Key Parameters

Substitute Part Grouping Explanation

Substitute Zener diodes are grouped based on matching the following parameters: voltage - Zener (nominal, 11 V), mounting type (surface mount), package (DO-214AA, SMB), and operating temperature (-65°C ~ 150°C). Additional selection criteria include power rating, tolerance, impedance, reverse leakage, RoHS compliance, MSL, and REACH status. Only products within the Diodes, Zener category are included.

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
• Supplier Device Package
• RoHS Status
• Moisture Sensitivity Level (MSL)
• REACH Status

Engineering Selection Recommendations

When selecting an equivalent Zener diode for SMBJ4741/TR13, verification of product status (active), RoHS compliance, and relevant certifications such as REACH status should be prioritized as shown in the provided parameters. Substitute parts 1SMB5926BT3G and SZ1SMB5926BT3G match the electrical and mechanical criteria based on the supplied data, and both are ROHS3 compliant with REACH unaffected status, while SMBJ4741/TR13 is RoHS non-compliant.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for selecting a Zener diode substitute?
A1: Substitutes must match key parameters such as nominal Zener voltage, tolerance, power rating, maximum impedance, reverse leakage, package/case type, mounting method, operating temperature, and compliance certifications.

Q2: Are the substitute parts directly interchangeable in terms of form factor?
A2: Both the main part and substitutes utilize the DO-214AA, SMB surface-mount package, making them mechanically interchangeable based on the provided information.

Q3: How does RoHS compliance affect selection?
A3: If RoHS compliance is a requirement, choose a substitute with a matching RoHS status. 1SMB5926BT3G and SZ1SMB5926BT3G are ROHS3 compliant, while SMBJ4741/TR13 is RoHS non-compliant.

Q4: Are there differences in electrical performance between the main and substitute parts?
A4: Differences are found in power rating, tolerance, and impedance. Substitute parts offer higher power (3 W), tighter tolerance (±5%), and lower maximum impedance compared to SMBJ4741/TR13.

Q5: Are substitutes suitable for the same operating temperature range?
A5: All compared parts specify an operating temperature range of -65°C to 150°C.

Q6: What should be checked for automotive applications?
A6: The SZ1SMB5926BT3G includes automotive qualification (AEC-Q101) as indicated in the parameter list.
