Good Afternoon,
I am Aravind, working as a Project Associate at IIT Madras. Currently, I am working on a 36kW (peak power) project with 92VDC and 700Arms. Please help me to select MOSFET and gate driver for this application.

Hello,
I was wondering if the Co(tr) is also available for other FETs/Transistors than GaN and SiC.
Additionally, I was wondering if Co(tr) can also be used for voltage levels, which are different to the voltage level used to determine Co(tr). For example, Co(tr) was determined by loading the output capacitance from 0 to 500V, but the voltage level used is only 300V.
This is my understanding of Co(tr):
The fixed capacitance Co(tr) is used to capture the relationship between charge and voltage of the discontinuous output capacitance. Here, the equivalent capacitance Co(tr) is determined by charging the output capacitance at a current i and a voltage V, and thus describes the time-related effective output capacitance. Thus, Co(tr) can be used to determine the charge/discharge time of the output capacitance Coss independent of the topology.
Best regards

EVAL_1K4W_ZVS_FB_SMD,
I have no idea how to change the switching frequency ? pls hint
Thanks
AIMW120R035M1H
I am planning to use a 1200V SiC FET, "AIMW120R035M1H" to construct a full 4 FET bridge for 25kW usage.
But there is not a readily packed single gate driver that can deliver a minimum of 5A sink/source for 1200V SiC directly.
Is that means I need to find single >5A gate driver IC, or use two Half Bridge gate driver IC of >5A instead?
Please comment.

お客様はIRS2109Sから2ED2109S06Fへ置き換えを検討しています。
1.
2ED2109S06Fに関して、INとSDのInternal Pull-up/Pull-downの値を教えて下さい。
2.
2ED2109S06F Datasheetのp4のBlock Diagramでは、SDは+5VにPull-upされています。
この+5VとはVccのことですか?
もし、Vcc=12Vであれば、内部で12VにPull-upされますか?
お手数ですが、ご回答宜しくお願いします。
Show LessHi,
I am looking for a mosfet which would be appropriate for essentially DC switching of a 400V 7A continuous load. Low RDS on is preferred as I have limited ability to remove heat easily.

I'm currently using Mosfet IRL60SL216 trise in datasheet is only 180ns but when i use gate driver IR2110PBF, t rise measured is more than 1500ns as in picture, why is trise is so long, is datasheet or mosfet is fall?

Please advise us which OPN is recommended for New plan.
The selection sonditions are as follows.
・FET or SiCFET
・Around 600V
・DPAK, D2PAK that can be used for surface mounting
