For home automation I want to switch some DC current ranging from 0-60v.
Some 48v led series, strike plates, and allot more.
I want to build some universal switching boards that I can use for all DC switching that I need.
It needs to switch fast enough to use PWM from an Arduino pin. And works perfect on 4-5v.
For 220v AC I will use solid state relays (ebay.com).
I ones used a mosfet IRF540N (old one) for switching fans and leds, but I want to choose the best available, and also more watts.
Someone advised me this one...
IRLZ34NPBF rom International Rectifier
55V, 30A, max.68W
Rds On (Max) @ Id, Vgs: 35 mOhm @ 16A, 10V
Vgs(th) (Max) @ Id: 2V @ 250µA
Gate Charge (Qg) @ Vgs: 25nC @ 5V
Input Capacitance (Ciss) @ Vds: 880pF @ 25V
But the 68Watt is a little low, I would like a heavy mosfet.
On Digikey I see lots of heavy mosfets, But I'am not sure if they work wel with an arduino pin/5v. Or if they switch fast enough for PWM?
I selected some...
STP60NF10 from STMicroelectronics
100V, 80A, max.300W
Rds On (Max) @ Id, Vgs: 23 mOhm @ 40A, 10V
Vgs(th) (Max) @ Id: 4V @ 250µA
Gate Charge (Qg) @ Vgs: 104nC @ 10V
Input Capacitance (Ciss) @ Vds: 4270pF @ 25V
or
IRLB3036PBF-ND from International Rectifier
60V, 195A, max.380W
Rds On (Max) @ Id, Vgs: 2.4 mOhm @ 165A, 10V
Vgs(th) (Max) @ Id: 2.5V @ 250µA
Gate Charge (Qg) @ Vgs: 140nC @ 4.5V
Input Capacitance (Ciss) @ Vds: 11210pF @ 50V
or
IRL3705NPBF from International Rectifier
55V, 89A, max.170W
Rds On (Max) @ Id, Vgs: 10 mOhm @ 46A, 10V
Vgs(th) (Max) @ Id: 2V @ 250µA
Gate Charge (Qg) @ Vgs: 98nC @ 5V
Input Capacitance (Ciss) @ Vds: 3600pF @ 25V
I will use a small transistor on the pins so it can give more than 20mA. But will these heavy mosfets work?
What are the disadventages of these heavy mosfets, I don't know allot about mosfets, Don't know anything about those 4 lines of specs like RDS, VGs, Qg or CISS.
