Vishay Semiconductors Optocoupler, Phototransistor Output
Notes
(1) Tamb = 25 °C, unless otherwise specified.
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.
(2) Refer to wave profile for soldering conditions for through hole devices.
Note
Tamb = 25 °C, unless otherwise specified.
Minimum and maximum values are testing requierements. Typical values are characteristics of the device and are the result of engineering
evaluations. Typical values are for information only and are not part of the testing requirements.
Note
According to DIN EN 60747-5-5. This optocoupler is suitable for safe electrical isolation only within the safety ratings. Compliance with the safety
ratings shall be ensured by means of suitable protective circuits.
