Product details
Overview
SMCJ6.0A-M3/9AT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 10.3 V maximum clamping voltage at 145.6 A peak pulse current, 6.0 V stand-off voltage, and 6.67–7.37 V breakdown voltage range at 10 mA test current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCJ6.0A-M3/9AT datasheet, SMCJ6.0A-M3/9AT pinout, SMCJ6.0A-M3/9AT application, or SMCJ6.0A-M3/9AT equivalent, key selection criteria include unidirectional polarity, 1500 W PPPM rating, 10.3 V VC at IPPM, -55 °C to +150 °C operating junction temperature, and halogen-free RoHS-compliant M3 suffix packaging for high-reliability board-level surge protection.
Technical Context
The SMCJ6.0A-M3/9AT operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response to ESD and lightning-induced transients. Its low incremental surge resistance and fast clamping action enable effective protection of downstream 5–6 V logic interfaces and power rails without sacrificing signal integrity.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it meets J-STD-020 MSL Level 1 (260 °C peak reflow), supports 200 A non-repetitive forward surge current (8.3 ms half-sine), and exhibits 0.059 %/°C temperature coefficient of VBR - critical for stable clamping across automotive thermal cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum reverse stand-off voltage before significant leakage; defines safe operating margin below breakdown for 5 V rail protection. |
| VBR min/max | 6.67 V / 7.37 V at 10 mA - Confirmed avalanche onset range; ensures reliable triggering within ±5% of nominal 6.0 V system voltage. |
| VC @ IPPM | 10.3 V - Clamped voltage during 145.6 A 10/1000 μs surge; limits stress on protected 6 V-rated components to <72% overvoltage. |
| PPPM | 1500 W - Peak pulse power handling per 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity design. |
| IPPM | 145.6 A - Peak surge current capability; enables robust protection against inductive switch-off spikes in motor drivers and power supplies. |
| TJ max | +150 °C - Maximum junction temperature; allows operation in under-hood automotive environments and high-power industrial enclosures. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; informs heatsinking requirements when operating near PD = 6.5 W continuous dissipation limit. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads. Cathode indicated by band marking on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path (unidirectional) | Connected to ground or low-side return; completes clamping path during positive transients on cathode-connected line. |
| Cathode | Protected line connection point | Connected to signal/power line requiring protection; avalanche conduction occurs from cathode to anode during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMC package | Enables automated placement and high-density PCB layouts while maintaining 1500 W surge capability in minimal footprint (7.75 mm × 6.22 mm). |
| Glass-passivated junction | Ensures long-term reliability and stable VBR performance under repeated surge stress and humid operating conditions. |
| MSL Level 1 rating | Supports single-reflow soldering at 260 °C peak without popcorn cracking or parameter shift - eliminates pre-bake requirement. |
| Halogen-free M3 suffix | Meets IPC-4101D/21 and JEDEC J-STD-020 environmental compliance for green manufacturing and end-of-life recycling. |
Applications
| Automotive Power Distribution | Industrial Sensor Interface Protection |

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 | Lower PPPM (400 W), smaller SMA package, same VWM/VC specs but reduced surge capacity. | Suitable for lower-energy ESD-only scenarios; insufficient for IEC 61000-4-5 surge testing. | Select SMAJ6.0A-M3 only where space constraints prohibit SMC and surge energy is limited to <400 W. |
| SMCJ6.0CA-M3 | Bidirectional variant with identical VWM, VBR, and PPPM, but symmetric clamping in both polarities. | Required for AC-coupled or floating signal lines (e.g., RS-485, Ethernet PHY) where negative transients occur. | Choose SMCJ6.0CA-M3 when protecting bidirectional data lines or ungrounded circuits; not interchangeable with unidirectional SMCJ6.0A-M3/9AT. |
Compared with SMAJ6.0A-M3 and SMCJ6.0CA-M3, the SMCJ6.0A-M3/9AT delivers 3.75× higher surge power handling than SMAJ6.0A-M3 while maintaining unidirectional polarity for optimized 5 V rail protection - making it the preferred choice for automotive and industrial DC power line hardening where 1500 W pulse absorption is mandatory.

FAQ
What is the maximum clamping voltage of the SMCJ6.0A-M3/9AT under a 10/1000 µs surge?
The SMCJ6.0A-M3/9AT has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current of 145.6 A using the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 09-Jan-2024, ensuring predictable overvoltage limiting for 5–6 V systems protected by the SMCJ6.0A-M3/9AT.
Is the SMCJ6.0A-M3/9AT RoHS-compliant and halogen-free?
Yes, the SMCJ6.0A-M3/9AT carries the M3 suffix, indicating it is both RoHS-compliant and halogen-free per IPC-4101D/21 and JEDEC J-STD-020 standards. The device uses matte tin-plated leads and UL 94 V-0 molding compound, satisfying environmental requirements for green manufacturing and end-of-life processing - a verified specification documented in Vishay's official ordering information table.
Does the SMCJ6.0A-M3/9AT meet AEC-Q101 qualification?
No, the SMCJ6.0A-M3/9AT is not AEC-Q101 qualified. Only variants with HE3 or HM3 suffixes (e.g., SMCJ6.0AHE3_A/I) carry AEC-Q101 qualification. The M3 suffix denotes commercial-grade, halogen-free, RoHS-compliant construction without automotive stress testing - confirmed in Vishay's mechanical data section and ordering information table.
What is the thermal resistance from junction to ambient for the SMCJ6.0A-M3/9AT?
The SMCJ6.0A-M3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the minimum recommended pad layout (0.31" × 0.31" copper pads). This value is specified in the Thermal Characteristics table of the Vishay datasheet and directly impacts derating calculations for continuous power dissipation in thermally constrained designs using the SMCJ6.0A-M3/9AT.
How does the SMCJ6.0A-M3/9AT differ from the SMCJ6.0CA-M3 variant?
The SMCJ6.0A-M3/9AT is unidirectional with cathode-band marking and clamps only positive transients relative to ground, whereas the SMCJ6.0CA-M3 is bidirectional with no polarity marking and clamps transients of either polarity. Their VWM, VBR, PPPM, and package are identical, but they are not functionally interchangeable - the SMCJ6.0A-M3/9AT must be oriented correctly in-circuit, unlike the SMCJ6.0CA-M3.
