radiation requirements
• High Current Transfer Ratio - 200% typical
• 1kVdc electrical input to output isolation
• Base lead provided for conventional transistor
biasing
• 150 V Breakdown voltage

DESCRIPTION

The 66099-4XX optocoupler consists of a 660 nm GaAIAs LED optically coupled to a high voltage photodiode driving a
high voltage transistor mounted in a hermetic TO-5 package. This configuration has proven to be highly tolerant to both
proton and total dose radiation.
