His solution is to add a P channel MOSFET which only allows power to flow when the polarity of the source voltage is correct. The schematic above shows the P-FET on the high side of the circuit.

Since the temperature measurement must be done over the same line and against ground, the MOSFET has to be placed between the supply voltage and the heater (high-side switch). A P-Channel MOSFET is ...

if you use a P-Channel MOSFET, switch to common power. If you're not sure what you have, consult the datasheet for your transistor. In my schematic, I'm using a Yellow wire to represent the 12v power ...

The Rutronik portfolio for power transistors includes the power MOSFETs from YAGEO XSemi ... 700V drain-source voltage with up to 300A leakage current, VGS at 10 V4. The P-Channel provides 20V to 700V ...

"Successful deployment of next-generation LEO satellite constellations and other space-ready systems require radiation-tolerant discretes and ICs with lead times and production volumes that enable ...
