Application Scenarios & Design Considerations

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

Alternative Part Number

  • BZX55C2V4 --: 2.4V zener in a DO-35 axial package with similar tolerance and power rating, a common cross for the ZMM5221B.
  • 1N5221B --: JEDEC 1N5221B is the axial-lead equivalent of the 2.4V zener, widely available and electrically compatible.
  • MMSZ5221B --: SOD-123 surface-mount 2.4V zener with the same 5221B voltage designation, suitable when a smaller SMD package is acceptable.
  • BZT52C2V4 --: 2.4V zener in SOD-123 with similar power rating and tolerance, widely available and pin-compatible substitute.
