Hefty, good mounting hardware and solid construction. Used to repair an old style battery charger that used several much smaller diodes.

worked fine - burnt out on surge

Can't handle 30 amps 12 volts so I don't know where the 75 amp rating came from. It got so hot you can't touch it after 5 second and .89v voltage drop across the diode at 20-30 amp and .23 no load and 13 amp 12 volt it's got hot after 15 second and .78v voltage drop.I am glad didn't buy more than one. it does work as a diode

Used this diode as part of a windshield wiper park function. 1983 Chevrolet chassis, wiring harness and wiper motor (with internal park switch which is grounded in the park position) used for 1948 Chevrolet truck. Used original wiper switch from 48, losing the original column switch (which was integral to the park function). Removed IGN voltage going to wiper motor park switch. Fed that park switch by wiper switch function, and placed diode on exiting park wire to prevent grounding fault.

It works, drops output by just a hair but still works well. I tried it on my solar kit, failed. Voltage dropped and confused the solar charger. Now I use in 24 volt alternator to the battery pack directly. It works.... Watch your amps also.. Mine got warm around 75amp mark.

would have been better if it included an installation insulation kit, very hard to fide. work fine but hard to install without the insulation kit.

The diodes ok but the stud nuts were not the correct threads. Real sloppy and if tightened for best cooling of the diode it would strip the threads. I tried to find a metric nut that correctly fit the studs but without success. I'm not sure what type of thread was used on these. As a result I would not purchase any more of these diodes.Richard Heiss

A diode in your solar panel wiring will prevent your batteries from discharging back into your solar panel at night. It's like a "ONE-WAY" electrical Valve. It allows your batteries to charge when the sun is shining and blocks your batteries from sending the DC voltage back to the solar panel during darkness and dark, cloudy days. Most panels are a lot lower than 75 amps but these 75 amp diodes will allow youi a little room for error. If you have a short circuit; your system fuse will probably protect the expensive diode from overcurrent. You install it between the solar panel POSITIVE wire BEFORE it goes into your Charge controller. The polarity of the diode is most-important. When you connect the positive wire from the panel to the diode; connect it to the "TIP" and then connect the "Bolt" side of the diode to the POSITIVE terminal on your charge controller. If you install it backwards, the solar panel will be blocked from charging your batteries. Use a separate diode for each panel in your system UNLESS the panels already have blocking diode installed. Some do/some don't. Check the paperwork.
