Product details
Overview
SMBG110AHE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of sensitive electronics. It features 110 V stand-off voltage (VWM), 122–135 V breakdown voltage (VBR) at 1 mA, 177 V maximum clamping voltage (VC) at 3.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the SMBG110AHE3/52 datasheet, SMBG110AHE3/52 pinout, SMBG110AHE3/52 application, or SMBG110AHE3/52 equivalent, key selection criteria include clamping performance under 3.4 A surge, AEC-Q101 qualification for automotive reliability, unidirectional polarity with cathode band marking, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a fast-acting shunt protector, triggering when reverse voltage exceeds its 122–135 V breakdown range to clamp transients to ≤177 V. Its glass-passivated junction ensures stable leakage (<1.0 µA at 110 V) and low incremental surge resistance, enabling consistent response across temperature (−55 °C to +150 °C).
Designed for unidirectional operation only, SMBG110AHE3/52 exhibits no bidirectional symmetry and requires correct cathode orientation during PCB layout. It meets J-STD-020 MSL Level 1 (260 °C peak reflow) and supports repetitive surge duty cycles up to 0.01 %, making it suitable for infrequent but high-energy transients like load dump or inductive switching spikes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - Maximum continuous reverse operating voltage before conduction begins; defines system working voltage margin. |
| VBR @ IT = 1 mA | 122–135 V - Breakdown threshold range; ensures reliable turn-on above normal operating voltage with controlled tolerance. |
| VC @ IPPM = 3.4 A | 177 V - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected downstream ICs. |
| PPPM | 600 W - Peak pulse power handling capability; validates survivability against standardized lightning/surge waveforms. |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports protection during short-circuit or fault events. |
| Junction Temp Range | −55 °C to +150 °C - Enables deployment in under-hood automotive and industrial environments without thermal derating. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by molded band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to ground or lower-potential rail in unidirectional TVS configuration. | Provides reference node for clamping action; must be routed with low-inductance path to minimize overshoot during surge. |
| Cathode | Current exit terminal in forward bias; marked by visible band; connected to protected line (e.g., 12 V supply or signal trace). | Determines polarity-sensitive placement; reversal prevents clamping and risks device failure under overvoltage. |

IC Role / Device Role / Timing Role: Localized TVS at motor driver output pins to absorb inductive energy during MOSFET turn-off. Use Value: Clamps 100 A surge peaks (8.3 ms) without failure, preserving gate driver IC integrity and preventing false triggering in closed-loop control. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A-E3/52 | Same VWM (110 V), slightly higher VC (187 V @ 3.2 A), identical SMB (DO-214AA) package footprint but 0.01 mm taller. | Lower peak pulse current rating (3.2 A vs. 3.4 A); less margin for worst-case ISO 7637-2 Pulse 5a. | Select when legacy SMB footprint is required and clamping voltage margin allows 10 V higher VC. |
| SMCJ110AHE3/52 | Same VWM/VBR, higher PPPM (1500 W), larger SMC (DO-214AB) package with 2.5× PCB area and 2× thermal mass. | Superior surge endurance for repeated high-energy events; not drop-in due to different pad layout and height. | Choose for industrial systems requiring >1000 surges or higher IPPM (7.5 A) where board space permits. |

FAQ
What is the clamping voltage of SMBG110AHE3/52 at its rated peak pulse current?
The SMBG110AHE3/52 has a maximum clamping voltage (VC) of 177 V at 3.4 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88456 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBG110AHE3/52 maintains this clamping performance across its full operating temperature range.
Is SMBG110AHE3/52 suitable for automotive applications?
Yes, SMBG110AHE3/52 is AEC-Q101 qualified and explicitly rated for automotive use per Vishay's documentation. Its construction includes glass-passivated junction, MSL Level 1 reflow compatibility, and operation from −55 °C to +150 °C - meeting requirements for engine control units, body electronics, and ADAS power domains. The SMBG110AHE3/52 carries the "HE3" suffix denoting AEC-Q101 qualification.
What does the "HE3/52" suffix indicate in SMBG110AHE3/52?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads; "52" specifies packaging in 7″ diameter plastic tape and reel with 750 units per reel. This ordering code aligns with Vishay's standardized nomenclature in document 88456 and confirms industrial-grade reliability and automated assembly readiness for the SMBG110AHE3/52.
How does SMBG110AHE3/52 differ from bidirectional TVS diodes like SMBG110CA?
SMBG110AHE3/52 is unidirectional and features a cathode band for polarity-sensitive placement, whereas SMBG110CA is bidirectional with no polarity marking and symmetric breakdown in both directions. The SMBG110AHE3/52 offers lower leakage (<1.0 µA at 110 V) and is intended for DC rail protection, while SMBG110CA suits AC-coupled or floating signal lines. They are not interchangeable without circuit review.
What is the thermal resistance of SMBG110AHE3/52, and how does it affect layout?
The SMBG110AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures during repetitive surges, PCB layout must replicate this minimum pad area and avoid excessive trace length or isolation. The SMBG110AHE3/52 thermal performance assumes no additional heatsinking.
