Substitute Part Grouping Explanation

Substitution of the P6SMB82AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 70.1V
• Voltage - Breakdown (Min): 77.9V
• Voltage - Clamping (Max) @ Ipp: 113V
• Current - Peak Pulse (10/1000µs): 5.3A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Unidirectional Channels: 1
• Operating Temperature Range: -65°C to 150°C
• AEC-Q101 Qualification
• ROHS3 Compliance

The P6SMB82AHM3_B/I meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB82AHM3_B/I is the direct substitute for the obsolete P6SMB82AHM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, thermal characteristics, and regulatory compliance.

The P6SMB82AHM3_B/I maintains active product status, ensuring ongoing availability and supply chain support. Both parts carry AEC-Q101 automotive qualification and ROHS3 compliance, meeting the same regulatory and quality standards.

The primary difference is packaging format: the original part is supplied in bulk, while the substitute is available in Tape & Reel (TR) format. This packaging difference does not affect electrical performance or functional compatibility and is standard for active production parts.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB82AHM3_B/I be used as a direct replacement for the P6SMB82AHM3_A/I?

A: Yes. Both parts are electrically identical with matching voltage ratings (70.1V standoff, 113V clamping), current ratings (5.3A peak pulse), power dissipation (600W), temperature range (-65 to 150°C), and package type (DO-214AA SMB). Both are AEC-Q101 qualified and ROHS3 compliant.

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

A: The primary difference is product status and packaging. The P6SMB82AHM3_A/I is obsolete and supplied in bulk packaging. The P6SMB82AHM3_B/I is an active product supplied in Tape & Reel (TR) format. Electrical and thermal specifications are identical.

Q: Are there any compatibility concerns when switching from the A/I variant to the B/I variant?

A: No compatibility concerns exist. The DO-214AA (SMB) package footprint is identical for both variants. PCB layout, thermal management, and circuit performance remain unchanged.

Q: Does the Tape & Reel packaging affect component performance?

A: No. Tape & Reel packaging is a delivery and handling format only. It does not affect electrical characteristics, reliability, or performance of the TVS diode.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the P6SMB82AHM3_A/I and P6SMB82AHM3_B/I carry AEC-Q101 qualification, confirming suitability for automotive-grade applications.
