A 60A MOSFET transistor for smooth power control
The counterpart of the NPN transistor, here is the MOSFET Channel N, a power transistor. We have the famous STP16NF06 (16A) is sometimes not enough... especially if the temperature rises.
This FDP7030BL transistor has an RDS(on) (Drain-Source) resistance of less than 0.01 Ohms, it will be able to drive really high currents while limiting heat dissipation (which is very interesting).
The other interesting point of this transistor is that it has a gate voltage (Vgs(th) for Gate Threasold Voltage) of 1.9V, which allows it to be used directly with 5V microcontrollers. It is not excluded to be able to test it with 3.3v peripherals... but it depends on the effective switching voltage of the transistor in your hands (it varies significantly from one batch to another), if the latter is closer to 2V it will work without problem.
Using a Channel-N is practical and widespread... as for NPN transistors, the MOSFET Channel N is more common than the use of the channel P (equivalent to the PNP).
The FDP7030BL model will be an excellent challenger if you realize that your STP16NF06 are suffering and cracking... MOSFET transistors are very popular among hobbyists because they are able to withstand very high currents (practical for controlling motors but also of LED strips).
As a suggestion, we can propose you 100 KOhms resistors (see below in our tutorial section)
- 2 x MOSFET Channel-N - FDP7030BL
- FDP7030BL data sheet.
- Drain Source Voltage Vds: 30V
- On Resistance Rds(on): 0.009ohm
- Max Operating temperature: 175°C
- Pd dissipation power: 65W
- Rds(on) Test Voltage Vgs: 10V
- Threshold Voltage Vgs: 1.9V
- Our tutorial on "Mini Hobbyist Motor Kit" which implements the STP16NF06, you can replace the STP16NF06 with an FDP7030BL (which has the same pinout).
Afterwards, the use of a motor with a power MOSFET will be really... "trivial".
- As soon as we have the opportunity, we will also present an assembly to order an LED strip.
- Cool your transistors, they don't like to get hot!
- The maximum current of an FDP7030BL goes from 60Amp, this is a very high current. So chill it ;-)
- Using a High Frequency signal to control a transistor causes an over-rise in temperature during its operation (this rise can be significant!).
- Going from 0 to 1 is the equivalent of an "infinite frequency" for a very, very short period of time.
No problem if it's once in a while...but it will become significant (cause significant overheating) if it happens often...which is the case if you're using a PWM signal to modulate the output power of your transistor.
Again... cool your transistors.
