Substitute Part Grouping Explanation

Substitute parts for the P6SMB110CAHM3_A/I are identified based on strict electrical and mechanical parameter matching within the TVS diode category. The substitution criteria are:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 94V
• Voltage - Breakdown (Min): 105V
• Voltage - Clamping (Max) @ Ipp: 152V
• Current - Peak Pulse (10/1000µs): 3.9A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The P6SMB110CAHM3_B/I is classified as a direct substitute because it maintains identical electrical performance specifications, automotive-grade qualification, AEC-Q101 certification, and surface mount DO-214AA packaging. The primary distinction is product status: the substitute part is Active, whereas the original part is Obsolete.
