Substitute Part Grouping Explanation

Substitution eligibility for the TPC11AHM3/86A is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 9.4V (Typ)
• Voltage - Breakdown: 10.5V (Min)
• Voltage - Clamping: 15.6V (Max) @ Ipp
• Current - Peak Pulse: 96.2A (10/1000µs)
• Power - Peak Pulse: 1500W
• Package / Case: TO-277, 3-PowerDFN
• Mounting Type: Surface Mount
• Operating Temperature: -65°C to 185°C (TJ)
• Automotive Grade and AEC-Q101 Qualification

The substitute part TPC11AHM3_A/H maintains identical electrical performance and mechanical specifications, with the primary distinction being active product status versus the obsolete status of the original part.
