Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ16AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 16V (±tolerance)
• Voltage - Breakdown (Min): 17.8V
• Voltage - Clamping (Max) @ Ipp: 26V
• Current - Peak Pulse (10/1000µs): 23.1A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Automotive Grade and AEC-Q101 Qualification

The SMBJ16AHM3_B/I is 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 SMBJ16AHM3_B/I is the direct functional equivalent of the SMBJ16AHM3_A/I. Both components are manufactured by Vishay and maintain identical electrical performance specifications, automotive-grade qualification, and AEC-Q101 certification. The primary distinction is product status: the SMBJ16AHM3_A/I is obsolete, while the SMBJ16AHM3_B/I maintains active production status. For new designs or component replenishment, the SMBJ16AHM3_B/I is the appropriate selection. The packaging difference (bulk versus Tape & Reel) does not affect electrical or mechanical compatibility and is a procurement consideration only.

Frequently Asked Questions (FAQ)

Q: Can the SMBJ16AHM3_B/I be used as a direct replacement for the SMBJ16AHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical, with matching voltage ratings (16V standoff, 26V clamping), current ratings (23.1A peak pulse), power dissipation (600W), package configuration (DO-214AA SMB), and automotive qualifications (AEC-Q101). The SMBJ16AHM3_B/I is the active production equivalent.

Q: What is the difference between the SMBJ16AHM3_A/I and SMBJ16AHM3_B/I?

A: The SMBJ16AHM3_A/I is classified as obsolete, while the SMBJ16AHM3_B/I is active. The packaging format differs (bulk versus Tape & Reel), but electrical specifications and performance are identical.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both components share the same DO-214AA (SMB) surface mount package, identical pinout, and equivalent electrical characteristics. PCB layout and circuit design require no modification.

Q: Does the Tape & Reel packaging of the SMBJ16AHM3_B/I affect performance?

A: No. Packaging format is a supply chain and assembly consideration only. It does not affect electrical performance, reliability, or functional characteristics of the component.

Q: Are both parts automotive-grade and AEC-Q101 qualified?

A: Yes. Both the SMBJ16AHM3_A/I and SMBJ16AHM3_B/I carry automotive-grade classification and AEC-Q101 qualification, meeting automotive reliability and quality standards.
