Product details
Overview
SMB10J6.0AHM3/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 DC power rails and signal lines. It features a 6.0 V stand-off voltage (VWM), 1000 W peak pulse power (10/1000 µs), 10.3 V clamping voltage at 97.1 A peak surge current, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMB10J6.0AHM3/I datasheet, SMB10J6.0AHM3/I pinout, SMB10J6.0AHM3/I application, or SMB10J6.0AHM3/I equivalent, key selection criteria include clamping performance under 100 A surge, thermal resistance (RθJA = 72 °C/W), unidirectional polarity with cathode band marking, and halogen-free RoHS-compliant construction per HM3 suffix.
Technical Context
This TVS diode operates as a clamping-type overvoltage protector, leveraging an avalanche breakdown mechanism to limit transient voltages before they damage downstream ICs or MOSFETs. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1000 µA at VWM), while its MSL Level 1 rating supports lead-free reflow up to 260 °C.
The device is optimized for fast response (<1 ns) to ESD and lightning-induced transients, with low incremental surge resistance enabling tight clamping. Its 150 °C maximum junction temperature and derating curve (Fig. 2) support reliable operation in under-hood automotive environments and industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before conduction begins; sets minimum system rail margin. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown threshold range; ensures predictable turn-on during transients. |
| VC @ IPPM | 10.3 V at 97.1 A - Clamped voltage during 1000 W surge; defines worst-case stress on protected circuitry. |
| PPPM | 1000 W (10/1000 µs) - Peak surge energy handling capacity; validates robustness against ISO 7637-2 Pulse 1/2a/5a. |
| IFSM | 100 A (8.3 ms half-sine) - Forward surge rating; supports protection of rectifier stages and DC input filters. |
| TJ max | +150 °C - Maximum junction temperature; enables deployment in engine control units and motor drives. |
| RθJA | 72 °C/W - Thermal resistance junction-to-ambient on 5.0 mm × 5.0 mm copper pads; informs board-level thermal design. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by color band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMB10J6.0AHE3_B/I | RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification. | Suitable for commercial-grade consumer or computing applications only. | Select when automotive qualification is unnecessary and cost sensitivity outweighs halogen-free requirement. |
| SMBJ6.0A-M3/5B | Same SMB package and electrical specs, but base P/N uses different suffix convention and reel packaging (13" vs. 7"). | No functional difference; identical performance and qualification level (HM3 equivalent). | Choose based on preferred tape-and-reel logistics-same device, alternate ordering code. |
Compared with SMB10J6.0AHM3/I, the HE3 variant omits halogen-free and AEC-Q101 compliance, limiting automotive use, while SMBJ6.0A-M3/5B is functionally identical but differs only in packaging format and orderable part number structure.

FAQ
What is the clamping voltage of SMB10J6.0AHM3/I at its rated peak pulse current?
The SMB10J6.0AHM3/I has a maximum clamping voltage (VC) of 10.3 V when subjected to its peak pulse current (IPPM) of 97.1 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during worst-case surge events. The SMB10J6.0AHM3/I maintains this clamping performance across its full operating temperature range.
Is SMB10J6.0AHM3/I suitable for automotive applications?
Yes, SMB10J6.0AHM3/I is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials (HM3 suffix), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor modules. Its 150 °C maximum junction temperature, MSL Level 1 rating, and validated surge performance per ISO 7637-2 confirm its readiness for under-hood and chassis-mounted deployments.
What does the "HM3" suffix indicate in SMB10J6.0AHM3/I?
The "HM3" suffix in SMB10J6.0AHM3/I denotes halogen-free, RoHS-compliant construction meeting JEDEC JESD201 Class 2 whisker resistance requirements. It also signifies AEC-Q101 qualification and packaging in 13-inch tape-and-reel (I-code). This distinguishes it from E3 (RoHS only) and HE3 (RoHS + AEC-Q101, but not halogen-free) variants of the same device.
How does SMB10J6.0AHM3/I differ from SMBJ6.0A?
SMB10J6.0AHM3/I and SMBJ6.0A share identical electrical specifications, package (SMB/DO-214AA), and surge ratings, but differ in ordering nomenclature and qualification. SMB10J6.0AHM3/I explicitly carries HM3 suffix confirming halogen-free + AEC-Q101 status, whereas SMBJ6.0A-M3/5B uses alternate suffixing and reel size. Both are functionally interchangeable when HM3 compliance is verified in the bill of materials.
What is the thermal resistance of SMB10J6.0AHM3/I, and how does it affect PCB layout?
The SMB10J6.0AHM3/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. To maintain safe junction temperatures under repeated surges, PCB layout must provide at least this pad area for each terminal, with internal ground/power planes recommended for enhanced heat spreading. Reduced copper area increases RθJA, risking thermal runaway during high-duty-cycle transients.
