Product details
Overview
SMBG60A-M3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMBG (DO-215AA) package, rated for 60 V stand-off voltage, 66.7–73.7 V breakdown at 1 mA, 96.8 V clamping voltage at 6.2 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform - deployed for overvoltage protection of automotive power rails and industrial sensor interfaces.
For engineers reviewing the SMBG60A-M3/52 datasheet, SMBG60A-M3/52 pinout, SMBG60A-M3/52 application, or SMBG60A-M3/52 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, IPPM derating above 25 °C, unidirectional polarity alignment with DC bias, and M3 halogen-free RoHS compliance for automotive-grade production.
Technical Context
This TVS diode operates as a shunt-clamping device triggered by reverse-biased avalanche breakdown, with glass-passivated junction ensuring stable VBR tolerance and low leakage (<1.0 μA at 60 V). Its 100 °C/W junction-to-ambient thermal resistance requires PCB copper pad design per Vishay's 5.0 mm × 5.0 mm recommendation to sustain repetitive 0.01% duty cycle surges.
The SMBG60A-M3/52 is AEC-Q101 qualified and rated for -55 °C to +150 °C operation, supporting automotive ECU and body control module designs where transient immunity to ISO 7637-2 pulse 1/2a/3a and IEC 61000-4-5 surge events is mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before leakage exceeds 1.0 μA; sets upper limit for protected line DC bias. |
| VBR @ IT = 1 mA | 66.7–73.7 V - Breakdown voltage range defining reliable avalanche initiation threshold under standardized test conditions. |
| VC @ IPPM = 6.2 A | 96.8 V - Clamped voltage during 10/1000 μs surge; determines maximum stress on downstream ICs during transients. |
| PPPM | 600 W - Peak pulse power handling capability; defines survivability against standardized lightning/surge waveforms. |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); relevant for inadvertent forward fault conditions. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments with minimal thermal margin loss. |
| Package | SMBG (DO-215AA) - Surface-mount outline with 0.235–0.255" length, 0.130–0.155" width, and 0.075–0.095" height; compatible with automated pick-and-place. |
Pinout & Package
SMBG60A-M3/52 uses the SMBG (DO-215AA) package: a gull-wing surface-mount case with two terminals, cathode marked by a band on the body. The device is unidirectional; polarity must be observed during PCB layout to ensure correct clamping direction relative to DC rail.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to system ground or lowest potential node; forms return path during clamping event. |
| Cathode | Protected-line interface terminal | Connected to line being protected (e.g., 12 V battery rail); avalanche conduction occurs when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics per stress test requirements including HTOL, TC, and HAST - enabling use in engine control and ADAS modules. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets JESD201 Class 2 whisker resistance and EU RoHS Directive 2011/65/EU without brominated flame retardants - required for Tier 1 automotive supply chain. |
| 600 W peak pulse power (10/1000 μs) | Withstands ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 2a (load dump simulation) without degradation when mounted on specified 5.0 mm × 5.0 mm copper pads. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD or relay bounce), improving protection margin for 3.3 V/5 V logic interfaces. |
| MSL Level 1 (J-STD-020) | Unlimited floor life at ≤30 °C/60% RH; supports standard SMT reflow without baking - reduces manufacturing overhead in high-volume assembly. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-supplied ECUs from load dump and alternator transients in passenger vehicles. IC Role / Device Role / Timing Role: Shunt-clamping TVS placed between battery rail and ground, activated within <1 ns upon exceeding VBR.

IC Role / Device Role / Timing Role: Unidirectional TVS placed after bridge rectifier and before bulk capacitor, clamping positive-going spikes on DC bus. Use Value: Enables UL 62368-1 compliance by limiting transient overvoltage to safe levels for electrolytic capacitor and controller IC ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBG60AHE3/52 | AEC-Q101 qualified; same VWM, VBR, VC, and PPPM; E3 suffix denotes standard RoHS (non-halogen-free) plating. | Acceptable where halogen-free requirement is not enforced (e.g., non-automotive industrial designs). | Select SMBG60AHE3/52 if AEC-Q101 qualification is needed but halogen-free material is optional. |
| SMBJ60A-M3 | Same VWM and VC, but SMBJ package (DO-214AB) has larger footprint (4.58 × 3.94 mm vs. SMBG's 6.48 × 3.94 mm) and higher RθJA (125 °C/W). | Less suitable for space-constrained automotive modules; requires larger PCB area and more thermal relief. | Choose SMBG60A-M3/52 over SMBJ60A-M3 when board space is limited and thermal performance at elevated ambient is critical. |
Compared with SMBG60AHE3/52 and SMBJ60A-M3, SMBG60A-M3/52 uniquely combines halogen-free construction, AEC-Q101 qualification, and compact SMBG packaging - delivering optimal balance of regulatory compliance, reliability, and layout efficiency for next-generation automotive electronics.

FAQ
What is the clamping voltage of SMBG60A-M3/52 and how is it measured?
The SMBG60A-M3/52 has a maximum clamping voltage (VC) of 96.8 V, measured at a peak pulse current (IPPM) of 6.2 A using a standardized 10/1000 μs double-exponential waveform. This value reflects the actual voltage seen by downstream circuitry during surge events and is guaranteed per Vishay's datasheet revision 09-Jan-2024, Document Number 88456. The SMBG60A-M3/52 achieves this clamping performance due to its low incremental surge resistance and optimized silicon junction design.
Is SMBG60A-M3/52 suitable for automotive applications?
Yes, SMBG60A-M3/52 is AEC-Q101 qualified and rated for operation from -55 °C to +150 °C, making it suitable for under-hood and cabin automotive applications including body control modules, infotainment power supplies, and ADAS sensor interfaces. Its halogen-free (M3) construction meets Tier 1 automotive material requirements, and the SMBG package supports automated assembly per J-STD-020 MSL Level 1. The SMBG60A-M3/52 is explicitly validated for ISO 7637-2 transient immunity in Vishay's qualification testing.
What does the "M3" suffix mean in SMBG60A-M3/52?
The "M3" suffix in SMBG60A-M3/52 indicates halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD201 Class 2 whisker resistance, and industrial-grade reliability. It distinguishes the part from E3 (standard RoHS, non-halogen-free) and HM3 (AEC-Q101 qualified + halogen-free) variants. The SMBG60A-M3/52 carries the M3 designation and is also AEC-Q101 qualified per Vishay's ordering matrix - confirmed in the "MECHANICAL DATA" section of the datasheet.
How does SMBG60A-M3/52 differ from bidirectional TVS diodes like SMBG60CA-M3/52?
SMBG60A-M3/52 is unidirectional and features a cathode band for polarity-sensitive placement, while SMBG60CA-M3/52 is bidirectional with no polarity marking and symmetrical breakdown in both directions. The unidirectional SMBG60A-M3/52 offers lower leakage (<1.0 μA at 60 V) and is intended for DC-biased lines such as automotive battery rails. In contrast, SMBG60CA-M3/52 is used in AC-coupled or floating signal paths. Both share identical VWM, VBR, and PPPM, but their circuit roles and layout requirements differ fundamentally - the SMBG60A-M3/52 must be oriented correctly to function.
What PCB layout guidance applies to SMBG60A-M3/52 for optimal thermal and electrical performance?
Vishay specifies mounting SMBG60A-M3/52 on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and manage thermal dissipation. Traces to the SMBG60A-M3/52 should be short and wide to minimize inductance, especially on the cathode side, and ground planes must be solid beneath the device. The SMBG60A-M3/52's thermal resistance (RθJA = 100 °C/W) assumes this pad layout; reduced copper area increases junction temperature and degrades surge endurance.
