What is the normal working state of a voltage regulator diode? How to measure good or bad?
What is the normal working state of a voltage regulator diode? How to measure good or bad?

When the voltage regulator is working normally, it is in a reverse breakdown state, and this interval is recoverable. Don't mistakenly think that seeing the word 'breakdown' means the device is damaged.

Reasons and inspection methods for damage of rectifier diodes
Reasons and inspection methods for damage of rectifier diodes

A rectifier diode is a semiconductor device that can convert alternating current energy into direct current energy. It has unidirectional conductivity and usually includes a PN junction with two terminals, positive and negative. Current can only flow in from the positive terminal and out from the negative terminal.

MOSFET Devices - Subthreshold Swing (STS) Detailed Explanation
MOSFET Devices - Subthreshold Swing (STS) Detailed Explanation

The subthreshold swing is a performance indicator that measures the rate of transition between the on and off states of a transistor. It represents the amount of change in gate voltage required for the source drain current to change tenfold, also known as the S factor. The smaller the S, the faster the on/off rate.

How to choose the best switch mode DC-DC converter?
How to choose the best switch mode DC-DC converter?

By utilizing the energy storage characteristics of capacitors and inductors, high-frequency switching is performed through controllable switches (MOSFETs, etc.) to store input electrical energy in capacitors (inductors). When the switch is turned off, the electrical energy is released back to the load, providing energy as a switching power supply. The ability of its output power or voltage is related to the duty cycle (the ratio of the switch conduction time to the entire switch period). Switchi
