Note: Always install the diode with the correct polarity. The silver band indicates the cathode (−). The 1N4007 is suitable for low-frequency rectification and general-purpose protection circuits, but it is not recommended for high-speed switching applications. For high-frequency circuits, consider using a fast recovery or Schottky diode instead.
