Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ26CAHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 26V (±tolerance)
• Voltage - Breakdown (Min): 28.9V
• Voltage - Clamping (Max) @ Ipp: 42.1V
• Current - Peak Pulse (10/1000µs): 14.3A
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The SMBJ26CAHM3_B/I meets all electrical and mechanical requirements for direct substitution. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The SMBJ26CAHM3_B/I is the direct equivalent substitute for the SMBJ26CAHM3_A/I. Both components share identical electrical specifications, thermal operating range, automotive qualification (AEC-Q101), and regulatory compliance (ROHS3, REACH Unaffected).

The SMBJ26CAHM3_B/I carries Active product status, ensuring ongoing manufacturer support and supply availability. This substitution is appropriate for new designs and production continuity where the obsolete SMBJ26CAHM3_A/I is no longer available.

The packaging difference (Tape & Reel versus bulk) does not affect electrical or mechanical compatibility. Selection between packaging formats depends on procurement volume and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can the SMBJ26CAHM3_B/I replace the SMBJ26CAHM3_A/I in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The SMBJ26CAHM3_B/I provides direct substitution with no circuit modifications required.

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

A: The primary differences are product status (Obsolete versus Active) and packaging format (bulk versus Tape & Reel). Electrical specifications, thermal ratings, and automotive qualifications are identical.

Q: Does the Tape & Reel packaging affect PCB assembly compatibility?

A: No. The Tape & Reel format is a supply and handling specification. The component itself maintains the same DO-214AA (SMB) package footprint and soldering characteristics.

Q: Are both parts AEC-Q101 qualified?

A: Yes. Both the SMBJ26CAHM3_A/I and SMBJ26CAHM3_B/I carry AEC-Q101 automotive qualification and are suitable for automotive applications.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
