Application Scenarios & Design Considerations

ZENER DIODES Voltage: 2.4-56V P e a k Pulse Power: 500mW Glass passivated junction

Alternative Part Number

  • 1N4744A --: 15V 1W axial-lead Zener diode with equivalent voltage and power rating, widely available and a common through-hole substitute.
  • BZX55C15 --: 15V 500mW axial Zener diode in the same DO-35 package family, suitable for lower-power replacement.
  • MMSZ5244B --: 15V 500mW surface-mount Zener with the same 5244B voltage code, useful when an SMD equivalent is acceptable.
  • 1N5244B --: Same 14V zener diode in the standard 1N5244B DO-35 axial package; widely available and electrically equivalent to the ZMM5244B.
  • BZX55C14 --: 14V 0.5W zener in DO-35 with similar tolerance and power rating, a common European cross for the ZMM5244B.
