Substitute Part Grouping Explanation

The TPC36AHM3/86A has been identified as obsolete. The substitute part TPC36AHM3_A/H is classified as active and maintains identical electrical and mechanical specifications. Substitution is valid based on the following critical parameters:

• Voltage - Reverse Standoff (Typ): 30.8V
• Voltage - Breakdown (Min): 34.2V
• Voltage - Clamping (Max) @ Ipp: 49.9V
• Current - Peak Pulse (10/1000µs): 30.1A
• Power - Peak Pulse: 1500W
• Package / Case: TO-277, 3-PowerDFN
• Mounting Type: Surface Mount
• Operating Temperature Range: -65°C ~ 185°C (TJ)
• Automotive Grade and AEC-Q101 Qualification

The substitute part differs only in packaging format (Tape & Reel vs. standard packaging) and product status (Active vs. Obsolete), with no electrical or thermal performance variations.

Parameter Comparison

Engineering Selection Recommendations

The TPC36AHM3_A/H is a direct functional equivalent to the obsolete TPC36AHM3/86A. Both parts maintain identical electrical performance specifications, thermal operating range, and automotive-grade certifications including AEC-Q101 qualification. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Selection of TPC36AHM3_A/H is appropriate for applications requiring the specified 30.8V standoff voltage, 49.9V clamping voltage, and 30.1A peak pulse current protection. The Tape & Reel packaging format of the substitute part is standard for high-volume surface mount assembly processes and does not impact electrical or thermal performance.

Frequently Asked Questions (FAQ)

Q: Can TPC36AHM3_A/H be used as a direct replacement for TPC36AHM3/86A?

A: Yes. Both parts are identical in electrical specifications, thermal performance, package type (TO-277, 3-PowerDFN), and automotive qualifications. The only difference is product status and packaging format.

Q: What is the significance of the packaging format difference (standard vs. Tape & Reel)?

A: Tape & Reel (TR) packaging is the standard format for automated surface mount assembly. This format does not affect component performance or compatibility with TO-277 surface mount footprints. Standard packaging and Tape & Reel packaging contain identical components.

Q: Are both parts suitable for automotive applications?

A: Yes. Both TPC36AHM3/86A and TPC36AHM3_A/H carry automotive-grade classification and AEC-Q101 qualification, meeting automotive industry reliability and quality standards.

Q: What are the critical electrical parameters for substitution?

A: The critical parameters that must match for valid substitution are: Voltage - Reverse Standoff (30.8V), Voltage - Breakdown (34.2V minimum), Voltage - Clamping (49.9V maximum), Current - Peak Pulse (30.1A), and Power - Peak Pulse (1500W).

Q: Is the operating temperature range identical between both parts?

A: Yes. Both parts operate across the identical temperature range of -65°C to 185°C (junction temperature), ensuring thermal compatibility in all specified applications.
