IS281GB Description

Short technical summary and product information.

The Isocom Components IS281GB is an optocoupler designed for signal transmission between systems of different potentials and impedances. It features an infrared emitting diode optically coupled to an NPN silicon photo transistor.

 

Key electrical specifications include a high AC isolation voltage of 3750VRMS and a wide operating temperature range from -55°C to 110°C. The current transfer ratio (CTR) selections are available, with a minimum of 100% and a maximum of 600% at IF=5mA, VCE=5V. The collector-emitter saturation voltage (Vce(sat)) is a maximum of 200mV.

 

This optocoupler is suitable for applications such as switching mode power supplies, industrial system controllers, and measuring instruments. It is housed in a 4-SOIC package and utilizes surface mount technology.

 

The device is Pb Free and RoHS Compliant. It is available in tape and reel packaging with 1000 pieces per reel.
