4N47A Datasheet PDF - TT Electronics.

Description:
Each isolator in this series consists of an infrared emiƫng diode and a NPN silicon phototransistor, which are mounted in a hermeƟcally sealed TO‐78 package. Devices are designed for military and/or harsh environments. The suffix leƩer “A” denotes the collector is electrically isolated from the case

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

APPLICATIONs:
● High-voltage isolation between input and output
● Electrical isolation in dirty environments
● Industrial equipment
● Medical equipment
● Office equipment
