Product details
Overview
TPC8.2HM3/86A 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 TPC8.2HM3/86A datasheet, TPC8.2HM3/86A pinout, TPC8.2HM3/86A application, or TPC8.2HM3/86A 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 signal lines.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive transients. Its unidirectional configuration supports DC-biased protection paths with defined anode-cathode polarity and no reverse conduction during normal operation.
The device meets J-STD-020 MSL Level 1, withstands 200 A 8.3 ms surge current, and delivers 1500 W peak pulse power per 10/1000 μs waveform. Its thermal design enables sustained operation at TJ = 185 °C, supporting under-hood automotive environments and high-power industrial controls.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 13.5 V.

IC Role / Device Role / Timing Role: Low-capacitance TVS on differential or single-ended signal lines exposed to ESD and switching noise. Use Value: Sub-1 ns response time and 200 μA leakage preserve signal integrity while meeting IEC 61000-4-2 Level 4. |
| Consumer Power Adapter Input Stage | Telecom DC Power Distribution |
Use Scenario: Input-side surge suppression in AC/DC adapters for smart home gateways and IoT hubs. IC Role / Device Role / Timing Role: Primary-line TVS after bridge rectifier, before bulk capacitor and primary-side controller. Use Value: 1500 W peak power rating handles repeated 1 kV/500 A surges per IEC 61000-4-5, reducing need for redundant stages. | Use Scenario: Secondary-side DC bus protection in 48 V telecom power shelves and ONU equipment. IC Role / Device Role / Timing Role: Parallel-mounted TVS on +48 V distribution rails feeding multiple board-level converters. Use Value: Dual-cathode configuration lowers effective clamping impedance, improving system-level surge margin by ≥15 % vs. single-cathode devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS 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 AEC-Q101 qualified; limited to commercial-temperature industrial use | Choose for cost-sensitive non-automotive designs where surge energy is <100 mJ |
| TPC8.2HM3/86A | 1500 W PPPM, TO-277A package (lower RθJA), VC = 12.1 V @ 200 A, AEC-Q101 qualified | Required for automotive front-end protection and high-energy industrial transients | Preferred when full ISO 7637-2 compliance and 185 °C operation are mandatory |
Compared with SMAJ8.0A and P6SMB8.0A, TPC8.2HM3/86A provides 3.7× higher peak power, dual-cathode low-impedance clamping, and automotive-grade qualification-making it suitable for mission-critical 12 V rail protection where thermal margin and reliability are non-negotiable.

FAQ
What is the exact breakdown voltage range for TPC8.2HM3/86A at 10 mA test current?
The TPC8.2HM3/86A has a guaranteed breakdown voltage range of 7.79 V (minimum) to 8.61 V (maximum) at 10 mA test current, with a nominal value of 8.20 V. This specification is measured per ANSI/IEEE C62.35 and confirmed in Vishay's official datasheet revision 19-Apr-2022 (Document Number: 89056). The tight tolerance supports precise overvoltage threshold setting in safety-critical circuits.
Is TPC8.2HM3/86A suitable for automotive applications requiring AEC-Q101 qualification?
Yes, TPC8.2HM3/86A is explicitly AEC-Q101 qualified and rated for TJ = -65 °C to +185 °C operation. It meets all required stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. This makes TPC8.2HM3/86A appropriate for under-hood and transmission-control module applications where automotive-grade reliability is mandatory.
What does the "HM3/86A" suffix indicate in TPC8.2HM3/86A?
The "HM3" denotes Vishay's halogen-free, RoHS-compliant, AEC-Q101 qualified base package code for the SMPC (TO-277A) outline. The "86A" is the revision code indicating the specific process and qualification batch-consistent with Vishay's internal tracking for material composition, plating, and reliability validation. This suffix confirms full compliance with JESD201 Class 2 whisker resistance and UL 94 V-0 molding compound.
How does the dual-cathode configuration of TPC8.2HM3/86A improve surge performance?
The dual-cathode structure (Pins 1 and 2) in TPC8.2HM3/86A reduces total effective clamping impedance during high-current transients by distributing surge current across two parallel paths. This yields lower dynamic voltage overshoot and improved thermal sharing-verified by 200 A IPPM clamping at only 12.1 V, compared to 12.5 V or higher in single-cathode equivalents of similar power rating.
Can TPC8.2HM3/86A be used in place of TPC8.2A in existing designs?
Yes-TPC8.2HM3/86A is a direct replacement for TPC8.2A with identical electrical specifications, pinout, and package dimensions. The HM3/86A variant adds halogen-free construction, enhanced whisker resistance (JESD201 Class 2), and updated AEC-Q101 requalification. No PCB layout or schematic changes are required when upgrading from TPC8.2A to TPC8.2HM3/86A.
