BPW97
Vishay Telefunken
Silicon PIN Photodiode
Description
BPW97 is an extra high speed PIN photodiode in a
hermetically sealed TO鈥?8 package.
Unlike most similar devices, the cathode terminal is
isolated from case and connected to a third terminal,
giving the user all the means to improve shielding of his
system.
Due to its high precision flat glass window and its accu-
rate chip alignment, this device is recommended for
ambitious applications in the optical data transmission
domain.
