TPSMP8.2HM3/84A Equivalent & Substitute Parts

Part Overview

The TPSMP8.2HM3/84A is a unidirectional Zener-type transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. Designed for surface mount applications in the DO-220AA (SMP) package, this component provides transient overvoltage protection with a 12.5V clamping voltage and 24A peak pulse current capability. The part is qualified to AEC-Q101 automotive standards and operates across the temperature range of -65°C to 185°C.

The TPSMP8.2HM3/84A has reached obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications requiring this specific protection characteristic.

Substitute Part Grouping Explanation

Substitution of the TPSMP8.2HM3/84A is determined by the following critical parameters:

  • Package compatibility: DO-220AA (SMP) surface mount package required
  • Voltage rating alignment: Reverse standoff voltage, breakdown voltage, and clamping voltage must fall within acceptable tolerance ranges for the protected circuit
  • Current handling: Peak pulse current rating must meet or exceed application requirements
  • Thermal performance: Operating temperature range must support the intended environment
  • Automotive qualification: AEC-Q101 certification required for automotive-grade applications
  • Compliance standards: RoHS3 compliance and REACH status must match or exceed the original part

The TPSMP8.2AHM3_A/H qualifies as a direct substitute based on these parameters while offering improved electrical performance characteristics.

Engineering Selection Recommendations

The TPSMP8.2AHM3_A/H is the qualified substitute for the obsolete TPSMP8.2HM3/84A. Both parts share identical package geometry (DO-220AA SMP), thermal operating range (-65°C to 185°C), automotive grade classification, and AEC-Q101 qualification status. Both maintain ROHS3 compliance and REACH unaffected status.

The substitute part demonstrates improved electrical performance: higher peak pulse current (24.8A vs. 24A), increased peak pulse power dissipation (400W vs. 300W), and lower clamping voltage (12.1V vs. 12.5V). These characteristics provide enhanced protection margins within the same physical footprint and thermal envelope.

The TPSMP8.2AHM3_A/H is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the TPSMP8.2AHM3_A/H be used as a direct replacement for the TPSMP8.2HM3/84A?

A: Yes. Both parts are housed in the DO-220AA (SMP) package with identical footprints and mounting requirements. Electrical parameters fall within compatible ranges for transient voltage suppression applications. Both carry AEC-Q101 automotive qualification and ROHS3 compliance.

Q: What are the key differences between these two parts?

A: The substitute part offers higher peak pulse current (24.8A vs. 24A), greater peak pulse power handling (400W vs. 300W), and a slightly lower clamping voltage (12.1V vs. 12.5V). The original part is obsolete; the substitute is in active production.

Q: Are there any package or mounting differences?

A: No. Both parts use the DO-220AA (SMP) surface mount package. PCB footprints, solder pad layouts, and mounting procedures are identical.

Q: Does the substitute part meet automotive qualification requirements?

A: Yes. The TPSMP8.2AHM3_A/H carries AEC-Q101 qualification and automotive grade classification, matching the original part's certification status.

Q: What is the packaging format for the substitute part?

A: The TPSMP8.2AHM3_A/H is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
