Product details
Overview
SM6T10AHE3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features 10 V standoff voltage (VWM), 14.5 V max clamping voltage at 41 A peak pulse current (10/1000 μs), 600 W peak pulse power, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SM6T10AHE3_A/H datasheet, SM6T10AHE3_A/H pinout, SM6T10AHE3_A/H application, or SM6T10AHE3_A/H equivalent, key selection factors include its 10 V stand-off rating, low clamping ratio (1.45×VWM), RoHS-compliant matte tin terminals, MSL Level 1 rating, and suitability for automotive-grade ESD/surge protection in constrained PCB layouts.
Technical Context
The SM6T10AHE3_A/H operates as a unidirectional avalanche diode with cathode-banded polarity, leveraging glass-passivated junction technology for stable breakdown behavior under repetitive surge stress. Its clamping action begins at 9.5 V (min VBR) and fully limits transients to ≤14.5 V up to 41 A (10/1000 μs), enabling robust protection of downstream ICs and MOSFETs.
Thermally, it exhibits RθJA = 100 °C/W and RθJL = 20 °C/W, supporting operation from –65 °C to +150 °C junction temperature. The device is rated for 100 A non-repetitive forward surge (10 ms half-sine) and maintains <10 μA reverse leakage at 8.55 V (VWM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin. |
| VBR (min/max) | 9.50 V / 10.5 V - Breakdown occurs within this range at 1.0 mA test current; ensures predictable turn-on threshold. |
| VC @ IPPM | 14.5 V at 41.0 A (10/1000 μs) - Peak clamped voltage during worst-case surge; determines protected circuit's overvoltage exposure. |
| PPPM | 600 W - Peak pulse power handling capability; enables suppression of high-energy transients like ISO 7637-2 Pulse 1/2a. |
| TJ max. | +150 °C - Maximum junction temperature; supports under-hood automotive deployment without derating at 50 °C ambient. |
| Package | SMB (DO-214AA) - 3.94 mm × 2.20 mm footprint with 2.18 mm min cathode pad width; compatible with standard SMT reflow profiles (260 °C peak). |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional configuration with cathode band marking. Dimensions: 3.94 mm × 2.20 mm × 1.52 mm (L × W × H); terminals are matte tin-plated, solderable per J-STD-002/JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference node | Connected to lower-potential side (e.g., GND or return path); defines polarity-sensitive placement. |
| Cathode (banded end) | Avalanche conduction terminal / Clamping output node | Connected to protected line (e.g., 12 V rail or sensor input); conducts surge current to anode when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces per stress test requirements. |
| 600 W peak pulse power (10/1000 μs) | Withstands ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 2a (load dump initiation) without degradation. |
| Low clamping voltage (14.5 V @ 41 A) | Provides tighter overvoltage margin than generic 12 V system TVS devices, reducing risk of downstream IC latch-up. |
| MSL Level 1, 260 °C peak reflow | Eliminates moisture sensitivity concerns and pre-bake requirements during standard SMT assembly. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same VWM (8.55 V) and VC (14.5 V), but 400 W PPPM (vs. 600 W); SMB package identical. | Limited to lower-energy transients (e.g., IEC 61000-4-5 2nd edition); not recommended for ISO 7637-2 Pulse 5a. | Select SMAJ10A only if system-level surge testing does not exceed 400 W pulse energy and cost optimization is critical. |
| 1.5SMC10A | Higher package thermal resistance (RθJA ≈ 125 °C/W vs. 100 °C/W); same electrical specs but larger SMC (DO-214AB) footprint. | Requires PCB layout change (5.3 mm × 2.8 mm vs. 3.94 mm × 2.20 mm); better for high-temperature ambient (>85 °C) due to higher PD (5.0 W same). | Choose 1.5SMC10A when board space allows and thermal derating above 85 °C ambient is required. |
Compared with SMAJ10A and 1.5SMC10A, SM6T10AHE3_A/H delivers superior 600 W surge capacity in the smallest SMB footprint while maintaining AEC-Q101 qualification-making it optimal for space-constrained automotive and industrial designs requiring full ISO 7637-2 compliance.

The SM6T10AHE3_A/H has a maximum clamping voltage (VC) of 14.5 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 41.0 A. This value is measured per Figure 1 in the Vishay datasheet 88385 and defines the upper voltage limit imposed on protected circuitry during standardized surge events such as ISO 7637-2 Pulse 1.
Is SM6T10AHE3_A/H qualified for automotive applications?
Yes, SM6T10AHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code and explicit note in the Vishay SM6T datasheet (Rev. 09-Jan-2024). This qualification covers stress tests including HTGB, AC/DC life test, and temperature cycling-validating its use in engine control units, body electronics, and ADAS sensor modules.
What does the "HE3" suffix indicate in SM6T10AHE3_A/H?
The "HE3" suffix in SM6T10AHE3_A/H denotes RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering information table, "Base P/NHE3_X" indicates automotive-grade parts meeting both environmental and reliability standards, where "_A/H" specifies revision A and tape-and-reel packaging in 7″ reels (code H).

Yes, SM6T10AHE3_A/H is functionally and mechanically identical to SM6T10A-E3/52, sharing the same electrical characteristics, SMB (DO-214AA) package dimensions, and solderability. The "HE3" variant adds AEC-Q101 qualification, making it a drop-in upgrade for automotive designs without requiring PCB or firmware changes.
What is the thermal resistance from junction to ambient for SM6T10AHE3_A/H?
The typical thermal resistance from junction to ambient (RθJA) for SM6T10AHE3_A/H is 100 °C/W, measured on a 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pad per terminal, per Vishay datasheet 88385.
