WebJan 11, 2024 · The MOSFET will have less IR drop when 'on' (only Rds (on)) than a BJT (Vce (sat)). Also, the BJT has base current, while FET gate current is essentially zero. … WebThe 1N4007 diode can be used for the reverse battery protection. The 1N4007 diode has a voltage drop of around 0.7 V and maximum forward current of 1A. Fig. 2: Circuit Diagram of IN4007 based Reverse Battery Protection. During the experiment a 3.7 V Li-ion battery is used which can provide 3.3 V supply voltage.
WebMOSFETs are voltage controlled devices and BJTs are current controlled devices. There are many examples of mostly equivalent circuits using either. Usually a designer picks … WebA BJT gate on the other hand "looks" a lot more like a diode, rather than a capacitor. Not quite. They both control currents, but you are right on the current vs. voltage control. An ideal BJT is a current controlled current source and and ideal MOSFET is a voltage controlled current source.

WebMar 30, 2024 · The output of the low V CE (sat) BJT Q3 is shown below. The source voltage is 5V and the output voltage on the load is nearly 4.958V that is much higher than 4.8V out of a standard PNP BJT. Assuming the load current is 125 mA, we can reduce the power dissipation by the switch by about 20 mW when a low V CE (sat) transistor is used.
