Product details
Overview
SMBG6.0A-M3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 μs), clamping voltage of 10.3 V at 58.3 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG6.0A-M3/5B datasheet, SMBG6.0A-M3/5B pinout, SMBG6.0A-M3/5B application, or SMBG6.0A-M3/5B equivalent, key selection criteria include clamping performance under 10/1000 μs surge, unidirectional polarity with cathode band marking, DO-215AA (SMBG) surface-mount package compatibility, and halogen-free RoHS compliance per M3 suffix.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM = 6.0 V and rapidly transitions to low-impedance conduction above VBR (min 6.67 V) to limit transient voltages. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
It is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine), supports operating junction temperatures from –55 °C to +150 °C, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak, enabling compatibility with standard SMT assembly processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VWM | 6.0 V - Maximum continuous reverse working voltage before clamping initiates |
| VBR @ 10 mA | 6.67–7.37 V - Confirmed breakdown range ensuring reliable turn-on during transients |
| VC @ IPPM | 10.3 V at 58.3 A - Clamped voltage during 600 W 10/1000 μs surge, limiting downstream stress |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against ISO 7637-2 load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between power input and ground, absorbing energy before it reaches LDOs or microcontrollers. Use Value: Limits clamped voltage to ≤10.3 V during 58.3 A surge, preserving 5 V/3.3 V logic supply integrity and preventing latch-up in downstream ASICs. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) in PLC I/O modules exposed to field wiring transients. IC Role / Device Role / Timing Role: Line-side TVS on 4–20 mA or 0–10 V signal paths, shunting induced spikes before they reach precision ADC front-ends. Use Value: Sub-100 ns response ensures clamping occurs before sensitive op-amps or SAR ADCs experience overvoltage damage or data corruption. |
| Consumer Power Adapter Input Stage | Telecom DC Feeder Protection |
Use Scenario: Secondary-side overvoltage suppression in USB-C PD adapters and AC/DC wall adapters. IC Role / Device Role / Timing Role: Standoff-rated TVS across output capacitor terminals to clamp flyback leakage spikes and cross-regulation overshoot. Use Value: 6.0 V VWM allows integration with 5 V output rails while maintaining >1.5 V margin to VBR, avoiding false triggering during normal ripple. | Use Scenario: DC power feed protection in PoE-powered base stations and remote radio units. IC Role / Device Role / Timing Role: Per-port TVS on 48 V DC input lines to absorb lightning-induced surges and hot-swap transients. Use Value: 600 W rating supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) compliance when paired with appropriate series impedance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-M3/5B | Same VWM (6.0 V), but lower PPPM = 600 W (same rating), higher VC = 10.5 V at same IPPM; SMB (DO-214AA) package, slightly larger footprint | Compatible in board space-constrained designs where DO-215AA is unavailable; identical clamping performance within tolerance | Select SMBJ6.0A-M3/5B only if legacy layout uses SMB footprint; SMBG offers tighter thermal resistance (RθJL = 20 °C/W vs. ~25 °C/W) |
| SMCJ6.0A-M3/5B | Same VWM and VBR, but higher PPPM = 1500 W; SMC (DO-214AB) package, 2× footprint area and 3× thermal mass | Used where higher surge repetition rate or longer duration transients require greater energy absorption | Choose SMCJ6.0A-M3/5B only when tested surge profiles exceed 600 W; otherwise SMBG6.0A-M3/5B provides optimal size-to-performance ratio |
Compared with SMBJ6.0A-M3/5B and SMCJ6.0A-M3/5B, SMBG6.0A-M3/5B delivers identical 6.0 V standoff and 600 W surge capability in the smallest qualified surface-mount TVS package (DO-215AA), enabling higher board density and improved thermal response in automotive and industrial PCB layouts.

FAQ
What is the clamping voltage of SMBG6.0A-M3/5B at its rated peak pulse current?
The SMBG6.0A-M3/5B has a maximum clamping voltage (VC) of 10.3 V when subjected to its peak pulse current (IPPM) of 58.3 A under the standard 10/1000 μs waveform. This value is measured and guaranteed per Vishay's datasheet revision 09-Jan-2024, Document Number 88456, and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBG6.0A-M3/5B maintains this clamping performance across its full operating temperature range.
Is SMBG6.0A-M3/5B suitable for automotive applications?
Yes, SMBG6.0A-M3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including engine control modules, body electronics, and ADAS sensor interfaces. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and guaranteed operation from –55 °C to +150 °C. The "M3" suffix confirms halogen-free, RoHS-compliant materials meeting automotive material categorization standards. SMBG6.0A-M3/5B is listed in Vishay's qualified automotive product portfolio per document 88456.
How does the SMBG6.0A-M3/5B differ from the SMBG6.0CA-M3/5B variant?
The SMBG6.0A-M3/5B is unidirectional, with polarity indicated by a cathode band and intended for DC line-to-ground protection. In contrast, SMBG6.0CA-M3/5B is bidirectional, offering symmetrical clamping for AC-coupled or floating signal lines, with no polarity marking. Their VBR ranges differ slightly: SMBG6.0A-M3/5B specifies 6.67–7.37 V, while SMBG6.0CA-M3/5B has a minimum VBR of 6.4 V. Both share identical PPPM (600 W), package (SMBG), and M3 environmental compliance. SMBG6.0A-M3/5B cannot substitute for SMBG6.0CA-M3/5B in bidirectional applications.
What is the thermal resistance of SMBG6.0A-M3/5B, and how does it affect layout design?
The SMBG6.0A-M3/5B has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. This means efficient heat extraction relies heavily on copper pad area and via stitching to internal ground planes. For high-duty-cycle surge environments, designers should maximize pad size and add ≥2 thermal vias per lead connected to solid inner-layer ground planes. The low RθJL enables rapid transient heat dissipation into the PCB, making SMBG6.0A-M3/5B well-suited for thermally demanding automotive placements.
Does SMBG6.0A-M3/5B meet UL recognition requirements?
Yes, SMBG6.0A-M3/5B carries Underwriters Laboratories (UL) recognition under file number E136766 for both unidirectional and bidirectional TRANSZORB® devices, complying with UL 497B for primary protector classification. This certification covers safety-related parameters including flammability (UL 94 V-0 molding compound), surge endurance, and insulation integrity. The UL listing applies directly to the SMBG6.0A-M3/5B as manufactured and tested per Vishay's qualification protocol, and is documented in datasheet 88456, footnote (+).
