131-Type Long-Wavelength PIN Photodetector
Description
The 131-Type photodetectors represent a family of low-
profile, high-reliability pigtailed devices specially
engineered for the rigorous demands of either analog
applications or digital fiber-optic applications. These
photodetectors are based upon Lucent Technologies’
patented Advanced Lightwave Platform technology,
permitting high optical coupling stability and
unparalleled performance.
Low-profile package choices are an 8-lead DIP or a
3-lead out-the-back style, thus allowing pinout-
equivalent replacements for lower-performance
coaxial-type packages. Their low profile makes them
ideal for close board-to-board spacing situations.
The 131-Type PIN Photodetectors contain a rear-
illuminated 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
µ
m wavelength.
Figure 1. 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
µ
m to 1.6
µ
m long
wavelength range. They have been employed in a
number of div erse applications including digital cellular ,
remote monitoring, high-speed datacom, fiber-to-the-
curb, and CATV signaling.
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:

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.
* 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 Pub lication 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
e valuation. 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:
