Product details
Overview
SMCG6.0CA-M3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection on signal and 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 (PPPM), clamping voltage of 10.3 V at 145.6 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCG6.0CA-M3/9AT datasheet, SMCG6.0CA-M3/9AT pinout, SMCG6.0CA-M3/9AT application, or SMCG6.0CA-M3/9AT equivalent, this device serves as a halogen-free, RoHS-compliant, surface-mount TVS for bidirectional surge suppression in automotive sensor interfaces, industrial I/O ports, and telecom line protection where low clamping and fast response (<1 ns) are critical.
Technical Context
The SMCG6.0CA-M3/9AT operates as a bidirectional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress.
Designed for 10/1000 µs waveform compliance, it delivers 145.6 A peak pulse current (IPPM) while maintaining 10.3 V clamping voltage - critical for safeguarding 5 V logic interfaces and analog front-ends. Thermal resistance RθJA is 75 °C/W, and maximum junction temperature is rated to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin for 5 V systems. |
| VBR min/max | 6.67 V / 7.37 V at 10 mA - Tight breakdown window ensures predictable turn-on across production lots and temperature. |
| VC @ IPPM | 10.3 V at 145.6 A - Clamping voltage limits downstream IC stress during 1500 W transients (10/1000 µs). |
| PPPM | 1500 W - Peak surge power handling capability per IEEE C62.35; supports IEC 61000-4-5 Level 4 immunity. |
| ID @ VWM | 1000 µA max - Low leakage preserves signal integrity and battery life in always-on sensor circuits. |
| TJ max | +150 °C - Enables deployment in under-hood automotive environments and high-temperature industrial enclosures. |
| Package | SMCG (DO-215AB) - Surface-mount gull-wing package with 8.0 mm × 8.0 mm copper pad footprint for optimal thermal dissipation. |
Pinout & Package
SMCG6.0CA-M3/9AT uses the SMCG (DO-215AB) package: a bidirectional, unmarked, two-terminal surface-mount device with gull-wing leads. No polarity marking is present, consistent with bidirectional TVS construction. Terminals are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (symmetrical) | Bidirectional conduction path - either terminal functions identically; no cathode band marking. |
| Terminal 2 | Anode/Cathode (symmetrical) | Electrically identical to Terminal 1; enables placement flexibility and eliminates orientation constraints on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for ADAS sensor modules and body control units. |
| Halogen-free & RoHS compliant (M3 suffix) | Meets IEC 61249-2-21 and JEDEC J-STD-201 Class 2 whisker resistance - required for Tier 1 automotive supply chains. |
| Low incremental surge resistance | Enables tighter clamping (10.3 V) versus competing 6 V TVS devices - reduces voltage overshoot on protected ICs by up to 1.8 V. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning - simplifies SMT line integration and eliminates moisture sensitivity delays. |
| Glass-passivated junction | Improves long-term stability of VBR and leakage under thermal/humidity stress - critical for 15-year automotive service life. |
Applications
| Automotive Sensor Protection | Industrial Digital I/O Protection |

Use Scenario: Adding robust ESD and surge immunity to USB 2.0 data lines in smart home hubs subjected to user-handling events. IC Role / Device Role: Bidirectional TVS across D+ and D− lines, upstream of USB controller PHY. Use Value: 1000 µA max leakage at 6.0 V avoids signal integrity degradation; DO-215AB footprint allows routing beneath USB connector. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-M3/867 | Unidirectional; 6.67–7.37 V VBR; same PPPM (1500 W) but higher VC (10.5 V); SMA package (DO-214AC). | Requires polarity-aware layout; unsuitable for AC or floating lines without series diodes. | Select when protecting DC-biased lines where unidirectional clamping suffices and board space permits larger SMA footprint. |
| SMCJ6.0CA-M3/867 | Bidirectional; same VWM/VBR range; higher PPPM (1500 W); VC = 10.3 V; larger SMC (DO-214AB) package with higher thermal mass. | Higher RθJA (50 °C/W vs. 75 °C/W) but better surge endurance due to larger junction area. | Prefer for high-reliability industrial power rails where sustained surge repetition is expected and PCB real estate allows SMC outline. |
Compared with SMAJ6.0A-M3/867 and SMCJ6.0CA-M3/867, the SMCG6.0CA-M3/9AT offers identical electrical protection performance in a smaller DO-215AB footprint, optimized for dense automotive PCBs and automated placement - with no polarity constraints and full AEC-Q101 validation.

FAQ
What does the "CA" suffix indicate in SMCG6.0CA-M3/9AT?
The "CA" suffix denotes a bidirectional configuration - meaning the SMCG6.0CA-M3/9AT provides symmetrical transient suppression in both polarities, with identical breakdown and clamping behavior regardless of voltage polarity. This eliminates the need for polarity-aware PCB layout and makes it ideal for AC-coupled signals, differential buses, and floating sensor outputs where directionality cannot be assumed.
Is SMCG6.0CA-M3/9AT suitable for automotive applications?
Yes, SMCG6.0CA-M3/9AT is AEC-Q101 qualified and explicitly rated for automotive use. It meets requirements for temperature cycling, high-temperature reverse bias (HTRB), and mechanical shock - validated for deployment in engine control units, ADAS camera modules, and body electronics. The M3 suffix confirms halogen-free, RoHS-compliant construction required by major Tier 1 suppliers.
How does the SMCG6.0CA-M3/9AT compare to SMAJ6.0CA in terms of package and performance?
SMCG6.0CA-M3/9AT uses the smaller DO-215AB (SMCG) package versus SMAJ6.0CA's DO-214AC (SMA), offering ~30% smaller footprint and lower profile. Both deliver 1500 W PPPM and 10.3–10.5 V clamping, but SMCG6.0CA-M3/9AT has higher thermal resistance (75 °C/W vs. ~60 °C/W), making it best suited for single-event surge rather than repetitive duty. Its bidirectional symmetry also simplifies layout over SMAJ variants that require polarity alignment.
What is the maximum clamping voltage of SMCG6.0CA-M3/9AT under surge conditions?
The maximum clamping voltage (VC) of SMCG6.0CA-M3/9AT is 10.3 V at its rated peak pulse current (IPPM) of 145.6 A, tested with a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range (–55 °C to +150 °C) and ensures protected circuitry remains below the absolute maximum ratings of common 5 V logic and analog ICs during surge events.
Does SMCG6.0CA-M3/9AT require special PCB layout considerations?
Yes - Vishay specifies mounting on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve rated 1500 W PPPM and thermal performance. Use of smaller pads reduces surge current capability and increases clamping voltage. Also, because SMCG6.0CA-M3/9AT is bidirectional and unmarked, orientation is irrelevant - eliminating polarity verification steps during assembly.
