Product details
Overview
SMBJ60D-M3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping inductive switching transients and ESD events on power and signal lines. It features a 60 V stand-off voltage (VWM), 67.7–72.7 V breakdown voltage (VBR) at 1 mA, 95.5 V maximum clamping voltage (VC) at 6.28 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the SMBJ60D-M3/I datasheet, SMBJ60D-M3/I pinout, SMBJ60D-M3/I application, or SMBJ60D-M3/I equivalent, key selection criteria include clamping performance under 6.28 A surge, thermal resistance (RθJA = 125 °C/W on minimum pad), unidirectional polarity with cathode band marking, and industrial-grade halogen-free M3 construction compliant with JESD 201 Class 2 whisker testing.
Technical Context
This TVS diode operates as a voltage-clamping protection device, triggered when reverse voltage exceeds its breakdown threshold (VBR), diverting transient energy to ground while limiting downstream voltage to ≤95.5 V. Its low incremental surge resistance and fast response time ensure effective suppression of lightning-induced surges and inductive kickback.
The SMBJ60D-M3/I is rated for 150 °C maximum junction temperature, supports 0.5 μA max reverse leakage at 60 V, and delivers 600 W peak pulse power under standardized 10/1000 μs waveform with 0.01 % duty cycle. Its M3 suffix confirms halogen-free, RoHS-compliant, industrial-grade construction with matte tin-plated leads solderable per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 67.7 V / 72.7 V at 1 mA - Tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 95.5 V at 6.28 A - Clamping voltage during full-rated 600 W transient, defining protected circuit stress level |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform, critical for IEC 61000-4-5 compliance margin |
| ID @ VWM | 0.5 μA - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits |
| RθJA | 125 °C/W - Thermal resistance on minimum recommended PCB pad; dictates derating above 25 °C ambient |
| Polarity | Unidirectional - Cathode band denotes terminal; blocks forward conduction, clamps reverse transients only |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, M3 grade. Cathode band marks the cathode terminal; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VLINE > VBR |
| Anode (unbanded end) | Reference/ground return | Typically tied to system ground or low-impedance return path; completes clamping loop |
Key Features
| Feature | Design Value |
|---|---|
| ±3.5 % VBR tolerance | Enables precise overvoltage threshold setting without design margin inflation |
| 600 W peak pulse power | Supports robust protection against IEC 61000-4-5 Level 4 (4 kV) surges on 50 Ω source impedance |
| Low 0.5 μA leakage at 60 V | Minimizes loading on high-impedance sensor outputs or battery-backed circuits |
| MSL Level 1 (260 °C peak) | Enables standard SMT reflow without moisture sensitivity concerns or baking requirements |
| M3 industrial-grade construction | Meets JESD 201 Class 2 whisker resistance, ensuring long-term reliability in automotive/industrial environments |

Use Value: Maintains functional operation of microcontrollers and audio codecs during 35 V/100 ms load-dump events. |
| Telecom Ethernet Port ESD | Consumer Appliance Sensor Interface |
Use Scenario: Protecting RJ45 PHY interface pins from human-body-model (HBM) and IEC 61000-4-2 contact discharge. IC Role / Device Role / Timing Role: Bidirectional-capable layout (though SMBJ60D-M3/I is unidirectional, used in back-to-back configuration or with series impedance) for fast transient shunting. Use Value: Limits voltage excursion to <95.5 V during 8 kV contact ESD, preventing PHY IC damage without adding capacitance that degrades 100BASE-TX signal integrity. | Use Scenario: Shielding temperature/humidity sensor analog outputs from ESD events during factory handling or user interaction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A-M3/I | Bidirectional variant; symmetric clamping in both polarities; same VWM (60 V), VC (95.5 V), and PPPM (600 W) | Required where AC-coupled lines or reversible polarity connections exist (e.g., RS-485, USB D+/D−) | Select SMBJ60A-M3/I only if bidirectional protection is needed; SMBJ60D-M3/I is optimal for DC rails with defined polarity. |
| SMCJ60AHE3_A/H | Higher-power SMC (DO-214AB) package; 1500 W PPPM; same VWM/VBR/VC specs but larger footprint and higher RθJA (60 °C/W) | Suitable for higher-energy transients where board space allows larger package and thermal mass | Choose SMCJ60AHE3_A/H when surge energy exceeds 600 W capability or when enhanced thermal performance on copper pour is required. |
Compared with SMBJ60A-M3/I and SMCJ60AHE3_A/H, the SMBJ60D-M3/I offers optimal balance of compact SMB footprint, tight VBR tolerance, and industrial-grade M3 reliability for unidirectional DC rail protection-without over-specifying power or size.

FAQ
What is the maximum clamping voltage of SMBJ60D-M3/I under full-rated surge current?
The SMBJ60D-M3/I has a maximum clamping voltage (VC) of 95.5 V at 6.28 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value defines the highest voltage imposed on protected circuitry during a 600 W transient event and is guaranteed across the operating temperature range per Vishay's datasheet specification 87606.
Is SMBJ60D-M3/I suitable for protecting 3.3 V logic interfaces?
No - SMBJ60D-M3/I is not suitable for direct protection of 3.3 V logic interfaces because its 60 V stand-off voltage (VWM) and 67.7 V minimum breakdown voltage (VBR) far exceed safe operating limits for low-voltage ICs. It is intended for 12–48 V power rails or high-voltage signal lines; use lower-voltage TVS like SMBJ3.3A for 3.3 V logic.
Does SMBJ60D-M3/I have a bidirectional version?
Yes - the bidirectional counterpart is SMBJ60A-M3/I, which uses the same SMB package and shares identical VWM (60 V), VBR (67.7–72.7 V), VC (95.5 V), and PPPM (600 W) ratings, but provides symmetrical clamping for AC or polarity-agnostic applications. The "D" suffix in SMBJ60D-M3/I explicitly denotes unidirectional polarity.
What does the "M3" suffix indicate in SMBJ60D-M3/I?
"M3" indicates halogen-free, RoHS-compliant, industrial-grade construction meeting JESD 201 Class 2 whisker resistance, matte tin-plated leads solderable per J-STD-002, and UL 94 V-0 molding compound. It also specifies tape-and-reel packaging: "I" denotes 13-inch reels with 3200 units per reel, per Vishay's ordering information in document 87606.
Can SMBJ60D-M3/I be used in place of SMBJ60A-M3/I for DC power rail protection?
Yes - SMBJ60D-M3/I is appropriate for unidirectional DC power rail protection (e.g., +12 V to ground), where polarity is fixed and only reverse transients require suppression. Unlike SMBJ60A-M3/I, it does not clamp positive-going transients relative to ground, making it more efficient for single-polarity rails and eliminating unnecessary conduction during normal operation.
