Application Scenarios & Design Considerations

1/2 Watt ZENER DIODES (2.28V to 50V) WIDE VOLTAGE RANGE

Alternative Part Number

  • BZT52C3V9 --: 3.9V zener diode in SOD-123 package with similar power rating and voltage tolerance, widely available and pin-compatible replacement.
  • MMSZ5230B --: 3.9V zener diode in SOD-123 with 500mW rating, matches the voltage and package of the original for direct drop-in use.
  • 1N4730A --: 3.9V 1W zener diode in DO-41 axial package, suitable alternative when through-hole mounting is acceptable and higher power dissipation is beneficial.
