Description

The D171-Type Photodetector consists of a PIN cou­pled 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 manufac­turing 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 requir­ing high perfomance and low cost.

Notes:
This equivalent circuit is intended for modeling the package
capacitance. Minimum capacitance is achieved by connecting the N­side to ground, applying a negative voltage to the P-side, and allowing
the package to float (i.e., not connected to ground).

Typical values are as follows:
CO = 0.3 pF to 0.5 pF.
LN, LP = 3.0 nH.
RN, RP = 5 Ω.
CN = 0.4 pF.
CP = 0.1 pF.

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.

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.
