Product Description
Hi-Reliability Optically Coupled Isolator
This series of optically coupled isolators consists of an infrared emitting diode and a silicon phototransistor, housed in a hermetically sealed TO-78 package. Designed for military and harsh environments, these devices provide high-voltage isolation between input and output. The suffix letter 'D' denotes that the collector is electrically isolated from the case. Devices are processed to MIL-PRF-19500 standards.
