Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ100AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 100V
• Voltage - Breakdown (Min): 111V
• Voltage - Clamping (Max) @ Ipp: 162V
• Current - Peak Pulse (10/1000µs): 3.7A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The SMBJ100AHM3_B/I is identified as a manufacturer-recommended substitute. Both parts share identical electrical specifications and mechanical packaging, with the primary distinction being product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The SMBJ100AHM3_B/I is the direct substitute for the obsolete SMBJ100AHM3_A/I. Both parts maintain identical electrical and thermal specifications, automotive-grade qualification (AEC-Q101), and regulatory compliance (ROHS3, REACH Unaffected). The SMBJ100AHM3_B/I is currently in active production status, ensuring long-term availability and supply chain continuity. The primary difference is packaging format: the substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. Both parts are suitable for telecom applications requiring 100V reverse standoff protection with 600W peak pulse power dissipation capability.

Frequently Asked Questions (FAQ)

Q: Can SMBJ100AHM3_B/I be used as a direct replacement for SMBJ100AHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 100V reverse standoff voltage, 162V maximum clamping voltage, 3.7A peak pulse current, and 600W peak pulse power. Both are housed in DO-214AA (SMB) surface mount packages and qualified to AEC-Q101 automotive standards.

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

A: The primary difference is product status and packaging format. SMBJ100AHM3_A/I is obsolete and supplied in bulk packaging, while SMBJ100AHM3_B/I is active production and supplied in Tape & Reel (TR) format for automated assembly.

Q: Are there any compatibility concerns when switching from SMBJ100AHM3_A/I to SMBJ100AHM3_B/I?

A: No compatibility concerns exist. The electrical performance, thermal characteristics, and mechanical dimensions are identical. The Tape & Reel packaging format is compatible with standard surface mount assembly equipment.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both SMBJ100AHM3_A/I and SMBJ100AHM3_B/I are automotive-grade components qualified to AEC-Q101 and are ROHS3 compliant.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
