MCIGICM 20Pcs 15SQ045 Schottky,15amp Diode Axial Schottky Blocking Diodes

Great price. Work in my application in automotive to stop back feed in the reverse light circuit.

Great items. Great value

Sand the edges down and ready to solder I haven't tested it's abilities yet but I do know it conducts electricity the one way

Good, build quality and nice thick wire ends, the diode is a little bigger than I was expecting, but it has held the amperage. I am passing through, 3 A at 12 V.

Added heat shrink to the leads and used a lever lock for a quick and re-Configurable circuit. The configuration is for providing a door open power signal (12VDC) and accessory bus power to accent lighting circuit without one bus powering the other. The diodes block one bus from powering the other bus. The accent LED lighting is illuminated when the door is opened and stays on after the ignition key is in the "Accessory" or "Run" position. Without the diodes this circuit would not be possible. Lighting comes in on the yellow wire when the vehicle door is open. Accessory bus power comes in on the red wire when the ignition key is in "Accessory" or "Run". The accent lighting circuit is powered when either of the two sources are powered. These diodes can handle 15 amps so that's more than enough for LED accent lighting in a vehicle. Pickup truck in this case.

While the diodes do work well, I question if they really can handle the rated 15amp's claimed. They are not all that big, but I'd be leery about putting the 15A through them as they are not the size I'm used to at that amount of current. As can be seen, I did not deduct any stars because this is simply just a hunch and an unproven fact.

Okay not a big electrical guy here, just needed something to prevent a backfeed on a trailer application. Now my third brakelight blinks when my turn signals do gaining more attention to the trailer

The coil on a 20HP garden tractor with a Kohler K532S engine needs power when the ignition switch is in the on and starting positions. The coil had power in the on position but not while attempting to start the engine. So, I put a diode between the wire that goes to the starter and coil. This sends power to the coil while the ignition is in the start position but will not allow the power to go from the coil to the starter when the ignition is in the on position. I'm very satisfied with the diode.
