More on the TI chip, being sold on ebay for a fiver...
"You could connect them any way as long as your method can take the rated current. As follows.
1/ As you say soldered directly to a purpose made PCB
2/ Connect wires by soldering to the leads and then to the tags.
3/ Use crimp connectors straight onto the leads. Make sure they are well crimped (ie. No sign of movement on the lead). A poor crimp can lead to hotspots and failure/fire/damage to surroundings.
Note. In all circumstances:
1/ Be careful not to exert pressure on the lead/package interface during connection. This could damage the device.
2/ Do not overheat the leads during soldering, this could permanently damage the internal circuit.
3/ Use a connecting method that can handle the very high forward current.
IPC-620 regulations describe electrical interface methods that should be employed.
Regarding your intended use I really can't advise whether it will work or whether it work or whether it could cause damage. Please read the Texas Instruments data sheet"https://www.ti.com/lit/ds/symlink/sm74611.pdf" online
Remember that internally, these are not actually built as a Recifier diode. They are a hybrid equivalent and as such they do have an inate instability. This is because when passing current, the internal circuitry turns off for a very short period, about 2 to 3 ms. During this period, the forward voltage drop increases to to about 0.6V due to the internal parallel Schottky rectifier. Whether or not your car could be affected by this I don't know, since they were designed for Solar cell and power supply purposes. So any other use is carried out at your own risk.
And additionally. These can probably not be used as a Back EMF clamping diode, since the reverse voltage may be too high.
As I suggested, please read the manufacturer's data sheet to decide if these are suitable for your intended use".
