I need to switch some LED's via a PIC.
I chose this Mosfet IRLML2060TRPBF
Data attached.
Like to know if these MOSFET is good to switch less than 1Amp LED loads with a 5V Logic without a sink.

 

With Vgs=4.5V the Rds(on) is 640mV, so at 1A current it would dissipate 640mW. That's close to the 800mW absolute maximum power allowed at a temperature of 70C, so you'd be sailing too close to the wind IMO. I'd be looking for a FET with a lower Rds(on).

 

Any Suggestions ?

 

Digikey says this part is a logic level FET.
What do you say to this part.

 

How about this ?
Too bad they don't come in smaller package

 

I generally tend to use the IRL540 with a Pic.
Max.

Marginal...uncertain.

 

Marginal...uncertain.

Thought so too.

Any suggestions on a smaller package of IRL540

 

Found something better.
BUK139-50DL
What do you think ?

Is it good for driving LEDs in PWM ?

That device has a very slow operate times (in the tens to over a hundred microseconds, see data sheet, pg.4) so may not be suitable for a PWM application.
What is you PWM frequency?
Have you looked at these?

 

PWM is like LED dimming. Fade in and out

 

How's this for 1Amp LED PWM fading through a PIC

 

That looks ok.

 

Thanks Alec_t
Any one else care to confirm.
Few votes and I will place the order.

 

I second the motion.

 

I bought BUK98150-55A and look what I got. Are they the same thing ?

 

See page 2 section 7 of the datasheet.. (Marking)..

 

Yup.
According to the NXP datasheeet :-

Type: BUK98150-55/CU
Marking code: 915055

 

Thanks.
That is a relief.

It's rather frustrating that a manufacturer would put a code on the package that's unrelated to the part designation.
