Product details
Overview
TA6F10AHM3/6A from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching transients and ESD events on signal lines. It features a 9.5–10.5 V breakdown voltage (VBR), 8.55 V maximum standoff voltage (VWM), 14.5 V clamping voltage at 41.4 A peak pulse current, 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TA6F10AHM3/6A datasheet, TA6F10AHM3/6A pinout, TA6F10AHM3/6A application, or TA6F10AHM3/6A equivalent, this device is selected for high-temperature (TJ = 185 °C), low-profile (0.95 mm height), automated-placement-ready protection of MOSFET gates, sensor I/O, and microcontroller signal lines in harsh environments.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge stress and elevated junction temperatures up to 185 °C. Its DO-221AC (SlimSMA) package enables high-density PCB layouts while maintaining robust thermal resistance (RθJA = 145 °C/W) and low parasitic capacitance.
The device operates unidirectionally with 5.0 μA max reverse leakage at VWM, supports IEC 61000-4-2 Level 4 ESD immunity (±15 kV air / ±8 kV contact), and meets J-STD-020 MSL Level 1 with 260 °C reflow peak temperature tolerance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same DO-214AC package but higher RθJA (160 °C/W), lower TJ max (150 °C), non-AEC-Q101 | Limited to commercial/industrial use; not qualified for automotive under-hood deployment | Select SMAJ10A only if AEC-Q101 is not required and ambient temperature remains below 85 °C |
| SMCJ10A | DO-214AB package (higher profile: 2.3 mm), 1500 W PPPM, same VBR/VC range, AEC-Q101 qualified | Requires more PCB area and cannot fit in ultra-thin assemblies; suited for higher-energy surge environments | Choose SMCJ10A where surge energy exceeds 600 W but space constraints allow larger footprint |
Compared with SMAJ10A and SMCJ10A, TA6F10AHM3/6A uniquely combines AEC-Q101 qualification, 0.95 mm height, and 185 °C operation-making it optimal for space-constrained automotive modules where thermal headroom and reliability are critical.

FAQ
What is the maximum clamping voltage of the TA6F10AHM3/6A during a 10/1000 μs surge?
The TA6F10AHM3/6A has a maximum clamping voltage (VC) of 14.5 V at its rated peak pulse current of 41.4 A (10/1000 μs waveform). This value is measured per the conditions specified in the Vishay datasheet Document Number 89939 and ensures downstream circuitry remains within safe voltage limits during standardized surge events. The TA6F10AHM3/6A maintains this clamping performance across its full operating temperature range.
Is the TA6F10AHM3/6A suitable for automotive under-hood applications?
Yes, the TA6F10AHM3/6A is AEC-Q101 qualified and rated for a maximum junction temperature of 185 °C, making it suitable for under-hood automotive applications such as engine control units, transmission modules, and ADAS sensor interfaces. Its DO-221AC package and thermal resistance characteristics support reliable operation without additional heatsinking in typical mounting configurations. The TA6F10AHM3/6A meets the environmental stress requirements defined in the AEC-Q101 standard.
What does the "HM3/6A" suffix indicate in TA6F10AHM3/6A?
The "HM3" suffix denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads compliant with J-STD-002 and JESD22-B102. The "/6A" indicates packaging in 7-inch diameter plastic tape and reel with a base quantity of 3500 units. This ordering code ensures traceability, compatibility with high-speed pick-and-place equipment, and adherence to automotive manufacturing standards. The TA6F10AHM3/6A is fully specified under this exact part number in Vishay's official documentation.
How does the TA6F10AHM3/6A compare to standard SMAJ-series TVS diodes?
The TA6F10AHM3/6A offers superior thermal capability (185 °C vs. 150 °C), lower profile (0.95 mm vs. 2.3 mm), and AEC-Q101 qualification compared to SMAJ10A. Its DO-221AC package reduces board space by ~40% while maintaining equivalent electrical parameters. Unlike SMAJ10A, the TA6F10AHM3/6A is validated for automotive under-hood use and exhibits improved long-term stability under thermal cycling. The TA6F10AHM3/6A delivers these advantages without compromising clamping performance or surge handling.
What is the reverse leakage current specification for TA6F10AHM3/6A at its maximum operating temperature?
At VWM = 8.55 V and TJ = 150 °C, the TA6F10AHM3/6A exhibits a maximum reverse leakage current (IR) of 1000 μA, per the Vishay datasheet Table on page 2. At room temperature (25 °C), leakage is limited to 5.0 μA. This controlled leakage ensures minimal power loss in always-on circuits while preserving signal integrity in high-impedance sensor interfaces. The TA6F10AHM3/6A maintains these values across its full qualified temperature range.
