Key Parameters

Substitute Part Grouping Explanation

Substitute equivalence in the Zener diode category is determined strictly by matching or exceeding key electrical and mechanical parameters. The provided substitute parts (1SMB5941BT3G, SZ1SMB5941BT3G) conform to the critical attributes: Zener voltage, maximum impedance, reverse leakage current, mounting type, package, and operating temperature. Additional features such as tolerance, power rating, RoHS, REACH compliance, MSL, and product status are also considered. Only parts with parameters matching those listed are included as substitutes.

Key parameters for substitution:

• 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
• Product Status
• Compliance (RoHS, REACH)
• Moisture Sensitivity Level (MSL)

Parameter Comparison

Engineering Selection Recommendations

All listed substitute Zener diodes maintain Active product status, equivalent operating temperature range, and mechanical package (DO-214AA, SMB) compatibility. Substitute parts (1SMB5941BT3G, SZ1SMB5941BT3G) provide enhanced tolerance and power ratings, and are ROHS3 compliant. The main part, SMBJ5941A/TR13, is RoHS non-compliant. Compliance and qualification status (AEC-Q101 for SZ1SMB5941BT3G) must be referenced from provided data for specific selection based on environmental and regulatory requirements. All alternatives possess REACH Unaffected and Moisture Sensitivity Level 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q1: What key parameters govern equivalency for Zener diode substitution?
A1: Equivalent Zener diodes are determined by matching the nominal Zener voltage, maximum impedance, reverse leakage current, package type, mounting configuration, operating temperature range, product status, and compliance metrics (RoHS, REACH).

Q2: Can 1SMB5941BT3G and SZ1SMB5941BT3G be directly substituted for SMBJ5941A/TR13?
A2: Based on the provided parameters—electrical (47 V Zener, 67 Ohms impedance, 1 µA leakage), mechanical (DO-214AA, SMB, surface mount), and compliance (Active status, REACH, RoHS)—both alternatives are suitable substitute models.

Q3: Are there any differences in tolerance and power ratings among substitutes?
A3: Yes. SMBJ5941A/TR13 features a tolerance of ±10% and power rating of 2 W, while substitute parts have ±5% tolerance and 3 W maximum power.

Q4: What are the compliance considerations when substituting?
A4: SMBJ5941A/TR13 is RoHS non-compliant. Substitute parts (1SMB5941BT3G, SZ1SMB5941BT3G) are ROHS3 Compliant, satisfying stricter environmental standards. All options remain REACH Unaffected.

Q5: Is the package identical between the main and substitute parts?
A5: Yes. All parts utilize the DO-214AA, SMB surface mount package.

Q6: What is the relevance of Moisture Sensitivity Level (MSL) in selection?
A6: All listed parts have Moisture Sensitivity Level 1 (Unlimited), suitable for standard surface mount processing environments.
