Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB62AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 53V
• Voltage - Breakdown (Min): 58.9V
• Voltage - Clamping (Max) @ Ipp: 85V
• Current - Peak Pulse (10/1000µs): 7.1A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Unidirectional Channels: 1
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Automotive Grade and AEC-Q101 Qualification

The P6SMB62AHM3_B/I is a direct substitute, maintaining identical electrical specifications and automotive qualifications while differing only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The P6SMB62AHM3_B/I is the direct equivalent for the obsolete P6SMB62AHM3_A/I. Both parts maintain identical electrical performance specifications and automotive-grade qualifications including AEC-Q101 certification. The primary distinction is product status: the _B/I variant is currently in active production, ensuring long-term availability and supply chain continuity.

For new designs or system refreshes, the P6SMB62AHM3_B/I should be selected. For legacy system support where the original _A/I variant is required, the _B/I provides full functional and electrical compatibility while offering improved availability. Both parts comply with ROHS3 and REACH requirements, supporting modern environmental and regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB62AHM3_B/I be used as a direct replacement for the P6SMB62AHM3_A/I?

A: Yes. Both parts are electrically identical with matching voltage ratings (53V standoff, 85V clamping), current ratings (7.1A peak pulse), power dissipation (600W), and operating temperature ranges (-65°C to 150°C). Both are packaged in DO-214AA (SMB) and qualified to AEC-Q101 automotive standards.

Q: What is the difference between the _A/I and _B/I variants?

A: The primary differences are product status and packaging format. The _A/I is obsolete, while the _B/I is in active production. The _B/I is supplied in Tape & Reel format, which is standard for high-volume manufacturing. Electrical specifications and performance are identical.

Q: Are there any compatibility concerns when switching from P6SMB62AHM3_A/I to P6SMB62AHM3_B/I?

A: No compatibility concerns exist. Both parts use the same DO-214AA (SMB) surface mount package, identical pinout, and equivalent electrical characteristics. PCB layout and circuit design require no modifications.

Q: Do both parts meet automotive and environmental compliance requirements?

A: Yes. Both the P6SMB62AHM3_A/I and P6SMB62AHM3_B/I are automotive-grade components qualified to AEC-Q101. Both are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What should be considered when sourcing the P6SMB62AHM3_B/I?

A: The _B/I variant is supplied in Tape & Reel (TR) packaging, which is optimized for automated assembly processes. Verify that your procurement and assembly processes support this packaging format. Inventory availability of the active _B/I variant is typically superior to the obsolete _A/I.
