Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB82AHM3_A/H is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 70V ± tolerance
• Voltage - Clamping (Max) @ Ipp: 113V
• Current - Peak Pulse (10/1000µs): 5.3A
• Power - Peak Pulse: 600W
• Unidirectional channel configuration

Mechanical Parameters (Must Match):

• Package / Case: DO-214AA (SMB or SMBJ variant)
• Mounting Type: Surface Mount

Compliance & Qualification (Must Match or Exceed):

• Automotive Grade
• AEC-Q101 Qualification
• RoHS3 Compliance

The identified substitute parts maintain electrical performance within the specified operating envelope and preserve mechanical compatibility with existing PCB layouts and assembly processes. Product status transitions from obsolete to active availability improve supply chain reliability.

Engineering Selection Recommendations

P6SMB82AHM3_B/H (Vishay - Recommended Primary Substitute)

This part represents the direct active-production equivalent from the original manufacturer. Electrical parameters are identical to the obsolete P6SMB82AHM3_A/H. The transition from tape & reel packaging to bulk packaging does not affect electrical performance or mechanical compatibility. Maintains full automotive qualification and AEC-Q101 certification. Inventory availability (849 pcs) supports production requirements.

SMBJE70AH (Eaton - Alternative Substitute)

This part provides functional equivalence with cross-manufacturer compatibility. Electrical performance matches the primary specification across all critical parameters. The SMBJ package variant (DO-214AA SMBJ) maintains mechanical compatibility with SMB footprints. Operating temperature range is reduced to -55°C ~ 150°C, which may be a constraint in applications requiring the full -65°C lower limit. Automotive grade and AEC-Q101 qualification are maintained. Tape & reel packaging supports automated assembly. Higher inventory availability (1052 pcs) provides supply chain flexibility.

Frequently Asked Questions (FAQ)

Q: Can P6SMB82AHM3_B/H be used as a direct replacement for P6SMB82AHM3_A/H?

A: Yes. The P6SMB82AHM3_B/H is the active-production equivalent with identical electrical specifications, package footprint, and automotive qualifications. The only difference is packaging format (bulk vs. tape & reel), which does not affect component performance or PCB assembly compatibility.

Q: What is the difference between SMB and SMBJ package designations?

A: Both SMB and SMBJ refer to the DO-214AA package form factor. The designations indicate different manufacturer conventions but maintain identical mechanical dimensions and PCB footprint compatibility. SMBJ is the Eaton designation; SMB is the Vishay designation.

Q: Is SMBJE70AH suitable for applications requiring -65°C operation?

A: The SMBJE70AH operating temperature range is -55°C ~ 150°C. Applications requiring -65°C minimum operating temperature must use P6SMB82AHM3_B/H, which specifies -65°C ~ 150°C.

Q: Are all substitute parts automotive-grade and AEC-Q101 qualified?

A: Yes. Both P6SMB82AHM3_B/H and SMBJE70AH carry automotive grade classification and AEC-Q101 qualification, meeting automotive reliability and qualification standards.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching voltage ratings (70V reverse standoff, 113V clamping), current rating (5.3A peak pulse), power dissipation (600W), and unidirectional channel configuration. All identified substitutes meet these criteria.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the application does not require the extended lower temperature limit of -65°C. For applications operating at -55°C or above, both substitutes are fully interchangeable. For applications requiring -65°C operation, use P6SMB82AHM3_B/H.
