M7 general purpose diode in DO-214AC (SMA) package (surface mount version of 1N4007)[1]
SS14 schottky barrier diode in DO-214AC (SMA) package (surface mount version of 1N5819)[2]

DO-214 is a standard that specifies a group of semiconductor packages for surface mounted diodes.


The standard includes multiple package variants:[3][4]

  • DO-214AA, also known as SMB,[5] is the middle size.
  • DO-214AB, also known as SMC,[6] is the largest size.
  • DO-214AC, also known as SMA,[7] is the smallest size.
  • DO-214BA, also known as GF1
