What Is A Transistor?
A transistor is an electronic semiconductor device that controls the flow of a large electric current using a smaller current. The flow of the larger current correlates with the small current, effectively making a transistor an amplifier.
MOSFET is an acronym that means: Metal-Oxide-Semiconductor Field-Effect Transistor.
BJT is an acronym that means: Bipolar Junction Transistor.
Common Transistor Applications Include (but are not limited to):
- Audio amplifiers.
- Signal amplifiers.
- LED dimmers.
- PWM motor controllers.
- AC to DC power inverters.
- HVAC inverter-drive systems (VRF).
- Controlling large industrial relays using microcontrollers or other discrete electronics operating in the microamp (μA) range.
