Description
The R2560A incorporates a high-speed planar PIN
diode to provide a highly reliable, high-power photo-
diode module. This module is well suited for receiver
applications with optical preamplification. The diode
is well matched over the operating frequency band,
thereby simplifying high-speed integration.

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.
