Alternative Part Number

  • BZT52C15 --: 15V zener in SOD-123, same 500mW class as ZMM5245B; widely available and pin-compatible.
  • MMSZ5245B --: Direct 15V zener equivalent in SOD-123 with matching 500mW rating and tolerance.
  • 1N4744A --: 15V 1W zener in DO-41; higher power margin, suitable if board space allows axial package.
  • 1N4745A --: DO-41 axial 16V zener with similar tolerance and power rating, widely available and easy to substitute in through-hole designs.
  • BZX55C16 --: 16V 500mW zener in DO-35 package, close electrical match to the ZMM5245B with broad availability.
