Optocouplers
Low Voltage Driven Photorelays in Tiny Packages
Toshiba Electronics released a family of five new photorelays housed in the smallest package, the S-VSONR4 (2.0mm x 1.45mm).
6N135 High Speed Optocoupler
The 6N135 is a high speed Optocoupler with Transistor output. It can switch at a speed of 1 Mbit/s with Bandwidth of 2MHz.
MOC3041 Zero-Cross TRIAC Driven Optocoupler
The MOC3021 is a Zero-Crossing TRIAC driven Optocoupler. Meaning it has a Infra-red Light Emitting Diode (LED) inside it coupled with a TRIAC. When the LED is triggered the TRIAC is also turned on.
VOH1016A – 1MBd High Speed Optocoupler with Schmitt-Trigger Functionality
For easy integration with Digital system applications Vishay intertechnology has launched a new series of high speed Optocouplers called VOH1016A. These Optocouplers can operate upto 1MBd and also features an open collector transistor output with Schmitt-Trigger functionality.
6N139 - High Gain Optocoupler IC
6N139 is an optocoupler IC designed for isolating primary circuit and secondary circuit electrically but the pair of LED and photodiode - Darlington setup forms the triggering mechanism between the two sides.
4N28 Optocoupler IC
The 4N28 is an Industry Standard Single Channel Phototransistor Coupler. This family includes the 4N25, 4N26, 4N27 and 4N28.
