IS357 Description

Short technical summary and product information.

The IS357 from Isocom Components is an optically coupled isolator designed for signal transmission between systems of different potentials and impedances. It consists of an infrared light-emitting diode and an NPN silicon phototransistor housed in a space-efficient dual in-line plastic package.

 

Key electrical specifications include a minimum Current Transfer Ratio (CTR) of 50% at 5mA and a maximum Collector-emitter Saturation Voltage (Vce(sat)) of 200mV. The device offers a high isolation voltage of 3750Vrms and operates within a temperature range of -55°C to 100°C.

 

This optoisolator is suitable for applications such as computer terminals, industrial systems controllers, and measuring instruments. It is designed for surface mounting in a 4-SMD, Gull Wing package, facilitating high-density mounting.

 

The IS357 is a drop-in replacement for the Sharp PC357. All electrical parameters are 100% tested.
