EEVblog 1746 - Schottky vs PN Diodes & Measurement Traps

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://ift.tt/mltJkG9 https://ift.tt/DbaWC0f https://ift.tt/XI1L5Hf Forum: https://ift.tt/FnrPIUA 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!
