Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMB10J24AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 24V, breakdown minimum of 26.7V, and clamping voltage maximum of 38.9V at peak pulse current
• Current Handling: Peak pulse current of 25.7A at 10/1000µs pulse duration
• Power Dissipation: 1kW peak pulse power rating
• Package: DO-214AA (SMB) surface mount package
• Topology: Unidirectional zener TVS diode with single channel
• Compliance: AEC-Q101 automotive qualification and ROHS3 compliance
• Temperature Range: Operating range of -55°C to 150°C junction temperature

The substitute part must match all electrical parameters and maintain the same package footprint and mounting characteristics. Packaging format (Tape & Reel versus bulk) does not affect electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The SMB10J24AHM3_B/I is the direct equivalent substitute for the obsolete SMB10J24AHM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, package configuration, and automotive-grade certifications.

The primary distinction is product status: SMB10J24AHM3_A/I is obsolete while SMB10J24AHM3_B/I is active. The active status of SMB10J24AHM3_B/I ensures ongoing availability and manufacturing support. Both parts maintain AEC-Q101 automotive qualification and ROHS3 compliance, confirming suitability for automotive and telecom applications requiring transient voltage suppression.

Frequently Asked Questions (FAQ)

Q: Can SMB10J24AHM3_B/I be used as a direct replacement for SMB10J24AHM3_A/I?

A: Yes. Both parts are electrically identical with matching voltage ratings (24V reverse standoff, 26.7V breakdown minimum, 38.9V clamping maximum), current handling (25.7A peak pulse), power dissipation (1kW), and package configuration (DO-214AA SMB surface mount). The difference is product status: SMB10J24AHM3_B/I is active while SMB10J24AHM3_A/I is obsolete.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the DO-214AA (SMB) surface mount package with identical footprints and mounting characteristics. The only packaging difference is format: SMB10J24AHM3_A/I may be supplied in bulk while SMB10J24AHM3_B/I is supplied in Tape & Reel format. This does not affect electrical performance or PCB assembly compatibility.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both SMB10J24AHM3_A/I and SMB10J24AHM3_B/I carry AEC-Q101 automotive qualification and maintain ROHS3 compliance, confirming suitability for automotive-grade applications.

Q: What is the base product number for these parts?

A: The base product number is SMB10J24. Both SMB10J24AHM3_A/I and SMB10J24AHM3_B/I are variants of this base product within the TransZorb® series.
