Product details
Overview
SMCG8.0A-E3/9AT from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) diode in DO-215AB (SMCG) package, designed for clamping inductive switching transients and ESD events on power and signal lines. It features 8.0 V stand-off voltage (VWM), 6.40–9.83 V breakdown range (VBR), 13.6 V maximum clamping voltage (VC) at 110.3 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform - used in automotive sensor protection and industrial DC power rails.
For engineers reviewing the SMCG8.0A-E3/9AT datasheet, SMCG8.0A-E3/9AT pinout, SMCG8.0A-E3/9AT application, or SMCG8.0A-E3/9AT equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), polarity marking (cathode band), and reel packaging details (13" tape, 3500 pcs) to support circuit protection design, BOM validation, and automotive-grade sourcing decisions.
Technical Context
This TVS diode operates as a unidirectional clamping device with glass-passivated junction and low incremental surge resistance, enabling fast response (<1 ns) to transient overvoltages. Its 1500 W PPPM rating is specified under standardized 10/1000 µs waveform conditions with derating above TA = 25 °C per Fig. 2.
The SMCG8.0A-E3/9AT uses a DO-215AB package with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102, meets UL 94 V-0 flammability, and is qualified to AEC-Q101 - confirming suitability for automotive electronics where reliability under thermal cycling and mechanical stress is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - maximum continuous reverse operating voltage before clamping begins; sets threshold for protection of 5 V–12 V logic and power rails. |
| VBR min/max | 6.40 V / 9.83 V at IT = 10 mA - guaranteed breakdown window ensures consistent turn-on across production lots and temperature. |
| VC @ IPPM | 13.6 V at 110.3 A - clamping voltage defines worst-case overvoltage seen by protected IC during 10/1000 µs surge. |
| PPPM | 1500 W - peak transient energy handling capacity under standard waveform; determines survivability against IEC 61000-4-5 Level 4 surges. |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance on recommended 8.0 mm × 8.0 mm copper pads; informs thermal margin in compact PCB layouts. |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments without derating. |
| AEC-Q101 | Qualified - validated for automotive use including temperature cycling, humidity bias, and mechanical shock per AEC specification. |
Pinout & Package
Package: DO-215AB (SMCG) - surface-mount, low-profile gull-wing leaded case with cathode band marking on unidirectional variants. Molding compound meets UL 94 V-0; terminals are matte tin plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward conduction mode | Connected to lower-potential side (e.g., GND) in unidirectional clamp configuration; must be routed with low-inductance path for effective surge shunting. |
| Cathode | Current exit terminal; marked with band | Connected to protected line (e.g., 12 V rail); polarity marking ensures correct orientation during automated placement and prevents reverse-bias failure. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable VBR over lifetime and improved moisture resistance vs. epoxy-passivated alternatives - critical for automotive under-hood reliability. |
| Low incremental surge resistance | Minimizes VC rise under high di/dt transients, ensuring tighter clamping than standard Zener-based TVS devices at same PPPM rating. |
| MSL Level 1 (J-STD-020) | Allows unlimited floor life and reflow up to 260 °C peak - eliminates baking requirements and supports high-yield SMT assembly. |
| AEC-Q101 qualification | Validates robustness for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| RoHS-compliant (E3 suffix) | Meets industrial-grade environmental compliance without halogen-free requirement; compatible with standard Pb-free reflow profiles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A-E3/57T | Same VWM (8.0 V), but SMA package (DO-214AC); RθJA = 85 °C/W; lower PPPM (400 W); no AEC-Q101 qualification. | Targeted at cost-sensitive consumer electronics; not suitable for automotive or high-reliability industrial use. | Select when board space allows larger footprint and AEC-Q101 is not required; verify thermal margin with higher RθJA. |
| SMCJ8.0A-E3/9AT | Same DO-215AB package and AEC-Q101 qualification; higher PPPM (1500 W); identical VWM/VBR/VC specs; same reel size (3500 pcs). | Direct functional replacement with identical mounting and thermal behavior; differs only in JEDEC designation (SMCJ vs SMCG) and minor process optimization. | Preferred for new designs requiring full documentation traceability to latest Vishay revision; SMCG8.0A-E3/9AT remains valid for legacy BOMs. |
Compared with SMAJ8.0A-E3/57T, SMCG8.0A-E3/9AT delivers 275% higher surge power handling and automotive qualification; versus SMCJ8.0A-E3/9AT, it offers identical protection performance in the same footprint but reflects updated manufacturing process and test methodology per Revision 09-Jan-2024.

FAQ
What is the clamping voltage of SMCG8.0A-E3/9AT at its rated peak pulse current?
The SMCG8.0A-E3/9AT has a maximum clamping voltage (VC) of 13.6 V at 110.3 A peak pulse current (IPPM), measured under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuits during surge events and is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88457. The SMCG8.0A-E3/9AT maintains this clamping performance across its operational temperature range.
Is SMCG8.0A-E3/9AT qualified for automotive applications?
Yes, SMCG8.0A-E3/9AT is AEC-Q101 qualified, as explicitly stated in the Mechanical Data section and confirmed in the Notes on page 2 of Vishay document 88457. This qualification covers stress tests including temperature cycling, humidity bias, and mechanical shock - validating its use in engine control units, body electronics, and ADAS sensor modules. The SMCG8.0A-E3/9AT meets automotive-grade reliability requirements without derating.
What does the "E3/9AT" suffix indicate in SMCG8.0A-E3/9AT?
The "E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads; "9AT" specifies packaging in 13-inch diameter plastic tape and reel containing 3500 units. This matches the ordering information on page 3 of Vishay document 88457. The SMCG8.0A-E3/9AT is not halogen-free (that would require M3 suffix) nor AEC-Q101 enhanced (which would use HE3/HM3), but retains full AEC-Q101 qualification via base SMCG construction.
How does the thermal resistance of SMCG8.0A-E3/9AT affect PCB layout?
The SMCG8.0A-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal, as specified in the Thermal Characteristics table. To maintain safe junction temperatures under repeated surges, designers must implement minimum pad dimensions and consider thermal vias beneath the leads. This RθJA value directly impacts allowable power dissipation and duty cycle in high-frequency transient environments for the SMCG8.0A-E3/9AT.
Can SMCG8.0A-E3/9AT be used in bidirectional configurations?
No - SMCG8.0A-E3/9AT is a unidirectional TVS diode, indicated by the "A" (not "CA") suffix and cathode band marking. Bidirectional variants in the same family use the "CA" suffix (e.g., SMCG8.0CA). Using SMCG8.0A-E3/9AT in reverse-biased configurations risks permanent breakdown above 8.0 V. For bidirectional protection, select SMCG8.0CA-E3/9AT or equivalent, which exhibits symmetric VBR in both directions as confirmed in the Electrical Characteristics table.
