I'm trying to design a circuit for a relay similar to the following (except using SMT components):
When I went to Mouser to try to find a suitable SMT diode to use in place of the 1N4001, I noticed there are four main categories:
TVS Diodes (21,395) Rectifiers (9,872) Schottky Diodes & Rectifiers (8,259) Zener Diodes (15,726)
I'm pretty sure Zener & Schottky diodes are not supposed to be used as flyback diodes, which leaves
TVS Diodes and
Looking on Wikipedia, a TVS diode is shown as:
I did a little searching online and it seems some designs use a
Rectifier like the 1N4001, while others use TVS diodes. I couldn't find a clear answer as to which is better.
Is there any advantage to using a
TVS diode over a
Rectifier diode for flyback applications such as a relay circuit?
