66099 RADIATION TOLERANT TO-5 OPTOCOUPLER
09/09/03
Features:
• Meets or exceeds MIL-PRF-19500 radiation
requirements
• Current Transfer Ratio-150% typical
• 1kVdc electrical input to output isolation
• Base lead provided for conventional transistor
biasing
Applications:
• Eliminate ground loops
• Level shifting
• Line receiver
• Switching power supplies
• Motor control
DESCRIPTION
The 66099 Optocoupler consists of a 660 nm GaAIAs LED optically coupled to a photodiode detector driving a radiation
tolerant transistor. This configuration has proven to be highly tolerant to both proton and total dose radiation. Available as
standard and high voltage and commercial or screened levels.
