H11G2 Description

Short technical summary and product information.

The H11G2 by QTC is a high-gain NPN Darlington optocoupler housed in a standard 6-pin DIP package. It is engineered for efficient signal transfer in demanding applications requiring fast switching and high output gain.

 

Key electrical specifications include a high collector-emitter voltage of up to 80V for the H11G2, and a maximum isolation voltage of 5000VRMS. The device operates across a wide temperature range of -55°C to +100°C, ensuring reliability in various environments. The minimum current transfer ratio (CTR) is 1000% at IF=10mA, VCE=1.2V.

 

Applications for the H11G2 series include modems, copiers, facsimiles, and numerical machines, particularly for signal transmission between systems of different potentials and impedances. The integral base resistor optimizes speed and performance, while the external base lead offers additional flexibility.

 

This optocoupler is mounted via through-hole soldering. It is available with options for VDE approval, 10mm lead spacing, and surface mount packaging.
