Product details
Overview
SMCG6.0CA-E3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for clamping voltage transients on signal or power lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (10/1000 µs), 145.6 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge. It is AEC-Q101 qualified and used for automotive sensor line protection.
For engineers reviewing the SMCG6.0CA-E3/9AT datasheet, SMCG6.0CA-E3/9AT pinout, SMCG6.0CA-E3/9AT application, or SMCG6.0CA-E3/9AT equivalent, key selection criteria include bidirectional clamping capability, 1500 W surge rating, DO-215AB thermal performance (RθJA = 75 °C/W), AEC-Q101 qualification, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity dependence. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, enabling consistent clamping voltage under repetitive surge stress.
Designed for surface-mount use in high-reliability environments, it meets MSL Level 1 per J-STD-020 (260 °C peak reflow), supports 150 °C maximum junction temperature, and delivers fast response time (<1 ns) to ESD and lightning-induced surges per IEC 61000-4-2/4-5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal integrity margin for 5 V systems. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown range ensures reliable turn-on across process variation and temperature. |
| VC @ IPPM | ≤10.3 V at 145.6 A - Clamping voltage under full 1500 W surge; limits downstream IC stress during ISO 7637-2 Pulse 1/2a/5a events. |
| PPPM | 1500 W (10/1000 µs) - Peak surge handling capacity suitable for automotive load-dump and inductive switching protection. |
| TJ max. | +150 °C - Enables operation in under-hood automotive environments and industrial enclosures without derating. |
| RθJA | 75 °C/W - Thermal resistance measured on 8.0 mm × 8.0 mm copper pads; informs PCB thermal design for sustained 6.5 W dissipation. |

| Cathode | Transient current entry (positive half-cycle) | Second terminal of symmetrical junction; conducts during positive overvoltage events; no band marking on CA variants. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per stress test plan. |
| Glass-passivated junction | Ensures stable VBR tolerance and long-term leakage stability under humidity and thermal bias stress. |
| MSL Level 1 rating | Supports standard SMT reflow profiles up to 260 °C peak without moisture-induced popcorn failure. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., EFT bursts), improving clamping precision. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/57T | Unidirectional; same VWM/VBR/PPPM but single-polarity clamping; SMA (DO-214AC) package. | Requires external polarity management; unsuitable for AC-coupled or floating differential lines. | Select only when circuit topology guarantees unidirectional surge direction and board space allows larger SMA footprint. |
| SMCJ6.0CA | Bidirectional; higher PPPM (1500 W same), but larger SMC (DO-214AB) package; RθJA ≈ 35 °C/W. | Higher thermal mass enables higher average power handling but requires more PCB area and may not fit tight automotive layouts. | Prefer for industrial power supplies needing extended surge duty cycle; avoid where DO-215AB height or pad area is constrained. |
Compared with SMAJ6.0A-E3/57T and SMCJ6.0CA, SMCG6.0CA-E3/9AT uniquely combines bidirectional clamping, AEC-Q101 qualification, DO-215AB compactness (0.260" × 0.125"), and MSL Level 1 suitability-making it optimal for space-constrained, automotive-grade signal line protection where polarity-agnostic surge immunity is mandatory.

FAQ
What is the clamping voltage of SMCG6.0CA-E3/9AT under maximum rated surge current?
The SMCG6.0CA-E3/9AT clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 145.6 A (10/1000 µs waveform). This value is guaranteed per the Vishay datasheet and reflects worst-case device behavior under standardized surge conditions, ensuring downstream ICs remain within safe operating voltage limits during transient events.
Is SMCG6.0CA-E3/9AT suitable for automotive applications?
Yes, SMCG6.0CA-E3/9AT is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including glass-passivated junction, MSL Level 1 reflow compatibility, -55 °C to +150 °C operating range, and validated surge performance-meets requirements for engine control units, ADAS sensors, and body electronics where reliability under harsh conditions is mandatory.
How does the bidirectional design of SMCG6.0CA-E3/9AT affect circuit layout?
The bidirectional design of SMCG6.0CA-E3/9AT eliminates polarity sensitivity: no cathode band marking is present, and either terminal can connect to signal or ground. This simplifies PCB routing for AC-coupled or floating differential lines (e.g., CAN, RS-485), removes risk of reverse installation, and avoids need for duplicate unidirectional devices in symmetric protection schemes.
What is the thermal resistance of SMCG6.0CA-E3/9AT, and how does it impact PCB design?
SMCG6.0CA-E3/9AT 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. To maintain TJ ≤ 150 °C at full 6.5 W steady-state dissipation, designers must allocate sufficient copper area and consider airflow or adjacent heat sources-especially in sealed automotive enclosures.
Does SMCG6.0CA-E3/9AT meet RoHS and halogen-free requirements?
Yes, the "E3" suffix in SMCG6.0CA-E3/9AT indicates RoHS-compliant, industrial-grade construction with matte tin-plated leads. It meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability. While not halogen-free (that requires "M3" suffix), it satisfies standard environmental compliance for most automotive and industrial programs.
