Optocoupler, Photodarlington Output, High Gain,
with Base Connection
4N32, 4N33
Vishay Semiconductors
DESCRIPTION
The 4N32 and 4N33 are optically coupled isolators with a
gallium arsenide infrared LED and a solicon photodarlington
sensor.
Switching can be achieved while maintaining a high degree
of isolation between driving and load circuits.
These optocouplers can be used to replace reed and
mercury relays with advantages of long life, high speed
switching and elimination of magnetic fields.
FEATURES
• Very high current transfer ratio, 500 % min.
• High isolation resistance, 1011 typical
• Standard plastic DIP package
• Compliant to RoHS Directive to 2002/95/EC
and in accordance WEEE 2002/96/EC
AGENCY APPROVALS
• UL1577, file no. E52744 system code H
• DIN EN 60747-5-2 (VDE 0884)/DIN EN 60747-5-5
(pending), avialable with option 1
• BSI IEC60950; IEC60065
•FIMKO
Notes
• Additional options may be possible, please contact sales office.
(1) Also available in tubes, do not put T on the end.

Notes
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
(1) Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through
hole devices (DIP).
Notes
• Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluation. Typical values are for information only and are not part of the testing requirements.
