Product details
Overview
SMCG10A-E3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMCG (DO-215AB) package, with a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V clamping voltage (VC) at 88.2 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) rating for 10/1000 µs transients. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCG10A-E3/9AT datasheet, SMCG10A-E3/9AT pinout, SMCG10A-E3/9AT application, or SMCG10A-E3/9AT equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 1500 W surge capability, DO-215AB thermal performance (RθJA = 75 °C/W), and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuit nodes, responding to fast transient overvoltages (e.g., inductive switching spikes or ESD events) by entering avalanche conduction below its maximum clamping voltage of 17.0 V. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (≤5.0 µA at VWM).
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it delivers 1500 W peak pulse power handling with derating above 25 °C per Fig. 2, and supports surge currents up to 200 A (IFSM, 8.3 ms half-sine) in unidirectional configurations only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 11.1 V / 12.3 V at 1 mA - Ensures reliable turn-on within tight tolerance for predictable protection threshold |
| VC @ IPPM | 17.0 V at 88.2 A - Limits downstream voltage stress during 10/1000 µs surges to safe levels |
| PPPM | 1500 W - Sustains high-energy transients without failure under standard waveform conditions |
| TJ max | +150 °C - Enables operation in under-hood automotive and high-ambient industrial environments |
| RθJA | 75 °C/W - Requires minimum 8.0 mm × 8.0 mm copper pad area per terminal for thermal management |

Applications
| Automotive Power Distribution | Industrial Sensor Signal Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp surges before they reach DC-DC converters or microcontrollers. Use Value: Clamps 10/1000 µs transients to ≤17.0 V while dissipating 1500 W, preventing latch-up or gate oxide damage in downstream silicon. | Use Scenario: Shielding analog output lines of pressure or temperature sensors from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS connected across signal and ground to suppress sub-100 ns ESD pulses without distorting millivolt-level signals. Use Value: Sub-5 µA leakage at 10 V ensures minimal offset error; fast response preserves signal integrity in 100 kSPS+ data acquisition systems. |
| Consumer Power Adapter Input Stage | Telecom Line Interface Protection |
Use Scenario: Safeguarding AC-DC adapter primary-side controllers from lightning-induced surges on mains input. IC Role / Device Role / Timing Role: Primary-side TVS shunting transient energy to earth ground before rectification and regulation stages. Use Value: Withstands 200 A non-repetitive forward surge (IFSM), enabling robustness against repeated line-switching events in global plug-in devices. | Use Scenario: Protecting Ethernet PHY interface pins from induced surges on PoE or data lines in outdoor base stations. IC Role / Device Role / Timing Role: Bidirectional-capable family variant used in unidirectional configuration to guard isolated DC bias rails feeding RF front-end modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same VWM (10 V) and VC (17.0 V), but lower PPPM (400 W) and smaller SMA package (DO-214AC) | Limited to lower-energy transients; unsuitable for automotive load dump or industrial motor drive noise | Select SMAJ10A only for cost-sensitive consumer applications with <500 W surge exposure |
| SMCJ10A | Identical VWM (10 V), VC (17.0 V), and PPPM (1500 W), but larger SMC package (DO-214AB) with higher RθJA (60 °C/W) | Requires larger PCB area; better suited for high-volume automated assembly where thermal relief is less constrained | Choose SMCJ10A when board space allows and legacy SMC footprint compatibility is required |
Compared with SMCG10A-E3/9AT, SMAJ10A offers reduced surge capacity in a smaller footprint, while SMCJ10A matches power rating but trades compactness for easier thermal management-making SMCG10A-E3/9AT optimal for space-constrained AEC-Q101 designs needing both miniaturization and full 1500 W compliance.

FAQ
What is the clamping voltage of SMCG10A-E3/9AT under a 10/1000 µs surge?
The SMCG10A-E3/9AT has a maximum clamping voltage (VC) of 17.0 V at 88.2 A peak pulse current (IPPM) for a 10/1000 µs waveform. This value is measured under standardized test conditions with the device mounted on 8.0 mm × 8.0 mm copper pads per JEDEC guidelines, ensuring repeatable protection performance in production layouts.
Is SMCG10A-E3/9AT qualified for automotive applications?
Yes, SMCG10A-E3/9AT is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per the AEC-Q101 standard. The "E3" suffix denotes RoHS-compliant industrial grade, and the full qualification applies to the SMCG10A base device regardless of reel packaging (e.g., /9AT).
What does the "/9AT" suffix indicate in SMCG10A-E3/9AT?
The "/9AT" suffix specifies the packaging format: 13-inch diameter plastic tape and reel containing 3500 units. This differs from "/57T", which denotes 7-inch reels with 850 units. Both share identical electrical and mechanical specifications-the suffix affects only logistics and assembly line feed configuration.
Can SMCG10A-E3/9AT be used in bidirectional circuits?
No-SMCG10A-E3/9AT is unidirectional, as confirmed by its part number ending in "A" (not "CA") and cathode band marking. For bidirectional operation, Vishay specifies variants like SMCG10CA, which exhibit symmetrical breakdown in both directions and lack polarity marking.
What is the thermal resistance of SMCG10A-E3/9AT, and how does it affect layout?
The SMCG10A-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pad per terminal. To maintain safe junction temperatures under 1500 W surge loads, PCB layout must adhere to this pad size; reducing pad area increases thermal impedance and risks thermal runaway during repetitive events.
