optical design that is produced on Opto’s highly automated production lines. The Laser 2000 platform is qualified for central office and uncontrolled environments, and can be used for applications requir- ing high perfomance and low cost. Figure 1.

3Lucent Technologies Inc. Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso- lute 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. * The recommended reverse bias voltage is 5 V to 15 V. Handling Precautions Electrostatic Discharge CAUTION: This device is susceptible to damage as a result of electrostatic discharge. 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.
Electrical Characteristics
T C = 25 C. Determined with a 50 W load. * The minimum capacitance configuration occurs when the N-side of the PIN is grounded and a negative voltage is applied to the P-side, with the package floating, not grounded (value reference only; not tested in manufacture).
