Overview
SMCG110CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection of signal and power lines. It features a 110 V stand-off voltage (VWM), 122–135 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), clamping voltage of 177 V at 8.5 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCG110CA-E3/57T datasheet, SMCG110CA-E3/57T pinout, SMCG110CA-E3/57T application, or SMCG110CA-E3/57T equivalent, this device is selected for high-energy surge suppression in automotive sensor interfaces, industrial I/O ports, and telecom line protection where bidirectional clamping, low leakage (<1 µA at VWM), and MSL Level 1 reflow compatibility are critical.
Technical Context
The SMCG110CA-E3/57T operates as a bidirectional avalanche diode with symmetrical clamping behavior in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
Designed for surface-mount assembly on standard PCB pads (8.0 mm × 8.0 mm copper), it delivers 1500 W peak pulse power handling with a thermal resistance of 75 °C/W (junction-to-ambient) and supports operating junction temperatures up to +150 °C - making it suitable for under-hood automotive environments and industrial control cabinets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 110 V - Maximum continuous reverse voltage before significant conduction; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 122–135 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 177 V at 8.5 A IPPM - Peak voltage seen by protected circuit during 10/1000 µs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 1500 W - Sustains high-energy transients (e.g., ISO 7637-2 Pulse 1/2a/5a) without failure when mounted per recommended pad layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110CA | Same VWM (110 V) and bidirectional configuration, but lower PPPM (400 W) and higher VC (183 V at 5.5 A); SMA (DO-214AC) package. | Limited to lower-energy transients (e.g., ESD, contact discharge); unsuitable for ISO 7637-2 Pulse 5a. | Select SMAJ110CA only for cost-sensitive consumer applications with modest surge requirements and space-constrained layouts. |
| SMCJ110CA | Identical electrical specs (110 V VWM, 1500 W PPPM, 177 V VC), but larger SMC (DO-214AB) package with higher thermal mass and RθJA ≈ 40 °C/W. | Better thermal performance in high-ambient or high-duty-cycle surge environments; requires larger PCB footprint. | Choose SMCJ110CA when sustained surge repetition or ambient >105 °C demands superior heat dissipation over compactness. |

This value reflects the actual voltage imposed on the protected circuit during surge events and is guaranteed per Vishay's datasheet test conditions with 8.0 mm × 8.0 mm copper pads.
Is the SMCG110CA-E3/57T suitable for automotive applications?
Yes, the SMCG110CA-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its construction - glass-passivated junction, MSL Level 1 reflow compatibility, and operation up to +150 °C - meets stringent automotive reliability and manufacturing requirements.
Does the SMCG110CA-E3/57T have polarity markings on the package?
No, the SMCG110CA-E3/57T is a bidirectional TVS diode and carries no polarity marking on the SMCG (DO-215AB) package. Its symmetrical structure allows installation in either orientation, eliminating risk of incorrect placement during automated assembly and simplifying layout for differential or floating signal lines.
What is the maximum reverse leakage current for SMCG110CA-E3/57T at its stand-off voltage?
The SMCG110CA-E3/57T exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 110 V stand-off voltage (VWM), tested at TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor circuits and avoids loading effects on precision analog or communication lines.
How does the SMCG110CA-E3/57T compare to unidirectional variants like SMCG110A-E3/57T?
The SMCG110CA-E3/57T differs from SMCG110A-E3/57T solely in polarity: "CA" denotes bidirectional operation with symmetrical clamping, while "A" indicates unidirectional function with cathode band marking.
