What is this triple-transistor arrangement called?
For an old Fuji 2DI200D-100 power transistor module, it uses three transistors internally for each half-bridge:
The circuit in question doesn't connect to the middle bases at all, just B1 and B2, so this (dual) triplet is being used solely as two…

What's the optimal way to drive a 2DI50D-100 power module?
I've been messing around for a couple days with this 2DI50D-100 power module that I got out of an old Italian VFD that I got dismissed at work (I'm an electrician) because it stopped working.
This is the schematic that's attached to the device…

USB 5V and 5V AC/DC Power Module protection needed?
Im designing a small board that with have an input 220VAC and with an AC/DC module will generate the 5V for my 5V components and then with a regulator I generate 3.3V for my 3V3 components.
There will be also and a usb to uart interface for…

Collector current in datasheet Graphs
Here is an example of output characteristics fot IGBT devices, i.e., the "collector current (Ic)-to-collector emitter voltage (Vce)" graph. Can somebody help me find what Ic represents here? I mean, is Ic the average, rms, or something else?
If it…

Proper 5vdc relay module hookup
I've been thinking about this for awhile so I might as well post the question here and see if anyone knows the answer to it.
I have this type of relay module:
So my question about this relay is:
1) Use the ground wire to the (in)NO->COM(out) for…

How to determine maximum switching frequency of power modules?
Power IGBT and MOSFET modules give some datasheet values that look like they could be used to calculate a maximum frequency, but I'm not sure how to interpret them to do so.
The datasheets generally have four timing parameters: turn-on delay time…

Power module 5VDC to 5VDC is not working in the PCB
In my PCB, I am using 2 DC-DC power modules B0505S-1WR3 and B0512S-1WR3. The power module B0512S-1WR3 is working as expected with output voltage 12V when activated. But B0505S-1WR3 is having a problem, it is not giving any output when switched on. I…

Current sinking in a DC-DC module
If I connect two DC-DC Modules (example module in the figure below) in parallel, can I increase its current capacity?
Also, I have another doubt out of curiosity. If I connect a module in the following configuration, instead of supplying current,…

Data Sheet help: Current flowing through a MOSFET module
In a MOSFET module, when looking at the data sheet can I assume the current through each MOSFET device is the given Id, or is Id the current moving through the entire MOSFET module?
For the data sheet attached I'm assuming the current through each…

How to run TTP223 Module on AC supply?
My question is about TTP223 module. It is operated on 3-5 Volt DC. But how can I run it on AC supply? I mean I don't want to use DC source. I want to run MOSFET instead of Relay by this.
