UV Enhanced Detector (series -7)
Series 7 Super UV Photodiodes compliment Series 1* and primarily designed for
application in the 194-400 nm range where high shunt resistance and maximum
sensitivity are needed. These detectors are available in a range of standard packages
with a choice of window material to suit specific applications.
Electrical / Optical Specifications
Characteristics measured at 22°C (±2) ambient, and a reverse bias of 30 volts, unless otherwise stated.

Notes: Response limit based on windowless version.
Other available options are:
Q = Quartz Window TO Packaging
CQ = Quartz Window Ceramic Packaging
CO = Open Frame (no window) Ceramic Packaging
U = UV Transmissive Glass (TO packaging only) UV aged versions
For best response below 250nm specify open frame version
Note: Recommended operating voltage range 0 to 10 volts, for all Series 1 Detectors.
