Product details
Overview
SM6T10AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 10 V breakdown voltage (VBR = 9.5–10.5 V at IT = 1.0 mA), 8.55 V stand-off voltage (VWM), 14.5 V clamping voltage (VC) at 41.0 A peak pulse current, and 600 W peak pulse power rating per 10/1000 μs waveform. It protects MOSFETs and ICs against inductive switching transients in automotive power modules.
For engineers reviewing the SM6T10AHE3_A/I datasheet, SM6T10AHE3_A/I pinout, SM6T10AHE3_A/I application, or SM6T10AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low-inductance SMB package, and compliance with J-STD-020 MSL level 1 reflow profile.
Technical Context
The SM6T10AHE3_A/I operates as a clamping-type transient suppressor using an avalanche breakdown mechanism. Its glass-passivated silicon junction delivers stable reverse standoff (8.55 V) and precise breakdown (9.5–10.5 V) with ≤1000 μA leakage at VWM, enabling reliable overvoltage protection in DC-biased signal and power rails.
Designed for automotive-grade reliability, it meets AEC-Q101 stress test requirements and supports solder reflow up to 260 °C peak (MSL level 1). Thermal resistance is 100 °C/W junction-to-ambient (on 5.0 mm × 5.0 mm copper pads), limiting steady-state dissipation to 5.0 W at TA = 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.50 V / 10.5 V at 1.0 mA - defines precise avalanche initiation threshold for repeatable clamping behavior |
| VWM | 8.55 V - maximum continuous reverse voltage before significant leakage; sets safe operating margin below VBR |
| VC @ IPPM | 14.5 V at 41.0 A (10/1000 μs) - clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - peak transient energy absorption capability under standardized 10/1000 μs waveform |
| IFSM | 100 A - single half-sine surge current rating (10 ms), critical for load-dump immunity in 12 V automotive systems |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood environments |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 2.20 mm height and 5.59 mm length for automated placement |
Pinout & Package
SMB (DO-214AA) package: molded plastic case with matte tin-plated leads, UL 94 V-0 rated compound, cathode band marking on unidirectional devices. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H).

| Cathode | Avalanche clamping terminal | Marked with band; connected to higher-potential side; initiates controlled breakdown when VRM exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics requiring zero-failure field performance |
| Low-inductance SMB layout | Minimizes voltage overshoot during fast transients (e.g., ISO 7637-2 pulse 1/2a/5a), improving clamping response |
| MSL level 1 moisture sensitivity | Enables standard SMT reflow without baking; compatible with high-volume manufacturing at 260 °C peak |
| 600 W peak pulse power | Handles automotive load-dump surges (ISO 16750-2) and inductive switch-off spikes without degradation |

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 SMB package, but lower PPPM = 400 W; VC = 16.0 V at 25.0 A | Not AEC-Q101 qualified; limited to commercial-grade industrial use | Select SMAJ10A only if surge energy is ≤400 W and automotive qualification is not required |
| 1.5SMC10A | Larger SMC (DO-214AB) package; same VBR/VC specs but higher IPPM = 49.0 A and PPPM = 1500 W | Higher thermal mass enables longer surge duration handling; less suitable for space-constrained PCBs | Choose 1.5SMC10A when system-level testing requires >600 W surge margin or extended pulse width immunity |
Compared with SMAJ10A and 1.5SMC10A, SM6T10AHE3_A/I uniquely balances AEC-Q101 qualification, 600 W pulse rating, and compact SMB footprint-making it optimal for automotive ECUs where board area, reliability, and standardized surge compliance are jointly constrained.

FAQ
What is the exact breakdown voltage range specified for SM6T10AHE3_A/I?
The SM6T10AHE3_A/I has a guaranteed breakdown voltage (VBR) range of 9.50 V to 10.5 V at test current IT = 1.0 mA, as confirmed in the Vishay SM6T datasheet revision 09-Jan-2024, page 2. This tight 10% tolerance ensures predictable clamping onset in safety-critical automotive circuits where overvoltage margins must be precisely controlled.
Is SM6T10AHE3_A/I qualified for automotive applications?
Yes, SM6T10AHE3_A/I is AEC-Q101 qualified, as explicitly stated in the Vishay documentation under "MECHANICAL DATA" and "ORDERING INFORMATION" sections. The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction, making SM6T10AHE3_A/I suitable for engine control, body electronics, and ADAS modules requiring certified reliability.
What is the clamping voltage of SM6T10AHE3_A/I under standard surge conditions?
The SM6T10AHE3_A/I clamps to a maximum of 14.5 V at 41.0 A peak pulse current (IPPM) under the 10/1000 μs waveform, per the Electrical Characteristics table on page 2 of the Vishay SM6T datasheet. This value directly determines the maximum stress imposed on downstream components during transient events.
Does SM6T10AHE3_A/I have bidirectional capability?
No, SM6T10AHE3_A/I is a unidirectional TVS diode. Its part number lacks the "CA" suffix (e.g., SM6T10CA), and the Vishay datasheet specifies polarity as "unidirectional" for all "A"-suffixed variants. Bidirectional operation requires explicit "CA" designation and symmetric VBR characteristics in both directions.
What package type and dimensions does SM6T10AHE3_A/I use?
SM6T10AHE3_A/I uses the SMB (DO-214AA) package, with mechanical dimensions of 4.57 mm × 3.94 mm × 2.20 mm (length × width × height), as shown in the "PACKAGE OUTLINE DIMENSIONS" diagram on page 4 of the Vishay SM6T datasheet. The cathode is marked by a visible band on the body.
