Product details
Overview
SMBJ6.0D-M3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, with 6.77 V to 7.27 V breakdown voltage (VBR), 6.0 V stand-off voltage (VWM), and 600 W peak pulse power rating at 10/1000 μs waveform. It clamps transients to ≤10.2 V at 58.9 A peak surge current and is used for protecting MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the SMBJ6.0D-M3/I datasheet, SMBJ6.0D-M3/I pinout, SMBJ6.0D-M3/I application, or SMBJ6.0D-M3/I equivalent, key selection criteria include unidirectional polarity, ±3.5 % VBR tolerance, low leakage (<500 μA at VWM), M3 halogen-free RoHS-compliant construction, and J-STD-020 MSL Level 1 compatibility.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuit nodes, conducting only when reverse voltage exceeds VBR to limit transient overvoltage. Its low incremental surge resistance and fast response time ensure effective suppression of inductive switching spikes and ESD events.
The SMBJ6.0D-M3/I is rated for 150 °C maximum junction temperature, with thermal resistance RθJA = 125 °C/W on minimum pad layout and RθJM = 20 °C/W to mount. It meets UL 497B recognition (QVGQ2) and complies with JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.77 V / 7.27 V - defines precise clamping onset threshold with ±3.5 % tolerance for predictable protection margin |
| VWM | 6.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| IPPM | 58.9 A - peak surge current it safely shunts during 10/1000 μs transient without failure |
| VC @ IPPM | ≤10.2 V - clamped voltage seen by protected circuit under full-rated surge, limiting stress on downstream components |
| PPPM | 600 W - peak pulse power dissipation capability per standard 10/1000 μs waveform at 0.01 % duty cycle |
| ID @ VWM | ≤500 μA - ensures minimal standby power loss and no interference with low-current signal paths |
| TJ max | 150 °C - enables reliable operation in high-temperature industrial environments without derating |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102; polarity indicated by cathode band on unidirectional types.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or lower-potential node in unidirectional configuration; allows normal forward bias operation only during fault conditions |
| Cathode (banded end) | Reverse-biased clamping terminal | Connected to protected line; conducts avalanche current when line voltage exceeds VBR, diverting surge energy to ground |
Key Features
| Feature | Design Value |
|---|---|
| ±3.5 % VBR tolerance | Enables tighter design margins and consistent clamping behavior across production lots without system-level recalibration |
| 600 W peak pulse power (10/1000 μs) | Supports robust protection against high-energy transients such as lightning-induced surges or inductive kickback in motor drives |
| MSL Level 1 (260 °C peak) | Allows direct placement into standard lead-free reflow profiles without pre-baking, reducing manufacturing complexity |
| M3 suffix compliance | Guarantees halogen-free, RoHS-compliant, industrial-grade construction with JESD201 Class 2 whisker resistance for long-term reliability |
| Low leakage (<500 μA at VWM) | Prevents signal distortion or power drain in high-impedance sensor interfaces and battery-powered applications |
Applications

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/I | Same VBR range (6.77–7.27 V), identical package and ratings, but lacks UL 497B recognition | Not certified for telecom or safety-critical surge protection requiring UL listing | Select SMBJ6.0D-M3/I when UL 497B compliance and QVGQ2 file E136766 are required |
| SMCJ6.0A | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VBR/VWM specs | Used where higher surge energy absorption is needed and board space permits larger footprint | Choose SMBJ6.0D-M3/I for space-constrained designs needing 600 W protection in SMB outline |
Compared with SMBJ6.0A-M3/I, the SMBJ6.0D-M3/I adds UL 497B certification for telecom infrastructure use; versus SMCJ6.0A, it trades 1500 W surge capacity for 40 % smaller PCB area in DO-214AA.

FAQ
What is the breakdown voltage range for SMBJ6.0D-M3/I?
The SMBJ6.0D-M3/I has a guaranteed breakdown voltage (VBR) range of 6.77 V to 7.27 V at 10 mA test current, corresponding to ±3.5 % tolerance around the nominal 6.0 V stand-off rating. This tight tolerance ensures consistent clamping behavior across production units and simplifies system-level margin analysis without requiring derating headroom beyond datasheet limits.
Is SMBJ6.0D-M3/I suitable for bidirectional transient protection?
No, SMBJ6.0D-M3/I is a unidirectional TVS diode, indicated by the "D" (not "CD") suffix and presence of a cathode band. For bidirectional protection-such as AC line or data bus applications-Vishay specifies parts with the "CD" suffix (e.g., SMBJ6.0CD). Using SMBJ6.0D-M3/I in reverse-biased configurations risks permanent damage due to lack of symmetrical avalanche capability.
What does the "M3" suffix mean in SMBJ6.0D-M3/I?
"M3" denotes Vishay's halogen-free, RoHS-compliant, industrial-grade construction with matte tin-plated leads qualified to JESD201 Class 2 for whisker resistance. It also confirms compliance with J-STD-020 MSL Level 1 (peak reflow temperature 260 °C), enabling compatibility with standard lead-free assembly processes without pre-bake requirements.
Does SMBJ6.0D-M3/I have UL recognition?
Yes, SMBJ6.0D-M3/I carries Underwriters Laboratory recognition under file E136766 for both unidirectional and bidirectional variants, meeting UL 497B requirements for primary protectors in telecommunications and industrial equipment. This certification validates its performance under standardized surge waveforms and supports regulatory compliance in safety-critical deployments.
What is the maximum clamping voltage of SMBJ6.0D-M3/I at rated surge current?
The SMBJ6.0D-M3/I clamps to a maximum of 10.2 V when subjected to its rated peak pulse current (IPPM) of 58.9 A under the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the worst-case voltage imposed on the protected circuit during full-rated transient events, ensuring downstream ICs remain within absolute maximum ratings.
