Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ64D-M3/H is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 64V
• Voltage - Clamping (Max) @ Ipp: 102V maximum
• Current - Peak Pulse (10/1000µs): 5.88A nominal
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C (TJ)
• RoHS Status: ROHS3 Compliant

The SMBJ64A-E3/52 qualifies as a manufacturer-recommended substitute because it maintains identical reverse standoff voltage, equivalent clamping voltage performance, compatible peak pulse current rating, identical package specification, and matching environmental and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ64D-M3/H and SMBJ64A-E3/52 are active production components manufactured by Vishay General Semiconductor - Diodes Division. Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, meeting current regulatory and environmental requirements. The SMBJ64A-E3/52 offers significantly higher inventory availability (45,400 pieces) compared to the SMBJ64D-M3/H (1,185 pieces), making it suitable for applications where supply chain continuity is a priority. Component selection should be based on procurement lead time, inventory requirements, and application-specific performance margins within the specified electrical parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can SMBJ64A-E3/52 be used as a direct replacement for SMBJ64D-M3/H?

A: Yes. Both parts share identical reverse standoff voltage (64V), equivalent clamping voltage performance (102V vs. 103V), compatible peak pulse current ratings (5.88A vs. 5.8A), and identical DO-214AA SMB package specifications. Both are ROHS3 compliant with MSL Level 1 ratings.

Q: What are the key electrical differences between these parts?

A: The voltage breakdown minimum differs slightly (72.2V vs. 71.1V), and clamping voltage maximum varies by 1V (102V vs. 103V). Peak pulse current is nominally equivalent (5.88A vs. 5.8A). These variations remain within the functional tolerance band for general-purpose TVS diode applications.

Q: Are there any package or mounting differences?

A: No. Both parts use the DO-214AA (SMB) surface-mount package with identical mechanical and thermal characteristics.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Which part should be selected for new designs?

A: Selection should be based on inventory availability, procurement lead time, and supply chain strategy. The SMBJ64A-E3/52 offers higher stock levels. Both parts are suitable for new designs meeting the specified electrical and environmental requirements.
