emitting diode, optically coupled to an integrated photo
detector consisting of a photo diode and a high speed APPLICATIONS
transistor in a DIP-8 plastic package. The device is similar to • Data communications
the 6N135 but has an additional Faraday shield on the
detector which enhances the input-output dV/dt immunity. • IGBT drivers
Signals can be transmitted between two electrically • Programmable controllers
separated circuits up to frequencies of 2 MHz. This an ideal • IPM (intelligent power module) drivers
solution for industrial communication bus isolation, as well
as isolated drive circuit applications such as IPM (intelligent AGENCY APPROVALS
power module) drivers. • UL1577 file no. E52744, double protection
• DIN EN 60747-5-5 (VDE0884-5) available with option 1
• cUL components acceptance service no. 5A
• CQC GB8898-2001, GB4943.1-2011
