Product details
Overview
SMCG110-E3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) in DO-215AB (SMCG) package, designed for clamping voltage transients on signal/power lines. It features 110 V stand-off voltage (VWM), 177 A peak pulse current (IPPM) at 10/1000 µs, 177 V maximum clamping voltage (VC), 1500 W peak pulse power (PPPM), and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCG110-E3/57T datasheet, SMCG110-E3/57T pinout, SMCG110-E3/57T application, or SMCG110-E3/57T equivalent, key selection criteria include clamping performance under 10/1000 µs surge, bi-directional symmetry, thermal resistance (RθJA = 75 °C/W), RoHS compliance (E3 suffix), and MSL Level 1 moisture sensitivity rating.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) ranging from 122 V to 135 V at 1 mA test current. Its low incremental surge resistance enables effective energy diversion during ESD or lightning-induced transients without significant voltage overshoot.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers stable clamping up to TJ = 150 °C and meets J-STD-020 MSL Level 1 (260 °C peak reflow). The glass-passivated junction ensures long-term reliability under repetitive surge stress.
Key Specifications

|---|---|
| VWM | 110 V - Maximum continuous reverse operating voltage before clamping begins |
| IPPM (10/1000 µs) | 177 A - Peak surge current the device safely clamps without failure |
| VC | 177 V - Maximum voltage across terminals during IPPM surge, defining protection margin |
| PPPM | 1500 W - Peak transient power dissipation capability under standard waveform |
| TJ max. | +150 °C - Maximum junction temperature enabling operation in under-hood automotive environments |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient on recommended PCB pad layout |
| MSL Level | Level 1 - No floor life limitation; safe for standard reflow up to 260 °C peak |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110A-E3/57T | DO-214AC (SMA) package; lower PPPM (400 W); higher RθJA (110 °C/W) | Lower power handling limits use to ≤200 W surge environments; less suitable for automotive load dump | Select when board space allows larger footprint and surge energy is limited to IEC 61000-4-2 Level 4 only |
| SMCJ110CA-E3/57T | DO-214AB (SMC) package; same 1500 W PPPM but higher VC (187 V); non-AEC-Q101 | Larger body size (7.11 mm × 6.22 mm vs. 7.11 mm × 5.59 mm); lacks automotive qualification | Choose for industrial-only designs where AEC-Q101 is not mandated and 10 V higher clamping is acceptable |
Compared with SMAJ110A-E3/57T and SMCJ110CA-E3/57T, SMCG110-E3/57T uniquely combines AEC-Q101 qualification, DO-215AB's compact gull-wing form factor, and 177 V clamping at full 1500 W-enabling smaller, automotive-compliant layouts without sacrificing surge margin.

FAQ
What is the clamping voltage of SMCG110-E3/57T at its rated peak pulse current?
The SMCG110-E3/57T exhibits a maximum clamping voltage (VC) of 177 V when subjected to its rated 177 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured across the device terminals during surge testing and defines the upper voltage limit imposed on protected circuitry during transient events.
Is SMCG110-E3/57T suitable for automotive applications?
Yes, SMCG110-E3/57T is AEC-Q101 qualified and explicitly designed for automotive use. Its construction-including glass-passivated junction, MSL Level 1 rating, and operation up to +150 °C junction temperature-meets stringent reliability requirements for engine control, body electronics, and infotainment systems.
Does SMCG110-E3/57T have polarity markings?
No, SMCG110-E3/57T is a bi-directional TVS diode and carries no polarity marking. The DO-215AB package has symmetrical terminals with identical electrical behavior in both directions, eliminating the need for cathode band identification during placement.
What is the thermal resistance of SMCG110-E3/57T, and how does it affect layout?
The SMCG110-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This value assumes the recommended pad layout; reducing pad area increases thermal impedance and may require derating IPPM at elevated ambient temperatures.
What does the "E3/57T" suffix indicate in SMCG110-E3/57T?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "57T" specifies packaging in 7-inch plastic tape-and-reel format containing 850 units. This ordering code ensures traceable, standardized delivery compatible with high-volume SMT assembly lines.
