Product details
Overview
SMCG10HE3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) in DO-215AB (SMCG) package, rated for 10 V stand-off voltage (VWM), 17.0 V clamping voltage (VC) at 88.2 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM). It is AEC-Q101 qualified and designed for automotive-grade surge protection on signal lines and power rails.
For engineers reviewing the SMCG10HE3/57T datasheet, SMCG10HE3/57T pinout, SMCG10HE3/57T application, or SMCG10HE3/57T equivalent, key selection criteria include bi-directional clamping capability, 1500 W surge rating, DO-215AB thermal performance (RθJA = 75 °C/W), AEC-Q101 qualification, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) of 11.1–12.3 V at 1.0 mA test current and maximum reverse leakage (ID) ≤ 5.0 μA at 10 V stand-off. Its low clamping ratio (VC/VWM ≈ 1.7) ensures effective overvoltage limiting during transients such as ISO 7637-2 load dump or ESD events.
Thermally, it features RθJL = 15 °C/W junction-to-lead resistance and supports continuous power dissipation of 6.5 W at TA = 50 °C. The device uses glass-passivated silicon junctions and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance.
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 |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V) and bi-directional function, but lower PPPM (400 W) and larger SMA package (DO-214AC) | Limited to lower-energy transients; unsuitable for automotive load dump | Select SMAJ10CA only for cost-sensitive consumer applications with <400 W surge exposure |
| 1.5KE10CA | Higher PPPM (1500 W), through-hole DO-204AB package, higher RθJA (~100 °C/W) | Requires PCB real estate and wave-solder process; less suitable for high-density SMT designs | Choose 1.5KE10CA where board space allows and reflow compatibility is not required |
Compared with SMAJ10CA and 1.5KE10CA, SMCG10HE3/57T delivers identical 10 V bi-directional clamping with full 1500 W surge capacity in a compact, AEC-Q101-qualified surface-mount package optimized for automotive and high-reliability SMT assembly.

FAQ
What is the clamping voltage of SMCG10HE3/57T under a 10/1000 µs surge?
The SMCG10HE3/57T clamps to a maximum of 17.0 V when subjected to its rated peak pulse current of 88.2 A under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 14-Mar-12, ensuring predictable overvoltage limiting for protected circuitry.
Is SMCG10HE3/57T suitable for automotive applications?
Yes, SMCG10HE3/57T is AEC-Q101 qualified and explicitly designed for automotive use. Its construction includes glass-passivated junctions, MSL Level 1 moisture sensitivity rating, and validated performance across -55 °C to +150 °C junction temperature range - all critical for under-hood and body-control module deployments.
Does SMCG10HE3/57T have polarity markings on the package?
No, SMCG10HE3/57T is a bi-directional TVS device and carries no polarity marking on the DO-215AB (SMCG) package. The device functions identically regardless of orientation, making it ideal for protecting AC-coupled or floating signal paths without layout constraints.
What is the thermal resistance of SMCG10HE3/57T to ambient air?
The SMCG10HE3/57T 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 still-air conditions and is essential for calculating safe power derating above TA = 25 °C.
How does SMCG10HE3/57T differ from uni-directional variants like SMCG10A?
SMCG10HE3/57T is bi-directional (suffix "CA") with symmetrical clamping in both polarities and no cathode band, whereas SMCG10A is uni-directional with a marked cathode end and forward voltage drop (VF = 3.5 V at 100 A). The bi-directional version is used where voltage transients may swing positive or negative relative to ground.
