MAZ8068GML Equivalent & Substitute Parts

Part Overview

The MAZ8068GML is a Zener diode manufactured by Panasonic Electronic Components, rated at 6.8 V nominal with 150 mW maximum power dissipation in a SMini2-F3 surface mount package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and production continuity. Substitute parts must maintain the 6.8 V zener voltage specification while accommodating variations in power rating, tolerance, and package form factors compatible with surface mount assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAZ8068GML is determined by the following critical parameters:

Primary Matching Criteria:

• Zener voltage: 6.8 V nominal (fixed requirement)
• Mounting type: Surface mount (fixed requirement)
• Package compatibility: SOD-323F or SC-90 form factors

Secondary Compatibility Parameters:

• Power dissipation rating: Substitute parts rated at 375 mW or 550 mW exceed the original 150 mW specification, providing enhanced thermal capability
• Voltage tolerance: Substitute parts offer ±2% to ±5% tolerance, improving upon the original ±6% specification
• Impedance: Substitute parts range from 8 to 15 Ohms, compared to the original 20 Ohms maximum
• Reverse leakage current: Substitute parts specify 2 µA @ 4 V, compared to the original 100 nA @ 4 V

All identified substitute parts maintain the 6.8 V zener voltage and surface mount configuration. The substitute parts listed are active products with current manufacturing status and automotive-grade qualifications where applicable.

Engineering Selection Recommendations

BZT52H-C6V8,115 (NXP Semiconductors)

This substitute provides 375 mW power dissipation with ±5% tolerance and AEC-Q101 automotive qualification. The SOD-123F package differs from the original SMini2-F3 form factor and requires PCB layout verification for footprint compatibility. This option is suitable for applications where the increased power rating and improved tolerance are beneficial and package transition is feasible.

BZX84J-B6V8,115 (Nexperia USA Inc.)

This substitute maintains the SC-90/SOD-323F package compatibility with the original MAZ8068GML, providing 550 mW power dissipation and ±2% tolerance. AEC-Q101 automotive qualification and ROHS3 compliance are included. The improved impedance specification (15 Ohms) and tighter tolerance make this option suitable for direct replacement in applications requiring package form factor consistency.

BZX84J-C6V8,115 (Nexperia USA Inc.)

This substitute also maintains SC-90/SOD-323F package compatibility, offering 550 mW power dissipation with ±5% tolerance and AEC-Q101 automotive qualification. ROHS3 compliance and REACH unaffected status are provided. This option is suitable for applications where package compatibility is required and ±5% tolerance is acceptable.

All substitute parts are active products with current manufacturing status and automotive-grade certifications, supporting long-term design continuity and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can BZT52H-C6V8,115 be used as a direct replacement for MAZ8068GML?

A: BZT52H-C6V8,115 maintains the 6.8 V zener voltage and surface mount configuration. However, the package form factor differs (SOD-123F versus SMini2-F3/SC-90). PCB layout and footprint compatibility must be verified before implementation. The increased power rating (375 mW versus 150 mW) and improved tolerance (±5% versus ±6%) are compatible with the original specification.

Q: What is the primary difference between BZX84J-B6V8,115 and BZX84J-C6V8,115?

A: Both parts maintain identical package compatibility (SC-90/SOD-323F) with the original MAZ8068GML and provide 550 mW power dissipation. The primary difference is voltage tolerance: BZX84J-B6V8,115 specifies ±2% tolerance, while BZX84J-C6V8,115 specifies ±5% tolerance. Selection depends on circuit requirements for voltage regulation precision.

Q: Are all substitute parts automotive-qualified?

A: Yes. BZT52H-C6V8,115, BZX84J-B6V8,115, and BZX84J-C6V8,115 all carry AEC-Q101 automotive qualification and are classified as automotive-grade components, supporting applications requiring automotive reliability standards.

Q: Does package form factor affect electrical performance?

A: Package form factor does not alter the electrical characteristics of the zener diode (voltage, tolerance, power rating). However, package selection affects PCB layout, thermal management, and assembly compatibility. BZX84J-B6V8,115 and BZX84J-C6V8,115 maintain the original SC-90/SOD-323F package, eliminating layout redesign requirements.

Q: What is the significance of the improved impedance specifications in substitute parts?

A: Lower impedance values (8 to 15 Ohms in substitutes versus 20 Ohms in the original) indicate improved dynamic response characteristics and reduced voltage variation under load transients. This enhancement is compatible with the original specification and provides performance margin.

Q: Are moisture sensitivity levels equivalent across all parts?

A: Yes. The original MAZ8068GML and all substitute parts specify Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions and compatibility with standard surface mount assembly and storage conditions.
