TO-72 RADIATION TOLERANT OPTOCOUPLER
WITH 850 nm LED
OPTOELECTRONIC PRODUCTS DIVISION
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 100°C than the more commonly used 660nm LED. ABSOLUTE MAXIMUM RATINGS Input Diode Forward DC Current........50mA Input Power Dissipation (see Note 1)..............80mW Reverse Input Voltage .... 7V Collector-Emitter Voltage ............. 40V Continuous Collector Current .... 50mA
Continuous Transistor Power Dissipation (see Note 2)..230mW
Storage Temperature.........-65°C to +150°C Operating Free-Air Temperature Range ...-55°C to +125°C Lead Solder Temperature (1/16" (1.6mm) from case for 5 seconds) ........ 240°C Notes: 1. Derate linearly @ 0.80 mW/°C above 25°C. 2. Derate linearly @ 2.3 mW/°C above 25°C. Package Dimensions Schematic Diagram
