High Speed Si Pin Photodiode
SD0XX-17-51-21X series features 3 high-speed silicon photodiodes that
have been specifically developed for the price-sensitive optical communication
applications, including fiber-optic LAN, VCSEL-based links, and
instrumentation. Designed to be fully depleted at low voltages, the devices
offer exceptionally low capacitance and fast responses. Typical speeds are
from 200 MHz for the large device up to 1GHz for the smallest active area.
Their excellent quantum efficiency, about 70% at 850nm, results in higher
sensitivity than that of many comparable devices but even higher QE’s are
available upon request for the most demanding applications.
All three devices come in rugged, hermetically sealed TO-46 packages that
are suitable for fiber couplers like SMA and ST connectors. The user has a
choice of flat (-211), domed (-214) or microball window (-218) caps. In
addition, almost any fiber connector style is also available upon request. The
assemblies are isolated from their housing, thus offering flexibility in biasing
and minimized EMI susceptibility.
