For engineers reviewing the SMCG7.0HE3/57T datasheet, SMCG7.0HE3/57T pinout, SMCG7.0HE3/57T application, or SMCG7.0HE3/57T equivalent, this page delivers verified electrical specs, package dimensions, clamping behavior under surge, AEC-Q101 qualification status, and direct alternatives for automotive-grade ESD/transient protection design.
Technical Context
The SMCG7.0HE3/57T is a bi-directional silicon avalanche diode operating symmetrically in both polarities, with breakdown voltage (VBR) of 7.78–8.60 V at 10 mA test current. Its low clamping ratio (VC/VWM ≈ 1.71) ensures effective overvoltage limiting during fast transients such as ISO 7637-2 pulses or ESD events.
Thermally, it exhibits RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = 150 °C. The device uses glass-passivated junction technology and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, supporting automated SMT assembly in high-reliability automotive PCBs.
Key Specifications

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-E3/57T | Uni-directional; VBR 7.78–8.60 V; same VC (12.0 V) but requires correct polarity placement. | Not suitable for AC-coupled or floating differential lines; limited to DC-biased unidirectional protection. | Select when circuit polarity is fixed and board space allows discrete cathode marking; avoid where bidirectional symmetry is required. |
| SMCJ7.0CA | Same DO-214AB package; higher PPPM (1500 W); identical VWM/VC but not AEC-Q101 qualified. | Lacks automotive qualification; intended for industrial/commercial use only - not approved for OEM automotive BOMs. | Use in non-automotive systems where cost is prioritized over qualification; verify lifecycle support and traceability separately. |
Compared with SMAJ7.0A-E3/57T and SMCJ7.0CA, the SMCG7.0HE3/57T uniquely combines bi-directional operation, AEC-Q101 qualification, and DO-215AB low-profile packaging - making it the only option among the three qualified for automotive sensor and infotainment module designs requiring zero-polarity-assembly and extended temperature reliability.

FAQ
What is the clamping voltage of SMCG7.0HE3/57T at its rated peak pulse current?
The SMCG7.0HE3/57T has a maximum clamping voltage (VC) of 12.0 V at 125 A peak pulse current (IPPM) using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and confirmed in the Vishay datasheet revision 14-Mar-12, ensuring predictable overvoltage limiting during surge events without exceeding protected IC voltage tolerances.
Is SMCG7.0HE3/57T suitable for automotive applications?
Yes, SMCG7.0HE3/57T is AEC-Q101 qualified and explicitly rated for automotive use. Its qualification includes high-temperature operating life (HTOL), temperature cycling, unbiased highly accelerated stress test (UHAST), and ESD testing per JESD22-A114. The HE3 suffix denotes AEC-Q101 compliance, making SMCG7.0HE3/57T appropriate for engine control units, ADAS sensors, and body electronics modules.
Does SMCG7.0HE3/57T have polarity markings?
No, SMCG7.0HE3/57T is a bi-directional TVS and carries no polarity marking on the package. As stated in the Vishay datasheet, "no marking on bi-directional types." This enables flexible placement across differential lines or AC-coupled signals without orientation constraints - unlike uni-directional variants such as SMCG7.0A which feature a cathode band.
What is the thermal resistance from junction to ambient for SMCG7.0HE3/57T?
The SMCG7.0HE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes standard JEDEC test conditions and is critical for calculating maximum power derating above TA = 25 °C, especially in enclosed automotive enclosures where ambient temperatures exceed 85 °C.
What does the 'HE3/57T' suffix mean in SMCG7.0HE3/57T?
The 'HE3' suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance; '57T' specifies packaging in 7-inch plastic tape-and-reel format with 850 units per reel.
