ss22a is a common schottky barrier diode, which is a surface mount device and adopts SMA package. It is widely used in modern electronic circuits due to its low forward voltage drop and fast switching characteristics.

Technical Parameters

  • Maximum reverse voltage (VRRM): 20V
  • Average forward rectified current (IF): 2A
  • Forward voltage drop (VF): Typical 0.45V (at IF=1A)
  • Maximum reverse leakage current (IR): 0.2mA (at TA=25°C)
  • Operating temperature range: -55°C to+125°C

These parameters indicate that SS22A is suitable for low-voltage, medium-current applications, and its low forward voltage drop helps reduce power loss.

Package

SS22A is generally available in DO-214AC (SMA) surface mount package,which is compact and easy to mount automatically. Therefore, it is suitable for modern high-density circuit board design.

Features and Advantages

  • Low forward voltage drop: reduces power loss and improves energy efficiency
  • Fast switching speed: suitable for high-frequency circuits
  • No reverse recovery time: avoids energy loss during switching
  • Compact package: suitable for miniaturization of portable devices.
