Join Barron Stone for an in-depth discussion in this video Diode characteristics, part of Electronics Foundations: Semiconductor Devices.
- [Instructor] There are three primary characteristics…that I consider when choosing which diode…to use in my circuit.…Forward voltage, which is the voltage at which…the diode turns on and allows forward current…to flow through it,…the breakdown voltage,…which is the negative voltage…at which the diode fails to stop current…from flowing backwards through it,…and the maximum forward current,…which is the amount of forward current…the diode can handle before it will overheat and burn up.…To show you how to buy in and interpret…these diode characteristics,…I'll look at the data sheet for a common 1N4148…small signal diode.…
The 1N4148 diode is designed for general-purpose usage.…It has a moderate forward voltage drop,…but it's not designed to handle much forward current.…To find the data sheet for that diode,…I'll go to my search engine…and type in the part number 1N4148…and the word datasheet.…I see that there are several datasheets available…for the 1N4148 diode from different manufacturers.…For this video, I'll look at the datasheet from Vishay.…
