HiReliability Optically Coupled Isolator Features: TO78 hermetically sealed package High current transfer ratio 1 k electrical isolation Base contact provided for conventional transistor biasing TX and TX devices processed to MILPRF19500 Patent No. 4124860 Description: Each isolator in this series consists of an infrared emitting diode and a NPN silicon phototransistor, which are mounted in a hermetically sealed TO78 package. Devices are designed for military and/or harsh environments. The suffix letter A denotes the collector is electrically isolated from the case. The 4N22, 4N22A, 4N23, 4N23A,4N24, and 4N24A (TX, TX) devices are processed to MILPRF19500/486. The 4N47, 4N47A, 4N48, 4N48A, 4N49, and 4N49A (TX, TX) devices are processed to MILPRF19500/548. Please contact your local representative or OPTEK for more information.
