66225
TO-72 RADIATION TOLERANT OPTOCOUPLER
WITH 850 nm LED
OPTOELECTRONIC PRODUCTS
DIVISION
5/21/03

Features:

Designed to meet or exceed MIL-PRF-19500
radiation requirements
High Current Transfer Ratio - 200% typical
500Vdc 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 66225 optocoupler consists of an 850 nm GaAIAs LED optically coupled to a photodiode detector and a 2N2222
transistor all mounted in a hermetic TO72 package. This configuration has proven to be highly tolerant to both proton and
total dose radiation. The 850 nm LED has proven to be more tolerant of operating temperatures over 100C than the more
commonly used 660nm LED.
