Product details
Overview
SM6T10CAHM3/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 10 V standoff voltage (VWM), 12.8 V breakdown voltage (VBR min), and 600 W peak pulse power (10/1000 μs). It clamps transients to ≤18.6 V at 41 A IPPM and operates from −65 °C to +150 °C, used for protecting automotive sensor signal lines against inductive switching surges.
For engineers reviewing the SM6T10CAHM3/I datasheet, SM6T10CAHM3/I pinout, SM6T10CAHM3/I application, or SM6T10CAHM3/I equivalent, key selection criteria include bidirectional polarity, AEC-Q101 qualification, halogen-free RoHS compliance, low clamping voltage, and SMB footprint compatibility with automated SMT assembly.
Technical Context
This bidirectional TVS diode features symmetric clamping behavior in both forward and reverse directions, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM).
Designed for high-energy transient suppression, it delivers 600 W peak pulse power under standardized 10/1000 μs waveform conditions with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W, supporting reliable operation on minimum 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min) | 12.8 V - guaranteed breakdown voltage at 1.0 mA test current, defining turn-on threshold |
| VC (max) | 18.6 V - maximum clamping voltage at 41 A peak pulse current, limiting protected circuit stress |
| PPPM | 600 W - peak transient energy absorption capability under 10/1000 μs waveform |
| TJ max | +150 °C - maximum junction temperature enabling use in under-hood automotive environments |

Pinout & Package
Package: SMB (DO-214AA), halogen-free, RoHS-compliant, matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Bidirectional construction means no polarity marking; terminals are symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same SMB package, 600 W rating, but VWM = 10 V, VBR min = 11.1 V, VC max = 17.0 V at 35.3 A; not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated | Select SMAJ10CA for cost-sensitive non-automotive applications requiring lower clamping voltage |
| SMCJ10CA | Higher 1500 W PPPM rating in larger SMC (DO-214AB) package; VWM = 10 V, VBR min = 11.1 V, VC max = 17.0 V at 88.2 A | Requires larger PCB area and higher mounting pad thermal mass; suited for higher-energy surge environments | Choose SMCJ10CA when system-level surge testing exceeds 600 W requirements or when derating margin is critical |
Compared with SMAJ10CA and SMCJ10CA, SM6T10CAHM3/I uniquely combines AEC-Q101 qualification, halogen-free compliance, and SMB footprint-making it optimal for space-constrained automotive signal line protection where qualification and material compliance are mandatory.

FAQ
What does the "CA" suffix indicate in SM6T10CAHM3/I?
The "CA" suffix in SM6T10CAHM3/I denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities. Unlike unidirectional variants (e.g., SM6T10AHM3/I), SM6T10CAHM3/I has no cathode marking and functions identically regardless of voltage polarity across its terminals-ideal for AC signal lines or differential buses.
Is SM6T10CAHM3/I qualified for automotive applications?
Yes, SM6T10CAHM3/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3" and documentation revision 09-Jan-2024 (Document Number: 88385). This qualification covers stress tests including HTGB, HTRB, TCT, and mechanical shock, validating its suitability for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage of SM6T10CAHM3/I and at what current?
The maximum clamping voltage (VC) of SM6T10CAHM3/I is 18.6 V, measured at a peak pulse current (IPPM) of 41 A under the standard 10/1000 μs waveform. This value is specified in the Electrical Characteristics table on page 2 of the Vishay datasheet and defines the upper voltage limit imposed on protected circuits during surge events.
Does SM6T10CAHM3/I require special PCB layout considerations?
Yes, SM6T10CAHM3/I requires minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for thermal performance and pulse current handling, as specified in the "Mechanical Data" section. Use short, wide traces to minimize inductance, and avoid vias in series with the TVS path to preserve clamping speed and effectiveness.
How does the HM3 suffix differ from E3 or M3 in SM6T10CAHM3/I?
The HM3 suffix in SM6T10CAHM3/I indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification. In contrast, E3 is RoHS-compliant only (commercial grade), and M3 is halogen-free and RoHS-compliant but not AEC-Q101 qualified. The "I" denotes tape-and-reel packaging in 13" diameter reels (3200 units).
