Product details
Overview
SMCG110HE3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) in DO-215AB (SMCG) package, designed for robust overvoltage protection on signal and power lines. It features a 110 V stand-off voltage (VWM), 177 A peak pulse current (IPPM) at 10/1000 µs, 1500 W peak pulse power (PPPM), clamping voltage of 177 V at IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCG110HE3/57T datasheet, SMCG110HE3/57T pinout, SMCG110HE3/57T application, or SMCG110HE3/57T equivalent, this device is selected for high-energy surge suppression in automotive ECUs, industrial sensor interfaces, and telecom line protection where low clamping ratio, fast response (<1 ns), and MSL Level 1 reliability are critical.
Technical Context
The SMCG110HE3/57T is a bi-directional silicon avalanche diode operating symmetrically in both polarities, with breakdown voltage (VBR) specified at 122–135 V (min/max) under 1 mA test current. Its clamping behavior follows standardized 10/1000 µs surge waveform compliance per ANSI/IEEE C62.35, and thermal performance is characterized by RθJA = 75 °C/W on 8.0 mm × 8.0 mm copper pads.
It exhibits <1 µA reverse leakage at VWM (110 V), operates across –55 °C to +150 °C junction temperature range, and maintains stable surge capability up to 1500 W due to glass-passivated junction and low incremental surge resistance - enabling reliable protection against inductive switching transients and ESD events without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 110 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 122–135 V at 1 mA - Ensures predictable, repeatable avalanche conduction onset during overvoltage events. |
| VC (Clamping Voltage) | 177 V at 177 A (10/1000 µs) - Limits downstream voltage stress to protect ICs like microcontrollers or CAN transceivers. |
| PPPM (Peak Pulse Power) | 1500 W - Sustains high-energy surges (e.g., ISO 7637-2 Pulse 5a) without failure when mounted per recommended pad layout. |
| ID (Reverse Leakage) | ≤1.0 µA at 110 V - Minimizes standby power loss and avoids false triggering in high-impedance circuits. |
| TJ max. | +150 °C - Supports under-hood automotive environments and industrial enclosures with elevated ambient temperatures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47. |
Pinout & Package
DO-215AB (SMCG) surface-mount package: low-profile gull-wing leads, matte tin-plated terminals solderable per J-STD-002/JESD22-B102, UL 94 V-0 molding compound, no polarity marking (bi-directional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | No functional distinction between terminals; either lead connects to protected line or ground - enables flexible PCB routing. |
| Lead 1 / Lead 2 | Current-carrying terminal | Both leads conduct surge current equally in either direction; requires equal copper area (8.0 mm × 8.0 mm) for thermal derating compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Protects AC-coupled or floating signal lines (e.g., RS-485, CAN FD differential pairs) without polarity constraints. |
| AEC-Q101 qualification | Validated for automotive electronics including engine control modules, ADAS sensors, and body control units. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns or baking requirements. |
| Glass-passivated junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity exposure. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., EFT bursts), improving protection margin for 3.3 V/5 V logic. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |

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 PPPM (400 W), but lower IPPM (36.1 A); SMA package (larger footprint, higher RθJA). | Limited to lower-energy transients (e.g., IEC 61000-4-2 only); unsuitable for ISO 7637-2 Pulse 5a. | Select when cost sensitivity outweighs surge energy requirement and board space permits larger package. |
| SMCJ110CA | Same VWM (110 V), higher PPPM (1500 W), identical DO-214AB package; slightly higher VC (187 V at 174 A). | Direct replacement in most layouts; marginally reduced clamping efficiency but same automotive qualification. | Choose if existing design uses SMCJ footprint and requires drop-in validation with minimal retest. |
Compared with SMAJ110CA and SMCJ110CA, the SMCG110HE3/57T delivers identical surge rating in a smaller DO-215AB footprint, tighter clamping (177 V vs. 187 V), and AEC-Q101 certification out-of-box - making it optimal for space-constrained automotive and industrial modules requiring highest protection density.

FAQ
What is the clamping voltage of the SMCG110HE3/57T under standard surge conditions?
The SMCG110HE3/57T has a maximum clamping voltage (VC) of 177 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 177 A. This value is measured per ANSI/IEEE C62.35 and ensures downstream components see limited overvoltage stress during surge events. The SMCG110HE3/57T achieves this with low incremental surge resistance and a tightly controlled avalanche junction.
Is the SMCG110HE3/57T suitable for automotive applications?
Yes, the SMCG110HE3/57T 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 temperature cycling, HTRB, and ESD testing make it appropriate for engine control units, ADAS camera modules, and body electronics. The SMCG110HE3/57T meets these requirements without derating.
How does the DO-215AB package of the SMCG110HE3/57T compare to DO-214AB in size and thermal performance?
The DO-215AB (SMCG) package is dimensionally smaller than DO-214AB, with tighter lead spacing and lower profile, yet maintains comparable thermal resistance: RθJA = 75 °C/W for SMCG110HE3/57T versus ~80 °C/W for typical DO-214AB parts. Both require 8.0 mm × 8.0 mm copper pads for full 1500 W rating. The SMCG110HE3/57T leverages optimized internal construction to achieve equivalent surge handling in reduced board area.
Does the SMCG110HE3/57T have polarity markings, and how is it installed on PCB?
No, the SMCG110HE3/57T is a bi-directional device and carries no polarity marking - there is no anode/cathode distinction. Either terminal may connect to the protected line or ground plane. Installation requires symmetric 8.0 mm × 8.0 mm copper pads per lead for thermal compliance, and no orientation alignment is needed during automated placement. This simplifies layout and reduces assembly errors compared to uni-directional TVS diodes.
What standards does the SMCG110HE3/57T meet for surge and ESD immunity?
The SMCG110HE3/57T meets IEC 61000-4-2 (ESD ±15 kV air/±8 kV contact), IEC 61000-4-4 (EFT ±2 kV), and IEC 61000-4-5 (surge 4 kV line-earth, 2 kV line-line) when applied per recommended layout. It also complies with ISO 7637-2 Pulse 5a (load dump) for automotive use. These capabilities are enabled by its 1500 W PPPM rating, sub-nanosecond response, and AEC-Q101 qualification - all verified for the SMCG110HE3/57T specifically.
