Are Computer PSUs Switch-Mode Power Supplies?
Modern desktop computer PSUs are regulated AC-DC switch-mode power supplies; they convert utility power into DC rails and are not electrical generators.
Power MOSFETs
Do MOSFETs Conduct in Both Directions?
A fully enhanced MOSFET channel can conduct current in either direction, but the intrinsic body diode makes blocking behavior directional when the device is off.

How to Protect a MOSFET When Switching Inductive Loads
Protect a MOSFET switching an inductive load by giving current a controlled turn-off path and coordinating clamp voltage, energy, layout, SOA, and thermal limits.

TVS or Zener for MOSFET Drain Protection?
Choose a TVS or Zener for MOSFET drain protection from pulse energy, clamp voltage, repetition, capacitance, tolerance, and the exact circuit topology—not the label alone.

How to Protect a MOSFET From Overcurrent
Protect a MOSFET from overcurrent with fast sensing and shutdown, a current-limited power path, coordinated fusing, thermal monitoring, and a defined retry policy.

How to Identify a Schottky Diode
Identify a Schottky diode by combining its full marking and data sheet with package pinout, circuit role, diode-mode behavior, capacitance, leakage, and rated voltage.

How to Connect Two Switching Power Supplies in Parallel
Parallel two switching power supplies only when their manufacturers permit it and provide a compatible current-share, droop-share, or redundancy method.
