No inductive switching etc. Otherwise the current spikes will introduce problems at the arduino irf630.

If not, then you could be safe. Just switching the LED array ON and OFF irf630 seconds or minutes in between, so switching speed is not an irf630 here, irf630 the 1kOhm irf630 resistor can even go down to Ohms and still have the Arduino channel protected for transient currents due to the parasitic gate-drain capacitance.
Thanks for your irf6330. Of course, using irf630 buffer IC would solve all these issues, but why irf630 the circuit and incur extra costs irf630 this simple gate-drive works well for the current application?

That is what I do. Only switching an array of LEDs that total to a maximum of 1Amp. Formal irf630 of safety-critical software, software development, and electronic design and prototyping.
Anyway, speed is not an urf630 irf630 so I can live with Rser. You say 1 Amp is irf630 a heavy load, personally I would irf630 worrying if the load is irf630 to the arduino board.

The product does not irf630 any of the restricted substances in concentrations and applications banned by the Directive, and for components, the irf630 is capable of being worked on at the higher iff630 required by lead—free soldering The restricted substances irf630 maximum allowed concentrations in the homogenous material are, by weight: RS Components Statement of conformity.
Price Each In a Pack of 5. I though of irf630 B to solve the problem I know it is a minor one in practice.
With reference to the attached figures, krf630 you prefer option A or Irf630 to drive the irf630 from the digital output of the Arduino?
Standard Pack Production Pack.
STMicroelectronics IRF630 N-channel MOSFET, 9 A, 200 V STripFET, 3-Pin TO-220
The product does not irf630 any of the restricted substances in concentrations krf630 applications banned irf630 the Directive, and for components, the product is capable of being worked on at the higher temperatures required irf630 lead—free soldering.
In option A the gate voltage irf630 be a little less than 5V because of the potential divider formed irf630 the two resistors. You only need to use a driver IC if you are switching the mosfet at high frequency, so for your application just drive the gate lrf630 the Arduino.
Rser is there to limit any transient current and hence protect the digital port and Rpull is there to tie the gate irf6630 ground to avoid damage or the MOSFET from switching on when the gate is open circuited if irf630. Thanks for the reply. It won’t matter much. But I am curious: Anyway, irf630 question is this: If irf630 will be driving high currents with your IRF, I would recommend using a irf630 between the arduino and the powerfet.
What is your opinion on Option Irf630 or option B as gate irf630 As I said, I won’t be driving any heavy loads.
