Key Parameters

Substitute Part Grouping Explanation

Substitution is determined based on the following strictly observed electrical and mechanical parameters: Zener voltage (Vz), maximum power dissipation, tolerance, impedance (Zzt), reverse leakage current at specified voltage, forward voltage at specified current, operating temperature range, mounting type, package/case, and product category. All listed substitute Zener diodes meet the defined criteria for these parameters and use an identical or equivalent mechanical package, ensuring functional and assembly compatibility within specified limits.

Parameter Comparison

Engineering Selection Recommendations

Selection may be determined by product status, RoHS compliance, MSL, and REACH status. SMBJ5936A/TR13 is active but not RoHS compliant. Substitute part 1SMB5936BT3G is active, holds ROHS3 compliance, MSL 1 (Unlimited), and REACH Unaffected status. These distinctions must be considered based on the end application's compliance and certification requirements.

Frequently Asked Questions (FAQ)

Q: What determines the eligibility of 1SMB5936BT3G as an equivalent for SMBJ5936A/TR13?
A: Substitution is based strictly on equivalent Zener voltage, power rating, maximum impedance, reverse leakage, forward voltage, operating temperature range, mounting type, and identical DO-214AA, SMB package.

Q: Are the packages for SMBJ5936A/TR13 and 1SMB5936BT3G mechanically compatible?
A: Both use the DO-214AA, SMB package, ensuring physical compatibility for surface-mount assembly.

Q: Does RoHS compliance differ between these parts?
A: SMBJ5936A/TR13 is RoHS non-compliant. 1SMB5936BT3G is ROHS3 compliant.

Q: Are there differences in voltage, power, or temperature ratings?
