Here is the datasheet that I have a question about. http://www.ixysic.com/home/pdfs.nsf/www/CPC1907B.pdf/$file/CPC1907B.pdf

It states in the Features List on first page. "Arc-Free With No Snubbing Circuits"

Does this mean that I do not need to add a Diode in reverse Parallel with my load? And it will be fine without it? I am driving an Inductive Load. 12VDC Motor Brake. 2-3amps.

There are no example circuits in Datasheet.

1 Answer 1


You should use the catch diode.

You must not exceed the absolute maximum blocking voltage stated in the datasheet (60V at 25 degrees C) and without a diode you will almost surely exceed that voltage when you switch off a solenoid load.

Also minimize the inductance of the wires running to the load (keep them together and minimize the length).
