PC357NT Description

Short technical summary and product information.

The PC357N Series from Cosmo is a general-purpose photocoupler featuring a 4-pin Mini-flat package. It contains an IRED optically coupled to a phototransistor, providing an input-output isolation voltage of 3.75kV(rms).

 

Key electrical specifications include a high collector-emitter voltage (VCEO) of 80V and a minimum current transfer ratio (CTR) of 50% at an input current of 5mA. The CTR can range from 50% to 600% at 5mA input current. The package is a double transfer mold type, making it suitable for flow soldering processes.

 

This photocoupler is designed for applications requiring high density mounting, such as programmable controllers. The Mini-flat package is ideal for space-constrained designs.

 

The PC357N Series is recognized by UL1577 for double protection isolation. The package resin meets UL flammability grade 94V-0.
