Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based strictly on matching or exceeding the key parameters required for a Zener diode application. Substitutes must maintain the same Voltage - Zener (24 V), an equal or higher Power - Max rating, equivalent or tighter Tolerance, the same or lower Impedance (Max) (19 Ohms), equivalent or lower Reverse Leakage Current and Forward Voltage, and matching Operating Temperature range. Mechanical compatibility is ensured by identical Mounting Type and Package / Case (DO-214AA, SMB). Compliance parameters such as RoHS, REACH, and MSL are included for regulatory alignment.

Key parameters for substitution:

• Voltage - Zener (Nom) (Vz)
• Tolerance
• Power - Max
• Impedance (Max) (Zzt)
• Current - Reverse Leakage @ Vr
• Voltage - Forward (Vf) (Max) @ If
• Operating Temperature
• Mounting Type
• Package / Case
• RoHS Status
• MSL
• REACH Status
• ECCN
• Product Status

Parameter Comparison

Engineering Selection Recommendations
