MAZ8075GML Equivalent & Substitute Parts

Part Overview

The MAZ8075GML is a Zener diode manufactured by Panasonic Electronic Components, rated at 7.5 V nominal voltage with 150 mW maximum power dissipation. This component is packaged in SMini2-F3 (SC-90, SOD-323F) surface mount configuration. The product is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain the 7.5 V Zener voltage specification while accommodating variations in power rating, impedance, and package form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAZ8075GML is determined by the following critical parameters:

Primary Matching Criteria:

• Voltage - Zener (Nom): 7.5 V (exact match required)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Factors:

• Power - Max: Substitute parts must equal or exceed 150 mW
• Impedance (Max): Lower impedance values indicate improved performance characteristics
• Tolerance: Tighter tolerance (±2%) provides superior voltage regulation
• Reverse Leakage Current: Lower values indicate better device quality
• Package / Case: SOD-323F compatible packages or functionally equivalent surface mount packages

The three identified substitute parts (BZX585-B7V5,115; BZX585-B7V5,135; BZX84J-B7V5,115) all maintain the 7.5 V Zener voltage specification and surface mount configuration. All substitutes are manufactured by Nexperia USA Inc. and carry active product status with automotive-grade qualifications.

Engineering Selection Recommendations

BZX84J-B7V5,115 (Recommended Primary Substitute)

The BZX84J-B7V5,115 is the optimal substitute for direct replacement of the MAZ8075GML. This part maintains identical package configuration (SC-90, SOD-323F), ensuring PCB layout compatibility without redesign. The BZX84J-B7V5,115 provides 550 mW power rating, exceeding the original 150 mW specification. The device carries AEC-Q101 automotive qualification and ROHS3 compliance. Impedance is reduced to 10 Ohms, and tolerance is improved to ±2%. Product status is active with 3247 units in stock.

BZX585-B7V5,115 and BZX585-B7V5,135 (Alternative Substitutes)

Both BZX585 variants provide 300 mW power rating and ±2% tolerance with 10 Ohm impedance. These parts require package transition from SOD-323F to SOD-523, necessitating PCB layout modification. Both carry AEC-Q100 automotive qualification and ROHS3 compliance. BZX585-B7V5,115 has 3165 units in stock; BZX585-B7V5,135 has 927 units in stock. Selection between these variants depends on specific procurement and supply chain requirements.

Compliance and Certification Status

All substitute parts are active products with automotive-grade qualifications (AEC-Q100 or AEC-Q101) and ROHS3 compliance. All maintain MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original component specification.

Frequently Asked Questions (FAQ)

Q: Can BZX84J-B7V5,115 be used as a direct replacement for MAZ8075GML without PCB modification?

A: Yes. The BZX84J-B7V5,115 uses identical package configuration (SC-90, SOD-323F), allowing direct PCB footprint compatibility. No layout changes are required.

Q: What is the primary difference between BZX585 and BZX84J substitute options?

A: The BZX585 series uses SOD-523 package, requiring PCB redesign. The BZX84J-B7V5,115 uses SOD-323F package, matching the original MAZ8075GML footprint. Power ratings differ: BZX585 provides 300 mW; BZX84J-B7V5,115 provides 550 mW.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All three substitute parts carry automotive-grade qualifications (AEC-Q100 or AEC-Q101) and are ROHS3 compliant, meeting automotive industry standards.

Q: How does the ±2% tolerance of substitute parts compare to the MAZ8075GML's ±6% tolerance?

A: The ±2% tolerance of all substitute parts provides tighter voltage regulation compared to the original ±6% specification. This represents improved performance characteristics for voltage reference applications.

Q: What is the significance of the reduced impedance (10 Ohms) in substitute parts versus the original 20 Ohms?

A: Lower impedance indicates superior voltage regulation performance and reduced dynamic resistance. This provides better transient response and improved voltage stability under load variations.

Q: Can BZX585-B7V5,115 and BZX585-B7V5,135 be used interchangeably?

A: Yes. Both parts are electrically identical with matching specifications (7.5 V, 300 mW, ±2% tolerance, 10 Ohm impedance). Selection depends on inventory availability and procurement requirements.

Q: What is the reverse leakage current difference between the original and substitute parts?

A: The MAZ8075GML specifies 100 nA reverse leakage at 5 V. All substitute parts specify 1 µA reverse leakage at 5 V. This represents a 10-fold increase in leakage current, which is acceptable for most applications but should be verified for precision voltage reference circuits.

Q: Are moisture sensitivity levels identical across all parts?

A: Yes. The MAZ8075GML and all three substitute parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
