Product details
Overview
SMCG6.0-E3/9AT from Vishay General Semiconductor is a bi-directional surface-mount Transient Voltage Suppressor (TVS) in DO-215AB (SMCG) package, designed for clamping voltage transients on signal or power lines. It features 6.0 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), 10.3 V maximum clamping voltage (VC) at 145.6 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCG6.0-E3/9AT datasheet, SMCG6.0-E3/9AT pinout, SMCG6.0-E3/9AT application, or SMCG6.0-E3/9AT equivalent, key selection criteria include bi-directional clamping capability, low incremental surge resistance, MSL Level 1 moisture sensitivity, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions, with breakdown voltage (VBR) specified at 6.67–7.37 V under 10 mA test current. Its clamping behavior is defined by a 10/1000 μs waveform, delivering 145.6 A peak pulse current while limiting voltage to ≤10.3 V - critical for protecting downstream MOSFETs and ICs from inductive switching spikes.
Thermal performance is characterized by RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = 150 °C. The device meets J-STD-020 MSL Level 1 (260 °C peak reflow) and JESD 201 Class 1A whisker resistance, confirming suitability for high-reliability industrial and automotive PCB assemblies.

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-E3/57T | DO-214AC (SMA) package; 6.0 V VWM; 145 A IPPM; 10.3 V VC; same PPPM but higher RθJA (90 °C/W) | Larger footprint (4.5 mm × 2.7 mm vs. 7.87 mm × 10.16 mm); lower thermal mass limits repetitive surge duty cycle | Select when board space is constrained and thermal derating is acceptable |
| SMCJ6.0A-E3/9AT | DO-214AB (SMC) package; 6.0 V VWM; 150 A IPPM; 10.3 V VC; identical electrical specs but 2.5× higher RθJA (185 °C/W) | Same lead count but larger body (7.11 mm × 6.22 mm); requires larger copper pads for thermal management | Select when legacy SMC footprint compatibility is required and peak surge duration is <100 μs |
Compared with SMAJ6.0A-E3/57T and SMCJ6.0A-E3/9AT, SMCG6.0-E3/9AT offers superior thermal performance (RθJA = 75 °C/W) and optimized pad layout for high-energy transients - making it preferred for automotive and industrial applications demanding sustained surge resilience.

FAQ
What is the clamping voltage of SMCG6.0-E3/9AT at its rated peak pulse current?
The SMCG6.0-E3/9AT has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPPM) of 145.6 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuits during surge events - critical for ensuring compatibility with 5 V logic interfaces and preventing overvoltage damage to downstream ICs.
Is SMCG6.0-E3/9AT suitable for automotive applications?
Yes, SMCG6.0-E3/9AT is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass passivated junctions, MSL Level 1 reflow compatibility, and validated performance across -55 °C to +150 °C junction temperature range. The device is deployed in body control modules, infotainment power supplies, and sensor interfaces where protection against load dump and jump-start transients is required.
Does SMCG6.0-E3/9AT have polarity markings?
No, SMCG6.0-E3/9AT is a bi-directional TVS and carries no polarity marking on its DO-215AB (SMCG) package. The device functions identically regardless of orientation on the PCB, simplifying layout and eliminating risk of incorrect installation - a key advantage for differential signal lines, AC-coupled interfaces, or designs where voltage polarity reversal may occur.
What is the thermal resistance of SMCG6.0-E3/9AT, and how does it affect PCB layout?
SMCG6.0-E3/9AT 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 assumes minimum recommended pad layout per Vishay's datasheet; reducing pad area increases thermal impedance and risks exceeding TJ max. of 150 °C during repetitive surges - so adherence to the specified copper land pattern is essential for rated power handling.
How does the SMCG6.0-E3/9AT differ from the uni-directional SMCG6.0A variant?
The SMCG6.0-E3/9AT is the bi-directional version (denoted by "CA" suffix in base part numbering), whereas SMCG6.0A is uni-directional. Key differences include absence of cathode band marking, symmetrical VBR in both directions (6.67–7.37 V), and applicability to AC or polarity-agnostic circuits. Uni-directional variants include forward voltage (VF = 3.5 V at 100 A) and IFSM rating (200 A), which do not apply to SMCG6.0-E3/9AT.
