Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB100AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Unidirectional channel configuration (1 channel required)
• Voltage ratings: Reverse standoff 85.5V, breakdown minimum 95V, clamping maximum 137V
• Peak pulse current: 4.4A (10/1000µs)
• Peak pulse power: 600W
• Package type: DO-214AA (SMB) surface mount
• Operating temperature range: -65°C to 150°C
• Automotive grade with AEC-Q101 qualification
• ROHS3 compliance

The P6SMB100AHM3_B/I is identified as the manufacturer-recommended substitute. This part maintains identical electrical specifications and package configuration while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB100AHM3_B/I is the direct equivalent for the obsolete P6SMB100AHM3_A/I. Both parts share identical electrical specifications, automotive qualification (AEC-Q101), and ROHS3 compliance status. The primary distinction is product lifecycle status: the substitute maintains active manufacturing status with higher inventory availability (1007 pcs vs. 618 pcs), while the original part is obsolete.

For new designs or ongoing production requiring this TVS diode specification, the P6SMB100AHM3_B/I should be selected. The packaging difference (Tape & Reel vs. Bulk) reflects standard distribution formats and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can P6SMB100AHM3_B/I be used as a direct replacement for P6SMB100AHM3_A/I?

A: Yes. Both parts are identical in electrical performance, voltage ratings, current handling, power dissipation, package type (DO-214AA SMB), and automotive qualification. The substitute is the manufacturer-recommended equivalent.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. The P6SMB100AHM3_A/I is obsolete, while the P6SMB100AHM3_B/I is active. The packaging format differs (Bulk vs. Tape & Reel), but this is a distribution consideration only and does not affect circuit performance or PCB assembly compatibility.

Q: Are there any electrical performance differences?

A: No. Both parts maintain identical specifications: 85.5V reverse standoff voltage, 95V minimum breakdown voltage, 137V maximum clamping voltage, 4.4A peak pulse current, and 600W peak pulse power rating.

Q: Is the DO-214AA (SMB) package identical between both parts?

A: Yes. Both parts use the same surface mount package with identical footprint, pin configuration, and mechanical dimensions.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both parts carry Automotive grade classification and AEC-Q101 qualification, meeting automotive industry standards for reliability and quality.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -65°C to 150°C junction temperature range, suitable for automotive and telecom applications.
