Product details
Overview
SMBJ6.0CD-M3/I from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 6.0 V stand-off voltage (VWM), 6.77–7.27 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 μs), and clamps to ≤10.2 V at 58.9 A peak surge current - used in sensor interface protection and industrial I/O line safeguarding.
For engineers reviewing the SMBJ6.0CD-M3/I datasheet, SMBJ6.0CD-M3/I pinout, SMBJ6.0CD-M3/I application, or SMBJ6.0CD-M3/I equivalent, key selection criteria include bidirectional polarity, ±3.5 % VBR tolerance, MSL Level 1 moisture sensitivity, halogen-free RoHS-compliant construction, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This bidirectional TVS operates symmetrically in both forward and reverse directions, enabling robust protection of AC-coupled or differential signal paths without polarity constraints. Its low clamping ratio (VC/VBR ≈ 1.43) and fast response time ensure effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The device is rated for 150 °C maximum junction temperature and exhibits 125 °C/W thermal resistance (junction-to-ambient, mounted on minimum recommended pad layout). It meets UL 497B recognition (QVGQ2) and complies with JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse stand-off voltage before significant leakage; defines safe operating margin below breakdown. |
| VBR min/max | 6.77 V / 7.27 V at 10 mA - Tight ±3.5 % tolerance ensures predictable turn-on across production lots. |
| VC @ IPPM | ≤10.2 V at 58.9 A - Clamping voltage under 600 W 10/1000 μs surge; limits downstream IC stress during transient events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA-E3/52 (Vishay) | Same electrical specs and SMB package; differs only in packaging (tape/reel size) and M3 vs. E3 suffix - E3 indicates legacy halogen-containing version. | No functional difference in circuit operation; E3 variant lacks halogen-free certification and JESD201 Class 2 whisker compliance. | Select SMBJ6.0CD-M3/I for RoHS/halogen-free compliance and extended reliability in high-reliability industrial programs. |
| P6SMB6.0CA (ON Semiconductor) | Identical VWM (6.0 V), VBR (6.77–7.27 V), VC (10.2 V), and PPPM (600 W); same SMB package but slightly higher ID (1000 μA max vs. 500 μA). | Higher leakage may affect ultra-low-power sensor nodes; otherwise interchangeable in most industrial and telecom surge protection roles. | Choose P6SMB6.0CA only if legacy qualification or dual-sourcing mandates ON Semi parts; verify leakage impact in battery-powered designs. |
Compared with SMBJ6.0CD-M3/I, the Vishay SMBJ6.0CA-E3/52 offers identical clamping performance but lacks halogen-free and whisker-resistant certifications, while the ON Semiconductor P6SMB6.0CA trades tighter leakage for broader second-source availability - making SMBJ6.0CD-M3/I optimal for new designs requiring full industrial compliance.

FAQ
What is the polarity configuration of SMBJ6.0CD-M3/I?
The SMBJ6.0CD-M3/I is a bidirectional TVS diode with symmetrical terminal behavior - neither end is marked as anode or cathode. This allows it to clamp overvoltage transients equally in both directions, making it ideal for protecting AC-coupled signals, differential buses like RS-485, or any line where polarity cannot be guaranteed during surge events. The device has no cathode band marking.
Does SMBJ6.0CD-M3/I meet UL recognition standards?
Yes, SMBJ6.0CD-M3/I is Underwriters Laboratory (UL) recognized under standard UL 497B for protectors, with file number E136766. This applies to both unidirectional and bidirectional variants in the SMBJ family. The recognition covers its use in primary and secondary circuit protection applications, confirming compliance with safety requirements for transient voltage suppressors in commercial and industrial equipment.
What is the maximum clamping voltage of SMBJ6.0CD-M3/I under surge conditions?
The SMBJ6.0CD-M3/I clamps to a maximum of 10.2 V when subjected to its rated 58.9 A peak pulse current (IPPM), defined by the 10/1000 μs waveform. This clamping voltage is measured at the device terminals and represents the upper limit of voltage seen by downstream circuitry during a 600 W transient event - critical for ensuring connected ICs remain within absolute maximum ratings.
Can SMBJ6.0CD-M3/I be used in automotive applications?
SMBJ6.0CD-M3/I is not AEC-Q200 qualified and is specified for industrial-grade operation (−55 °C to +150 °C junction temperature). While its electrical specs and robustness make it suitable for under-hood or infotainment peripheral protection in some cases, Vishay does not certify it for automotive safety-critical systems. For automotive use, consult Vishay's AEC-Q200-qualified TVS portfolio such as the AUTOMOTIVE SMBJ series.
How does the M3 suffix affect SMBJ6.0CD-M3/I's reliability and processing?
The M3 suffix on SMBJ6.0CD-M3/I denotes halogen-free, RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 2 whisker resistance. It also confirms MSL Level 1 rating - meaning the device can be reflowed at 260 °C peak without baking, supporting high-yield, low-risk SMT assembly in industrial and telecom manufacturing environments.
