Specifications for Roadmaster Diodes # RM-690 and # RM-790 for Use on a Semi-Trailer

Question:

I am interested in the RM-790 and RM-690 Diodes that you sell. Do you have prints and specifications for these diodes? My application is for battery isolation for a 25A fused circuit on a semi-trailer. I need to assure the diodes will withstand 35 amps continuous and how much heat they will generate, what the physical size is, what is the environmental capability need -40F to 150F .

I do have some technical information for you about the Roadmaster Diodes # RM-690 and # RM-790, but I do not have any prints available.

Both part numbers are 1/2" tall, 1-9/16" wide, and are 1-5/16" long. They can withstand up to 85 of continuous amps, plus they have been tested to work when they are frozen and tested in an oven up to 180 C without failing.

My contact at Roadmaster said that these can definitely take a beating and will work great for your application.
