IS127 Darlington Optocoupler, 1 Channel, SOP, 4 Pin, 3.75kV

The IS127 Darlington Optocoupler from ISOCOM COMPONENTS 2004 LTD is a 1-channel, high-density, high-voltage isolator designed for reliable signal transmission. It consists of an infrared LED optically coupled with a high-voltage NPN silicon photo-Darlington. A key design feature is the integral base-emitter resistor, which serves to optimise switching speed and maintain stable performance under elevated temperature conditions.

Delivering robust electrical isolation, this device features an impressive isolation voltage of 3.75kV and a high minimum current transfer ratio (CTR) of 1000%. It supports a forward current of up to 50mA and boasts a high collector-emitter voltage of 300V. Furthermore, the component operates reliably across a wide temperature range from -55°C to +110°C, making it perfectly suited for demanding environments.
