Questions answered in these manuals
How can the drain pin voltage limit be extended?
The drain pin voltage limit can be extended beyond 100V by adding a Zener clamp and using a series limiting resistor.

What component limits the current for the Zener clamp?
A series resistor, typically 2k, provides current limiting for the Zener clamp.

How do ideal diodes protect against wiring errors?
They provide protection similar to discrete diode solutions, making wiring errors transparent to the load or preventing damage through reverse input protection networks.

What happens if RTNA and NEGA are swapped?
The associated ideal diodes become reverse biased, making the wiring error transparent to the load while the other battery provides power.
