Product details
Overview
SMCG6.0CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) in the SMCG (DO-215AB) surface-mount 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 in automotive sensor line protection.
For engineers reviewing the SMCG6.0CA-E3/57T datasheet, SMCG6.0CA-E3/57T pinout, SMCG6.0CA-E3/57T application, or SMCG6.0CA-E3/57T 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 assembly on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCG6.0CA-E3/57T operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity marking. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for protecting sensitive inputs against ESD and load-switching spikes.
Designed for surface-mount use on PCBs with defined 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, it delivers 1500 W peak pulse power under standardized 10/1000 µs waveform conditions and derates linearly above 25 °C ambient per Fig. 2 - supporting robust operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 6.67 V / 7.37 V at IT = 10 mA - ensures reliable avalanche initiation across process variation |
| VC @ IPPM | ≤10.3 V at 145.6 A - defines worst-case clamped voltage seen by protected circuitry |
| PPPM | 1500 W (10/1000 µs) - determines energy-handling capacity for common surge standards (IEC 61000-4-5) |
| ID @ VWM | 1000 µA max - low leakage preserves signal integrity in high-impedance interfaces |
| TJ max. | +150 °C - supports under-hood automotive environments and industrial enclosures |
| Package | SMCG (DO-215AB) - low-profile, MSL Level 1, compatible with reflow profiles peaking at 260 °C |
Pinout & Package
SMCG6.0CA-E3/57T uses the SMCG (DO-215AB) surface-mount package: a gull-wing, dual-terminal outline with no polarity marking (bidirectional). Terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (symmetrical) | Bidirectional conduction path - either terminal may serve as anode or cathode depending on transient polarity |
| Terminal 2 | Anode/Cathode (symmetrical) | Identical electrical role to Terminal 1; no functional distinction - device mounts without orientation constraint |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, ADAS sensors, and infotainment power rails |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-to-line, 2 Ω source impedance) without degradation |
| Glass-passivated junction | Ensures stable VBR over temperature and lifetime, with <1 ns response time to fast transients |
| MSL Level 1 rating | Enables standard SMT reflow without dry-pack or baking - compatible with J-STD-020 peak of 260 °C |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed industrial and automotive electronics housings |
Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting LIN or SENT bus lines in engine temperature or pressure sensors exposed to load-dump and inductive switching noise. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential pair or single-ended signal line to clamp ±100 V transients. Use Value: Limits voltage excursion to ≤10.3 V during 145.6 A surge, preventing damage to MCU analog front-end or transceiver input stages. |

Use Scenario: Primary protection for ADSL/VDSL line drivers connected to outside plant wiring susceptible to lightning-induced surges. IC Role / Device Role / Timing Role: First-stage bidirectional clamp before transformer coupling, rated for repeated 1500 W pulses. Use Value: Survives multiple 10/1000 µs surges up to 145.6 A without parameter shift, verified per Telcordia GR-1089-CORE. |
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 lacks bidirectional symmetry; lower IPPM (135 A) | Requires correct polarity placement; unsuitable for AC-coupled or floating lines | Select only when polarity is fixed and board layout allows orientation-sensitive mounting |
| SMCJ6.0CA | Same bidirectional function but in larger DO-214AB (SMC) package; higher thermal mass (RθJA = 30 °C/W) | Better sustained power handling but occupies ~2.5× PCB area; not RoHS-compliant in base version | Prefer for high-reliability industrial designs where footprint is secondary to thermal margin |
Compared with SMAJ6.0A-E3/57T and SMCJ6.0CA, the SMCG6.0CA-E3/57T uniquely balances AEC-Q101 qualification, DO-215AB compactness, and true bidirectional clamping - making it optimal for space-constrained automotive and portable telecom modules requiring zero-orientation assembly.

FAQ
What does the "CA" suffix indicate in SMCG6.0CA-E3/57T?
The "CA" suffix denotes a bidirectional configuration - meaning the SMCG6.0CA-E3/57T clamps voltage transients equally in both polarities, with no cathode marking required. This distinguishes it from unidirectional variants like SMCG6.0A-E3/57T, which require correct polarity orientation during placement. The SMCG6.0CA-E3/57T is tested and specified for symmetrical electrical characteristics in both directions per ANSI/IEEE C62.35.
Is SMCG6.0CA-E3/57T suitable for IEC 61000-4-5 surge testing?
Yes - the SMCG6.0CA-E3/57T is rated for 1500 W peak pulse power with a 10/1000 µs waveform, directly aligning with IEC 61000-4-5 Level 4 (4 kV line-to-line, 2 Ω source impedance). When mounted per the recommended 8.0 mm × 8.0 mm copper pad layout, it reliably clamps to ≤10.3 V during full-surge events, protecting downstream ICs without degradation across multiple strikes.
Does SMCG6.0CA-E3/57T require orientation during PCB assembly?
No - the SMCG6.0CA-E3/57T is a bidirectional device with identical terminals; there is no anode/cathode distinction or polarity marking. It can be placed in either orientation on the PCB without affecting electrical performance. This simplifies automated pick-and-place and eliminates orientation-related assembly errors - a key advantage over unidirectional TVS diodes like SMCG6.0A-E3/57T.
What is the maximum operating temperature for SMCG6.0CA-E3/57T?
The SMCG6.0CA-E3/57T has a maximum junction temperature (TJ max.) of +150 °C and an operating junction/storage temperature range of –55 °C to +150 °C. Its thermal resistance (RθJA = 75 °C/W) assumes mounting on 0.31" × 0.31" copper pads; actual operating temperature must be calculated using ambient temperature, power dissipation, and layout-specific thermal impedance - especially critical in sealed automotive enclosures.
How does the "E3/57T" suffix affect compliance and packaging of SMCG6.0CA-E3/57T?
The "E3" suffix indicates RoHS-compliant, industrial-grade construction with matte tin-plated leads; "57T" specifies packaging in 7-inch plastic tape-and-reel format containing 850 units. This configuration meets JESD 201 Class 2 whisker resistance and J-STD-020 reflow requirements (peak 260 °C), ensuring compatibility with high-volume SMT lines and long-term reliability in non-automotive applications.
