Paralleling mosfets to reduce Rds On?

This if a fairly simple question. I have some APT43M60L MOSFETs with a fairly high on resistance. They get quite hot and waste a lot of power in my induction heater. They work great but get really hot ...

Dual N-channel mosfet Rdson value

I'm going though datasheets of some dual N-channel MOSFETs for li-ion battery protection, like 8205A or ECH8695R, for some thermal and power dissipation calculations. There are Rds(on) values, like ...

Help needed in understanding MOSFET datasheet

I am trying to find a logic level MOSFET for 3.3V operation. In my case, I am trying to compare AOD510 & AO4402. AOD510: \$\mathrm{R_{DS(on)}}\$ @ 4.5 \$\mathrm{V_{GS}}\$ = 0.004 ohm but has no ...

Vds vs. Rds(on) on 19N10L mosfet

I measure in common source connected mosfet (19N10L) Vds about 2.4V in on state. The current is 2A. In datasheet is defined Rds 0.1ohm. Why is Vds in this mosfet so high (2.4V)? Shouldnt be Vds = 0.1 ...

What is the parasitic resistance due to an IC package in a mosfet? (or any package)

How much resistance does the package of an IC contribute to the paraistic resitance of a circuit? (most applicable to mosfets)
