Hi-Reliability Optically Coupled Isolator
JAN / JANTX / JANTXV 4N47, 4N48, 4N49 [A]
Features:
TO-78 hermetically sealed package
High current transfer ratio
1 kV electrical isolation
Base contact provided for conventional transistor biasing
JAN, JANTX and JANTXV devices processed to MIL-PRF-
19500
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 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 JAN / JANTX / JANTXV 4N47, 4N47A, 4N48, 4N48A, 4N49, and 4N49A devices are processed to MIL-PRF-
19500/548.
This series of 4N products are JEDEC registered, DSCC qualified.
Please contact your local representative or OPTEK for more information.
Applications:
High-voltage isolation between input and output
Electrical isolation in dirty environments
