Product details
Overview
SMCG7.0AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) in the SMCG (DO-215AB) package, featuring a 7.0 V stand-off voltage (VWM), 7.78–8.60 V breakdown voltage (VBR) at 10 mA, 125 A peak pulse current (IPPM), 12.0 V clamping voltage (VC) at IPPM, and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform. It is AEC-Q101 qualified and used for protecting MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial power electronics.
For engineers reviewing the SMCG7.0AHE3/57T datasheet, SMCG7.0AHE3/57T pinout, SMCG7.0AHE3/57T application, or SMCG7.0AHE3/57T equivalent, key selection criteria include unidirectional polarity, DO-215AB thermal performance (RθJA = 75 °C/W), 1500 W surge capability, AEC-Q101 qualification, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold, limiting transient energy to protected downstream circuitry. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<200 µA at VWM), while the low incremental surge resistance enables effective suppression of fast-rising ESD and load-dump events.
The SMCG7.0AHE3/57T is rated for -55 °C to +150 °C operating junction temperature, supports 200 A non-repetitive forward surge (IFSM), and meets J-STD-020 MSL Level 1 with 260 °C reflow peak. Its matte tin-plated leads comply with JESD 22-B102 whisker testing and J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 7.78 V / 8.60 V at 10 mA - Ensures reliable turn-on within tight tolerance for precise overvoltage protection |
| VC @ IPPM | 12.0 V at 125 A - Clamped voltage during 10/1000 µs surge, limiting stress on downstream ICs |
| PPPM | 1500 W - Peak transient power handling capacity under standardized surge waveform |
| IFSM | 200 A - Withstands single half-sine 8.3 ms surge, critical for automotive load-dump immunity |
| TJ max. | +150 °C - Enables operation in under-hood automotive environments and high-power industrial enclosures |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient on recommended 8 mm × 8 mm pad layout |
Pinout & Package
Package: SMCG (DO-215AB), surface-mount gull-wing leaded case with cathode band marking. Dimensions: 7.87 mm × 9.64 mm × 2.41 mm (L × W × H); lead pitch: 3.17 mm; weight: 0.211 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry (unidirectional) | Connected to ground or low-side return path; defines current direction during clamping |

Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock |
| Glass-passivated junction | Ensures stable VBR over lifetime and improved resistance to moisture-induced parameter drift |
| MSL Level 1 rating | Allows unlimited floor life and full 260 °C reflow compatibility without baking preconditioning |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes let-through voltage during surge, reducing risk of latch-up or gate oxide damage in protected MOSFETs |
| Matte tin plating | Enables robust solder joint formation per J-STD-002 and eliminates whisker-related field failures |
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 |
|---|---|---|---|
| SMAJ7.0A-E3/52T | Same VWM (7.0 V) and VC (12.0 V), but lower PPPM (400 W) and smaller SMA (DO-214AC) package | Limited to lower-energy transients; unsuitable for automotive load-dump or high-current motor drive protection | Select only where space constraints preclude DO-215AB and surge energy remains below 400 W |
| SMCJ7.0AHE3/57T | Identical VWM, VBR, VC, and PPPM (1500 W), but larger SMC (DO-214AB) package with higher RθJA (85 °C/W) | Requires larger PCB area and delivers lower thermal efficiency on same pad layout | Prefer SMCG7.0AHE3/57T when board space is constrained and thermal performance is critical |
Compared with SMAJ7.0A-E3/52T and SMCJ7.0AHE3/57T, the SMCG7.0AHE3/57T delivers identical electrical protection performance in a thermally superior, AEC-Q101 qualified DO-215AB package-enabling higher power density and automotive-grade reliability without layout compromise.

FAQ
What is the clamping voltage of SMCG7.0AHE3/57T and how is it measured?
The SMCG7.0AHE3/57T has a maximum clamping voltage (VC) of 12.0 V, measured at its rated peak pulse current (IPPM) of 125 A using a 10/1000 µs standard surge waveform. This value reflects the actual voltage seen by protected circuitry during worst-case transient events and is guaranteed across the full operating temperature range.
Is SMCG7.0AHE3/57T suitable for automotive applications?
Yes, SMCG7.0AHE3/57T is AEC-Q101 qualified and designed for automotive use, supporting critical requirements such as load-dump immunity (200 A IFSM), extended temperature operation (-55 °C to +150 °C), and MSL Level 1 reflow compatibility. Its HE3 suffix explicitly denotes AEC-Q101 qualification per Vishay's ordering nomenclature.
What does the "HE3" suffix mean in SMCG7.0AHE3/57T?
The "HE3" suffix in SMCG7.0AHE3/57T indicates RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's mechanical data, "HE3" denotes industrial-grade, halogen-free, RoHS-compliant devices certified to AEC-Q101 for automotive reliability-distinct from "E3" (RoHS only) and "HM3" (halogen-free + AEC-Q101).
How does the SMCG7.0AHE3/57T package compare thermally to SMA and SMC packages?
The SMCG7.0AHE3/57T uses the DO-215AB package with a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W on 8.0 mm × 8.0 mm copper pads-lower than SMA (DO-214AC, ~100 °C/W) and SMC (DO-214AB, ~85 °C/W). This enables higher sustained power dissipation and better thermal margin in compact layouts.
Can SMCG7.0AHE3/57T be used in bidirectional configurations?
No, SMCG7.0AHE3/57T is a unidirectional TVS diode, identified by the "A" (not "CA") suffix and marked with a cathode band. Bidirectional variants-such as SMCG7.0CA-exist in the same family but have different breakdown symmetry and no polarity marking; SMCG7.0AHE3/57T must be oriented correctly in-circuit with cathode toward the protected line.
