Product details
Overview
SMCG6.0A-M3/9AT from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in DO-215AB (SMCG) package, with 6.0 V stand-off voltage, 6.67–7.37 V breakdown voltage at 10 mA, 1500 W peak pulse power (10/1000 µs), 145.6 A peak pulse current, and 10.3 V clamping voltage at IPPM. It protects MOSFETs and ICs against inductive switching transients in automotive power electronics.
For engineers reviewing the SMCG6.0A-M3/9AT datasheet, SMCG6.0A-M3/9AT pinout, SMCG6.0A-M3/9AT application, or SMCG6.0A-M3/9AT equivalent, key selection criteria include clamping voltage vs. protected device VDS(max), IFSM rating for surge robustness, halogen-free RoHS compliance (M3 suffix), AEC-Q101 qualification, and DO-215AB thermal performance under 8 mm × 8 mm pad layout.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds VBR (6.67–7.37 V), clamping transients to ≤10.3 V at 145.6 A. Its glass-passivated junction ensures stable breakdown and low leakage (<1000 µA at 6.0 V).
Designed for high-reliability automotive applications, it meets AEC-Q101 stress testing and MSL Level 1 (260 °C reflow). Thermal resistance is 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads, enabling sustained 6.5 W dissipation at TA = 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 6.67 V / 7.37 V at IT = 10 mA - defines reliable turn-on threshold across temperature and unit variation |
| VC at IPPM | 10.3 V at 145.6 A - clamping voltage during worst-case 10/1000 µs surge; must be below protected device's absolute max rating |
| PPPM | 1500 W - peak transient power handling capability under standardized waveform; determines surge energy absorption capacity |
| IFSM | 200 A - non-repetitive forward surge rating (8.3 ms half-sine); critical for load-dump or polarity-reversal immunity |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments |
| RθJA | 75 °C/W - thermal resistance on recommended 8 mm × 8 mm pads; used to calculate steady-state temperature rise |
Pinout & Package
Package: DO-215AB (SMCG) - low-profile, surface-mount gull-wing package with matte tin-plated leads, UL 94 V-0 molding compound, and cathode band marking for polarity identification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to ground or low-impedance return in unidirectional TVS configuration |
| Cathode | Transient voltage sensing node | Connected to line being protected; clamps to anode when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22 standards |
| Halogen-free & RoHS compliant (M3) | Meets environmental compliance requirements for Tier 1 automotive supply chains without compromising solderability or whisker resistance |
| Low incremental surge resistance | Enables tighter clamping (VC − VBR = 3.63 V) and faster energy diversion during fast transients |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning or baking |
| Glass passivated junction | Ensures long-term stability of VBR and low leakage drift over temperature and lifetime |
Applications
| Automotive Power Distribution | Industrial Motor Drive Inputs |
|---|---|

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-M3/8A | DO-214AC (SMA) package; lower PPPM (400 W); higher RθJA (110 °C/W) | Limited to lower-energy transients; less suitable for automotive load dump | Select SMAJ6.0A-M3/8A only where space constraints prohibit DO-215AB or surge energy is <400 W |
| SMCJ6.0A-M3/8A | DO-214AB (SMC) package; same 1500 W PPPM but larger footprint; 10.5 V VC at IPPM | Better thermal margin on large pads; slightly higher clamping voltage | Choose SMCJ6.0A-M3/8A when PCB layout allows larger SMC and margin above 10.3 V clamping is acceptable |
Compared with SMAJ6.0A-M3/8A and SMCJ6.0A-M3/8A, SMCG6.0A-M3/9AT delivers optimal balance of compact DO-215AB size, 1500 W surge capability, 10.3 V clamping, and AEC-Q101 qualification-making it the preferred choice for space-constrained, high-reliability automotive power nodes.

FAQ
What is the clamping voltage of SMCG6.0A-M3/9AT at its rated peak pulse current?
The SMCG6.0A-M3/9AT has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPPM) of 145.6 A under the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and verified on the standard 8.0 mm × 8.0 mm copper pad layout. The low VC ensures compatibility with 12 V system ICs having absolute maximum ratings above 10.3 V. SMCG6.0A-M3/9AT maintains this clamping performance across its full operating temperature range.
Is SMCG6.0A-M3/9AT qualified for automotive applications?
Yes, SMCG6.0A-M3/9AT is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per JESD22 standards. Its M3 suffix denotes halogen-free, RoHS-compliant construction meeting automotive material requirements. The device is rated for TJ = −55 °C to +150 °C and supports MSL Level 1 reflow. SMCG6.0A-M3/9AT is explicitly listed in Vishay's AEC-Q101 qualified product matrix for transient voltage suppressors.
What does the "M3" suffix indicate in SMCG6.0A-M3/9AT?
The "M3" suffix in SMCG6.0A-M3/9AT specifies halogen-free, RoHS-compliant construction with matte tin-plated leads that meet JESD201 Class 2 whisker resistance. It also confirms industrial-grade qualification and compliance with UL 94 V-0 flammability rating. Unlike "E3", M3 excludes brominated flame retardants and is required by many Tier 1 automotive OEMs. SMCG6.0A-M3/9AT's M3 designation is verified in Vishay's ordering information table and material categorization document 99912.
How does SMCG6.0A-M3/9AT differ from bidirectional variants like SMCG6.0CA?
SMCG6.0A-M3/9AT is unidirectional, with cathode marked by a band and intended for DC line protection where polarity is fixed. In contrast, SMCG6.0CA is bidirectional, lacks polarity marking, and provides symmetrical clamping in both directions-suitable for AC or differential signal lines. Electrical differences include SMCG6.0CA's doubled ID limit (2000 µA) for VWM ≤10 V and distinct marking codes (BDG vs. GDG). SMCG6.0A-M3/9AT's unidirectional design yields lower leakage and better clamping consistency in single-rail systems.
What is the thermal resistance of SMCG6.0A-M3/9AT, and how is it measured?
The SMCG6.0A-M3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W, measured on a 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad per terminal, per JEDEC standards. This value assumes no additional heatsinking and defines steady-state temperature rise under DC power dissipation. For example, at 6.5 W PD, junction temperature rises ~488 °C above ambient-hence derating is required above TA = 50 °C. SMCG6.0A-M3/9AT's RθJL is 15 °C/W, indicating efficient heat transfer to PCB traces.
