Product details
Overview
SMCG10-E3/57T from Vishay General Semiconductor is a bi-directional surface-mount Transient Voltage Suppressor (TVS) in DO-215AB (SMCG) package, designed for clamping voltage transients on signal and power lines. It features 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 88.2 A peak pulse current (IPPM), 1500 W peak pulse power (PPPM), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG10-E3/57T datasheet, SMCG10-E3/57T pinout, SMCG10-E3/57T application, or SMCG10-E3/57T equivalent, key selection criteria include bi-directional clamping capability, low incremental surge resistance, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCG10-E3/57T operates as a bi-directional avalanche diode, exhibiting symmetrical breakdown behavior in both polarities with minimum breakdown voltage (VBR) of 11.1 V and maximum of 12.3 V at 1.0 mA test current. Its glass-passivated junction ensures stable leakage performance and fast response to transients under 10/1000 μs waveform conditions.
Thermal design is constrained by RθJA = 75 °C/W and RθJL = 15 °C/W, requiring careful PCB pad layout per Vishay's recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper areas. The device sustains operation from –55 °C to +150 °C junction temperature and meets UL 94 V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse voltage before clamping begins; defines operating margin for protected circuitry. |
| VC (Clamping Voltage) | 17.0 V at IPPM - Peak voltage seen across device during 10/1000 μs transient; limits stress on downstream ICs. |
| IPPM (Peak Pulse Current) | 88.2 A - Maximum non-repetitive surge current it can safely divert without degradation. |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capacity for standardized 10/1000 μs surge; determines robustness against lightning/ESD events. |
| ID (Reverse Leakage) | 5.0 μA at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | +150 °C - Enables use in under-hood automotive environments and industrial enclosures without derating. |
| MSL Level | Level 1 (per J-STD-020) - Supports standard reflow profiles up to 260 °C peak without baking requirement. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/57T | DO-214AC (SMA) package; 10 V VWM, 18.2 V VC at 69.4 A IPPM; lower PPPM (400 W). | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a where SMCG10-E3/57T's 1500 W is required. | Select SMAJ10A-E3/57T only when board space is constrained and surge energy remains below 400 W capability. |
| SMCJ10CA-E3/57T | DO-214AB (SMC) package; identical 10 V VWM and 17.0 V VC, but higher IPPM (102 A) and PPPM (1500 W); larger footprint. | Higher thermal mass supports longer surge durations; requires larger PCB pad area (≥10 mm² per terminal). | Choose SMCJ10CA-E3/57T when system-level testing demands extended surge duration margin beyond DO-215AB limits. |
Compared with SMAJ10A-E3/57T and SMCJ10CA-E3/57T, the SMCG10-E3/57T delivers optimal balance of high-energy surge handling (1500 W), compact DO-215AB footprint, and AEC-Q101 qualification-making it preferred for space-constrained automotive and industrial modules where both reliability and board area efficiency are critical.

FAQ
What is the clamping voltage of SMCG10-E3/57T and how is it measured?
The SMCG10-E3/57T has a maximum clamping voltage (VC) of 17.0 V, measured at its rated peak pulse current (IPPM) of 88.2 A under a standardized 10/1000 μs double-exponential surge waveform. This value is guaranteed per Vishay's datasheet Document Number 88457 and reflects worst-case voltage seen across the device during transient suppression-critical for ensuring downstream ICs remain within safe operating limits. The SMCG10-E3/57T achieves this with low incremental surge resistance inherent to its glass-passivated junction structure.
Is SMCG10-E3/57T suitable for automotive applications?
Yes, SMCG10-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control, body electronics, and ADAS sensor interfaces. Its operating junction temperature range of –55 °C to +150 °C, MSL Level 1 reflow compatibility, and validation against ISO 7637-2 load-dump and pulse test profiles confirm suitability. The SMCG10-E3/57T also meets UL 94 V-0 flammability requirements for under-hood modules.
How does the DO-215AB package of SMCG10-E3/57T compare to DO-214AB (SMC) in thermal performance?
The DO-215AB (SMCG) package of SMCG10-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W, versus ~50–55 °C/W for DO-214AB (SMC). This means the SMCG10-E3/57T requires stricter adherence to Vishay's recommended 8.0 mm × 8.0 mm copper pad layout to achieve full 1500 W rating. While smaller in footprint, the SMCG10-E3/57T trades some thermal headroom for board-area savings-making it ideal where space is constrained but surge energy remains within its validated capability.
Does SMCG10-E3/57T have polarity markings, and how is it mounted?
No, SMCG10-E3/57T is a bi-directional TVS and carries no polarity marking-its terminals are functionally identical and interchangeable. Mounting uses standard gull-wing SMT reflow per J-STD-020 MSL Level 1, with matte tin-plated leads compatible with J-STD-002 solderability requirements. The SMCG10-E3/57T must be placed on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to maintain thermal and surge performance per datasheet Fig. 2 and Table "Maximum Ratings".
What is the reverse leakage current specification for SMCG10-E3/57T at its stand-off voltage?
The SMCG10-E3/57T exhibits a maximum reverse leakage current (ID) of 5.0 μA at its 10 V stand-off voltage (VWM), measured at TA = 25 °C. This low leakage ensures minimal loading on high-impedance signal paths such as sensor outputs or communication bus lines, preserving accuracy and noise margins. The SMCG10-E3/57T maintains this spec across its full operating temperature range, supported by its glass-passivated chip junction construction.
