Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMB10J15AHM3_A/I is determined by strict electrical and mechanical parameter matching within the TVS diode category. The following parameters establish substitution validity:

• Voltage - Reverse Standoff: 15V (nominal)
• Voltage - Breakdown (Min): 16.7V
• Voltage - Clamping (Max) @ Ipp: 24.4V
• Current - Peak Pulse (10/1000µs): 41A
• Power - Peak Pulse: 1000W
• Package / Case: DO-214AA (SMB)
• Operating Temperature Range: -55°C ~ 150°C
• Automotive Grade and AEC-Q101 Qualification

The SMB10J15AHM3_B/I meets all these criteria and shares the identical base product number (SMB10J15), confirming direct substitution compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SMB10J15AHM3_B/I is the direct equivalent for the obsolete SMB10J15AHM3_A/I. Both components share identical electrical specifications, automotive-grade qualification, and AEC-Q101 certification. The primary distinction is product status: the SMB10J15AHM3_B/I maintains active production status with confirmed inventory availability, while the original part is obsolete. The packaging difference (Tape & Reel versus bulk) does not affect electrical performance or PCB-level compatibility. Selection of the SMB10J15AHM3_B/I ensures continued access to a functionally identical component with ongoing manufacturer support and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can SMB10J15AHM3_B/I be used as a direct replacement for SMB10J15AHM3_A/I?

A: Yes. Both parts are identical in all electrical parameters, thermal characteristics, and mechanical specifications. The SMB10J15AHM3_B/I is the active production equivalent.

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

A: The suffix designations (_A/I versus _B/I) indicate manufacturing lot or revision codes. The electrical and functional specifications remain unchanged. The SMB10J15AHM3_B/I is currently in active production.

Q: Are there packaging compatibility concerns?

A: No. Both parts use the DO-214AA (SMB) surface mount package. The difference in packaging format (Tape & Reel for the substitute versus bulk for the original) does not affect PCB assembly or electrical performance.

Q: Does the substitute part maintain automotive and compliance certifications?

A: Yes. The SMB10J15AHM3_B/I carries identical Automotive Grade designation and AEC-Q101 qualification, along with ROHS3 compliance and REACH unaffected status.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution is valid when the following parameters match: 15V reverse standoff voltage, 16.7V minimum breakdown voltage, 24.4V maximum clamping voltage, 41A peak pulse current, and 1000W peak pulse power rating.
