Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAZ30750ML is determined by the following critical parameters:

Primary Matching Criteria:

• Zener voltage: 7.5 V nominal
• Package compatibility: TO-236-3 / SC-59 / SOT-23-3 surface mount
• Impedance (Max): 15 Ohms
• Current - Reverse Leakage @ Vr: 1 µA @ 5 V
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 10 mA
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration:

• Power rating: Minimum 200 mW (higher ratings are acceptable)
• Tolerance: ±6% or better (tighter tolerance acceptable)

Parts are grouped based on exact zener voltage matching at 7.5 V. The BZX84-A7V5,215 and SZBZX84C7V5ET1G meet all primary criteria with enhanced specifications. Parts with 8.2 V zener voltage (SZBZX84C8V2LT3G, SZBZX84C8V2ET1G, SZBZX84C8V2ET3G) do not meet the primary voltage requirement and are not suitable substitutes for the MAZ30750ML.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: BZX84-A7V5,215 (Nexperia USA Inc.)

The BZX84-A7V5,215 is the preferred substitute for the MAZ30750ML. This part maintains identical zener voltage (7.5 V), impedance (15 Ohms), reverse leakage current, and forward voltage specifications. The BZX84-A7V5,215 provides superior tolerance (±1% versus ±6%), increased power rating (250 mW versus 200 mW), and extended operating temperature range (-65°C to 150°C). The part holds Active product status with AEC-Q101 automotive qualification and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Secondary Substitute: SZBZX84C7V5ET1G (onsemi)

The SZBZX84C7V5ET1G serves as an alternative substitute, matching all critical electrical parameters of the MAZ30750ML. This part maintains 7.5 V zener voltage, 15 Ohms impedance, and identical reverse leakage and forward voltage characteristics. The SZBZX84C7V5ET1G offers improved tolerance (±5% versus ±6%), increased power rating (225 mW versus 200 mW), and specified operating temperature range (-65°C to 150°C). The part is Active with AEC-Q101 automotive qualification and ROHS3 compliance.

Non-Suitable Parts:

Parts SZBZX84C8V2LT3G, SZBZX84C8V2ET1G, and SZBZX84C8V2ET3G feature 8.2 V zener voltage and are not suitable substitutes for the MAZ30750ML, which requires 7.5 V nominal voltage. These parts do not meet the primary voltage specification requirement.

Frequently Asked Questions (FAQ)

Q: Can the BZX84-A7V5,215 directly replace the MAZ30750ML in existing designs?

A: Yes. The BZX84-A7V5,215 maintains all critical electrical parameters: 7.5 V zener voltage, 15 Ohms impedance, 1 µA reverse leakage current at 5 V, and 900 mV forward voltage at 10 mA. Package compatibility is identical (TO-236-3 / SC-59 / SOT-23-3). The substitute offers enhanced specifications including tighter tolerance and higher power rating.

Q: What is the difference between the BZX84-A7V5,215 and SZBZX84C7V5ET1G?

A: Both parts maintain 7.5 V zener voltage and identical impedance, reverse leakage, and forward voltage specifications. The BZX84-A7V5,215 provides superior tolerance (±1% versus ±5%) and higher power rating (250 mW versus 225 mW). Both are Active products with automotive qualification and ROHS3 compliance. Selection depends on tolerance and power dissipation requirements of the specific application.

Q: Why are the 8.2 V zener diodes (SZBZX84C8V2 series) listed in the original part data but not recommended as substitutes?

A: The SZBZX84C8V2 series parts feature 8.2 V nominal zener voltage, which does not match the 7.5 V requirement of the MAZ30750ML. Zener voltage is a primary selection criterion and cannot be substituted with a different voltage rating. These parts are listed in the original data as cross-references but are not suitable replacements.

Q: Are there operating temperature considerations when substituting the MAZ30750ML?

A: The MAZ30750ML operating temperature range is not specified in the available data. Both recommended substitutes (BZX84-A7V5,215 and SZBZX84C7V5ET1G) specify -65°C to 150°C operating range, which covers standard industrial and automotive applications. Verify application temperature requirements against these specifications.

Q: What is the significance of the ±1% tolerance on the BZX84-A7V5,215 compared to the ±6% tolerance of the MAZ30750ML?

A: Tolerance defines the acceptable deviation from nominal zener voltage. The BZX84-A7V5,215 with ±1% tolerance provides tighter voltage regulation (±75 mV at 7.5 V) compared to the MAZ30750ML with ±6% tolerance (±450 mV at 7.5 V). This enhanced precision is beneficial for applications requiring stable voltage reference characteristics and is fully compatible with designs originally specified for ±6% tolerance.

Q: Are both substitute parts available in Tape & Reel packaging?

A: Yes. Both the BZX84-A7V5,215 and SZBZX84C7V5ET1G are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Packaging format is compatible with the original MAZ30750ML Surface Mount Mini3-G1 specification.

Q: Do the substitute parts meet RoHS compliance requirements?

A: Yes. Both the BZX84-A7V5,215 and SZBZX84C7V5ET1G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
