This datasheet also covers the 4N47 variant, as both devices belong to the same hi-reliability optically coupled isolator family and are provided as variant models within a single manufacturer datasheet.
General Description
Each isolator in this series consists of an infrared emi ng diode and a NPN silicon phototransistor, which are mounted in a herme cally sealed TO‐78 package.
Devices are designed for military and/or harsh environments.
The suffix le er “A” denotes the collector is electrically isolated from the case.
Key Features
TO-78 hermetically sealed package.
High current transfer ratio.
1 kV electrical isolation.
Base contact provided for conventional transistor biasing.
XV) Features: TO-78 hermetically sealed package High current transfer ratio 1 kV electrical isolation Base contact provided for conventional transistor biasing TX and TXV devices processed to MIL-PRF-19500 Description: Each isolator in this series consists of an infrared emi ng diode and a NPN silicon phototransistor, which are mounted in a herme cally sealed TO‐78 package. Devices are designed for military and/or harsh environments. The suffix le er “A” denotes the collector is electrically isolated from the case. The 4N22, 4N22A, 4N23, 4N23A,4N24, and 4N24A (TX, TXV) devices are processed to MIL‐PRF‐19500/48
