Atorch DL24 Electronic Load Burning MOSFET Fix
Thank you for provided work at this fix. Can you give any mark of this diode or any links for right parameters of him? As I understand its need to be 12V 1W diode. I found diodes with marking "1N4742" and as I think from video it can be used for this purpose, right?
I can provide link for diode I found on Aliexpress if you need
Thanks for commenting. I would suggest using 1N4743+, not 1n4742, as we need to clamp voltage spikes more than 12V. If you use 1N4742, the diode can become very hot at high currents, as the power adapter we are using itself is 12V and the V_gs can reach 12V. Extremely sorry for late reply. I am not active on TH-cam.
@@electrotsmishar Thanks for the feedback, and as far as I understood from the answer "1N4743+" - 1N4743 will do, and by "+" you mean other following variations of this diode - 1N4744-15V, 1N4745-16V, 1N4746-18V... Did I understand you correctly? Or did you mean the marking "1N4743+"? Although Google does not give any results for this option at all. I am not an electronics specialist and I apologize for possible "childish questions". Thank you!
You're absolutely correct, by 4743+ I meant higher rating than 12V. But, don't exceed 15V
Don't worry. Nothing childish about your question
