Substitute Part Grouping Explanation

Substitution of the MAZ30820ML is determined by the following critical parameters:

Primary Matching Criteria:

Zener voltage: 8.2 V nominal
Package compatibility: TO-236-3 / SC-59 / SOT-23-3 surface mount
Impedance: 15 Ohms maximum
Forward voltage: 900 mV @ 10 mA

Secondary Compatibility Factors:

Power dissipation: Minimum 200 mW (higher ratings acceptable)
Voltage tolerance: ±6% or tighter
Reverse leakage current: 500 nA @ 5 V or lower
Moisture sensitivity: MSL 1 (Unlimited)

Substitute parts are grouped into two categories:

Category A - Direct Electrical Equivalents (8.2 V Zener): Parts maintaining the exact 8.2 V nominal zener voltage with identical or superior electrical specifications and active product status.

Category B - Functional Alternatives (7.5 V Zener): Parts with different nominal zener voltage (7.5 V) that may serve specific circuit requirements where voltage deviation is acceptable within system design parameters.

Engineering Selection Recommendations

Primary Substitute - BZX84-A8V2,215 (Nexperia USA Inc.)

The BZX84-A8V2,215 is the preferred direct substitute for the MAZ30820ML. This part maintains the 8.2 V nominal zener voltage with superior voltage tolerance (±1% versus ±6%), increased power rating (250 mW versus 200 mW), and identical impedance specification. The part is active in production status with AEC-Q101 automotive qualification and ROHS3 compliance, ensuring long-term availability and regulatory alignment. Package compatibility is confirmed as TO-236-3 / SC-59 / SOT-23-3.

Secondary Substitutes - SZBZX84C8V2ET1G, SZBZX84C8V2ET3G, SZBZX84C8V2LT3G (onsemi)

These three onsemi parts provide equivalent 8.2 V zener voltage with active product status and automotive-grade AEC-Q101 qualification. Power rating is 225 mW, exceeding the original 200 mW specification. Voltage tolerance is ±5%, which is tighter than the original ±6%. All three parts share identical electrical parameters and package compatibility. Selection among these three variants depends on specific procurement channel and packaging reel configuration requirements.

Alternative Substitute - SZBZX84C7V5ET1G (onsemi)

The SZBZX84C7V5ET1G operates at 7.5 V nominal zener voltage, representing a 0.7 V reduction from the original 8.2 V specification. This part is suitable only for applications where circuit design permits voltage deviation within the tolerance band. Active product status, AEC-Q101 qualification, and ROHS3 compliance are confirmed. Package compatibility is maintained.

All recommended substitutes feature MSL 1 (Unlimited) moisture sensitivity, matching the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the BZX84-A8V2,215 directly replace the MAZ30820ML without circuit modification?

A: Yes. The BZX84-A8V2,215 maintains the 8.2 V nominal zener voltage, identical impedance (15 Ω), and matching forward voltage characteristics (900 mV @ 10 mA). The increased power rating (250 mW versus 200 mW) and tighter voltage tolerance (±1% versus ±6%) represent improvements in performance margin. Package compatibility is confirmed for TO-236-3 / SC-59 / SOT-23-3 surface mount applications.

Q: What is the difference between the three onsemi 8.2 V substitutes (SZBZX84C8V2ET1G, SZBZX84C8V2ET3G, SZBZX84C8V2LT3G)?

A: All three parts share identical electrical specifications: 8.2 V nominal zener voltage, ±5% tolerance, 225 mW power rating, and 15 Ω impedance. The differences are in packaging reel configuration and manufacturing date codes. Selection should be based on procurement availability and specific packaging requirements from your supplier.

Q: Is the SZBZX84C7V5ET1G a suitable substitute for the MAZ30820ML?

A: The SZBZX84C7V5ET1G operates at 7.5 V nominal zener voltage, which is 0.7 V lower than the original 8.2 V specification. This part is suitable only if your circuit design permits this voltage deviation. The part meets all other electrical and compliance requirements. Verify circuit tolerance specifications before selection.

Q: What compliance certifications are important for substitute selection?

A: All recommended active substitutes carry AEC-Q101 automotive qualification and ROHS3 compliance. These certifications ensure the parts meet automotive industry reliability standards and environmental compliance requirements. The original MAZ30820ML does not list these certifications, making the substitutes suitable for applications requiring automotive-grade components.

Q: Are there any moisture sensitivity differences between the original part and substitutes?

A: No. The MAZ30820ML and all recommended substitutes share MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity constraints for storage, handling, or reflow processes.

Q: What is the inventory status of these substitute parts?

A: BZX84-A8V2,215 has 8132 pieces in stock. SZBZX84C8V2ET1G has 8407 pieces. SZBZX84C8V2ET3G has 986 pieces. SZBZX84C8V2LT3G has 38121 pieces. SZBZX84C7V5ET1G has 1330 pieces. All substitutes are in active production with confirmed availability.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes, all recommended substitutes use identical TO-236-3 / SC-59 / SOT-23-3 surface mount packages with matching pin configurations. PCB footprints and reflow profiles require no modification. Verify that your circuit design tolerates the voltage tolerance specifications of the selected substitute part.
