Proton Radiation Tolerant Optocoupler (Single Channel, Electrical Equivalent To 66099)

66191-101
The 66191 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. Radiation tests performed on the 66099 optocoupler have shown that the electrical performance of the device after irradiation is an order of magnitude better than the 4N49 optocouplers. The 66191 has the same components and layout in a 6 pin, hermetically sealed leadless chip carrier package. Available as commercial or screened levels.

Features

· Current Transfer Ratio - 150% typical
· Base lead provided for conventional transistor biasing
· Low power consumption
· High radiation immunity
· 1000 Vdc isolation test voltage

Applications

· Military and Space
· High Reliability Systems
· Voltage level shifting
