Substitute Part Grouping Explanation

Substitution eligibility for the P6SMB13AHM3_A/I is determined by strict equivalence across the following critical parameters:

  • Voltage - Reverse Standoff (Typ): 11.1V
  • Voltage - Breakdown (Min): 12.4V
  • Voltage - Clamping (Max) @ Ipp: 18.2V
  • Current - Peak Pulse (10/1000µs): 33A
  • Power - Peak Pulse: 600W
  • Package / Case: DO-214AA (SMB)
  • Operating Temperature Range: -65°C ~ 150°C (TJ)
  • Automotive Grade and AEC-Q101 Qualification

The P6SMB13AHM3_B/I is identified as a manufacturer-recommended substitute. This part maintains identical electrical specifications and thermal performance while differing only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Engineering Selection Recommendations

The P6SMB13AHM3_B/I is the direct substitute for the obsolete P6SMB13AHM3_A/I. Both parts are manufactured by Vishay and maintain identical electrical and thermal specifications. The P6SMB13AHM3_B/I carries Active product status, ensuring continued availability and manufacturing support.

Both parts meet automotive-grade requirements and hold AEC-Q101 qualification, confirming suitability for automotive and telecom applications requiring transient overvoltage protection. ROHS3 compliance and equivalent environmental specifications ensure regulatory alignment.

The primary distinction is packaging format: the P6SMB13AHM3_B/I is supplied in Tape & Reel format, which is standard for high-volume production environments. Component selection should be based on procurement volume and assembly line requirements.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB13AHM3_B/I be used as a direct replacement for the P6SMB13AHM3_A/I?

A: Yes. Both parts are electrically and thermally identical, with matching voltage ratings (11.1V reverse standoff, 18.2V clamping), current ratings (33A peak pulse), and power dissipation (600W). Both are housed in DO-214AA (SMB) surface mount packages and meet automotive AEC-Q101 qualification.

Q: What is the difference between the two part numbers?

A: The primary difference is product status and packaging format. The P6SMB13AHM3_A/I is obsolete, while the P6SMB13AHM3_B/I is active. The P6SMB13AHM3_B/I is supplied in Tape & Reel format, standard for production assembly.

Q: Are there any thermal or operating temperature differences?

A: No. Both parts operate across the identical temperature range of -65°C to 150°C (junction temperature) and maintain the same thermal performance characteristics.

Q: Do both parts meet the same compliance and qualification standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and hold AEC-Q101 automotive qualification. Both are suitable for telecom and automotive applications requiring transient voltage suppression.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Identical package specifications (DO-214AA/SMB) and mounting type (surface mount) ensure mechanical and electrical interchangeability on the same PCB layout without design modifications.
