Ordered these Mosfets to repair a damaged power supply. They arrived on time and performed well.

Thought it was fake because of the Price (Official IRLZ44s cost 36$ for the same quantity) so it looked Suspicious but it seems to be real, it seems to be working as intended, I Have not yet checked if its PBF, I Would most Certainly recommend.

Iâm using these to step up an output from an ESP 32 to 5 volts to power SSRâs that are switching 24 V DC or 110 V AC for the customers project. I have 18 of them running and the customer is very pleased with them and theyâre working perfectly.

I used this optocoupler to repair a... pinball machine! This part replaced a 4N25 optocoupler on the pinball machine's motor controller circuit board. Once installed, the machine powered-up and worked perfectly. I like that the parts were well packaged and arrived quickly and I like that the parts came in a 6-pack (in case I need one in the future, as I have three other machines that use 4N25's). Delighted customer!

I was using a Raspberry Pi (Model 4, 4GB) to control power from a high power source - I tested with 12V, 16V, and 20V sources. It worked great with the 3.3V from the GPIO pins.To get this working, I had the positive voltage from the power source connected to my load (the positive side of the load), then the negative/ground voltage from the power source connected to the Source pin (right pin when looking at it from the "front"), the Drain pin (middle pin) connected to the negative side of my load, and the Gate pin (right pin) connected to the GPIO pin of the Raspberry Pi. You can find guides for the Raspberry Pi & RGB LED-Strips setups that people have posted with circuits using this and the IRLZ34.

I'm using these for high side switching and current control. Vgs was about -2V, well within spec. Nice low Rds-on, keeps Vds low, and therefore low power dissipation. For low current applications, a heatsink is not needed.

The Allecin TIP41 100V 6A NPN Darlington power transistor worked well for me. My wife has a LED-lighted magnifying glass/lamp that died; the wall wart power supply died. A replacement power supply also did not work, so I purchased some parts-including these TIP41s-to build a 50 mA current source to drive the LEDs. I grabbed a TIP 41, built a little current source into the lamp housing, and fired it up. The LEDs came up just like they were supposed to at roughly the correct brightness. So, the TIP41 worked just as it was supposed to. However, note that the TIP41 transistors came loose in a little plastic box with no ESD protection. Given this, the transistors could all be damaged from ESD, and, if they work immediately, they could fail later from a latent defect. For that I remove a star. These days TIP41s seem to be a cheap âpopcornâ part sourced from many different vendors at a cheap price. The cases all have a âWSâ marking with a logo that I had never seen before, so I assume these are all parts sourced from China, and they might not meet requirements specified by TI or Motorola (ON Semi), and could be of very low quality, with very poor reliability (especially given no ESD protection). However, the parts were/are cheap, and my application is a non-critical application; if the TIP41 dies, I will just replace it in the circuit. Note also that given that the application is non-critical, I did not bother to test the parts, and I took no measurements and performed no testing on the current source that I built other than to confirm the brightness of the LEDs was about right. I buttoned up the light, and the wife is happy; end of story. Please allow me to emphasize again that I did not test the parts or the circuit, other than confirm that the LED brightness was about right, and thus have no clue regarding the quality or reliability of the parts. The one TIP41 that I used seemed to work correctly. I would not recommend their use in a critical application.
