Product details
Overview
SMCG6.0A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in DO-215AB (SMCG) package, with 6.67 V to 7.37 V breakdown voltage at 10 mA, 6.0 V stand-off voltage, 10.3 V clamping voltage at 145.6 A peak pulse current, and 1500 W peak pulse power rating. It protects MOSFETs and ICs against inductive switching transients in automotive power electronics.
For engineers reviewing the SMCG6.0A-M3/57T datasheet, SMCG6.0A-M3/57T pinout, SMCG6.0A-M3/57T application, or SMCG6.0A-M3/57T equivalent, this device is selected for high-surge-capability, AEC-Q101-qualified TVS protection where low clamping voltage, halogen-free compliance, and MSL Level 1 reflow compatibility are required.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown above its specified VBR, providing low-impedance shunting of transient energy to ground. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while the DO-215AB package supports automated placement and meets UL 94 V-0 flammability.
Rated for -55 °C to +150 °C junction temperature, it delivers 1500 W peak pulse power under 10/1000 µs waveform with 10.3 V clamping at 145.6 A, and exhibits 75 °C/W junction-to-ambient thermal resistance on standard 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 6.0 V - maximum continuous reverse operating voltage before leakage exceeds 1000 µA |
| VC @ IPPM | 10.3 V at 145.6 A - clamping voltage during full 1500 W transient, limiting downstream stress |
| PPPM | 1500 W - peak surge power handling per 10/1000 µs waveform, critical for automotive load-dump immunity |
| IFSM | 200 A - non-repetitive forward surge rating (8.3 ms half-sine), supports unidirectional fault-current tolerance |
| TJ max. | +150 °C - enables operation in under-hood automotive environments without derating |
| MSL Level | Level 1 (260 °C peak) - allows standard lead-free reflow without moisture sensitivity concerns |
Pinout & Package
Package: DO-215AB (SMCG) - surface-mount gull-wing package with cathode band marking; 0.220"–0.245" body length, 0.115"–0.125" width, 0.024"–0.040" height; RoHS-compliant, halogen-free (M3 suffix), UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to protected line (e.g., 12 V rail); conducts during positive transients when cathode is grounded |
| Cathode | Avalanche reference / clamping node | Typically tied to system ground; establishes VBR reference and provides low-impedance sink for surge current |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
| Glass-passivated junction | Ensures stable VBR tolerance and <1000 µA leakage at VWM across temperature and life |
| Low incremental surge resistance | Enables tight VC/VBR ratio (1.54×), minimizing voltage overshoot during fast transients |
| Halogen-free (M3 suffix) | Meets IEC 61249-2-21 and JEDEC J-STD-20E environmental compliance for green manufacturing |
| MSL Level 1 rating | Eliminates bake requirements prior to SMT assembly, reducing production cost and risk of delamination |

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-M3/57T | DO-214AC (SMA) package; 75 W lower PPPM (1425 W); 10.5 V VC at 139 A | Lower surge margin; suitable for space-constrained consumer designs but not automotive load-dump duty cycles | Select SMAJ6.0A-M3/57T only if board area is critical and peak surge energy is ≤1425 W |
| SMCJ6.0A-M3/57T | DO-214AB (SMC) package; identical 1500 W PPPM and 10.3 V VC, but 2.5× higher RθJA (185 °C/W) | Requires larger thermal pad or forced cooling for sustained surge duty; less efficient heat dissipation than SMCG | Choose SMCJ6.0A-M3/57T only if existing layout uses SMC footprint and thermal management is enhanced |

The SMCG6.0A-M3/57T has a guaranteed breakdown voltage range of 6.67 V to 7.37 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight VBR window ensures consistent clamping behavior across production lots and temperature extremes, directly supporting design margin calculations for SMCG6.0A-M3/57T in 6 V nominal systems.
Is SMCG6.0A-M3/57T suitable for automotive applications?
Yes, SMCG6.0A-M3/57T is AEC-Q101 qualified and rated for -55 °C to +150 °C operation, making it suitable for under-hood and powertrain applications. Its 1500 W peak pulse power, 10.3 V clamping voltage, and MSL Level 1 reflow compatibility meet ISO 7637-2 and ISO 16750-2 requirements-key criteria for SMCG6.0A-M3/57T deployment in automotive ECUs and sensors.
What does the "M3" suffix indicate in SMCG6.0A-M3/57T?
The "M3" suffix in SMCG6.0A-M3/57T denotes halogen-free, RoHS-compliant construction meeting IEC 61249-2-21 and JEDEC J-STD-20E standards. It also confirms compliance with JESD 201 Class 2 whisker testing and matte tin-plated leads solderable per J-STD-002-critical for long-term reliability in SMCG6.0A-M3/57T industrial and automotive assemblies.
How does SMCG6.0A-M3/57T differ from bidirectional variants like SMCG6.0CA?
SMCG6.0A-M3/57T is unidirectional with cathode-band polarity and forward conduction capability, whereas SMCG6.0CA is bidirectional with symmetrical clamping in both directions and no polarity marking. The unidirectional SMCG6.0A-M3/57T offers lower leakage at VWM and supports DC-biased protection schemes, unlike SMCG6.0CA which is used in AC-coupled or floating-line applications.
What is the thermal resistance of SMCG6.0A-M3/57T?
The SMCG6.0A-M3/57T 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. This value is measured under standardized conditions and enables accurate thermal modeling for SMCG6.0A-M3/57T in high-power transient scenarios without forced cooling.
