Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ10AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 10V (±5% tolerance)
• Voltage - Clamping (Max) @ Ipp: 17V
• Current - Peak Pulse (10/1000µs): 35.3A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Type: Unidirectional Zener
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Automotive Grade with AEC-Q101 Qualification
• RoHS3 Compliance

The SMBJ10AHM3_B/I is classified as a manufacturer-recommended substitute because it maintains identical electrical specifications, thermal performance, package configuration, and automotive qualification requirements while offering active product status.

Parameter Comparison

Engineering Selection Recommendations

The SMBJ10AHM3_B/I is the direct equivalent for the obsolete SMBJ10AHM3_A/I. Both components are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical and thermal characteristics. The primary distinction is product status: SMBJ10AHM3_A/I is obsolete while SMBJ10AHM3_B/I maintains active status, ensuring continued availability and supply chain support.

Both parts maintain automotive-grade qualification with AEC-Q101 certification and ROHS3 compliance, meeting all regulatory and quality requirements for telecom applications. The packaging difference (bulk versus Tape & Reel) does not affect functional compatibility and represents a standard supply chain variation.

Frequently Asked Questions (FAQ)

Q: Can SMBJ10AHM3_B/I be used as a direct replacement for SMBJ10AHM3_A/I?

A: Yes. Both components are electrically and mechanically identical with matching voltage ratings (10V standoff, 17V clamping), current handling (35.3A peak pulse), power dissipation (600W), package configuration (DO-214AA SMB), and automotive qualification (AEC-Q101). The primary difference is product status.

Q: What is the significance of the packaging difference between these parts?

A: SMBJ10AHM3_A/I is supplied in bulk packaging while SMBJ10AHM3_B/I is supplied in Tape & Reel (TR) format. This is a standard supply chain variation that does not affect component functionality or performance. Selection depends on manufacturing process requirements and volume needs.

Q: Are both parts suitable for automotive applications?

A: Yes. Both SMBJ10AHM3_A/I and SMBJ10AHM3_B/I carry automotive-grade classification with AEC-Q101 qualification, meeting automotive industry standards for reliability and quality.

Q: Why is SMBJ10AHM3_A/I marked as obsolete?

A: Obsolescence indicates the manufacturer has discontinued active production. SMBJ10AHM3_B/I represents the active equivalent, ensuring continued availability and supply chain support for new designs and production requirements.

Q: Do these parts meet environmental compliance requirements?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
