Key Parameters

Substitute Part Grouping Explanation

Substitute or equivalent Zener diodes are selected by strict matching to critical electrical and mechanical parameters. The allowed parameters for substitution include: Zener voltage (11 V), maximum power rating (2 W or above), impedance (5.5 Ohms), maximum reverse leakage current (1 µA @ 8.4 V), maximum forward voltage, tolerance (must not be tighter than specified), identical package/case (DO-214AA, SMB), mounting type (surface mount), and equal or wider operating temperature range. Environmental and compliance certifications such as RoHS and REACH status, as well as inventory availability, are also considered for application-specific requirements.

Key matching parameters:

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

Parameter Comparison

Engineering Selection Recommendations

The SMBJ5926C/TR13 is RoHS non-compliant, whereas the substitute 1SMB5926B-13 is ROHS3 Compliant. For applications requiring RoHS compliance, 1SMB5926B-13 is suitable from a regulatory and certification perspective. Both parts are active and available in original packaging, with comparable Moisture Sensitivity Level (1, Unlimited) and REACH status (Unaffected).

Frequently Asked Questions (FAQ)

Q1: What are the most critical parameters for substituting SMBJ5926C/TR13 Zener diodes?
A1: Key substitution parameters are Zener voltage (11 V), power (≥2 W), impedance (5.5 Ohms), tolerance, reverse leakage current, package compatibility (DO-214AA, SMB), surface mount type, and the required operating temperature range.
