MMBZ6V2AL-7-F Equivalent & Substitute Parts

Part Overview

The MMBZ6V2AL-7-F is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 3V reverse standoff voltage, 8.7V maximum clamping voltage, and 2.76A peak pulse current capability in a compact SOT-23-3 package. The part is currently listed as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Substitute Part Grouping Explanation

Substitution of the MMBZ6V2AL-7-F is determined by strict equivalence across the following critical parameters: reverse standoff voltage (3V), breakdown voltage minimum (5.89V), clamping voltage maximum (8.7V), peak pulse current (2.76A), package type (SOT-23-3), and surface-mount configuration. All substitute parts must maintain these electrical specifications within the defined tolerances and operate within the specified temperature range. Mechanical compatibility is ensured through identical package designation and pin configuration. RoHS3 compliance and MSL-1 moisture sensitivity are required for all substitutes.

Engineering Selection Recommendations

MMBZ6V2ALT1G and MMBZ6V2AL,215 provide direct electrical equivalence to the obsolete MMBZ6V2AL-7-F with identical clamping voltage (8.7V) and peak pulse current (2.76A) specifications. MMBZ6V2ALT1G is available in standard commercial packaging, while MMBZ6V2AL,215 includes automotive-grade qualification (AEC-Q101) with extended temperature operating range. SZMMBZ6V2ALT1G offers the same electrical performance with automotive qualification and tape & reel packaging.

MMBZ5V6AL,215 provides near-equivalent performance with slightly lower clamping voltage (8V) and higher peak pulse current (3A), suitable for applications where marginal voltage differences are acceptable. ESDA5V3L from STMicroelectronics offers significantly higher peak pulse power (300W) but lacks specified clamping voltage and peak pulse current data, limiting direct comparison.

For production continuity, MMBZ6V2AL,215 (Nexperia) is recommended as the primary substitute due to exact electrical parameter matching, automotive qualification, and active product status. MMBZ6V2ALT1G (onsemi) serves as a secondary option for non-automotive applications requiring standard commercial packaging.

Frequently Asked Questions (FAQ)

Q: Can MMBZ6V2ALT1G directly replace MMBZ6V2AL-7-F? A: Yes. MMBZ6V2ALT1G maintains identical electrical specifications: 3V reverse standoff, 5.89V breakdown minimum, 8.7V clamping maximum, and 2.76A peak pulse current. Both use SOT-23-3 packaging. The primary difference is product status (active vs. obsolete) and operating temperature range (-55 to 150°C vs. -65 to 150°C).

Q: What is the difference between MMBZ6V2ALT1G and SZMMBZ6V2ALT1G? A: Both are onsemi products with identical electrical specifications. SZMMBZ6V2ALT1G includes automotive-grade qualification (AEC-Q101) and is supplied in tape & reel packaging, while MMBZ6V2ALT1G is available in cut tape and digi-reel options without automotive certification.

Q: Is MMBZ5V6AL,215 a suitable substitute? A: MMBZ5V6AL,215 is a near-equivalent with compatible reverse standoff voltage (3V) and similar clamping voltage (8V vs. 8.7V). However, it specifies higher peak pulse current (3A vs. 2.76A). Use only if circuit design tolerates the 0.7V clamping voltage difference and higher current capability.

Q: Why does ESDA5V3L show 300W peak pulse power instead of 24W? A: ESDA5V3L is a different TVS diode series with enhanced power dissipation capability. Critical electrical parameters (clamping voltage and peak pulse current) are not specified in available data, preventing full equivalence verification. This part should be evaluated only if higher power handling is required.

Q: Are all substitutes RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL-1 moisture sensitivity rating, matching the original MMBZ6V2AL-7-F specifications.

Q: What packaging options are available for substitutes? A: MMBZ6V2ALT1G is supplied in cut tape and digi-reel formats. SZMMBZ6V2ALT1G, MMBZ5V6AL,215, and MMBZ6V2AL,215 are available in tape & reel packaging. Select based on assembly equipment compatibility and procurement volume requirements.
