Alternative Part Number

  • 1N4747A --: 20V 1W zener diode in DO-41 package, a common general-purpose replacement for the 20V zener function of the SM2JZ47.
  • BZX55C20 --: 20V 500mW zener diode with similar voltage rating and small-signal package, suitable for lower-power substitution.
  • 1N5357B --: 20V 5W zener diode offering higher power margin, usable where the original 20V zener needs robust power handling.
