Substitute Part Grouping Explanation

Substitute parts for the MM3Z22VT1GX are identified based on strict electrical and mechanical parameter matching. The substitution criteria include:

  • Zener Voltage: Nominal value of 22 V with ±5% tolerance
  • Power Dissipation: Maximum 300 mW rating
  • Impedance: Maximum 25 Ohms
  • Reverse Leakage Current: 50 nA @ 17 V
  • Forward Voltage: 1.1 V maximum @ 100 mA
  • Operating Temperature: 150°C junction temperature
  • Package Configuration: SOD-323 surface mount package
  • Compliance: RoHS3 compliant, REACH unaffected status

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The SZMM3Z22VT1GX meets all specified electrical and mechanical requirements and is therefore qualified as a substitute part.
