Hello I design an electronic load, using IXTK200N10L2 power mosfets (T0264 package). I try to estimate the junction temperature of the mosfets, using an IR camera to measure accessible temperatures. Mosfets are directly mounted on a air-forced heatsink (Theta-sa around 0.08?C/W), with thermal grease. With the camera, I can access the temperatures of : - the heatsink near the mos...

I have a trick on-topic question, looking for possibilities for candidates for a 16-pin SMD device that has these pin outs identified so far: 1 & 16 - RC oscillator 4 - ground 7 & 8 - drivers for a "H" style MOSFet set of four transistors that between them generate a modified sine wave running at 60Hz and 120V. So it is NOT a TI SG3524/3525 chip. The MOSFets generate the pow...

Now i need a high-power T-R switch that can switch state in two microseconds. Drive outputs: +12 volts(current ,0.5 ampers) , +700 volts ,...

Now i need a high-power T-R switch that can switch state in two microseconds. Drive outputs: +12 volts(current ,0.5 ampers) , +700 volts , -12volts(-0.5 ampers), -12 volts. Tx path may stand 600 watts (peak). I want to use PIN driver IC,but don't find IC that may output +700 volt. So i have to design the switch by myself. I am going to employ discrete MOSFET as driver . Input to the ...

The RIS-797 project is for an isolated, programmable current-source charge-pulser, using the op-amp MOSFET techniques analyzed in x-Chapters 4x.26. This uses four 0.5pF isolator channels to run an I2C DAC and the current-source, including a range switch. Total output node capacitance to ground = 5pF, mostly due to DC-DC power-supply module. Two-terminal floating current sources...
