Substitute Part Grouping Explanation

Substitute parts for the P6SMB75CAHM3_A/I are determined by strict equivalence across the following critical parameters:

• Bidirectional Zener TVS diode topology with single channel configuration
• Voltage ratings: 64.1V reverse standoff, 71.3V minimum breakdown, 103V maximum clamping
• Current handling: 5.8A peak pulse (10/1000µs)
• Power dissipation: 600W peak pulse
• Surface mount DO-214AA (SMB) package
• Automotive grade with AEC-Q101 qualification
• Operating temperature range: -65°C to 150°C
• RoHS3 compliance and MSL Level 1

The P6SMB75CAHM3_B/I is classified as a manufacturer-recommended substitute. This part maintains identical electrical specifications and package configuration while differing only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The P6SMB75CAHM3_B/I is the direct substitute for the P6SMB75CAHM3_A/I. Both parts are manufactured by Vishay and maintain identical electrical and mechanical specifications. The primary distinction is product lifecycle status: the P6SMB75CAHM3_A/I is obsolete while the P6SMB75CAHM3_B/I is active in production.

For new designs or ongoing production requiring this TVS diode specification, the P6SMB75CAHM3_B/I is the appropriate selection. Both parts carry AEC-Q101 automotive qualification and ROHS3 compliance, ensuring compatibility with automotive and industrial telecom protection applications. The Tape & Reel packaging of the P6SMB75CAHM3_B/I is standard for high-volume manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB75CAHM3_B/I be used as a direct replacement for the P6SMB75CAHM3_A/I?

A: Yes. The P6SMB75CAHM3_B/I is electrically and mechanically identical to the P6SMB75CAHM3_A/I. Both parts feature the same voltage ratings (64.1V standoff, 103V clamping), current handling (5.8A peak pulse), power dissipation (600W), package type (DO-214AA SMB), and automotive qualifications (AEC-Q101). The substitute is suitable for direct PCB assembly replacement.

Q: What is the difference between the P6SMB75CAHM3_A/I and P6SMB75CAHM3_B/I?

A: The primary differences are product status and packaging format. The P6SMB75CAHM3_A/I is obsolete, while the P6SMB75CAHM3_B/I is active in production. The P6SMB75CAHM3_B/I is supplied in Tape & Reel format, which is standard for automated assembly. All electrical and mechanical specifications are identical.

Q: Are there any thermal or operating condition differences between these parts?

A: No. Both parts operate across the identical temperature range of -65°C to 150°C (junction temperature) and maintain the same electrical performance across this range.

Q: Is the DO-214AA (SMB) package compatible with existing PCB designs?

A: Yes. Both the P6SMB75CAHM3_A/I and P6SMB75CAHM3_B/I use the DO-214AA (SMB) surface mount package. PCB footprints, solder pad layouts, and assembly processes remain unchanged.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both parts carry Automotive grade classification and AEC-Q101 qualification. Both are ROHS3 compliant and carry MSL Level 1 (unlimited moisture sensitivity), meeting automotive and industrial standards.
