https://stream.echo6.co/videos/watch/e0096fd6-a96d-4678-8474-068dbc3df9ea Demonstrating the difference between Schottky diodes and PN junction silicon diodes, and how your multimeter can influence your measurement when troubleshooting. Answering an interesting Twitter question. https://x.com/blind_via/status/2052223991839170919 https://www.tti.com/content/ttiinc/en/resources/blog/infographics/schottky-diodes.html https://engineering.purdue.edu/~ee606/downloads/ECE606_f12_Lecture17.pdf Forum: https://www.eevblog.com/forum/blog/eevblog-1746-schottky-vs-pn-diodes-measurement-traps/ 00:00 - Twitter question 01:21 - Recreating the problem 03:08 - Why doesn't it read zero volts? Let's try a PN junction diode 04:21 - Schottky vs PN Junction diodes, they are NOT the same! 06:06 - What about a diode tester? 07:15 - Why doesn't the Schottky diode work like a diode? 08:39 - It's a multimeter measurement TRAP! 10:37 - A closer look at Schottky diodes 14:21 - Datasheet inspection, and advantages vs disadvantages of Schottky diodes 15:21 - Reverse leakage current, PN vs Schottky 17:16 - THREE orders of magnitude difference! 22:29 - Digital vs Analog multimeter, Analog WINS!
