Product details
Overview
SMB10J6.0A-M3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1000 W peak pulse power (10/1000 µs), 97.1 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge. Used in automotive ECUs and industrial sensor interfaces to protect MOSFETs and microcontrollers from inductive switching transients.
For engineers reviewing the SMB10J6.0A-M3/5B datasheet, SMB10J6.0A-M3/5B pinout, SMB10J6.0A-M3/5B application, or SMB10J6.0A-M3/5B equivalent, key selection criteria include clamping voltage under 10.3 V at 97.1 A, unidirectional polarity with cathode band marking, halogen-free RoHS-compliant M3 suffix, and AEC-Q101 qualification readiness via HM3 variant.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM (6.0 V), avalanches sharply at VBR (6.67–7.37 V), and limits transient energy by diverting surge current to ground while holding VC ≤10.3 V. Its glass-passivated junction ensures stable breakdown and low leakage (<1000 µA at VWM).
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 72 °C/W (junction-to-ambient on 5.0 mm × 5.0 mm copper pads). It meets MSL Level 1 per J-STD-020 and supports reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before conduction begins; sets upper limit for protected circuit's normal DC rail. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed avalanche onset range; ensures reliable triggering above system nominal voltage. |
| VC @ IPPM | ≤10.3 V at 97.1 A - Clamping voltage during full 1000 W surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 1000 W (10/1000 µs) - Peak surge power handling; defines protection level against IEC 61000-4-5 Level 4 transients. |
| IFSM | 100 A (8.3 ms half-sine) - Non-repetitive forward surge rating; supports inrush or fault-current events without failure. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| Polarity | Unidirectional - Cathode-band marked; blocks reverse current until breakdown, ideal for DC supply line protection. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); cathode band denotes terminal 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (cathode band) | Anode connection for unidirectional operation | Connected to protected line (e.g., +12 V rail); conducts surge current toward ground when voltage exceeds VBR. |
| Terminal 2 | Cathode connection | Connected to system ground; provides low-inductance return path for clamped surge current. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, repeatable VBR and low leakage (<1000 µA at VWM) across temperature and lifetime. |
| Low incremental surge resistance | Enables tight clamping (VC ≤10.3 V) even at 97.1 A, minimizing voltage overshoot on protected nodes. |
| AEC-Q101 qualification pathway | M3 suffix supports automotive-grade builds; HM3 variant is fully AEC-Q101 qualified for ECU and ADAS applications. |
| MSL Level 1 moisture sensitivity | Allows standard SMT reflow without baking; compatible with high-volume automated assembly at 260 °C peak. |
| UL 94 V-0 molding compound | Provides flame-retardant encapsulation required for industrial and automotive safety compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-M3/5B | Same SMB package, identical VWM/VBR/VC specs, but lower PPPM (600 W vs. 1000 W). | Not suitable for IEC 61000-4-5 Level 4; limited to lower-energy transients in consumer-grade designs. | Select SMBJ6.0A-M3/5B only if surge requirements are ≤600 W and cost optimization is critical. |
| SMB10J6.0AHE3_B/I | Same electrical specs, E3 suffix (RoHS commercial grade), 13" tape; lacks halogen-free and AEC-Q101 qualification. | Acceptable for non-automotive industrial use where halogen-free or automotive qualification is not mandated. | Choose SMB10J6.0AHE3_B/I for cost-sensitive commercial applications without automotive compliance needs. |
Compared with SMBJ6.0A-M3/5B and SMB10J6.0AHE3_B/I, SMB10J6.0A-M3/5B delivers 67% higher surge power handling and halogen-free compliance-critical for automotive Tier-1 suppliers requiring both robustness and material sustainability.

FAQ
What is the clamping voltage of SMB10J6.0A-M3/5B at its rated peak pulse current?
The SMB10J6.0A-M3/5B clamps to a maximum of 10.3 V at its rated peak pulse current of 97.1 A (10/1000 µs waveform). This value is measured under standardized test conditions and guarantees that downstream components experience no more than 10.3 V during full-rated surge events, making SMB10J6.0A-M3/5B suitable for protecting 5 V and 3.3 V logic rails in automotive and industrial systems.
Is SMB10J6.0A-M3/5B qualified for automotive applications?
SMB10J6.0A-M3/5B itself carries the halogen-free, RoHS-compliant M3 suffix and meets MSL Level 1 and J-STD-020 reflow standards. While not AEC-Q101 qualified out-of-box, its HM3 variant (e.g., SMB10J6.0AHM3_B/I) is fully AEC-Q101 qualified. Engineers selecting SMB10J6.0A-M3/5B for automotive use should verify qualification status with Vishay documentation or specify HM3 for certified compliance.
What does the "-M3/5B" suffix indicate in SMB10J6.0A-M3/5B?
The "-M3/5B" suffix in SMB10J6.0A-M3/5B specifies two attributes: "M3" denotes halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance, and "/5B" indicates packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This format ensures compatibility with high-speed SMT placement equipment and satisfies environmental compliance requirements for global manufacturing.
How does SMB10J6.0A-M3/5B compare to bidirectional TVS diodes like SMB8J6.0CA-M3/5B?
SMB10J6.0A-M3/5B is unidirectional with 1000 W PPPM, while SMB8J6.0CA-M3/5B is bidirectional with 800 W PPPM and symmetric breakdown. The unidirectional SMB10J6.0A-M3/5B offers superior surge handling for DC rails where polarity is fixed, whereas SMB8J6.0CA-M3/5B suits AC-coupled or dual-polarity signal lines. Their VWM, VBR, and VC values are closely matched, enabling functional substitution only when polarity and power requirements align.
What PCB layout guidance applies to SMB10J6.0A-M3/5B for optimal surge performance?
For optimal surge performance, SMB10J6.0A-M3/5B must be mounted on minimum 5.0 mm × 5.0 mm copper pads per terminal to achieve specified thermal resistance (RθJA = 72 °C/W) and current handling. Keep traces short and wide between the device and protected node/ground plane to minimize inductance; avoid vias in the surge current path. Follow Vishay's recommended pad layout (0.205" × 0.220") to ensure mechanical reliability and thermal dissipation during repetitive surges.
