1N5818 vs 1N4007?

1. Forward voltage drop:

The typical forward voltage drop of the 1N5818 is around 0.5V, while the typical forward voltage drop of the 1N4007 is around 0.7V.

2. Maximum voltage and current ratings:

The 1N4007 can handle a maximum reverse voltage of 1000V, while the 1N5818 has a maximum reverse voltage rating of 30V. However, the 1N5818 has a higher maximum forward current rating than the 1N4007.

3. Switching speed:

The 1N5818 is a Schottky diode, which means it has a faster switching speed than the 1N4007. This makes it more suitable for use in high-frequency applications.
