- FET
broader category; all MOSFETs are FETs, but not all FETs are MOSFETs
- insulated-gate field-effect transistor
full technical name; very formal, rarely used in everyday engineering talk
用法筆記
Frequently written in uppercase as MOSFET. The lowercase form mosfet is also accepted in informal technical writing. The abbreviation expands to 'metal-oxide-semiconductor field-effect transistor', though engineers almost always use the shorter form.
