Hi-Reliability Optically Coupled Isolator

This series of optically coupled 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 offer high-voltage isolation between input and output, electrical isolation in dirty environments, and are suitable for industrial, medical, and office equipment. The suffix letter "D" denotes collector isolation from the case. Devices are processed to MIL-PRF-19500 standards.
