Hi, I would like to use the SMF26CA as voltage suppressor for a 24VDC bi-direction motor, max current @3.5A. Is this Zenor diode will be enough for the application and how do I connect the diodes into terminal blocks, is there a holder or some kind of adaptor to do the job?
Welcome to the Digi-Key TechForum xiaolei2000.
The SMF26CA can handle 4.8A of current, so it will be able to handle the 3.5A of your motor.
This surface mount diode is less than 1/8" long. We do not have a holder for this device.
Best way for mounting in a terminal block, is to find a comparable part with wire leads.
Click here for 5KP26CALFCT-ND. This is the closest match I found to the Standoff, Breakdown and Clamping voltages. It can handle a lot higher current than the original diode. Please check the specs and the datasheet for compatibility to your application.
Hi @xiaolei2000 ,
Here are some other accessories that may help mount the above diode:
Otherwise, this resource goes over a few DIN rail protection technologies and uses.
2946-280-502/281-609-ND is an example of a 24v DIN mount terminal with surge protector.
Thanks a lot for your replies!
