Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAZ83900ML is based on electrical and mechanical parameter alignment within the Zener diode category. The primary substitution criteria are:

Critical Matching Parameters:

• Voltage - Zener (Nom): 39 V (exact match required)
• Package / Case: SC-90, SOD-323F (mechanical compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Moisture Sensitivity Level: 1 (Unlimited) (storage and handling compatibility)

Allowable Parameter Variations:

• Power - Max: Substitute must equal or exceed 150 mW
• Tolerance: Substitute may have tighter tolerance than ±5%
• Impedance (Max): Substitute must not exceed 300 Ohms
• Current - Reverse Leakage @ Vr: Substitute specifications are acceptable within design margin
• Voltage - Forward (Max) @ If: Substitute specifications are acceptable within design margin

The UDZVFHTE-1739B from Rohm Semiconductor meets all critical matching parameters and allowable variations, qualifying it as a direct substitute for the MAZ83900ML.

Engineering Selection Recommendations

The UDZVFHTE-1739B is qualified as a direct substitute for the MAZ83900ML based on the following engineering criteria:

Electrical Compatibility: Both devices operate at 39 V nominal Zener voltage with identical maximum impedance specifications. The Rohm substitute provides 200 mW power rating, exceeding the 150 mW requirement of the original part, offering improved thermal margin in the application.

Mechanical Compatibility: Both components utilize identical SC-90 and SOD-323F package configurations, ensuring pin-for-pin compatibility and identical PCB footprints for surface mount assembly.

Product Status and Compliance: The MAZ83900ML is obsolete, whereas the UDZVFHTE-1739B maintains active product status with current manufacturing support. The Rohm device carries AEC-Q101 automotive qualification and ROHS3 compliance, providing enhanced supply chain reliability and regulatory alignment for applications requiring automotive-grade components.

Moisture Sensitivity: Both parts share MSL 1 (Unlimited) classification, eliminating moisture-related handling or storage requirement changes during substitution.

Frequently Asked Questions (FAQ)

Q: Can the UDZVFHTE-1739B be used as a direct replacement for the MAZ83900ML in existing designs?

A: Yes. Both devices share identical 39 V Zener voltage, SC-90/SOD-323F package configuration, and MSL 1 moisture sensitivity rating. The Rohm substitute provides higher power dissipation (200 mW vs. 150 mW) and tighter voltage tolerance (±2.51% vs. ±5%), making it functionally compatible for direct substitution without PCB or assembly modifications.

Q: What are the key differences between these two Zener diodes?

A: The primary differences are manufacturer, product status, and performance specifications. The MAZ83900ML is obsolete; the UDZVFHTE-1739B is active. The Rohm device offers 50 mW additional power capacity, tighter voltage tolerance, and automotive-grade qualification (AEC-Q101). Reverse leakage current is slightly higher in the Rohm part (100 nA vs. 50 nA @ 30 V), remaining within acceptable design margins.

Q: Are there any package or footprint considerations when substituting these parts?

A: No. Both the MAZ83900ML and UDZVFHTE-1739B use identical SC-90 and SOD-323F package designations. PCB footprints, lead spacing, and mounting procedures remain unchanged. No design layout modifications are required.

Q: Does the UDZVFHTE-1739B meet automotive or compliance requirements?

A: The UDZVFHTE-1739B carries AEC-Q101 automotive qualification and ROHS3 compliance certification. The original MAZ83900ML does not specify these qualifications. If automotive-grade components are required, the Rohm substitute provides enhanced qualification status.

Q: What is the moisture sensitivity level for both parts?

A: Both the MAZ83900ML and UDZVFHTE-1739B are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage, handling, and reflow procedures remain identical between the two devices.

Q: Can the higher power rating of the UDZVFHTE-1739B cause issues in the application?

A: No. The 200 mW rating of the Rohm device exceeds the 150 mW requirement of the original part. Higher power capacity provides additional thermal margin and does not introduce compatibility issues. The device will operate within the same voltage and current parameters as the original design.
