Engineering Selection Recommendations

Product status for all listed part numbers is Active. RoHS and REACH compliance varies: SMBJ5357A/TR13 is RoHS non-compliant, while 1SMB5932BT3G and SZ1SMB5932BT3G are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level is 1 (Unlimited) for all parts. Selection may be aligned to compliance requirements and certifications as explicitly stated.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for a Zener diode substitute in surface mount SMB packages?
A1: Substitute selection must be based on Voltage - Zener (Nom), Tolerance, Power - Max, Impedance (Max), Current - Reverse Leakage at the specified test voltage, Voltage - Forward (Max) at specified current, Operating Temperature, Mounting Type, Package / Case, Supplier Device Package, and compliance status.

Q2: Does package compatibility guarantee direct electrical substitution between SMBJ5357A/TR13 and the substitute parts?
A2: The package compatibility (DO-214AA, SMB) allows for direct surface mount replacement; electrical substitution depends on all key electrical parameters provided.

Q3: Are there differences in tolerance and power rating between SMBJ5357A/TR13 and its substitutes?
A3: SMBJ5357A/TR13 offers ±10% tolerance and 5 W power rating; its substitutes specify ±5% tolerance and 3 W power rating.

Q4: What compliance differences exist among the main part and substitutes?
A4: SMBJ5357A/TR13 is RoHS non-compliant, while 1SMB5932BT3G and SZ1SMB5932BT3G are ROHS3 compliant. All are listed as REACH unaffected.

Q5: Is the operating temperature range consistent across all compared parts?
A5: All parts declare an operating temperature range of -65°C ~ 150°C.

Q6: What should be considered regarding electrical characteristics when selecting a substitute?
A6: All selection must strictly follow explicitly listed electrical characteristics: Zener voltage, tolerance, power, impedance, reverse leakage, forward voltage, and temperature range as given above.
