Alternative Part Number

  • BZT52C27 --: 27V zener diode in SOD-123 package with similar power rating and voltage tolerance, widely available and a common drop-in replacement.
  • MMSZ5254B --: 27V zener in SOD-123 with 500mW rating, matches the ZMM27 voltage and package style for general regulation use.
  • 1N4750A --: 27V 1W zener diode in DO-41 axial package, suitable when higher power dissipation is acceptable and through-hole mounting fits the design.
  • 1N5254B --: 27V zener diode in DO-35 axial package, 500mW, electrically equivalent and usable where package style allows.
