TPC7.5AHM3/86A Equivalent & Substitute Parts

Part Overview

The TPC7.5AHM3/86A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component is designed for transient overvoltage protection in automotive applications, featuring a 6.4V reverse standoff voltage and 11.3V maximum clamping voltage. The part is currently classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPC7.5AHM3/86A is determined by strict equivalence across the following critical parameters:

Voltage specifications must match exactly: Reverse Standoff Voltage of 6.4V (Typ), Breakdown Voltage minimum of 7.13V, and Clamping Voltage maximum of 11.3V at peak pulse current.

Current and power ratings must be identical: Peak Pulse Current of 133A (10/1000µs) and Peak Pulse Power of 1500W.

Physical and electrical configuration must be preserved: Unidirectional topology (1 channel), Zener type, and TO-277A (SMPC) surface mount package.

Compliance and qualification standards must be maintained: Automotive grade, AEC-Q101 qualification, ROHS3 compliance, and operating temperature range of -65°C to 185°C.

The substitute part TPC7.5AHM3_A/H meets all these criteria and is classified as an active product, providing direct functional and mechanical compatibility with the obsolete TPC7.5AHM3/86A.

Parameter Comparison

Engineering Selection Recommendations

The TPC7.5AHM3_A/H is the direct active equivalent for the obsolete TPC7.5AHM3/86A. Both components share identical electrical specifications, automotive qualification, and physical packaging. The primary distinction is product status: the substitute is actively manufactured and supported by Vishay General Semiconductor - Diodes Division, while the original part is obsolete.

For new designs or ongoing production requiring TVS protection at 6.4V standoff with 133A peak pulse capability, the TPC7.5AHM3_A/H provides full functional compatibility. Both parts maintain AEC-Q101 automotive qualification and ROHS3 compliance, ensuring regulatory and quality standards are preserved across substitution.

The packaging difference (Tape & Reel for the substitute versus bulk for the original) reflects standard manufacturing practices for active products and does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can TPC7.5AHM3_A/H be used as a direct replacement for TPC7.5AHM3/86A?

A: Yes. Both components are electrically and mechanically identical across all critical parameters: voltage ratings (6.4V standoff, 7.13V breakdown, 11.3V clamping), current capacity (133A peak pulse), power dissipation (1500W), operating temperature range (-65°C to 185°C), package type (TO-277A SMPC), and automotive qualifications (AEC-Q101). The substitute is the active production equivalent.

Q: What is the difference between the two part numbers?

A: The TPC7.5AHM3/86A is obsolete, while TPC7.5AHM3_A/H is the active equivalent currently manufactured by Vishay. The suffix change reflects manufacturing revision and packaging format (Tape & Reel for active production). Electrical performance is identical.

Q: Are there any package or mounting differences?

A: Both parts use the same TO-277A (SMPC) surface mount package with identical pinout and footprint. The packaging format differs (bulk versus Tape & Reel), but this does not affect PCB assembly or electrical performance.

Q: Does the substitute maintain automotive and compliance certifications?

A: Yes. The TPC7.5AHM3_A/H retains all certifications of the original: Automotive grade, AEC-Q101 qualification, ROHS3 compliance, and unlimited moisture sensitivity level (MSL 1).

Q: Is the operating temperature range the same?

A: Yes. Both components operate across -65°C to 185°C junction temperature, maintaining performance across the full automotive temperature spectrum.
