Substitute Part Grouping Explanation

Substitution of the TPC10AHM3/86A is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 8.55V (Typ)
• Voltage - Breakdown: 9.5V (Min)
• Voltage - Clamping: 14.5V (Max) @ Ipp
• Current - Peak Pulse: 103A (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 TPC10AHM3_A/H maintains identical electrical specifications and automotive qualifications. The primary distinction is packaging format (Tape & Reel vs. bulk) and product status (Active vs. Obsolete).
