Product details
Overview
SMCG110A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) in DO-215AB (SMCG) package, rated for 110 V standoff voltage (VWM), 122–135 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and 8.5 A peak pulse current (IPPM) at 10/1000 µs waveform. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics against inductive switching transients.
For engineers reviewing the SMCG110A-M3/57T datasheet, SMCG110A-M3/57T pinout, SMCG110A-M3/57T application, or SMCG110A-M3/57T equivalent, this device offers AEC-Q101 qualification, halogen-free RoHS compliance, MSL Level 1 rating, and verified clamping performance (VC = 177 V at IPPM) for robust overvoltage protection in high-reliability embedded systems.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable avalanche behavior and low incremental surge resistance. Its thermal resistance (RθJA = 75 °C/W) and junction temperature range (–55 to +150 °C) support operation on standard 8.0 mm × 8.0 mm copper pads without forced cooling.
The SMCG110A-M3/57T delivers fast response time (<1 ns), meets UL 497B recognition (QVGQ2), and maintains ≤1.0 µA reverse leakage at VWM - enabling reliable protection of 110 V DC bus interfaces and automotive power distribution networks where precise voltage thresholding and low standby loss are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 122 V / 135 V at 1.0 mA - guaranteed avalanche onset window for predictable turn-on margin |
| VC @ IPPM | 177 V at 8.5 A (10/1000 µs) - clamped voltage limiting downstream component stress during surge events |
| PPPM | 1500 W - peak transient energy absorption capability under standardized surge waveform |
| ID @ VWM | ≤1.0 µA - ultra-low leakage ensures minimal power loss in high-impedance 110 V monitoring circuits |
| TJ max. | +150 °C - enables use in under-hood automotive environments and sealed industrial enclosures |
| Package | DO-215AB (SMCG) - surface-mount gull-wing leadframe compatible with automated SMT placement and reflow |
Pinout & Package
Package: DO-215AB (SMCG), molded in UL 94 V-0 compliant compound, matte tin-plated leads, MSL Level 1, 260 °C peak reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to system ground or low-side reference | Provides return path during clamping; must be routed with low-inductance trace to minimize overshoot |
| Cathode | Current exit terminal in forward bias; marked by band; connects to protected line | Defines polarity-sensitive placement - incorrect orientation disables protection on 110 V supply rails |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and chassis applications requiring zero defect reliability over temperature cycling and vibration |
| Halogen-free & RoHS compliant (M3 suffix) | Meets IEC 61249-2-21 and JEDEC J-STD-20D for environmentally constrained production and end-of-life handling |
| Low incremental surge resistance | Enables tighter VC–VBR margin (ΔV = 55 V), reducing voltage overshoot during fast-rising transients in 48 V–110 V systems |
| Glass passivated chip junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in industrial control cabinets |
| MSL Level 1 rating | Allows indefinite floor life before reflow; eliminates bake-out requirement and supports just-in-time SMT assembly |

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 | Same VWM/VBR/PPPM but SMA (DO-214AC) package; RθJA = 85 °C/W vs. 75 °C/W; no AEC-Q101 qualification | Limited to industrial/commercial use; lower thermal performance reduces surge endurance at elevated ambient temperatures | Select when cost sensitivity outweighs automotive qualification and thermal margin requirements |
| SMCJ110A-M3/57T | Same VWM/VBR/PPPM but SMC (DO-214AB) package; higher IPPM (9.1 A); RθJA = 65 °C/W; AEC-Q101 qualified | Better thermal dissipation and surge current headroom; larger footprint requires PCB layout revision | Prefer for high-cycle-count applications like EV charging stations where long-term clamping stability is critical |
Compared with SMAJ110A-E3/57T, SMCG110A-M3/57T provides superior thermal management and automotive qualification; versus SMCJ110A-M3/57T, it trades 0.6 A IPPM and 10 °C/W higher RθJA for smaller DO-215AB footprint and identical halogen-free compliance.

FAQ
What is the clamping voltage of SMCG110A-M3/57T at its rated peak pulse current?
The SMCG110A-M3/57T has a maximum clamping voltage (VC) of 177 V when subjected to its specified peak pulse current (IPPM) of 8.5 A under the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events. The SMCG110A-M3/57T maintains this clamping performance across its qualified operating temperature range.
Is SMCG110A-M3/57T suitable for automotive applications?
Yes, SMCG110A-M3/57T is AEC-Q101 qualified and rated for operation from –55 °C to +150 °C, making it suitable for under-hood and powertrain-related automotive applications. Its halogen-free (M3) construction, UL 497B recognition, and validated surge endurance support use in ECU power inputs, body control modules, and ADAS sensor interfaces. The SMCG110A-M3/57T meets all stress test requirements defined in the AEC-Q101 standard.
What does the "M3" suffix indicate in SMCG110A-M3/57T?
The "M3" suffix in SMCG110A-M3/57T denotes halogen-free, RoHS-compliant construction meeting JEDEC J-STD-20D and IEC 61249-2-21 standards. It also signifies industrial-grade qualification with JESD201 Class 2 whisker resistance and MSL Level 1 moisture sensitivity. Unlike "E3" variants, SMCG110A-M3/57T contains no brominated flame retardants or chlorine-based compounds, supporting green manufacturing and end-of-life recycling requirements.
How does the DO-215AB package of SMCG110A-M3/57T compare thermally to DO-214AB (SMC)?
The DO-215AB (SMCG) package of SMCG110A-M3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W on 8.0 mm × 8.0 mm copper pads, versus ~65 °C/W for the larger DO-214AB (SMC) package. While SMCG110A-M3/57T offers a 25 % smaller footprint, its thermal performance is optimized for high-density layouts where board area is constrained but moderate surge duty cycles apply. The SMCG110A-M3/57T remains within safe TJ limits up to +125 °C ambient under full PPPM loading.
Can SMCG110A-M3/57T be used in bidirectional configurations?
No, SMCG110A-M3/57T is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional operation requires the "CA" suffix variant (e.g., SMCG110CA). Using SMCG110A-M3/57T in reverse-biased configurations will not provide symmetrical clamping and may result in catastrophic failure. For AC-coupled or dual-polarity signal lines, the SMCG110A-M3/57T must be paired with a second device or replaced with the correctly specified bidirectional part.
