LV isolation reverse bias
HV isolation reverse bias
Voltage drop across diode all cases
Thermals (shouldn't be anything significant)
The following will outline my testing of the ideal diode:
I populated everything as instructed above
I first wanted to ensure the forward bias works. The following table outlines the drop across (everything without load btw) the diode based on the output and input. Note, the table only has forward bias testing, where no power supply was loaded onto the cathode.

The ideal diode works!! that was the smoothest validation so far → ideally id test with higher potentials, but considering that this testing was above the rating of the zener diodes already, it’s safe to say it operates as intended. Of course, double checking with a potential of over 100V would be ideal before integration testing (in which case I can finish filling out these tables).
The following will outline my testing of the relay and relay driver:
I have populated everything necessary and rerouted the relay as per the schematic issue of placing it low side instead of high side.
When I toggle a GPIO for enabling the DRV120APWR, I notice that if it is a low or a high value of GPIO, the contacts on the relay still close. Need to still investigate this, but it seems like the relay is always pulling the output low. This is also probably a fault with the rerouting because it seems to just turn on no matter the code and just when 12V is present. Also, the LED doesnt ever turn on.
I can also hear a high pitch hum as noise from the driver → might want to adjust the resistor/cap to adjust the PWM.
