Substitute Part Grouping Explanation

Substitution eligibility for the TPC12AHM3/86A is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 10.2V
• Voltage - Breakdown (Min): 11.4V
• Voltage - Clamping (Max) @ Ipp: 16.7V
• Current - Peak Pulse (10/1000µs): 89.8A
• Power - Peak Pulse: 1500W
• Operating Temperature Range: -65°C to 185°C (TJ)
• Package / Case: TO-277, 3-PowerDFN
• Mounting Type: Surface Mount
• Grade: Automotive
• Qualification: AEC-Q101

The substitute part TPC12AHM3_A/H maintains identical electrical specifications and mechanical compatibility while differing only in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The TPC12AHM3_A/H is a direct functional equivalent to the TPC12AHM3/86A. Both components are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical performance specifications across all critical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and power dissipation.

Both parts carry Automotive grade qualification and AEC-Q101 certification, confirming suitability for automotive transient protection applications. Both achieve ROHS3 compliance and REACH unaffected status.

The primary distinction is product lifecycle status: TPC12AHM3/86A is Obsolete, while TPC12AHM3_A/H is Active. The Active status of TPC12AHM3_A/H ensures ongoing manufacturing availability and supply chain continuity. The packaging difference (Tape & Reel versus bulk) reflects standard distribution formats and does not affect electrical or mechanical compatibility.
