DIVISION
Rev A July 2008
Features:
High Current Transfer Ratio 1000% typical
25kVdc Isolation
Low input current requirement of 0.5mA
Integral Detector Die Faraday Shield for improved
Common Mode Rejection
DESCRIPTION
The
66325
high voltage isolator consists of an 850nm LED optically coupled to a high gain inverting photon detector. The
isolator provides high CTR and low leakage currents over the specified temperature range of -40oC to +100oC.The isolator is
built with hermetic components internally optically coupled and encased in a high temperature outer PPS plastic housing.
