Product details
Overview
SMBG10A-M3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping voltage transients on power and signal lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect automotive sensor interfaces and industrial I/O circuits against ESD and load dump.
For engineers reviewing the SMBG10A-M3/52 datasheet, SMBG10A-M3/52 pinout, SMBG10A-M3/52 application, or SMBG10A-M3/52 equivalent, key selection criteria include its 10 V stand-off rating, 17.0 V clamping performance at rated surge current, AEC-Q101 qualification, halogen-free M3 suffix compliance, and DO-215AA thermal resistance (RθJA = 100 °C/W).
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking. Its silicon junction is glass passivated for stability, and it delivers fast response time (<1 ns) and low incremental surge resistance to limit transient overvoltage before downstream ICs are damaged.
The SMBG10A-M3/52 is rated for -55 °C to +150 °C operating junction temperature, supports 100 A non-repetitive forward surge current (8.3 ms half-sine), and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - enabling robust use in automotive engine control units and industrial PLC modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse working voltage before clamping begins; sets upper limit for normal circuit operation. |
| VBR (min/max) | 11.1 V / 12.3 V at 1 mA - Confirmed breakdown threshold range; ensures reliable triggering above VWM with margin. |
| VC @ IPPM | 17.0 V at 35.3 A - Clamped voltage during 600 W transient; defines worst-case overvoltage seen by protected IC. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 µs waveform; validates protection capability against ISO 7637-2 Pulse 1/2/5a. |
| IFSM | 100 A - Single half-sine surge rating (8.3 ms); supports load-dump immunity in 12 V automotive systems. |
| TJ max | +150 °C - Maximum junction temperature; enables placement near heat sources in engine bay or motor drive PCBs. |
| Package | SMBG (DO-215AA) - Standardized surface-mount outline with 0.235" × 0.255" footprint and matte tin-plated leads per J-STD-002. |
Pinout & Package
SMBG10A-M3/52 uses the SMBG (DO-215AA) package: a low-profile, rectangular surface-mount case with two terminals, cathode marked by a band. Leads are matte tin-plated and solderable per J-STD-002. Mounting requires 5.0 mm × 5.0 mm copper pads per terminal for thermal derating compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to ground or lower-potential rail in unidirectional clamp configuration. | Completes conduction path during transient events; must be routed with low-inductance trace to minimize clamping overshoot. |
| Cathode | Current exit point in forward bias; connected to protected line (e.g., CAN_H, LIN, sensor supply) via series impedance. | Band-marked terminal; determines orientation during automated placement; ties to high-side of protected node for clamping action. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including powertrain and body electronics per stress test requirements. |
| Halogen-free (M3 suffix) | Complies with IEC 61249-2-21 and RoHS; eliminates brominated flame retardants without compromising UL 94 V-0 flammability rating. |
| 600 W peak pulse power | Handles ISO 7637-2 Pulse 5a (load dump) up to 12 V system level without degradation when mounted per recommended pad layout. |
| Low RθJA = 100 °C/W | Enables sustained operation under repetitive transients in enclosed enclosures; reduces need for additional thermal relief. |
| Glass-passivated junction | Improves long-term reliability and leakage stability across temperature and humidity; critical for 15-year automotive service life. |

IC Role / Device Role: Primary board-level TVS on upstream-facing USB ports meeting IEC 61000-4-2 ±15 kV contact discharge. Use Value: Halogen-free M3 construction satisfies medical device environmental compliance; 17.0 V clamping avoids USB 2.0 eye diagram distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBG10AHE3/52 | AEC-Q101 qualified; same electrical specs; E3 suffix = standard RoHS, non-halogen-free. | Preferred where halogen-free requirement is not mandated; identical thermal and clamping performance. | Select SMBG10AHE3/52 for cost-sensitive automotive modules without halogen restrictions. |
| SMBJ10A-M3 | Same VWM/VC, but SMBJ package (DO-214AB); RθJA = 110 °C/W; 600 W rating with larger footprint. | Used where higher thermal mass is needed; less suitable for ultra-dense layouts due to 0.280" × 0.180" size. | Choose SMBJ10A-M3 only if PCB layout allows larger package and thermal design requires extra margin. |
Compared with SMBG10AHE3/52 and SMBJ10A-M3, the SMBG10A-M3/52 uniquely combines AEC-Q101 qualification, halogen-free compliance, and the smallest standardized footprint (DO-215AA) among 600 W unidirectional TVS diodes - optimizing space-constrained automotive and industrial designs.

FAQ
What is the clamping voltage of SMBG10A-M3/52 at its rated peak pulse current?
The SMBG10A-M3/52 has a maximum clamping voltage (VC) of 17.0 V at 35.3 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The SMBG10A-M3/52 maintains this clamping performance across its full operating temperature range when mounted per Vishay's recommended 5.0 mm × 5.0 mm copper pad layout.
Is SMBG10A-M3/52 suitable for automotive applications?
Yes, SMBG10A-M3/52 is AEC-Q101 qualified and specifically designed for automotive use cases including engine control units, body electronics, and sensor interfaces. Its 150 °C maximum junction temperature, 100 A surge rating, and halogen-free M3 construction meet stringent automotive environmental and safety requirements. The SMBG10A-M3/52 is validated for ISO 7637-2 load dump and ISO 16750-2 transient immunity testing when implemented per Vishay's layout guidelines.
What does the "M3" suffix mean in SMBG10A-M3/52?
The "M3" suffix in SMBG10A-M3/52 indicates halogen-free, RoHS-compliant construction meeting IEC 61249-2-21, with material content verified per Vishay's specification. It also denotes compliance with JESD 201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow profile (260 °C peak). The SMBG10A-M3/52 shares identical electrical characteristics with E3-suffix variants but adds environmental compliance required for modern automotive and medical electronics.
How does SMBG10A-M3/52 differ from SMBG10CA-M3/52?
SMBG10A-M3/52 is unidirectional with cathode-band polarity, while SMBG10CA-M3/52 is bidirectional and symmetrical - meaning it clamps in both directions with no polarity marking. The SMBG10A-M3/52 is intended for DC-biased lines like power rails or single-ended signals, whereas SMBG10CA-M3/52 suits AC-coupled or differential lines such as CAN or RS-485. Their VBR, VC, and PPPM ratings are identical, but circuit integration differs fundamentally.
What is the thermal resistance of SMBG10A-M3/52?
The SMBG10A-M3/52 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. This value assumes FR-4 PCB with no internal planes; adding thermal vias or ground planes reduces effective RθJA. The SMBG10A-M3/52's low RθJA supports operation under repetitive transients without exceeding its 150 °C TJ limit in compact industrial modules.
