Application Scenarios & Design Considerations

Surface Mount Zener Voltage Regulators

Alternative Part Number

  • BZX55C15 --: Same 15V zener voltage in a DO-35 axial package with similar 500mW power rating, widely available and a direct functional replacement.
  • 1N4744A --: 15V 1W zener diode in DO-41 package; higher power margin makes it a robust substitute where board space allows.
  • MMSZ5245B --: 15V zener in SOD-123 surface-mount package, suitable alternative when a smaller SMD footprint is acceptable.
  • BZT52C15 --: 15V zener diode in SOD-123 package with similar power rating and tolerance, widely available and pin-compatible replacement.
