Optocoupler, Phototransistor Output, Dual Channel
MCT6
Vishay Semiconductors
DESCRIPTION
The MCT6 is a two channel optocoupler for high density
applications. Each channel consists of an optically coupled
pair with a gallium arsenide infrared LED and a silicon NPN
phototransistor. Signal information, including a DC level,
can be transmitted by the device while maintaining a high
degree of electrical isolation between input and output.
The MCT6 is especially designed for driving medium-speed
logic, where it may be used to eliminate troublesome ground
loop and noise problems. It can also be used to replace
relays and transformers in many digital interface
applications, as well as analog applications such as CRT
modulation.
FEATURES
• Current transfer ratio, 50 % typical
• Leakage current, 1.0 nA typical
• Two isolated channels per package
• Compliant to RoHS Directive and in
accordance to WEEE 2002/96/EC
AGENCY APPROVALS
• UL1577, file no. E52744 system code H, double protection
• DIN EN 60747-5-2 (VDE 0884)/DIN EN 60747-5-5 pending
available with option 1
• CSA 93751
• BSI IEC 60950; IEC 60065
Notes
• Additional options may be possible, please contact sales office.

Note
• 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
• 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.
