[@yum33333]

Yeah, this video is pretty inaccurate. I'm guessing that "Electronoobs" doesn't really know anything substantial about this topic, because he completely misses out on the key differences between these devices. So, allow me: BJT: - CHEAP - Robust against static discharge which makes it very popular - High voltage capabilities (typ. 40-1000V) - Best low noise performance when used as a linear amplifier - When used as a saturating switch, poor turn-off behavior which limits the switching frequency to usually 20A) because the saturation voltage is roughly constant (usually .2-.5V), but... - Requires a high-current output control driver which makes it unpopular for high current applications - Current can only flow 1 way in the ON state, Collector->Emitter MOSFET: - Medium Cost - Extremely fragile to destruction by static discharge - Medium voltages (typ. 20-400V) - Poor performance in linear amplifiers (nonlinear behavior, high noise) - Extremely fast switching, easily up to 20MHz with high-power loads (and the new GaN FETs promise to be even faster) - Efficient for low-medium currents since it behaves like a low-valued resistor - Easy to drive since the gate is an open-circuit - Current can flow both ways through the device in the ON state IGBT (BJT with MOSFET gate): - High Cost - Fragile to destruction by static discharge (but usually less so compared to MOSFETs) - Very high voltage, up to 4000V - nobody uses these in linear amplifiers because it would be pointless - switching behavior is similar to BJT, but usually slower (Emitter So, the TLDR; is that you use BJTs for building robust interfaces since they usually don't need ESD protection, you use MOSFETs for low-medium current switches, and for really high-current switches you use IGBTs. The distinction between MOSFETs and IGBTs is basically on the basis of efficiency - the heat generated in a MOSFET increases as I^2 since it behaves like a resistor, whereas in a IGBT it increases more like Log[I]. You will have to do some math to figure out which transistor to use on a case-by-case basis. Hope this is more helpful to people than the video was.

[@CrisDFF30917]

Just great, I am studying engineering and its very important to understand that BJT can handle high voltages but low currents because when you try to use them with high currents the Saturation Voltage between Collector and Emitter increases and it implies higher power losses. MOSFETS can handle high currents once you apply around 12V to its Gate, but they have no reverse polarity protection and also can't handle high voltages, IGBTs are great for both purposes high voltage and high current but a disadvantage is that the C-E saturation voltage when you handle high currents increases and brings again higher power losses, well, perfection doesn't exist, right?

MOSFET is fine with high voltage as well. IRF840 can go up to 500V and I own few IXTF1N450 MOSFETs with a rating of 4500V and 0.9A (continuous Vds and Ids. They are incredibly expensive).

[@km5405]

from my internship at a company that designed and built power converters , a rule of thumb I came across is that around 1000V mosfets begin to lose out to IGBTS due to the tradeoff between voltage rating/impedance. ......sounds like a incredibly specialized mosfet. very cool! (and very expensive ;-) ).

[@sovietrepublic38]

@@km5405 True. The resistance of this MOSFET is very large compared to IGBTs with similar voltage rating. The main advantage is higher on-frequency.

[@sovietrepublic38]

@Mdmchannel Yes, 4500V. It's much larger then regular MOSFETs

These are what I got. I'm not an expert. Think about the current / voltage / switching time / leakage current you want. High voltage MOSFETs general have higher on-resistant. Take that 4500V MOSFET as example, the on-resistant is several hundreds of ohms but offers better switching time. If you don't care about switching time (for example, operating within 1000 Hz) but need high current, go for IGBTs. Read datasheets carefully when making your choice. You can find much more on Mouser website. You have to pay more if buying from Mouser. However, if you buy on Amazon, you risk buying recycled electronic components.

[@keshwin108]

Low ON losses will depend on the load current. Because some Mosfets have very low Rdson and the Collector emitter volt drop of and Igbt is around 1.2 Volts. So you should also calculate the conduction losses before deciding on Mosfet or igbt

The block graph was a perfect visual. thanks for this explanation!

[@bunkie2100]

MOSFETs are also used in audio amplifiers. In that application, they reduce the number of stages needed to get enough current gain to produce high power. One other way to look at the difference between BJTs (traditionally known as bipolar transistors) and MOSFETs is that BJTs have low-impedance inputs and MOSFETs have high impedance inputs. A typical BJT amplifier has a single voltage gain stage and two to three cascading transistor stages to achieve the required current gain. Typically, the MOSFET output stage can be driven directly by the voltage amplifier stage, much as it is done in tube amplifiers. The difference between tubes and MOSFET amps is that the output stage of a tube amp is low current, but very high voltage which is converted to a high-current, low-voltage signal by the output transformer.

[@hodissergiu8883]

Yes but an MOSFET based audio amp (class D) is only as good as the output filter and works for defined frequencies while an BJT (AB class amp) can work in a wider frequency region (while wasting more heat too). It depends on the performance wanted in the application

[@bunkie2100]

I was speaking of traditional class A or AB amplifier design. Class D is a completely different animal, essentially a pulse-width modulation approach.

[@bunkie2100]

And, to be completely clear, there is no requirement that a MOSFET amplifier has to be class D. They work just fine in class A and class AB. For many years I owned a Hafler DH-200 MOSFET class AB power amp.

Great beginner video. I would love to see you use each of these in 3 different circuits showing 3 real-world examples of their uses.

[@tylershepard4269]

For amplifiers, your best bet is to go with BJT’s, because they have very high transconductance. On the other hand, MOSFETS are nice because you can easily integrate digital control into analogue elements on the same IC, however, they do have poor transconductance. Over all, BJT’s are nice, but their performance (IE in a emitter coupled pair) is limited by thermal voltage. This is not true with MOSFET’s.

I am using Power Mosfets: IRFZ44N, IRF9510, IRF4905, IRF740. My question would be: - Do you need protection diode power Mosfets? Looking at the photo of the Mosfet (on the datasheet), the Mosfet has the built-in protection diode. But I'm not sure that is the case. Or if you want to say that ... If anyone knows, I would be very grateful ... thanks and greetings to all ✋
