Toshiba adds four-pin SiC mosfet to cut losses

“Units within the TWxxxZxxxC sequence are the primary Toshiba SiC merchandise to be housed in a TO-247-4L(X) package deal with a fourth pin,” in keeping with the corporate. “This enables the availability of a Kelvin connection of the sign supply terminal for the gate drive, thereby lowering the parasitic inductance results of the interior supply wire and bettering high-speed switching efficiency.”

Deciding on the brand new TW045Z120C, it's mentioned to have ~40% higher turn-on loss and ~34% turn-off loss in contrast with its present three-pin TO-247 TW045N120C.

Inside TWxxxZxxxC, there are 5 650V and 5 1200V mosfets, with typical drain-source on-resistance starting from 15mΩ to 140mΩ. “Mixed with low gate-drain cost values, it's going to allow low losses even in excessive frequency purposes,” is claimed. Most steady drain currents inside the household is 100A.

Swap-on with three or 4 pin packages (800Vdd, 20A Id, 0-18Vgs, 4.7Ω Rg, 25°C, 100μH load)

Choosing the 1.2kV TW045Z120C talked about, this can be a 40A (25°C, 30A steady or 82A pulsed at 100°C), 45mΩtyp (67mΩtyp 150°C) system.

Gate drain cost is 8.9nC, gate-source cost is 21nC, and whole gate cost is 57nC.

And switching off

Reverse restoration cost and time are 297nC and 54ns, with a present peak of 11A (800V, 13A, 1kA/μs, Vg=0V).

The package deal is rated for as much as 182W and the channel can run as much as 175°C – channel to case resistance is 0.824°C/W.

Industrial switching PSU purposes are foreseen for the household, in servers, information centres, electrical car chargers, photovoltaic inverters and uninterruptible provides.
