Okay, let’s talk about this whole MOSFET SiC thing. I wanted to mess around with some new tech, you know, see what all the fuss was about. So I got my hands on some of these silicon carbide MOSFETs. I’d heard they were supposed to be way better than the regular silicon ones, faster switching, less power loss, all that good stuff.

First, I grabbed a couple of these SiC MOSFETs from a friend. These things aren’t cheap, so I was pretty careful with them. They feel solid, you know, like they are made well.
Then, I set up a simple test circuit. I just wanted to see how these things behave compared to the regular MOSFETs I usually use. Nothing fancy, just a basic switching circuit with a power supply, a resistor, and the MOSFET. I hooked up my oscilloscope to measure the voltage and current, you know, the usual stuff.
I double-checked all the connections. You don’t want to mess up with this stuff, especially when you’re dealing with higher voltages.
Get Down to It
- I started with a low voltage, just to be safe. I flipped the switch, and boom, the SiC MOSFET turned on like a champ. The switching was noticeably faster. Like, way faster. I increased the voltage a bit, and it still performed great.
- I swapped out the SiC MOSFET for a regular silicon one, just to compare. The regular one was definitely slower. It’s like comparing a sports car to an old sedan. There was also more heat coming off the regular MOSFET. Not a ton, but noticeable.
- After a little bit test, I really pushed the SiC MOSFET, cranking up the voltage and the switching frequency. This thing didn’t even break a sweat. It switched fast, stayed cool.
Honestly, I was pretty impressed. These SiC MOSFETs are the real deal. They live up to the hype. I can see why people are excited about them, especially for things like electric vehicles and power supplies. I am definitely going to use these in my future projects, the efficiency gains alone are worth it. This little experiment totally convinced me.

I spent hours playing around with it, it is really amazing. I can’t wait to use it in a real project. Finally, I shut down the power and packed my tools.
Anyway, that’s my little adventure with SiC MOSFETs. If you get a chance, check them out. They’re pretty cool.
