Substitute Part Grouping Explanation

Substitution of the SD103ASDM-7 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

  • Diode configuration (2 pair series connection)
  • Schottky technology type
  • Maximum DC reverse voltage (40 V)
  • Average rectified current per diode (350 mA)
  • Forward voltage characteristics (600 mV @ 200 mA)
  • Reverse recovery time (10 ns)
  • Reverse leakage current (5 µA @ 30 V)

Mechanical & Environmental Parameters:

  • Surface mount mounting type
  • SOT-23-6 package / case
  • SOT-26 supplier device package
  • Operating temperature range (-65°C ~ 125°C)

The SD103ASDM-7-F is identified as a direct substitute based on identical electrical specifications, mechanical packaging, and environmental ratings. The primary distinction is product status and compliance certification.
