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.

Notes:

This equivalent circuit is intended for modeling the package

capacitance. Minimum capacitance is achieved by connecting the N-

side 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:

= 0.3 pF to 0.5 pF.

Absolute Maximum Ratings

Stresses in e xcess of the absolute maxim um 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.

* 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).
