field effect transistor 2

2. Precautions for use: (1) When storing MOS devices, the three short-circuit terminals should be placed in a shielded metal box or packaged with tin foil.diode

(2) The extracted MOS devices cannot slide on the plastic board, and should be stored in metal trays for future use.

(3) The soldering iron used for welding must be well grounded or disconnected from the power supply and used for residual heat welding.diode

(4) Before soldering, the power and ground wires of the circuit board should be short circuited and separated after the MOS devices are soldered.

(5) The soldering sequence of each pin of MOS devices is drain, source, and gate. The order of disassembly is reversed.

(6) It is not possible to use a multimeter to measure the poles of MOS transistors. Testing MOS transistors requires the use of a tester.

(7) It is best to connect a protective diode to the gate of a MOSFET under permissible conditions.

(8) When using MOS transistors, special attention should be paid to protecting the gate (it should not be suspended at any time).
