Frequently Asked Questions (FAQ)
Q1: What primary parameters determine if a Zener diode is a suitable substitute?
A1: Equivalent Zener diode selection is based on matching the nominal Zener voltage, maximum power rating, tolerance, impedance, reverse leakage current, forward voltage at rated current, operating temperature, mounting type, and package/case.
Q2: Is the package type identical for these substitute parts?
A2: Both SMBJ5922A/TR13 and 3SMBJ5922B-TP use the DO-214AA, SMB surface mount package.
Q3: What certifications or compliance differences exist between the substitute parts?
A3: SMBJ5922A/TR13 is RoHS non-compliant, whereas 3SMBJ5922B-TP is ROHS3 compliant. Both are REACH unaffected and have an MSL of 1 (Unlimited).
Q4: Are the electrical parameters consistent between original and substitute parts?
A4: The nominal Zener voltage of 7.5 V, maximum impedance, and reverse leakage current are consistent. Tolerance and forward voltage differ between the two models, as well as the maximum power rating.
Q5: How does the operating temperature range compare?
A5: SMBJ5922A/TR13 has an operating temperature range of -65°C ~ 150°C, while 3SMBJ5922B-TP ranges from -55°C ~ 150°C.
Q6: Can the substitute part be used for the same mounting process?
A6: Both parts are designed for surface mount applications, utilizing the DO-214AA, SMB footprint.
