Product details
Overview
SMB10J6.0AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on power and signal lines. It features a 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. It is AEC-Q101 qualified and halogen-free, targeting automotive sensor interface and power rail protection.
For engineers reviewing the SMB10J6.0AHM3_A/I datasheet, SMB10J6.0AHM3_A/I pinout, SMB10J6.0AHM3_A/I application, or SMB10J6.0AHM3_A/I equivalent, this page delivers verified electrical specs, automotive-grade qualification status, thermal resistance data, clamping performance under standardized transients, and direct alternative part comparisons - all aligned with Vishay Document #88422 (Rev. 09-Jan-2024).
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its low incremental surge resistance enables stable clamping during multi-kA surges, while MSL Level 1 moisture sensitivity supports lead-free reflow up to 260 °C peak.
The device operates across -55 °C to +150 °C junction temperature range and exhibits 72 °C/W typical junction-to-ambient thermal resistance when mounted on 5.0 mm × 5.0 mm copper pads. Its unidirectional polarity (cathode marked) ensures DC-biased line compatibility without reverse conduction during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.0 V - Maximum continuous reverse voltage before significant leakage; sets operating margin above circuit nominal voltage. |
| VBR (Breakdown Voltage) | 6.67–7.37 V at 10 mA - Confirmed voltage threshold where avalanche conduction begins; defines minimum overvoltage trip point. |
| VC (Clamping Voltage) | ≤10.3 V at IPPM - Measured maximum voltage across device during 10/1000 µs surge; determines protected IC's stress level. |
| PPPM (Peak Pulse Power) | 1000 W (10/1000 µs) - Energy-handling capacity under standard lightning surge waveform; validates robustness per IEC 61000-4-5. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0AHE3_A/I | Same VWM (6.0 V), VBR (6.67–7.37 V), and PPPM (1000 W), but commercial-grade (non-AEC-Q101) and RoHS-compliant only (not halogen-free). | Lacks automotive qualification; suitable for industrial or consumer designs where AEC-Q101 is not mandated. | Select SMBJ6.0AHE3_A/I when cost sensitivity outweighs automotive compliance requirements and halogen-free status is optional. |
| SMB10J6.0A-E3/52 | Identical electrical specs and SMB package, but RoHS-compliant commercial grade (E3 suffix) and supplied in 7" tape/reel (750 pcs) instead of 13" (3200 pcs). | No AEC-Q101 or halogen-free certification; intended for non-automotive volume production with standard packaging logistics. | Choose SMB10J6.0A-E3/52 for high-volume commercial applications requiring lowest unit cost and standard reel delivery. |
Compared with SMBJ6.0AHE3_A/I and SMB10J6.0A-E3/52, SMB10J6.0AHM3_A/I uniquely combines AEC-Q101 qualification, halogen-free construction, and 13" reel packaging - making it the only option qualified for automotive Tier-1 production with full environmental compliance and extended supply chain flexibility.

FAQ
What is the clamping voltage of SMB10J6.0AHM3_A/I at its rated peak pulse current?
The SMB10J6.0AHM3_A/I has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated 10/1000 µs peak pulse current of 97.1 A. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay Document #88422, ensuring predictable overvoltage limiting for downstream ICs. The SMB10J6.0AHM3_A/I maintains this clamping performance across its full operating temperature range.
Is SMB10J6.0AHM3_A/I qualified for automotive applications?
Yes, SMB10J6.0AHM3_A/I is AEC-Q101 qualified, as explicitly stated in Vishay Document #88422 (Rev. 09-Jan-2024). This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling - validating its suitability for under-hood and chassis-mounted automotive modules. The SMB10J6.0AHM3_A/I carries the HM3 suffix denoting halogen-free, RoHS-compliant, and AEC-Q101-qualified construction.
What is the thermal resistance of SMB10J6.0AHM3_A/I, and how does it affect layout design?
The SMB10J6.0AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard PCB layout per Vishay's recommended pad dimensions. To maintain safe junction temperatures during repetitive surges, designers must ensure adequate copper area and avoid thermal bottlenecks - the SMB10J6.0AHM3_A/I's RθJA directly informs minimum pad size and heatsinking requirements.
How does the SMB10J6.0AHM3_A/I differ from the SMBJ6.0AHE3_A/I in terms of compliance and packaging?
The SMB10J6.0AHM3_A/I is halogen-free, RoHS-compliant, and AEC-Q101 qualified (HM3 suffix), supplied in 13" tape-and-reel (3200 pcs). In contrast, SMBJ6.0AHE3_A/I is RoHS-compliant only (E3 suffix), lacks AEC-Q101 and halogen-free certification, and ships in 7" reels (750 pcs). Both share identical electrical specs, but SMB10J6.0AHM3_A/I meets stricter automotive and environmental mandates required for Tier-1 production. The SMB10J6.0AHM3_A/I is the only variant validated for both AEC-Q101 and JEDEC J-STD-201 Class 2 whisker resistance.
What is the maximum reverse leakage current of SMB10J6.0AHM3_A/I at its stand-off voltage?
At its 6.0 V stand-off voltage (VWM) and TA = 25 °C, the SMB10J6.0AHM3_A/I exhibits a maximum reverse leakage current (ID) of 1000 µA, as specified in the unidirectional electrical characteristics table of Vishay Document #88422. This low leakage ensures minimal power loss in always-on circuits and avoids false triggering of monitoring circuits - a critical parameter for battery-backed or low-quiescent-current automotive subsystems using SMB10J6.0AHM3_A/I.
