Product details
Overview
SMCG10AHE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, featuring a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 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-level surge protection on power rails and signal lines.
For engineers reviewing the SMCG10AHE3/57T datasheet, SMCG10AHE3/57T pinout, SMCG10AHE3/57T application, or SMCG10AHE3/57T equivalent, key selection criteria include clamping performance under 10/1000 µs transients, junction temperature derating above 25 °C, unidirectional polarity marking, and compliance with UL 497B and AEC-Q101 for automotive electronics.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients. Its bidirectional counterpart (e.g., SMCG10CA) shares identical VWM and VBR ranges but differs in polarity configuration and marking.
The device operates within -55 °C to +150 °C junction temperature range and exhibits 75 °C/W typical thermal resistance (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads. It meets JESD201 Class 2 whisker resistance and is rated for MSL Level 1 per J-STD-020 at 260 °C peak reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC rail margin. |
| VBR (min/max) | 11.1 V / 12.3 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on threshold. |
| VC @ IPPM | 17.0 V at 88.2 A - Clamped voltage during 10/1000 µs surge; determines protected circuit's maximum overvoltage exposure. |
| PPPM | 1500 W - Peak transient power it can absorb without failure; validates robustness against IEC 61000-4-5 Level 4 surges. |
| TJ max. | +150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive environments. |
| RθJA | 75 °C/W - Thermal resistance on standard PCB pad layout; informs heatsinking requirements for sustained surge duty. |
| AEC-Q101 | Qualified - Certified for automotive-grade reliability including HTOL, TC, and ESD testing per stress test plan. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, low-profile gull-wing leaded case with matte tin-plated terminals, UL 94 V-0 molding compound, and cathode band marking for unidirectional polarity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/57T | Same VWM (10 V), lower PPPM (400 W), SMA (DO-214AC) package, higher RθJA (110 °C/W). | Lower surge capacity; suitable only for non-automotive, low-energy I/O lines. | Select when cost or board space is prioritized over automotive qualification and high-power surge handling. |
| SMCJ10AHE3/57T | Same VWM (10 V), higher PPPM (1500 W), identical AEC-Q101 qualification, but SMC (DO-214AB) package with larger footprint. | Higher thermal mass enables better sustained surge dissipation; requires larger PCB area. | Choose when enhanced thermal performance is needed beyond SMCG's 75 °C/W, especially in high-ambient environments. |
Compared with SMAJ10A-E3/57T, SMCG10AHE3/57T delivers 3.75× higher surge power and automotive qualification; versus SMCJ10AHE3/57T, it offers identical electrical specs in a 30% smaller footprint but with slightly reduced thermal margin due to smaller copper pad area.

FAQ
What is the clamping voltage of SMCG10AHE3/57T at its rated peak pulse current?
The SMCG10AHE3/57T has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated 88.2 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured at the device terminals with specified PCB pad layout (8.0 mm × 8.0 mm copper), and represents the upper limit of voltage imposed on the protected circuit during surge events. The SMCG10AHE3/57T maintains this clamping performance across its full operating temperature range.
Is SMCG10AHE3/57T suitable for automotive applications?
Yes, SMCG10AHE3/57T is explicitly AEC-Q101 qualified and manufactured with HE3 suffix denoting AEC-Q101 qualification, RoHS compliance, and industrial grade reliability. It is validated for use in automotive subsystems including body control modules, infotainment power supplies, and ADAS sensor interfaces where load dump, jump start, and ESD immunity are required. The SMCG10AHE3/57T meets UL 497B recognition and operates up to +150 °C junction temperature.
What does the "HE3/57T" suffix indicate in SMCG10AHE3/57T?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads meeting JESD201 Class 2 whisker resistance. The "57T" indicates packaging in 7-inch diameter plastic tape and reel, with a base quantity of 850 units per reel. This ordering code ensures traceable, automotive-grade material flow and surface-mount compatibility with standard pick-and-place equipment.
How does SMCG10AHE3/57T differ from bidirectional variants like SMCG10CA?
SMCG10AHE3/57T is unidirectional, with a cathode band marking and forward conduction capability; SMCG10CA is bidirectional, lacking polarity marking and symmetric clamping in both directions. Electrically, both share identical VWM (10 V) and VBR (11.1–12.3 V), but SMCG10AHE3/57T supports forward surge current (IFSM = 200 A), whereas SMCG10CA does not. The SMCG10AHE3/57T is used where polarity is known and ground-referenced clamping is preferred.
What is the thermal resistance of SMCG10AHE3/57T, and how does it affect layout design?
The SMCG10AHE3/57T 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 no additional heatsinking; reducing pad size or omitting thermal vias increases RθJA, risking junction overheating during repeated surges. For reliable operation in high-ambient environments, designers should maintain minimum pad dimensions and consider thermal vias to inner ground planes-critical for sustaining SMCG10AHE3/57T performance in automotive under-hood applications.
