Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMBZ6V2ALT3 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 3V (maximum tolerance)
• Voltage - Breakdown (Min): 5.89V
• Voltage - Clamping (Max) @ Ipp: 8.7V
• Current - Peak Pulse (10/1000µs): 2.76A
• Power - Peak Pulse: 24W
• Package / Case: SOT-23-3 (TO-236)
• Mounting Type: Surface Mount
• Type: Zener
• Unidirectional Channels: 2
• Operating Temperature Range: -55°C to 150°C

The MMBZ6V2AL,215 manufactured by Nexperia USA Inc. meets all specified electrical and mechanical parameters, maintaining identical voltage ratings, current handling, power dissipation, and thermal operating range. Both devices share the same base product number (MMBZ6) and package designation, confirming functional equivalence.

Engineering Selection Recommendations

The MMBZ6V2AL,215 is the direct functional equivalent for the obsolete MMBZ6V2ALT3. The Nexperia part carries Active product status and holds ROHS3 compliance, whereas the original onsemi part is RoHS non-compliant and obsolete. The Nexperia device includes AEC-Q101 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Both devices are supplied in tape and reel packaging suitable for automated assembly. The electrical performance, thermal characteristics, and mechanical form factor are identical, enabling direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can MMBZ6V2AL,215 replace MMBZ6V2ALT3 in existing designs?

A: Yes. Both devices share identical electrical specifications across all critical parameters: 3V reverse standoff voltage, 5.89V minimum breakdown voltage, 8.7V maximum clamping voltage, 2.76A peak pulse current, and 24W peak pulse power. The SOT-23-3 package and surface-mount configuration are identical.

Q: What is the difference between the two part numbers?

A: The MMBZ6V2ALT3 is manufactured by onsemi and is obsolete. The MMBZ6V2AL,215 is manufactured by Nexperia USA Inc. and maintains active product status. The Nexperia part includes ROHS3 compliance and AEC-Q101 automotive qualification, whereas the onsemi part does not.

Q: Are there any package compatibility concerns?

A: No. Both parts use the SOT-23-3 (TO-236) package with identical pinout and mechanical dimensions. The Nexperia part is supplied in tape and reel format, standard for automated assembly processes.

Q: What is the operating temperature range for both devices?

A: Both devices operate across -55°C to 150°C. The onsemi specification references junction temperature (TJ), while the Nexperia specification references ambient temperature (TA). The functional operating range remains equivalent.

Q: Are there any compliance differences between the two parts?

A: The MMBZ6V2AL,215 is ROHS3 compliant and AEC-Q101 qualified for automotive applications. The MMBZ6V2ALT3 is RoHS non-compliant. For applications requiring regulatory compliance or automotive qualification, the Nexperia part is the appropriate selection.
