4N27 General Purpose Phototransistor Optocoupler 70V 50A IC DIP-6

From the shop's description

4N27 General Purpose Phototransistor Optocoupler 70V 50A IC DIP-6 The 4N25 family is an Industry Standard Single Channel Phototransistor Coupler. This family includes the 4N25/ 4N26/ 4N27/ 4N28. Each optocoupler consists of gallium arsenide infrared LED and a silicon NPN phototransistor. These couplers are Underwriters Laboratories (UL) listed to comply with a 5300 VRMS isolation test voltage. This device is widely used for signal isolation in microcontroller interfaces, logic coupling, telecommunication circuits, power supply feedback, and systems requiring protection from high voltages or noise. Its compact 6-lead dual-inline package makes it easy to integrate into through-hole designs. Features: Optical isolation between input and output. High electrical noise immunity. Infrared LED to phototransistor coupling. Fast switching response. Stable current transfer performance. Low power consumption. High reliability and long operating life. Compact through-hole package.
