Product details
Overview
SMCG13A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMCG (DO-215AB) package, with a standoff voltage of 13 V, breakdown voltage range 14.4–15.9 V at 1.0 mA, clamping voltage of 21.5 V at 69.8 A (10/1000 µs), peak pulse power rating of 1500 W, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCG13A-E3/57T datasheet, SMCG13A-E3/57T pinout, SMCG13A-E3/57T application, or SMCG13A-E3/57T equivalent, this device is selected for robust overvoltage protection on DC power rails and signal lines where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.42), and high surge current handling are required in space-constrained automotive and industrial designs.
Technical Context
The SMCG13A-E3/57T operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its specified breakdown range (14.4–15.9 V). It uses glass-passivated junction technology to ensure stable VBR tolerance and long-term reliability under repetitive surge stress.
Its thermal resistance (RθJA = 75 °C/W) and maximum junction temperature (150 °C) support operation in high-ambient environments when mounted per recommended 8.0 mm × 8.0 mm copper pads. The device complies with J-STD-020 MSL Level 1 and passes JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 12 V automotive systems. |
| VBR min/max | 14.4 V / 15.9 V at 1.0 mA - Tight breakdown window ensures predictable turn-on and minimal variation across production lots. |
| VC @ IPPM | 21.5 V at 69.8 A (10/1000 µs) - Clamping voltage limits downstream IC stress during ISO 7637-2 Pulse 1/2a/5a transients. |
| PPPM | 1500 W - Sustains high-energy surges without failure; enables single-device protection for 12 V CAN/LIN bus power inputs. |
| ID @ VWM | 1.0 µA - Ultra-low leakage preserves battery life in always-on automotive modules (e.g., body control units). |
| TJ max | +150 °C - Supports under-hood deployment in engine control units and ADAS sensors without derating. |
| Package | SMCG (DO-215AB) - Low-profile gull-wing leaded package optimized for automated SMT placement and reflow compatibility. |
Pinout & Package
SMCG13A-E3/57T uses the SMCG (DO-215AB) package: surface-mount gull-wing leads, cathode marked by a band on the case, polarity-critical for unidirectional operation. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal per Vishay's thermal design guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current path / low-side reference | Connected to ground or low-impedance return path; forms clamping loop with cathode during transient events. |
| Cathode | Protected line input / high-side connection | Connected to the line being protected (e.g., 12 V supply rail); band marking identifies this terminal. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan. |
| Glass passivated junction | Ensures stable electrical parameters over time and humidity exposure; eliminates risk of junction corrosion in harsh environments. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., load dump), improving protection margin for downstream MOSFETs. |
| 1500 W peak pulse power | Handles full ISO 16750-2 load dump pulses (up to 35 V, 400 ms) when used with appropriate upstream impedance. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V supply inputs in engine control units (ECUs) against ISO 7637-2 Pulse 5a load dump transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between battery rail and DC-DC converter input. Use Value: Limits transient voltage to ≤21.5 V, preventing damage to 36 V-rated input stages while maintaining system uptime. | Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop) in factory automation sensors from ESD and inductive switching noise. IC Role / Device Role / Timing Role: Bidirectional-capable but used unidirectionally across signal-to-ground; absorbs ±8 kV contact ESD per IEC 61000-4-2. Use Value: Sub-1 ns response prevents latch-up in precision op-amps and ADC drivers without adding series resistance or bandwidth degradation. |
| Telecom DC Power Interface | Consumer Device USB Port Protection |
Use Scenario: Safeguarding 48 V PoE-powered equipment front-end rectifiers from lightning-induced surges on Ethernet cables. IC Role / Device Role / Timing Role: Primary clamping device on DC input after bridge rectifier; coordinated with MOV and gas discharge tube. Use Value: 1500 W rating handles multi-pulse surge events per IEC 61000-4-5; low clamping ratio reduces stress on downstream TVS arrays. | Use Scenario: Protecting USB VBUS line in portable medical monitors from accidental 12 V adapter misconnection or hot-swap transients. IC Role / Device Role / Timing Role: Unidirectional TVS between VBUS and ground, sized to clamp at 21.5 V before USB PHY IC damage threshold. Use Value: 1.0 µA leakage avoids battery drain in standby mode; RoHS-compliant matte tin plating ensures solder joint integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/57T | Same VWM (13 V) and VC (21.5 V), but lower PPPM (400 W) and smaller SMA (DO-214AC) package. | Limited to lower-energy transients; unsuitable for automotive load dump or telecom surge standards. | Select SMAJ13A-E3/57T only for cost-sensitive consumer applications with <500 W surge requirements. |
| SMCJ13A-E3/57T | Same VWM (13 V) and PPPM (1500 W), but larger SMC (DO-214AB) package and higher RθJA (60 °C/W vs. 75 °C/W). | Requires more PCB area; thermal performance inferior in dense layouts despite same power rating. | Choose SMCJ13A-E3/57T only if existing SMC footprint reuse is mandatory and thermal margin allows. |
Compared with SMAJ13A-E3/57T and SMCJ13A-E3/57T, the SMCG13A-E3/57T delivers identical electrical protection performance in a lower-profile, AEC-Q101-qualified package with superior automated placement yield-making it the preferred choice for next-generation automotive and space-constrained industrial modules.

FAQ
What is the clamping voltage of SMCG13A-E3/57T and how is it measured?
The SMCG13A-E3/57T has a maximum clamping voltage (VC) of 21.5 V, measured at a peak pulse current (IPPM) of 69.8 A using the standardized 10/1000 µs double-exponential waveform per ANSI/IEEE C62.35. This value is guaranteed across temperature and production lot, ensuring consistent protection behavior in real-world surge events like ISO 7637-2 Pulse 5a.
Is SMCG13A-E3/57T suitable for automotive applications?
Yes, SMCG13A-E3/57T carries AEC-Q101 qualification and meets MSL Level 1 per J-STD-020 with 260 °C peak reflow tolerance. Its 1500 W peak pulse power, 150 °C maximum junction temperature, and glass-passivated junction make it suitable for under-hood and chassis-mounted automotive modules including body control units and ADAS sensors.
What does the "E3/57T" suffix mean in SMCG13A-E3/57T?
The "E3" denotes RoHS-compliant, industrial-grade matte tin plating meeting JESD201 Class 2 whisker resistance; "57T" specifies packaging in 7-inch diameter plastic tape and reel with 850 units per reel. This configuration supports high-volume SMT assembly and ensures traceable, compliant sourcing for production programs.
How does SMCG13A-E3/57T differ from bidirectional variants like SMCG13CA?
SMCG13A-E3/57T is unidirectional with cathode marking and forward conduction capability, while SMCG13CA is bidirectional with no polarity marking and symmetrical clamping in both directions. The SMCG13A-E3/57T offers lower leakage (1.0 µA vs. 2.0 µA for SMCG13CA) and is preferred for DC rail protection where polarity is fixed and leakage sensitivity is critical.
What PCB layout guidance applies to SMCG13A-E3/57T for optimal thermal performance?
Vishay specifies mounting SMCG13A-E3/57T on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve the rated RθJA of 75 °C/W. Minimum trace width should be ≥0.5 mm, and thermal vias under pads are recommended for high-duty-cycle surge environments. Avoid solder mask dams over thermal pads to ensure full copper exposure.
