Frequently Asked Questions (FAQ)

Q: Which electrical parameters must match for Zener diode substitution in this category?
A: Voltage - Zener (Nom) (Vz), Tolerance, Power - Max, Impedance (Max) (Zzt), Current - Reverse Leakage @ Vr, and Voltage - Forward (Vf) (Max) @ If must strictly match or challenge design tolerance thresholds.

Q: Why is package type important for these substitutions?
A: All parts share the DO-214AA, SMB package and Surface Mount configuration, ensuring mechanical compatibility for automated PCB assembly.

Q: Are there differences in compliance among the substitutes?
A: SMBJ5368A/TR13 is RoHS non-compliant, while both substitutes are ROHS3 compliant. All listed diodes are REACH unaffected.

Q: Is operating temperature range a factor in these substitutions?
A: All listed parts support an operating temperature range of -65°C ~ 150°C, fulfilling equivalent environmental requirements.

Q: How do differences in rated power affect substitution?
A: Substitute parts are rated at 3 W versus the original’s 5 W; applications must align with available input for power handling, as listed.

Q: What documentation or certification should be checked for final selection?
A: Product status, RoHS compliance, REACH status, and any indicated qualification or automotive grade should match application and regulatory requirements.
