Key Parameters

Substitute Part Grouping Explanation

Substitute Zener diodes for SMBJ5925A/TR13 are determined through strict matching of critical parameters: Zener voltage (Vz), tolerance, power dissipation, maximum dynamic impedance, reverse leakage current, forward voltage, operating temperature range, mounting type, and package/case. Only parts that comply within or exceed these specifications and share a compatible mechanical footprint qualify as valid substitutes.

The following key parameters have been used to define substitution criteria:

• 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
