Hi-Reliability Optically Coupled Isolator

This series of isolators features an infrared emitting diode and a silicon phototransistor housed in a hermetically sealed TO-78 package. Designed for and harsh environments, these devices provide high-voltage isolation between input and output, electrical isolation in dirty environments, and are suitable for industrial, medical, and office equipment. Devices with the suffix 'D' denote that the collector is electrically isolated from the case. Models 4N22, 4N23, 4N24, 4N48, and 4N49 are processed to MIL-STD-19500/486, while models 4N47, 4N48, and 4N49 are processed to MIL-STD-19500/548.
