The ONSEMI 6N135M is a single-channel optocoupler that combines an AlGaAs LED with a high-speed photodetector transistor. Its design reduces base-collector capacitance, enabling faster switching speeds compared to conventional optocouplers. The device is suitable for applications requiring high isolation voltage, such as line receivers, pulse transformer replacements, and output interfaces to CMOS, LSTTL, and TTL circuits. It offers a 5,000 VRMS isolation rating and is recognized under U.L. File # E90700.
