Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ60AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 60V (±tolerance)
• Voltage - Clamping (Max) @ Ipp: 96.8V
• Current - Peak Pulse (10/1000µs): 6.2A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Unidirectional Channels: 1
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Automotive Grade: AEC-Q101 qualified
• RoHS Compliance: ROHS3 Compliant

The SMBJ60AHM3_B/I is identified as the manufacturer-recommended substitute, maintaining identical electrical specifications and package configuration while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The SMBJ60AHM3_B/I is the direct equivalent for the obsolete SMBJ60AHM3_A/I. Both components are manufactured by Vishay and maintain identical electrical and thermal specifications. The primary distinction is product status: SMBJ60AHM3_A/I is obsolete, while SMBJ60AHM3_B/I is active and maintains current manufacturing support.

Both parts carry automotive-grade qualification (AEC-Q101) and ROHS3 compliance, ensuring suitability for regulated applications. The SMBJ60AHM3_B/I is supplied in Tape & Reel packaging, which is standard for production environments and offers improved handling and automated assembly compatibility compared to bulk packaging.

For new designs or component replenishment, SMBJ60AHM3_B/I is the appropriate selection. For existing inventory management or legacy system support, SMBJ60AHM3_B/I provides a direct functional replacement with enhanced supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can SMBJ60AHM3_B/I be used as a direct replacement for SMBJ60AHM3_A/I?

A: Yes. Both components are electrically and mechanically identical, with matching voltage ratings (60V standoff, 96.8V clamping), current specifications (6.2A peak pulse), power dissipation (600W), package configuration (DO-214AA SMB), and operating temperature range (-55°C to 150°C). The primary difference is product status and packaging format.

Q: What is the difference between the packaging formats?

A: SMBJ60AHM3_A/I is supplied in bulk packaging, while SMBJ60AHM3_B/I is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for production assembly and automated pick-and-place equipment. Both formats contain identical components.

Q: Are both parts automotive-qualified?

A: Yes. Both SMBJ60AHM3_A/I and SMBJ60AHM3_B/I carry AEC-Q101 automotive qualification and are ROHS3 compliant, meeting regulatory requirements for automotive and industrial applications.

Q: Why is SMBJ60AHM3_A/I listed as obsolete?

A: Product obsolescence typically reflects manufacturing discontinuation by the supplier. SMBJ60AHM3_B/I remains in active production and is the recommended alternative for continued supply and support.

Q: Are there any performance differences between these parts?

A: No. Both components have identical electrical performance specifications, thermal characteristics, and reliability ratings. Selection should be based on availability, packaging requirements, and supply chain considerations.
