Product details
Overview
SMBG6.0A-M3/52 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 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 10.3 V maximum clamping voltage (VC) at 58.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed on automotive sensor signal lines, industrial I/O ports, and DC power rails.
For engineers reviewing the SMBG6.0A-M3/52 datasheet, SMBG6.0A-M3/52 pinout, SMBG6.0A-M3/52 application, or SMBG6.0A-M3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, halogen-free RoHS compliance (M3 suffix), 150 °C max junction temperature, 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 clamp during voltage transients, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its unidirectional configuration enables integration into DC-biased circuits where reverse conduction must be blocked - such as 5 V or 12 V supply rails feeding microcontrollers or CAN transceivers.
The device meets J-STD-020 MSL Level 1 moisture sensitivity and withstands 100 A non-repetitive forward surge (8.3 ms half-sine), making it suitable for inductive load switching events in automotive body control modules and industrial PLC inputs. Thermal resistance is specified at RθJA = 100 °C/W (on 0.2" × 0.2" pads) and RθJL = 20 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets upper limit for normal circuit operation. |
| VBR @ IT = 10 mA | 6.67–7.37 V - Breakdown threshold range; ensures reliable triggering above nominal rail while avoiding false trips. |
| VC @ IPPM = 58.3 A | 10.3 V - Clamped voltage during 600 W transient; defines worst-case stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; supports common ISO 7637-2 and IEC 61000-4-5 surge profiles. |
| IFSM | 100 A - Single half-sine surge rating (8.3 ms); validates survivability against motor or relay coil turn-off spikes. |
| Junction Temp Range | –55 °C to +150 °C - Enables deployment in under-hood automotive and high-temperature industrial enclosures. |
| Package | SMBG (DO-215AA) - Surface-mount outline with 0.235–0.255" length; optimized for high-density PCB layouts and reflow compatibility. |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, gull-wing leads, matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band marking; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line (e.g., signal or supply); conducts surge current to ground when VWM exceeded. |
| Anode (unbanded end) | Reference / return path | Typically tied to system ground or lowest potential node; completes clamping path during overvoltage event. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces per stress test requirements. |
| Halogen-free & RoHS compliant (M3 suffix) | Meets environmental compliance mandates for industrial and automotive OEMs without compromising thermal or electrical performance. |
| 600 W peak pulse power (10/1000 μs) | Provides robust protection against common ESD, lightning-induced surges, and inductive switching transients in harsh environments. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during clamping, reducing risk of latch-up or damage to downstream 5 V logic devices. |
| MSL Level 1 (260 °C peak reflow) | Enables single-pass lead-free reflow assembly without moisture-related popcorn failure or delamination. |
Applications
| Automotive Sensor Protection | Industrial I/O Port 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 |
|---|---|---|---|
| SMBG6.0A-E3/52 | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs. M3). | Preferred for industrial-grade designs where halogen content is unrestricted. | Select when halogen-free requirement is absent and cost optimization is prioritized. |
| SMBG6.0AHM3/52 | Identical electrical and mechanical specs; adds AEC-Q101 qualification (HM3 suffix). | Required for automotive safety-critical subsystems (e.g., ADAS, braking ECUs). | Choose for automotive applications needing full AEC-Q101 validation beyond baseline qualification. |
Compared with SMBG6.0A-M3/52, the E3 variant offers identical protection performance at lower material cost but lacks halogen-free compliance, while the HM3 variant adds formal AEC-Q101 certification - enabling use in functional-safety domains where traceable qualification evidence is mandatory.

FAQ
What is the maximum clamping voltage of SMBG6.0A-M3/52 at its rated peak pulse current?
The SMBG6.0A-M3/52 has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPPM) of 58.3 A, measured using a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during a 600 W transient event and is critical for ensuring downstream ICs remain within their absolute maximum ratings. The SMBG6.0A-M3/52 maintains this clamping performance across its full operating temperature range.
Is SMBG6.0A-M3/52 suitable for automotive applications?
Yes, SMBG6.0A-M3/52 is qualified to AEC-Q101 standards, confirming its suitability for automotive applications including body electronics, infotainment, and sensor interfaces. It operates reliably from –55 °C to +150 °C, withstands 100 A surge current (8.3 ms), and meets MSL Level 1 for lead-free reflow. While the M3 suffix denotes halogen-free RoHS compliance, full AEC-Q101 validation is confirmed per Vishay documentation - making SMBG6.0A-M3/52 appropriate for non-safety-critical automotive systems.
How does the M3 suffix differ from E3 in SMBG6.0A-M3/52?
The M3 suffix in SMBG6.0A-M3/52 indicates halogen-free, RoHS-compliant construction meeting JEDEC J-STD-201 Class 2 whisker resistance, whereas E3 denotes RoHS compliance without halogen-free assurance. Both share identical electrical characteristics, package, and thermal performance. The M3 variant is required where halogen restrictions apply - such as in European automotive supply chains or green electronics initiatives - while E3 may be selected for cost-sensitive industrial applications without halogen mandates. SMBG6.0A-M3/52 thus serves stricter environmental compliance frameworks.
What is the standoff voltage and why is it important for SMBG6.0A-M3/52?
The standoff voltage (VWM) of SMBG6.0A-M3/52 is 6.0 V - the maximum DC or continuous reverse voltage the device can block without entering avalanche conduction. This parameter ensures the SMBG6.0A-M3/52 remains non-conductive during normal operation, preserving signal integrity and power rail stability. Selecting a VWM just above the system's maximum operating voltage (e.g., 5 V logic rails) prevents leakage or premature clamping while retaining sufficient margin for tolerance and temperature drift.
Can SMBG6.0A-M3/52 be used in bidirectional configurations?
No, SMBG6.0A-M3/52 is a unidirectional TVS diode, identifiable by its cathode band marking and specified parameters (e.g., IFSM = 100 A) that apply only in forward conduction. Bidirectional protection requires CA-suffixed variants like SMBG6.0CA, which lack polarity markings and exhibit symmetrical breakdown in both directions. Using SMBG6.0A-M3/52 in AC or floating signal paths would result in unintended forward conduction and possible failure. Always match polarity type to circuit topology - SMBG6.0A-M3/52 is strictly for DC-biased lines referenced to ground.
