MCA255 Description

Short technical summary and product information.

The QTC MCA255 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 photodarlington in a space-efficient dual in-line plastic package.

 

Key electrical specifications include a high isolation voltage of 5300Vrms (7500Vpk) and a minimum current transfer ratio of 100% at 5mA forward current and 5V collector-emitter voltage. The device operates over a temperature range of -55°C to 100°C, with a maximum total power dissipation of 250mW.

 

This optocoupler is suitable for applications such as computer terminals, industrial systems controllers, and measuring instruments. It is available in a DIP-6 package suitable for through-hole mounting.

 

Absolute maximum ratings include a forward current of 60mA and a reverse voltage of 5V for the input diode. The output transistor has a collector-emitter breakdown voltage of 55V. All electrical parameters are 100% tested.
