Product details
Overview
TPC8.2AHM3/86A from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, designed for high-reliability automotive and industrial electronics protection. It features a breakdown voltage of 7.79–8.61 V at 10 mA, clamping voltage of 12.1 V at 200 A peak pulse current, and operates up to 185 °C junction temperature.
For engineers reviewing the TPC8.2AHM3/86A datasheet, TPC8.2AHM3/86A pinout, TPC8.2AHM3/86A application, or TPC8.2AHM3/86A equivalent, key selection criteria include unidirectional surge clamping performance, AEC-Q101 qualification, low-profile 1.1 mm height, and compatibility with automated SMT placement on power rails and sensor signal lines.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional architecture enables robust forward conduction during overvoltage events while maintaining tight leakage control (≤200 μA at 7.02 V).
The device is rated for 10/1000 μs waveform peak pulse power of 1500 W and supports 8.3 ms half-sine surge currents up to 200 A. Thermal design is enabled by its 185 °C maximum junction temperature and compliance with MSL Level 1 per J-STD-020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | Lower PPPM (400 W), SMA package (higher thermal resistance), VC = 12.5 V @ 32.4 A | Not rated for automotive use; lacks AEC-Q101 qualification and 185 °C rating | Use only in cost-sensitive consumer applications with lower surge exposure |
| TPC8.2AHE3/86A | Same electrical specs; differs only in tape-and-reel packaging (7″ vs. 13″ reel, different base quantity) | No functional difference; identical performance and qualification | Select based on production volume and SMT line feeder compatibility |

FAQ
What is the clamping voltage of the TPC8.2AHM3/86A at its rated peak pulse current?
The TPC8.2AHM3/86A has a maximum clamping voltage (VC) of 12.1 V when subjected to its rated peak pulse current (IPPM) of 200 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 89056 and ensures downstream components remain within safe voltage limits during surge events. The TPC8.2AHM3/86A achieves this with low incremental surge resistance and fast response time.
Is the TPC8.2AHM3/86A qualified for automotive applications?
Yes, the TPC8.2AHM3/86A is AEC-Q101 qualified and rated for operation up to 185 °C junction temperature, making it suitable for under-hood and powertrain applications. It meets MSL Level 1 per J-STD-020 and is halogen-free, RoHS-compliant. The TPC8.2AHM3/86A is explicitly listed in Vishay's automotive-grade TVS portfolio for use in ECUs, body control modules, and ADAS power supplies.
What does the 'HM3/86A' suffix indicate in TPC8.2AHM3/86A?
The 'HM3' denotes the halogen-free, RoHS-compliant, AEC-Q101-qualified SMPC (TO-277A) package with matte tin-plated leads; '86A' is the revision code indicating the specific process and test lot version per Vishay's internal tracking. The full TPC8.2AHM3/86A part number maps to the DKP-marked device in the TPC6.8A–TPC51A family and confirms compliance with JESD201 Class 2 whisker testing.
Can the TPC8.2AHM3/86A be used in bidirectional configurations?
No, the TPC8.2AHM3/86A is strictly unidirectional and must be connected with cathode toward the protected line and anode to ground. Bidirectional protection requires two devices in series opposition or a dedicated bidirectional TVS such as the SMBJ8.0CA. Using the TPC8.2AHM3/86A in reverse polarity risks permanent failure, as confirmed in the "Unidirection only" feature statement in Vishay document 89056.
What is the maximum leakage current of the TPC8.2AHM3/86A at its standoff voltage?
The TPC8.2AHM3/86A exhibits a maximum reverse leakage current (IR) of 200 μA at its standoff voltage (VWM) of 7.02 V and ambient temperature of 25 °C. At elevated temperature (TJ = 150 °C), leakage increases to 2000 μA - a value specified in the Electrical Characteristics table of Vishay document 89056 and critical for low-power always-on circuits where quiescent current must be tightly controlled.
