Product details
Overview
SMCG10A-M3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMCG (DO-215AB) package, with 11.1 V minimum breakdown voltage (VBR), 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 5.0 A peak pulse current, and 1500 W peak pulse power rating. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive and industrial control systems.
For engineers reviewing the SMCG10A-M3/9AT datasheet, SMCG10A-M3/9AT pinout, SMCG10A-M3/9AT application, or SMCG10A-M3/9AT equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, halogen-free RoHS compliance, thermal resistance data, and real-world protection use cases - all aligned to Vishay Document #88457 (Rev. 09-Jan-2024).
Technical Context
This TVS diode operates as a unidirectional clamping device with glass-passivated junction and low incremental surge resistance. Its 10/1000 µs waveform response supports transient suppression up to 1500 W, while its 75 °C/W junction-to-ambient thermal resistance requires defined copper pad layout (8.0 mm × 8.0 mm per terminal) for rated power dissipation.
The SMCG10A-M3/9AT features a cathode-band polarity marking, meets MSL Level 1 per J-STD-020, and is qualified to AEC-Q101 for automotive underhood applications. Its 1.0 µA max reverse leakage at VWM ensures minimal standby power loss in always-on circuits.
Key Specifications

|---|---|
| VBR (min) | 11.1 V - Ensures reliable conduction onset above normal 10 V system operating voltage |
| VWM | 10 V - Maximum continuous reverse voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 17.0 V - Clamped voltage during 5.0 A 10/1000 µs surge, limiting downstream stress |
| PPPM | 1500 W - Peak transient energy absorption capability under standardized surge waveform |
| RθJA | 75 °C/W - Requires 8.0 mm × 8.0 mm copper pads per terminal to sustain 6.5 W power dissipation |

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-E3/57T | Same VWM (10 V) and VC (17.0 V), but lower PPPM (400 W) and SMA (DO-214AC) package | Limited to lower-energy transients; unsuitable for automotive load-dump events | Select when board space is constrained and surge energy remains below 400 W |
| SMCJ10A-M3/9AT | Identical VWM, VBR, and VC, but higher PPPM (1500 W) in larger SMC (DO-214AB) package with RθJA = 35 °C/W | Better thermal performance enables sustained surge duty cycles in high-power industrial drives | Choose for designs requiring >1500 W single-pulse handling or improved thermal margin |
Compared with SMAJ10A-E3/57T, SMCG10A-M3/9AT delivers 275% higher surge power capacity in a smaller footprint; versus SMCJ10A-M3/9AT, it trades thermal efficiency for space savings - critical in dense automotive ECUs where DO-215AB's 30% smaller area reduces PCB layer count.

FAQ
What is the clamping voltage of the SMCG10A-M3/9AT under a 5.0 A transient?
The SMCG10A-M3/9AT has a maximum clamping voltage (VC) of 17.0 V when subjected to a 5.0 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCG10A-M3/9AT maintains this clamping performance across its qualified operating temperature range of -55 °C to +150 °C.
Is the SMCG10A-M3/9AT suitable for automotive applications?
Yes, the SMCG10A-M3/9AT is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its halogen-free M3 construction, MSL Level 1 rating, and validated performance under temperature cycling and high-temperature reverse bias confirm suitability for under-hood environments. The SMCG10A-M3/9AT meets automotive load-dump and ISO 7637-2 test requirements when applied with proper PCB layout.
What does the "M3" suffix mean in SMCG10A-M3/9AT?
The "M3" suffix in SMCG10A-M3/9AT indicates halogen-free, RoHS-compliant construction with industrial-grade reliability and JESD201 Class 2 whisker resistance. It distinguishes the part from E3 (standard RoHS) and HM3 (AEC-Q101 + halogen-free) variants. The SMCG10A-M3/9AT retains full electrical specifications and AEC-Q101 qualification while meeting stringent environmental mandates for modern automotive and industrial manufacturing.
How does the SMCG10A-M3/9AT compare to bidirectional versions like SMCG10CA?
The SMCG10A-M3/9AT is unidirectional and features a cathode band for polarity identification, whereas SMCG10CA is bidirectional with no polarity marking and symmetric breakdown in both directions. The SMCG10A-M3/9AT offers lower leakage (<1.0 µA at 10 V) and is preferred for DC rail protection; SMCG10CA suits AC-coupled or floating signal lines. Both share identical VBR, VC, and PPPM, but the SMCG10A-M3/9AT must be oriented correctly during placement.
What PCB layout guidance applies to the SMCG10A-M3/9AT for thermal performance?
Vishay specifies that the SMCG10A-M3/9AT must be mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve its rated 6.5 W power dissipation and 75 °C/W RθJA. Reduced pad area increases thermal resistance and requires derating per Figure 2 in Document #88457. The SMCG10A-M3/9AT's DO-215AB gull-wing leads require standard SMT reflow profiles with peak temperature ≤260 °C (MSL Level 1).
