Product details
Overview
SMCG10CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for clamping voltage transients on signal or power lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), 88.2 A peak pulse current (IPPM), and clamps to ≤17.0 V at rated surge. It is AEC-Q101 qualified and used in automotive sensor line protection.
For engineers reviewing the SMCG10CA-E3/57T datasheet, SMCG10CA-E3/57T pinout, SMCG10CA-E3/57T application, or SMCG10CA-E3/57T equivalent, this page delivers verified electrical specs, bidirectional TVS behavior, DO-215AB mechanical data, AEC-Q101 qualification status, and real-world surge protection use cases - all confirmed from Vishay's official 88457 document (Rev. 09-Jan-2024).
Technical Context
The SMCG10CA-E3/57T operates as a bidirectional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 µA at VWM), while the low incremental surge resistance supports fast energy diversion during ESD or lightning-induced transients.
Thermally, it exhibits RθJA = 75 °C/W and RθJL = 15 °C/W, requiring defined copper pad layout (0.31" × 0.31") for full 1500 W rating. It meets J-STD-020 MSL Level 1 and is rated for TJ = –55 °C to +150 °C operation - critical for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping begins; defines safe signal swing range. |
| VBR (min/max) | 11.1 V / 12.3 V at IT = 1 mA - guaranteed avalanche onset window; ensures predictable turn-on across temperature and lot. |
| VC @ IPPM | ≤17.0 V at 88.2 A - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum stress level. |
| PPPM | 1500 W - peak transient power handling capability; enables robust protection against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | ≤1.0 µA - ultra-low reverse leakage at stand-off; preserves signal integrity in high-impedance sensor interfaces. |
| TJ max. | +150 °C - extended junction temperature rating; supports placement near heat sources in automotive ECUs. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including HTOL, TCT, and ESD testing per AEC standard. |

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 bidirectional structure, but lower PPPM (400 W) and smaller SMA (DO-214AC) package. | Limited to lower-energy transients (IEC 61000-4-2 only); unsuitable for IEC 61000-4-5 Level 3/4. | Select SMAJ10CA only when board space is constrained and surge threat level is limited to ESD-only environments. |
| SMCJ10CA | Same DO-214AB package footprint as SMCG but higher PPPM (1500 W), identical VWM/VBR, and same AEC-Q101 qualification. | Compatible with legacy SMCJ layouts; slightly larger body height may affect low-profile assemblies. | SMCJ10CA offers direct functional equivalence with identical surge rating - preferred where DO-214AB is already validated. |
Compared with SMAJ10CA and SMCJ10CA, the SMCG10CA-E3/57T delivers identical 1500 W surge capability and AEC-Q101 qualification in a lower-profile DO-215AB package, enabling tighter stacking height in modern automotive modules while maintaining full IEC 61000-4-5 compliance.

FAQ
What is the clamping voltage of SMCG10CA-E3/57T at its rated peak pulse current?
The SMCG10CA-E3/57T clamps to a maximum of 17.0 V at its rated peak pulse current (IPPM) of 88.2 A under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The clamping performance is consistent across both polarities due to its bidirectional construction.
Is SMCG10CA-E3/57T suitable for automotive applications?
Yes, SMCG10CA-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its –55 °C to +150 °C operating junction temperature range, MSL Level 1 reflow compatibility, and validation against HTOL, temperature cycling, and surge stress make it appropriate for engine control units, ADAS sensors, and body electronics where reliability is mission-critical.
Does SMCG10CA-E3/57T have polarity markings on the package?
No, SMCG10CA-E3/57T has no polarity markings because it is a bidirectional device. The SMCG (DO-215AB) package lacks a cathode band or other orientation indicators - both terminals are functionally identical. This simplifies PCB layout and eliminates orientation-related assembly errors in automated placement.
What is the maximum reverse leakage current for SMCG10CA-E3/57T at its stand-off voltage?
The maximum reverse leakage current (ID) for SMCG10CA-E3/57T is 1.0 µA at its 10 V stand-off voltage (VWM), measured at TA = 25 °C. This ultra-low leakage ensures minimal loading on high-impedance signal paths such as sensor bridges or analog front-ends, preserving measurement accuracy and reducing standby power loss.
How does the SMCG10CA-E3/57T package differ from the SMCJ series?
The SMCG10CA-E3/57T uses the DO-215AB package, which is dimensionally identical to DO-214AB (used by SMCJ) in length and width but features a lower profile (0.220"–0.245" height vs. ~0.265" for SMCJ). This reduced height supports tighter stacking in modern automotive modules while retaining the same 1500 W surge rating and AEC-Q101 qualification as SMCJ10CA.
