s Typical connection to photodiode
• To connect a photodiode to C9051, use a coaxial cable terminated with a
BNC plug. The cable length (capacitance) should be less than 15 nF
including photodiode terminal capacitance.
• Solder the photodiode leads to connect the tip of the cable wire. (See the
drawing on the right.)
Anode: Connect to the shield wire of the cable. (Make electrical connection
with the shield.)
Cathode: Connect to the core wire of the cable.
• To improve measurement accuracy, provide a shield around the photodiode.
Do not use a cable any longer than necessary. (Keep the cable as short as
possible.)

NOTE) When using a photodiode whose cathode is internally connected to its
metal package, secure the photodiode with an insulating material
when shielding. Otherwise, signal current cannot be drawn when the
photodiode package is grounded.
