Alternative Part Number

  • 1N4745A --: Same 16V 1W zener diode in the classic 1N47xx axial series; widely available and electrically equivalent.
  • BZX85C16 --: 16V 1.3W zener in DO-41 package; higher power margin and same manufacturer, good drop-in for most SML4745 applications.
  • 1N4745A-TR --: Vishay's 1N47xx-series 16V 1W zener, same DO-41 form factor and ratings as the SML4745.
