Product details
Overview
SMCG6.0-E3/57T from Vishay General Semiconductor is a bi-directional surface-mount Transient Voltage Suppressor (TVS) in DO-215AB (SMCG) package, rated for 6.0 V stand-off voltage, 1500 W peak pulse power, and clamping at 10.3 V under 145.6 A surge current. It protects signal lines in automotive sensor units and industrial control interfaces against inductive switching transients.
For engineers reviewing the SMCG6.0-E3/57T datasheet, SMCG6.0-E3/57T pinout, SMCG6.0-E3/57T application, or SMCG6.0-E3/57T equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), DO-215AB mechanical dimensions, and real-world protection use cases - all confirmed from Vishay Document #88457.
Technical Context
This bi-directional TVS operates symmetrically across both polarities with identical breakdown (6.67–7.37 V), clamping (10.3 V), and leakage (<1000 µA at 6.0 V) characteristics in either direction. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for protecting MOSFET gates and microcontroller I/O pins.
Designed for surface-mount reflow assembly, it meets J-STD-020 MSL Level 1 (260 °C peak), JESD201 Class 1A whisker resistance, and UL 94 V-0 flammability. The device is not polarity-marked - consistent with bi-directional construction per Vishay specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse stand-off voltage before conduction begins; sets protection threshold for 5 V logic and CAN bus interfaces. |
| VC @ IPPM | 10.3 V - Clamped voltage during 145.6 A, 10/1000 µs surge; ensures downstream ICs remain below absolute maximum ratings. |
| PPPM | 1500 W - Peak pulse power handling capability; supports high-energy transients from relay coils or motor drivers. |
| IPPM | 145.6 A - Peak surge current capacity at 10/1000 µs waveform; validated on 8.0 mm × 8.0 mm copper pads per test condition. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; defines derating above 25 °C ambient for sustained power dissipation. |
| TJ max | +150 °C - Maximum operating junction temperature; enables use in under-hood automotive environments. |
| AEC-Q101 | Qualified - Certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan. |
Pinout & Package
DO-215AB (SMCG) package: gull-wing surface-mount outline with two terminals, no polarity marking (bi-directional). Dimensions: 7.87 mm × 3.17 mm × 2.41 mm (L × W × H); lead pitch 2.54 mm; matte tin-plated leads solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional transient conduction path | No functional distinction between terminals; connects across protected line and ground (or rail) without orientation constraint. |
| Case / Body | Non-electrical mechanical interface | UL 94 V-0 molded compound provides flame retardancy and mechanical stability during reflow and vibration. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional suppression | Identical VBR, VC, and IPPM in both directions - eliminates polarity concerns in AC-coupled or differential signal paths like RS-485 or CAN. |
| Glass-passivated junction | Enables <1 ns response time and stable leakage (<1000 µA) over lifetime - critical for low-power sensor nodes where standby current matters. |
| MSL Level 1 rating | Compatible with standard SMT reflow profiles up to 260 °C peak - no moisture sensitivity handling required before assembly. |
| AEC-Q101 qualification | Validated for automotive under-hood applications including temperature cycling (-55 °C to +150 °C) and high-acceleration mechanical shock. |
| Low Rsurge | Minimizes voltage overshoot during fast transients - measured clamping at 10.3 V ensures robust protection of 3.3 V and 5 V logic rails. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O 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-E3/57T | Uni-directional; 6.0 V VWM, 10.3 V VC, same PPPM but requires correct polarity placement. | Only suitable where circuit topology enforces unidirectional bias (e.g., DC power rail protection). | Select only if polarity is fixed and board layout allows cathode orientation alignment. |
| SMCJ6.0A-E3/57T | Higher PPPM (1500 W same), but larger DO-214AB package (7.11 mm × 6.22 mm); VC = 10.3 V identical. | Better thermal dissipation (RθJA ≈ 50 °C/W), but occupies ~2.5× PCB area - unsuitable for space-constrained modules. | Prefer when sustained surge duty cycle exceeds 1 Hz or ambient exceeds 85 °C. |
Compared with SMAJ6.0A-E3/57T and SMCJ6.0A-E3/57T, the SMCG6.0-E3/57T offers bi-directional symmetry in the smallest footprint (DO-215AB), making it optimal for differential signaling and compact automotive ECUs where polarity independence and board space are critical.

FAQ
What is the polarity configuration of SMCG6.0-E3/57T?
The SMCG6.0-E3/57T is a bi-directional TVS diode with no polarity marking on the DO-215AB package. Its symmetrical construction means either terminal may connect to the protected line or ground - ideal for AC-coupled or differential signals where polarity reversal is possible. This eliminates orientation errors during automated placement.
Does SMCG6.0-E3/57T meet AEC-Q101 requirements?
Yes, SMCG6.0-E3/57T is AEC-Q101 qualified (as confirmed in Vishay Document #88457, page 1). It undergoes full stress testing including temperature cycling, high-temperature reverse bias, and ESD per the AEC-Q101-004 standard - making it suitable for automotive under-hood and chassis applications.
What is the clamping voltage of SMCG6.0-E3/57T at its rated surge current?
The SMCG6.0-E3/57T clamps to 10.3 V when subjected to its peak pulse current (IPPM) of 145.6 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions on 8.0 mm × 8.0 mm copper pads and ensures downstream 5 V logic remains within safe operating limits.
Can SMCG6.0-E3/57T be used in place of a uni-directional TVS like SMAJ6.0A?
SMCG6.0-E3/57T can replace SMAJ6.0A only in circuits where polarity is undefined or bidirectional - such as RS-485 bus lines or AC-coupled audio paths. In DC rail protection, SMAJ6.0A's unidirectional behavior may offer tighter leakage control; substituting SMCG6.0-E3/57T there introduces no harm but forfeits the cathode-directed optimization.
What is the thermal resistance of SMCG6.0-E3/57T, and how does it affect layout?
SMCG6.0-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended pads. To maintain reliability at elevated ambient temperatures, PCB layout must include ≥8.0 mm × 8.0 mm copper pads per terminal - matching the test condition used to validate its 1500 W surge rating.
