• Package / Case: TO-236-3, SC-59, SOT-23-3 (physical and electrical compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Moisture Sensitivity Level: 1 (Unlimited) (storage and handling compatibility)

Secondary Compatibility Parameters:

• Power - Max: Equal to or greater than 200 mW
• Impedance (Max): Equal to or less than 20 Ohms
• Current - Reverse Leakage @ Vr: Equal to or less than 3 µA @ 4 V
• Voltage - Forward (Vf) (Max) @ If: Equal to or less than 900 mV @ 10 mA
• Tolerance: ±6% or tighter

Voltage Deviation Allowance: The SZBZX84C6V8ET1G (6.8 V nominal) represents a partial substitute with voltage deviation. This part is included due to its presence in the provided substitute list but operates at a different nominal voltage and requires application-specific validation.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (6.2 V Nominal):

BZX84-A6V2,215 and BZX84-B6V2,215 are direct electrical equivalents to the MAZ30620ML. Both parts are manufactured by Nexperia USA Inc., maintain the 6.2 V nominal Zener voltage, and are packaged in TO-236-3 (SOT-23-3) format. Key advantages include:

• Active product status with established supply chain availability
• Higher maximum power rating (250 mW vs. 200 mW), providing design margin
• Lower impedance (10 Ohms vs. 20 Ohms), improving voltage regulation characteristics
• Tighter voltage tolerance (±1% for BZX84-A6V2,215 and ±2% for BZX84-B6V2,215 vs. ±6%)
• Automotive grade qualification (AEC-Q101) and ROHS3 compliance
• Operating temperature range specified (-65°C ~ 150°C)

Selection between BZX84-A6V2,215 and BZX84-B6V2,215 depends on tolerance requirements. BZX84-A6V2,215 offers superior voltage accuracy (±1%) for precision applications, while BZX84-B6V2,215 provides cost optimization with acceptable ±2% tolerance.

Secondary Substitute (6.8 V Nominal):

SZBZX84C6V8ET1G is a partial substitute with a 6.8 V nominal Zener voltage, representing an 8.1% deviation from the 6.2 V specification. This part is included in the substitute list but operates at a different voltage rating. Selection of this part requires application-specific validation to confirm circuit tolerance to the higher voltage. The part offers:

• Active product status with established supply chain
• Automotive grade qualification (AEC-Q101) and ROHS3 compliance
• Improved reverse leakage characteristics (2 µA vs. 3 µA @ 4 V)
• Operating temperature range specified (-65°C ~ 150°C)

Frequently Asked Questions (FAQ)

Q: Can BZX84-A6V2,215 and BZX84-B6V2,215 be used interchangeably with MAZ30620ML?

A: Yes. Both parts meet all primary matching criteria: 6.2 V nominal Zener voltage, TO-236-3 (SOT-23-3) package, Surface Mount configuration, and MSL 1 rating. Both exceed the original part's electrical specifications in power rating and impedance performance. The primary difference is voltage tolerance (±1% vs. ±2%), which should be evaluated against circuit requirements.

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

A: Impedance (Zzt) directly affects voltage regulation quality. The substitute parts (10 Ohms) provide superior regulation compared to the original part (20 Ohms). Lower impedance results in better voltage stability across varying load conditions, representing an improvement in circuit performance.

Q: Why is SZBZX84C6V8ET1G listed as a substitute if it has a different voltage rating?

A: SZBZX84C6V8ET1G is included in the provided substitute list but operates at 6.8 V nominal, representing an 8.1% voltage deviation from the 6.2 V specification. This part is a partial substitute suitable only for applications where the higher voltage is acceptable. Circuit validation is required before implementation.

Q: Are the Nexperia parts automotive-qualified?

A: Yes. Both BZX84-A6V2,215 and BZX84-B6V2,215 carry Automotive grade designation with AEC-Q101 qualification, indicating compliance with automotive reliability and quality standards.

Q: What is the impact of tighter voltage tolerance on circuit design?

A: Tighter tolerance (±1% for BZX84-A6V2,215) reduces voltage variation across the production range, improving circuit predictability and reducing design margin requirements. This is beneficial for precision voltage regulation applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. BZX84-A6V2,215, BZX84-B6V2,215, and SZBZX84C6V8ET1G are all ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Can the higher power rating of substitute parts cause issues in the original circuit?

A: No. Higher power rating (250 mW vs. 200 mW) indicates greater thermal capacity and does not create circuit incompatibility. The part will operate within its specifications in any circuit designed for the original 200 mW part.

Q: What packaging format is used for these substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) format, standard for automated assembly processes. The physical package remains TO-236-3 (SOT-23-3), maintaining footprint compatibility with the original design.
