Document Number: 83669 For technical questions, contact: optocoupleranswers@vishay.com
www.vishay.com
Rev. 1.8, 19-Oct-10 1
High Speed Optocoupler, 100 kBd, Low Input Current, High Gain
SFH6138, SFH6139
Vishay Semiconductors
DESCRIPTION
High common mode transient immunity and very high
current ratio together with 5300 V
RMS
insulation are
achieved by coupling an LED with an integrated high gain
photon detector in an eight pin dual-in-line package.
Separate pins for the photo diode and output stage enable
TTL compatible saturation voltages with high speed
operation.
Photodarlington operation is achieved by tying the V
CC
and
V
O
terminals together. Access to the base terminal allows
adjustment to the gain bandwidth.
The SFH6138 is ideal for TTL applications since the 300 %
minimum current transfer ratio with an LED current of
1.6 mA enables operation with one unit load-in and one unit
load-out with a 2.2 kΩ pull-up resistor.
The SFH6139 is best suited for low power logic applications
involving CMOS and low power TTL. A 400 % current
transfer ratio with only 0.5 mA of LED current is guaranteed
from 0 °C to 70 °C.

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.

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.
