Product details
Overview
SMCG60CA-M3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, with 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamping voltage of 96 V at 15.5 A IPPM. It protects signal lines and power rails in automotive sensor interfaces against ESD and inductive switching transients.
For engineers reviewing the SMCG60CA-M3/9AT datasheet, SMCG60CA-M3/9AT pinout, SMCG60CA-M3/9AT application, or SMCG60CA-M3/9AT equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), halogen-free compliance (M3 suffix), and bidirectional clamping behavior for robust overvoltage design.
Technical Context
The SMCG60CA-M3/9AT operates as a bidirectional avalanche diode, symmetrically clamping voltage surges above ±66.7 V in both polarities. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 μA at VWM), while the DO-215AB package supports automated SMT placement and meets MSL level 1 (260 °C reflow).
Designed for high-energy transient suppression, it handles 1500 W (10/1000 μs waveform) with a clamping ratio of 1.44 (VC/VBR min), and features low incremental surge resistance to minimize voltage overshoot during fast transients like ISO 7637-2 pulse 1/2a/5a.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 66.7 V / 73.7 V - Breakdown occurs within this range at 1 mA test current, defining turn-on threshold |
| VC @ IPPM | 96 V at 15.5 A - Clamped voltage during 10/1000 μs surge, limiting stress on downstream ICs |
| PPPM | 1500 W - Peak transient power it can absorb without failure under standardized surge waveform |
| ID @ VWM | ≤1.0 μA - Ultra-low leakage ensures minimal standby power loss and signal integrity |
| RθJA | 75 °C/W - Thermal resistance enables reliable operation up to +150 °C junction temperature with standard PCB copper pads |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, gull-wing leaded case with matte tin-plated terminals, 8.0 mm × 8.0 mm copper pad layout recommended per datasheet fig. 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Terminal A | Bidirectional symmetry means no polarity marking; either terminal serves as anode or cathode depending on transient polarity |
| Cathode | Terminal K | Same physical terminal as Anode due to bidirectional construction; no band marking on device body |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, ADAS sensors, and infotainment power rails |
| Halogen-free (M3 suffix) | Complies with IEC 61249-2-21 and RoHS, enabling use in environmentally regulated industrial and automotive systems |
| MSL Level 1 | Unlimited floor life and compatibility with standard 260 °C Pb-free reflow profiles without baking |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes overvoltage margin required for protected ICs, reducing need for derating in 12 V/24 V systems |
Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting LIN/CAN transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential bus lines or supply-to-ground to clamp transients before they reach PHY layer. Use Value: Withstands 1500 W surges and maintains <1.0 μA leakage at 60 V, preserving signal fidelity and meeting ISO 16750-2 pulse requirements. | Use Scenario: Safeguarding RS-485/CAN FD physical layer ICs in factory automation controllers exposed to motor drive noise and relay switching. IC Role / Device Role / Timing Role: Placed between bus lines (A/B) and ground to suppress common-mode transients without affecting DC bias or data eye integrity. Use Value: 96 V clamping at 15.5 A ensures protected receivers see <±100 V spikes, extending lifetime of isolated transceivers in harsh EMI environments. |
| Consumer Power Adapter Input | Telecom PoE Surge Protection |
Use Scenario: Front-end protection for AC-DC adapters and USB-C PD chargers subjected to lightning-induced surges on mains input. IC Role / Device Role / Timing Role: Connected line-to-line or line-to-earth to limit let-through energy during 10/1000 μs surges per IEC 61000-4-5. Use Value: 1500 W PPPM rating and 75 °C/W RθJA allow sustained operation without thermal runaway under repeated surge events. | Use Scenario: Secondary-side transient suppression on Power over Ethernet (PoE) data lines (pins 1–2, 3–6) in IP cameras and wireless access points. IC Role / Device Role / Timing Role: Bidirectional clamping across differential pairs to prevent damage to Ethernet PHYs during surge coupling from powered cables. Use Value: Symmetrical VBR (66.7–73.7 V) and low capacitance (<100 pF typical) avoid signal distortion at 100BASE-TX/1000BASE-T speeds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60CA | Same VWM (60 V) and PPPM (1500 W), but SMA (DO-214AC) package - larger footprint, higher RθJA (85 °C/W) | Less suitable for space-constrained automotive modules; requires larger thermal pads | Choose SMAJ60CA only if DO-215AB footprint is unavailable or legacy board reuse is required |
| SMCJ60CA | Higher PPPM (3000 W), same VWM and DO-214AB package - physically larger, higher surge margin but lower power density | Better for industrial equipment with severe surge exposure (e.g., motor drives), not optimized for automotive weight/volume targets | Select SMCJ60CA when system-level testing demands >2000 W surge capability beyond ISO 7637-2 Class III |
Compared with SMAJ60CA and SMCJ60CA, the SMCG60CA-M3/9AT offers superior power density (1500 W in smallest DO-215AB outline), AEC-Q101 qualification out-of-box, and halogen-free compliance - making it the preferred choice for next-gen automotive and compact industrial designs where footprint, reliability, and regulatory alignment are critical.

FAQ
What does the "CA" suffix mean in SMCG60CA-M3/9AT?
The "CA" suffix denotes a bidirectional configuration - meaning the SMCG60CA-M3/9AT clamps voltage transients equally in both polarities, unlike unidirectional variants (e.g., SMCG60A). This eliminates polarity concerns during PCB layout and supports symmetric protection across differential lines or AC-coupled circuits without external diode pairing.
Is SMCG60CA-M3/9AT qualified for automotive use?
Yes, the SMCG60CA-M3/9AT is AEC-Q101 qualified per the Vishay datasheet (document 88457, revision 09-Jan-2024). This certification confirms its suitability for automotive applications including engine control units, ADAS sensors, and body electronics, with validated performance across -55 °C to +150 °C junction temperature and rigorous stress testing.
What is the significance of the "M3" suffix in SMCG60CA-M3/9AT?
The "M3" suffix indicates halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD 201 class 2 whisker resistance. For SMCG60CA-M3/9AT, this ensures environmental compliance for automotive and industrial markets while maintaining solderability per J-STD-002 and JESD 22-B102 standards.
How does SMCG60CA-M3/9AT compare to unidirectional SMCG60A in circuit implementation?
Unlike the unidirectional SMCG60A (which requires correct cathode orientation and only clamps negative transients), the SMCG60CA-M3/9AT has no polarity marking and clamps both positive and negative excursions symmetrically. This simplifies layout, eliminates reverse-installation risk, and enables single-device protection for AC signals or floating buses like CAN or LIN.
What PCB pad layout is recommended for optimal thermal performance of SMCG60CA-M3/9AT?
Vishay specifies a 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad for each terminal of the SMCG60CA-M3/9AT to achieve rated PPPM and thermal resistance (RθJA = 75 °C/W). Deviating from this layout reduces surge handling capability and increases junction temperature - especially critical in automotive under-hood applications where ambient temperatures exceed 85 °C.
