Bjt vs mosfet as switch

WebFeb 27, 2024 · The Bipolar Junction Transistor (BJT) is a current-driven device (in contrast, MOSFET is voltage-driven) that is widely used as an amplifier, oscillator, or switch, amongst other things. A BJT has three pins – the base, collector, and emitter – and two junctions: a p-junction and n-junction. There are two types of BJT – PNP and NPN. WebMay 14, 2024 · BJT can switch faster than MOSFET due to the less capacitance at the control pin. However MOSFET is more tolerant to heat (stable to thermal changes) and can simulate a good resistor.”. So, to answer your question, a “BJT can switch faster than MOSFET due to [there being] less capacitance at the control pin.”.

WebMay 9, 2024 · MOSFET in saturation region is preferred to make it work as a switch. It's because it's written by someone who thinks that the name of the equivalent section of the BJT's characteristic is 100% transferable to MOSFETs. To clear this up: - When a MOSFET is operated as an on -switch it works in the triode or ohmic region WebTransistors (such as Bipolar Junction Transistors (BJT)) are solid state switchers, that is, they don't have any moving parts. Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFET) are also transistors, but are voltage controlled, whereas classical BJTs are current-controlled. Relays are more expensive, but they have moving parts.

WebBJTs are much more suitable than MOSFETs for driving low-power LEDs and similar devices from MCUs.
