Product details
Overview
SMCG8.0A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in DO-215AB (SMCG) package, with 8.0 V stand-off voltage, 13.6 V clamping voltage at 50 A peak pulse current, 1500 W peak pulse power rating, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG8.0A-E3/57T datasheet, SMCG8.0A-E3/57T pinout, SMCG8.0A-E3/57T application, or SMCG8.0A-E3/57T equivalent, this device is selected for robust overvoltage protection on DC power rails and low-voltage signal lines where fast response (<1 ns), low clamping ratio (1.7×VWM), and high surge current capability are required.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping protector: under normal conditions it presents high impedance (>1000 µA leakage at 8.0 V), then rapidly avalanches below 9.83 V breakdown to limit transients. Its glass-passivated junction ensures stable VBR tolerance (±5%) and long-term reliability across -55 °C to +150 °C junction temperature range.
Designed for automated SMT assembly, the SMCG8.0A-E3/57T uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, meets UL 94 V-0 flammability, and is rated MSL Level 1 - enabling reflow without moisture sensitivity concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 8.89 V / 9.83 V at 1.0 mA - tight breakdown window ensures predictable turn-on threshold |
| VC @ IPPM | 13.6 V at 50 A (10/1000 µs) - low clamping voltage protects downstream 3.3 V or 5 V ICs |
| PPPM | 1500 W - handles high-energy transients such as ISO 7637-2 Pulse 1/2a/5a in automotive systems |
| ID @ VWM | 1.0 µA - ultra-low leakage preserves battery life in always-on circuits |
| TJ max | +150 °C - supports under-hood automotive placement and industrial high-temp environments |
| RθJA | 75 °C/W - thermal performance validated on 8.0 mm × 8.0 mm copper pads per terminal |
Pinout & Package
Package: DO-215AB (SMCG) - molded surface-mount case with gull-wing leads, 0.310" × 0.400" footprint, 0.058" lead width, cathode band marking on unidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-impedance return path; forms current sink during clamping |

| AEC-Q101 qualified | Validated for automotive electronics including engine control, body modules, and ADAS sensors |
| Glass passivated junction | Ensures stable VBR over lifetime and resistance to humidity-induced parameter drift |
| MSL Level 1 rating | Enables single-reflow assembly without baking; compatible with standard Pb-free reflow profiles |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD > 30 kV) |
| UL 94 V-0 molding compound | Meets flame-retardancy requirements for enclosed industrial and automotive enclosures |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator switching transients. IC Role / Device Role / Timing Role: Shunt-clamping TVS placed between power rail and chassis ground, responding within <1 ns to clamp spikes up to 100 V. Use Value: Limits rail voltage to ≤13.6 V during 1500 W surges, preventing damage to MCU, CAN transceivers, and voltage regulators. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Bidirectional-capable variant not used; SMCG8.0A-E3/57T serves as unidirectional clamp on 5 V sensor supply line. Use Value: With only 1.0 µA leakage at 8.0 V, it avoids loading precision sensor references while suppressing 1 kV EFT bursts. |
| Consumer USB Power Delivery | Telecom Base Station Control Lines |
Use Scenario: Overvoltage protection on VBUS line of USB-C PD adapters handling up to 20 V negotiation. IC Role / Device Role / Timing Role: Standoff-rated at 8.0 V, placed upstream of buck converter to absorb inductive kickback from hot-swap MOSFETs. Use Value: Clamps 50 A transients to 13.6 V, preserving integrity of USB PD controller ICs and Type-C port logic. | Use Scenario: Protecting RS-485/RS-232 control lines in outdoor telecom cabinets exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS on +3.3 V bias rail feeding level translators and line drivers. Use Value: 1500 W PPPM rating sustains multiple 10/1000 µs surges per IEC 61000-4-5 Level 4 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 |
|---|---|---|---|
| SMAJ8.0A-E3/57T | DO-214AC (SMA) package; higher RθJA (110 °C/W); same VWM/VBR/VC specs | Larger footprint (4.5 mm × 2.7 mm vs. SMCG's 7.87 mm × 10.16 mm); lower power density | Select when legacy SMA layout exists or board space allows larger device |
| SMCJ8.0A-E3/57T | DO-214AB (SMC) package; 1500 W rating but higher VC = 13.4 V at 64.5 A; same VWM | Higher IPPM enables longer surge duration handling; requires larger pad area (10.16 mm × 7.11 mm) | Prefer for systems requiring margin beyond 50 A peak or extended thermal mass |
Compared with SMAJ8.0A-E3/57T and SMCJ8.0A-E3/57T, the SMCG8.0A-E3/57T delivers identical electrical protection in a lower-profile, AEC-Q101-qualified package optimized for high-density automotive PCBs - offering superior thermal performance (RθJA = 75 °C/W) and tighter mounting constraints than SMA or SMC alternatives.

FAQ
What is the clamping voltage of SMCG8.0A-E3/57T at its rated peak pulse current?
The SMCG8.0A-E3/57T has a maximum clamping voltage (VC) of 13.6 V when subjected to a 10/1000 µs waveform at 50 A peak pulse current. This value is measured under standardized test conditions with 8.0 mm × 8.0 mm copper pads per terminal and confirms its ability to protect 5 V and 3.3 V systems during high-energy transients. The SMCG8.0A-E3/57T maintains this clamping performance across its full operating temperature range.
Is SMCG8.0A-E3/57T suitable for automotive applications?
Yes, SMCG8.0A-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor modules. Its construction features glass-passivated junctions, MSL Level 1 reflow compatibility, and operation from -55 °C to +150 °C - all validated per automotive stress testing protocols. The SMCG8.0A-E3/57T meets ISO 7637-2 Pulse 5a requirements when applied with proper PCB layout.
What does the "E3/57T" suffix indicate in SMCG8.0A-E3/57T?
The "E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads; "57T" specifies packaging in 7-inch diameter plastic tape and reel with 850 units per reel. This ordering code reflects Vishay's standardized nomenclature for environmental compliance and logistics configuration - distinct from HE3 (AEC-Q101 qualified) or M3 (halogen-free) variants. The SMCG8.0A-E3/57T is not AEC-Q101 qualified unless specified as HE3.
How does SMCG8.0A-E3/57T differ from bidirectional TVS diodes like SMCG8.0CA?
The SMCG8.0A-E3/57T is unidirectional and features a cathode band marking; it conducts only in reverse breakdown, making it ideal for DC rail protection. In contrast, SMCG8.0CA is bidirectional with no polarity marking and symmetrical clamping in both directions - suited for AC lines or differential signals. Their VWM (8.0 V), VBR (8.89–9.83 V), and VC (13.6 V) match, but SMCG8.0A-E3/57T cannot replace SMCG8.0CA in AC-coupled applications without circuit redesign.
What is the thermal resistance of SMCG8.0A-E3/57T, and how does it affect layout?
The SMCG8.0A-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's datasheet; reducing pad size increases RθJA and risks thermal runaway during repeated surges. For reliable operation, maintain full copper pour under both terminals and avoid narrow traces - critical for sustaining the SMCG8.0A-E3/57T's 1500 W rating.
