https://www.dropbox.com/scl/fi/40slcbgbngggdcwwt95vi/Relay_Drivers.jpg?rlkey=gfai2trx0n6bnja2yl4 hber7i&raw=1 I like C1, with just a high-enough-voltage mosfet that it survives the max flyback voltage. C2 would use some exotic avalanche-rated thing. Everthing else needs more parts. Any more?

I was digging through le junque bocs yesterday looking for a TO-92 MOSFET, and found a bag of what I dimly remember as being such. But my memory is too dim, and I used a PN2222 with a base resistor instead. So before I throw these out, can anyone recognize the part? If I know what it is I can mark the bag and have it as a resource. Otherwise I'll probably trash it. It's a TO-92 ...

Here's a new section I'm hoping to complete, so it can be added to the x-Chapter book before it goes to the printer in a few weeks. Please look it over, but don't be too harsh, about its lack of mathematical vigor. It's closer to our usual back-of-the envelope approach to calculations. Fixes for errors, suggestions for clarification, improved accuracy, and comments welcome. ...

Some time ago James Arthur sent here a notification about the IMBF170R1K0M1XTMA1 SiC MOSFET. I have just re-prototyped one of my wide input range flybacks, and the results are excellent. The performance is comparable to the one with the 1700V C2M Cree part, but the converter's structure is much simpler, which is good for reliability. Thanks, James. Best regards, Piotr

I'm designing a power amplifier using some Exicon lateral MOSFETs as the final common-source stage. These will be used in various experimental systems. Each only needs to run around +/-50V out, up to 4A, and driving sinusoidally between 50 and 400kHz. The load can be approximated as a lossy series LC circuit, driven near resonance with R generally 10-20 ohms. There's an additional > 200

The idea is to turn on the mosfet for a while to heat up the darlington, then turn it off and take a few measurements as it cools down. A few points should be enough to calcula

Could some electronics guru please help ? I was running a SPICE simulation of an H bridge for an inverter, with 12 V DC input. The H bridge has PMOS on the high side and NMOS on the ground side. The switching works fine, and the output waveform looks exactly as it should, except that the amplitude is in the milliVolt range. I have adjusted the MOSFET sizes but that has not been very helpful. ...

I was looking to order some low current MOSFETs and realized all the popular items had thresholds of 3 volts and higher. I would like to use something that turns on pretty well at 3 volts so it won't need a 5 volt PSU. Any suggestions? I'm looking for a TO-92 case preferably but surface mount will be ok too. I could have sworn some years ago I tracked down a number of low threshold...

I'm looking for a small, inexpensive H-bridge, or full-bridge IC, including MOSFET switches, for a forward-converter application. (My old favorite HIP4080 series has 20 pins and requires external FETs.) Most of the ICs with internal switches that I've found are meant for driving motors, and seem to have slow switching speeds. 40 volts and 2 amps are my minimum requirements. The LMD18200 ...

Diamond buffers are kind of cool, emitter feedback makes them linear and they don't have much phase shift, but they kind of suck balls whenever you want to actually move appreciable current with them which unfortunately is exactly what you'd want to do with a buffer. I came up with this thing that uses a sort of MOSFET-BJT Sziklai pair input-thing to drive boosting transistors to pump m...

Suppose I have several rackmount boxes and each has a BNC connector on the back. Each of them has an open-drain mosfet, a weak pullup, and a lowpass filtered schmitt gate back into our FPGA. I can daisy-chain several boxes with BNC cables and tees. Each box has a 40 MHz VCXO and I want to phase-lock them, or at least time-align them to always be the same within a few microseconds, l...

This model for a PMOSFET shows VTO=1.00. The data sheet shows VGS(th) as -1.0 to -0.45 volts. I'm guess these are two different specs?

We've used transmission-line transformers to drive mosfet gates. We've wound them from micro-coax on ferrite toroids, with the shield being the primary and the inner conductor the secondary. Sub-ns speed and low leakage inductance. But it's labor intensive. So I was thinking about doing it on a multilayer PCB, like a 6-layer. Layers 1/3/5 could be one to three layers of spiral trace, pr...
