Product details
Overview
SMB10J7.0HE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 7.0 V stand-off voltage (VWM), 12.0 V maximum clamping voltage at 200 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 μs waveform. It is AEC-Q101 qualified and used in automotive power supply input stages.
For engineers reviewing the SMB10J7.0HE3/5B datasheet, SMB10J7.0HE3/5B pinout, SMB10J7.0HE3/5B application, or SMB10J7.0HE3/5B equivalent, key selection criteria include clamping performance under 200 A surge, unidirectional polarity for DC rail protection, AEC-Q101 qualification for automotive use, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its breakdown threshold (7.78–8.60 V at 10 mA), it avalanches to divert transient energy away from downstream ICs. Its low incremental surge resistance ensures minimal voltage overshoot during fast transients like ISO 7637-2 pulse 1 and pulse 2b.
The device uses a glass-passivated silicon junction and meets MSL Level 1 per J-STD-020 with 260 °C peak reflow tolerance. Its thermal resistance (RθJA = 72 °C/W) and junction temperature limit (TJ = 150 °C) support sustained operation in engine bay and infotainment module environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum continuous reverse operating voltage before leakage exceeds 100 μA; sets safe DC rail margin for 5 V or 12 V systems. |
| VBR min/max | 7.78 V / 8.60 V at 10 mA - Confirmed breakdown range ensures reliable triggering without premature conduction. |
| VC @ IPPM | 12.0 V at 200 A - Clamping voltage under full-rated 10/1000 μs surge; defines worst-case overvoltage seen by protected ICs. |
| PPPM | 1000 W - Peak pulse power handling capability; supports IEC 61000-4-5 Level 4 (4 kV, 2 Ω source) compliance when properly laid out. |
| ID @ VWM | 100 μA - Reverse leakage at stand-off voltage; low enough to avoid measurable power loss in battery-powered circuits. |
| TJ max | 150 °C - Maximum junction temperature; enables use in under-hood automotive locations with ambient up to 125 °C. |
| Package | DO-214AA (SMB) - Standardized surface-mount outline with 0.220" body length and cathode band marking; compatible with IPC-7351B footprint. |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, cathode indicated by a color band on one end. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or return path; forms current loop with cathode during clamping event. |
| Cathode | Protected line input | Connected to the line being protected (e.g., +12 V rail); avalanche conduction occurs from cathode to anode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including temperature cycling, mechanical shock, and humidity testing per stress test requirements. |
| Glass passivated junction | Enhances long-term reliability and moisture resistance versus epoxy-passivated alternatives; critical for under-hood durability. |
| MSL Level 1 | Zero floor life limitation; can be stored indefinitely at ≤30 °C/85 % RH and assembled without baking prior to reflow. |
| Low profile SMB package | Height ≤ 2.20 mm enables use in space-constrained modules such as ADAS camera ECUs and body control units. |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance; eliminates tin whisker risk in high-reliability automotive electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0AHE3/5B | Same electrical specs (VWM = 7.0 V, VC = 12.0 V), identical DO-214AA package, but marked "SMBJ" instead of "SMB10"; functionally interchangeable. | No difference - both qualified to AEC-Q101 and rated for 1000 W PPPM; same thermal and mounting behavior. | Select SMBJ7.0AHE3/5B if standard SMBJ family sourcing simplifies BOM consolidation across multiple voltage grades. |
| 1.5SMC7.0AHE3/A | Higher package thermal resistance (RθJA ≈ 110 °C/W vs. 72 °C/W); same VWM and VC but lower surge current rating (167 A vs. 200 A). | Less suitable for high-temperature or high-duty-cycle surge environments; requires larger PCB copper area for thermal management. | Choose only if existing 1.5SMC footprint reuse is mandatory; otherwise SMB10J7.0HE3/5B offers superior thermal performance and surge margin. |
Compared with SMBJ7.0AHE3/5B, SMB10J7.0HE3/5B offers identical protection performance in the same footprint but reflects Vishay's updated part numbering convention; versus 1.5SMC7.0AHE3/A, it delivers 20 % higher surge current capacity and 35 % lower thermal resistance-critical for automotive under-hood reliability.

FAQ
What is the clamping voltage of SMB10J7.0HE3/5B at its rated peak pulse current?
The SMB10J7.0HE3/5B has a maximum clamping voltage (VC) of 12.0 V when subjected to its rated peak pulse current of 200 A using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 12-Nov-12, ensuring predictable overvoltage limiting for protected circuitry.
Is SMB10J7.0HE3/5B suitable for automotive applications?
Yes, SMB10J7.0HE3/5B is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junction, MSL Level 1 moisture sensitivity, and JESD 201 Class 2 whisker resistance-all validated per automotive stress test standards. The SMB10J7.0HE3/5B is deployed in body control modules, infotainment power supplies, and ADAS sensor interfaces.
What does the "HE3" suffix indicate in SMB10J7.0HE3/5B?
The "HE3" suffix in SMB10J7.0HE3/5B denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this grade from commercial-only "E3" variants and confirms suitability for high-reliability automotive and industrial applications where long-term tin whisker mitigation is required.
How does SMB10J7.0HE3/5B differ from SMBJ7.0AHE3/5B?
SMB10J7.0HE3/5B and SMBJ7.0AHE3/5B share identical electrical specifications (VWM = 7.0 V, VBR = 7.78–8.60 V, VC = 12.0 V), DO-214AA package dimensions, and AEC-Q101 qualification. The difference is purely nomenclatural: "SMB10J" reflects Vishay's updated naming convention, while "SMBJ" is the legacy prefix. Both are functionally interchangeable in design and layout.
What PCB pad layout is required to achieve the full 1000 W rating of SMB10J7.0HE3/5B?
To achieve the full 1000 W peak pulse power rating, SMB10J7.0HE3/5B must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. Smaller pads result in thermal derating per Figure 2, reducing sustainable surge current and requiring layout validation for target transient profiles.
