Product Description
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 military 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 that the collector is electrically isolated from the case. Devices with the 'D' or 'DS' suffix are processed to MIL-PRF-19500/486 or MIL-PRF-19500/548.
