D2 is a 18V Zener, LM3Z18VT1, diode. M1 is a NCE01P30K. Node DO is 8V by default and 0V when the circuit activates.
If M2 in the circuit below opens, what is the voltage at the gate of M1? Now because there is no current flow through M2 I would assume that M1's gate would 18V due to the Zener. But something doesn't seem right here. Any help is greatly appreciated.
Thank you for your time.
