P6SMB8.2AHM3_A/I Equivalent & Substitute Parts

Part Overview

The P6SMB8.2AHM3_A/I is a unidirectional transient voltage suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, designed for telecom applications requiring transient protection. This component features a 7.02V reverse standoff voltage with 12.1V maximum clamping voltage and 49.6A peak pulse current capability in a surface mount DO-214AA (SMB) package. The part is AEC-Q101 qualified for automotive-grade applications and ROHS3 compliant.

The P6SMB8.2AHM3_A/I is classified as obsolete. Locating equivalent or substitute components becomes necessary when original inventory is depleted or when procurement from legacy sources becomes impractical. The substitute part P6SMB8.2AHM3_B/I maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB8.2AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 7.02V
• Voltage - Breakdown (Min): 7.79V
• Voltage - Clamping (Max) @ Ipp: 12.1V
• Current - Peak Pulse (10/1000µs): 49.6A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount
• Operating Temperature Range: -65°C to 150°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The P6SMB8.2AHM3_B/I meets all these criteria identically. The primary distinction between the main part and its substitute is product status (obsolete versus active) and packaging format (unspecified versus Tape & Reel). Both components share the same base product number P6SMB8.2, series designation (P6SMB, TransZorb®), and compliance certifications (ROHS3, REACH Unaffected, EAR99).
