Could any expert advise the transistor selection for switch purpose.
Should I choose BJT or MOS ? What's the character btw them for
switch purpose. Thanks.
In basic applications you can use both types of transistors BJTs and MOSFETs ..
However,
MOSFETs are gaining on BJTs in terms of new applications. They are faster and require less drive power, and low-voltage versions exhibit less on-resistance. Also, prices of low-voltage MOSFETs have dropped rapidly because of new designs and improved manufacturing techniques.
