SFH6138, SFH6139
Vishay Semiconductors
High Speed Optocoupler, 100 kBd,
Low Input Current, High Gain
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.
(1)
Pin 7 open.
(2)
Device considered a two-terminal device: pins 1, 2, 3 and 4 shorted together and pins 5, 6, 7, and 8 shorted together.
Note
(1)
DC current transfer ratio is defined as the ratio of output collector current, I
O
, to the forward LED input current, I
F
times 100 %. Pin 7 open.
Note
(1)
Pin 7 open. Using a resistor between pin 5 and 7 will decrease gain and delay time.
