SS1P3L vs MBR0520

The SS1P3L and MBR0520 are both Schottky diodes but differ in their specifications and characteristics.

  • Voltage Rating: The SS1P3L has a voltage rating of 30V, while the MBR0520 has a voltage rating of 20V. This means that the SS1P3L can handle higher voltages than the MBR0520.
  • Forward Voltage Drop: The forward voltage drop of the SS1P3L is typically lower than that of the MBR0520. This indicates that the SS1P3L may have slightly better conduction efficiency.
  • Current Rating: The MBR0520 generally has a higher current rating compared to the SS1P3L. This means that the MBR0520 can handle larger currents without compromising its performance.
  • Package Type: The SS1P3L is available in a SOD-323 package, which is smaller than the SOD-123 package used for the MBR0520. Therefore, the SS1P3L requires less board space for integration.
