Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB30CAHM3_A/I is determined by strict equivalence across the following electrical and mechanical parameters:

Voltage specifications: Reverse standoff voltage of 25.6V (typical), breakdown voltage minimum of 28.5V, and maximum clamping voltage of 41.4V at peak pulse current.

Current and power ratings: Peak pulse current of 14.5A at 10/1000µs pulse duration and peak pulse power of 600W.

Package and mounting: DO-214AA (SMB) surface mount package.

Environmental and compliance requirements: Operating temperature range of -65°C to 150°C, automotive grade classification, AEC-Q101 qualification, and ROHS3 compliance.

Substitute parts must maintain identical electrical performance and physical form factor to ensure direct replacement without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB30CAHM3_B/I is the direct substitute for the obsolete P6SMB30CAHM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, package form factor, and compliance certifications.

The primary distinction is product status: the P6SMB30CAHM3_A/I is obsolete, while the P6SMB30CAHM3_B/I maintains active production status. The substitute part carries AEC-Q101 automotive qualification and ROHS3 compliance, meeting the same regulatory and quality requirements as the original part.

For applications requiring the P6SMB30CAHM3_A/I, the P6SMB30CAHM3_B/I provides equivalent performance without circuit modification or PCB redesign. The difference in packaging format (tape & reel for the substitute versus unspecified for the main part) does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB30CAHM3_B/I be used as a direct replacement for the P6SMB30CAHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical, with matching voltage ratings (25.6V standoff, 41.4V clamping), current specifications (14.5A peak pulse), power rating (600W), operating temperature range (-65°C to 150°C), and DO-214AA (SMB) surface mount package. No circuit redesign or PCB layout modification is required.

Q: What is the difference between the P6SMB30CAHM3_A/I and P6SMB30CAHM3_B/I?

A: The primary difference is product status. The P6SMB30CAHM3_A/I is obsolete, while the P6SMB30CAHM3_B/I is in active production. The substitute part is supplied in tape & reel packaging format. All electrical and mechanical specifications remain identical.

Q: Are both parts AEC-Q101 qualified?

A: Yes. Both the P6SMB30CAHM3_A/I and P6SMB30CAHM3_B/I carry AEC-Q101 automotive qualification and are ROHS3 compliant, meeting automotive-grade reliability and environmental standards.

Q: Does the packaging format affect compatibility?

A: No. The packaging format difference (tape & reel for the substitute) is a supply and handling consideration only. The physical component form factor and electrical performance remain unchanged. Both parts use the DO-214AA (SMB) surface mount package.

Q: What applications are these parts suitable for?

A: Both parts are specified for telecom applications requiring transient voltage suppression. The automotive-grade classification and AEC-Q101 qualification indicate suitability for automotive and industrial environments where transient protection is required.
