Substitute Part Grouping Explanation

Substitution for the P6SMB30AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 25.6V
• Voltage - Breakdown (Min): 28.5V
• Voltage - Clamping (Max) @ Ipp: 41.4V
• Current - Peak Pulse (10/1000µs): 14.5A
• 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 substitute part P6SMB30AHM3_B/I maintains identical electrical and mechanical specifications while differing only in packaging format (Tape & Reel) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P6SMB30AHM3_B/I is the direct substitute for the obsolete P6SMB30AHM3_A/I. Both parts maintain identical electrical performance specifications and automotive-grade qualifications (AEC-Q101). The primary distinction is product status and packaging format. The P6SMB30AHM3_B/I is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts comply with ROHS3 and REACH requirements, supporting modern regulatory compliance standards.

Frequently Asked Questions (FAQ)

Q: Can P6SMB30AHM3_B/I be used as a direct replacement for P6SMB30AHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters including voltage ratings, current handling, clamping characteristics, and operating temperature range. The primary difference is packaging format and product status.

Q: What is the difference between the packaging formats?

A: P6SMB30AHM3_A/I is supplied in bulk packaging, while P6SMB30AHM3_B/I is supplied in Tape & Reel (TR) format. Both use the same DO-214AA (SMB) component package for PCB mounting.

Q: Are both parts automotive-grade qualified?

A: Yes. Both P6SMB30AHM3_A/I and P6SMB30AHM3_B/I carry automotive-grade classification with AEC-Q101 qualification, meeting automotive industry reliability and quality standards.

Q: Why is P6SMB30AHM3_A/I listed as obsolete?

A: The A/I variant has been discontinued by the manufacturer. The P6SMB30AHM3_B/I variant remains in active production and is the recommended source for new orders and ongoing supply requirements.

Q: Do these parts require any design modifications when substituting?

A: No design modifications are required. The electrical and mechanical specifications are identical, and both parts use the same DO-214AA (SMB) surface mount package.
