Product details
Overview
SMCG13A-E3/9AT from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) in the SMCG (DO-215AB) package, featuring a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 21.5 V clamping voltage (VC) at 69.8 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with a 10/1000 µs waveform. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCG13A-E3/9AT datasheet, SMCG13A-E3/9AT pinout, SMCG13A-E3/9AT application, or SMCG13A-E3/9AT equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), mounting pad layout guidance, and direct alternatives for overvoltage protection design.
Technical Context
The SMCG13A-E3/9AT operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 14.4–15.9 V breakdown range. Its glass-passivated junction ensures stable clamping performance under repetitive transients, with low incremental surge resistance enabling consistent 21.5 V clamping at 69.8 A IPPM.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it meets MSL Level 1 per J-STD-020 (peak reflow 260 °C) and is AEC-Q101 qualified for automotive-grade reliability. Polarity is marked by a cathode band; no marking applies to bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 14.4 V / 15.9 V at 1 mA - guaranteed avalanche initiation window for predictable turn-on |
| VC @ IPPM | 21.5 V at 69.8 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 1500 W - peak transient energy absorption capability under standardized waveform |
| RθJA | 75 °C/W - thermal resistance from junction to ambient on recommended PCB pad layout |
| TJ max | +150 °C - maximum allowable junction temperature for sustained operation |
| ID @ VWM | 1.0 µA - ultra-low leakage at stand-off voltage, minimizing standby power loss |

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 PPPM (400 W), but lower 400 W rating and SMA (DO-214AC) package | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost or board space is critical and automotive qualification is unnecessary |
| SMCJ13A-E3/9AT | Same VWM (13 V), higher PPPM (1500 W), but larger SMC (DO-214AB) package and higher RθJA (50 °C/W) | Better thermal margin on minimal copper; requires larger footprint than SMCG | Select when higher surge repetition rate or extended thermal cycling is required |
Compared with SMCG13A-E3/9AT, SMAJ13A-E3/57T offers reduced surge capacity and no automotive qualification, while SMCJ13A-E3/9AT delivers identical electrical protection with greater thermal mass but occupies ~30% more PCB area-making SMCG13A-E3/9AT optimal for space-constrained AEC-Q101 designs.

FAQ
What is the clamping voltage of SMCG13A-E3/9AT at its rated peak pulse current?
The SMCG13A-E3/9AT has a maximum clamping voltage (VC) of 21.5 V at 69.8 A peak pulse current (IPPM), measured using the standardized 10/1000 µs waveform. This value ensures downstream components see limited overvoltage during surge events. The SMCG13A-E3/9AT maintains this clamping performance across its qualified operating temperature range and is validated per AEC-Q101 stress tests.
Is SMCG13A-E3/9AT suitable for automotive applications?
Yes, SMCG13A-E3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including engine control modules, body electronics, and ADAS sensor interfaces. Its glass-passivated junction, MSL Level 1 reflow compatibility, and -55 °C to +150 °C operating range meet stringent automotive reliability requirements. The SMCG13A-E3/9AT data sheet confirms qualification per AEC-Q101 test conditions.
What does the "E3/9AT" suffix indicate in SMCG13A-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 with a base quantity of 3500 units. This format supports high-volume automated SMT placement. The SMCG13A-E3/9AT ordering code is fully aligned with Vishay's documented packaging nomenclature in Document Number 88457.
How does SMCG13A-E3/9AT differ from bidirectional variants like SMCG13CA?
SMCG13A-E3/9AT is unidirectional with cathode-band polarity and conducts only in reverse bias above VBR; SMCG13CA is bidirectional, symmetrical in both directions, and lacks polarity marking. Their VWM (13 V), VBR (14.4–15.9 V), and PPPM (1500 W) match, but SMCG13A-E3/9AT is used for line-to-ground protection, whereas SMCG13CA suits AC line or differential signal protection. The SMCG13A-E3/9AT datasheet confirms unidirectional behavior and cathode identification.
What PCB layout guidance applies to SMCG13A-E3/9AT for optimal thermal performance?
For optimal thermal performance, SMCG13A-E3/9AT must be mounted on minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as specified in the Vishay datasheet. This layout achieves the published RθJA of 75 °C/W. Reducing pad size increases junction temperature and de-rates surge capability. The SMCG13A-E3/9AT mechanical drawing confirms pad dimensions and gull-wing lead spacing compatible with standard SMT stencil designs.
