OPTOISO 1kV TRANS W/BASE TO78-6
Description:
Each isolator in this series consists of an infraredemitting diode and a NPN silicon phototransistor, which are mounted in a hermetically sealed TO-78 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, TXVdevices are processed to MIL-PRF-19500/486.
The 4N47, 4N47A, 4N48, , 4N49, and 4N49A TX, TXV devices are processed to MIL-PRF-19500/548.
