Product details
Overview
SMB10J7.0AHE3_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 DC power rails and signal lines. It features a 7.0 V stand-off voltage (VWM), 12.0 V maximum clamping voltage (VC) at 200 A peak pulse current (IPPM), and 1000 W peak pulse power (10/1000 µs waveform), making it suitable for automotive power line and industrial sensor interface protection.
For engineers reviewing the SMB10J7.0AHE3_A/I datasheet, SMB10J7.0AHE3_A/I pinout, SMB10J7.0AHE3_A/I application, or SMB10J7.0AHE3_A/I equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity with cathode band marking, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a silicon avalanche diode that enters breakdown when reverse voltage exceeds its 7.78–8.60 V breakdown range (VBR at 10 mA), clamping transients to ≤12.0 V while absorbing up to 1000 W of surge energy. Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and fast response time (<1 ns).
Thermally, it supports operation from −55 °C to +150 °C with RθJA = 72 °C/W (on 0.2" × 0.2" pads) and RθJL = 20 °C/W, enabling reliable performance under repetitive surge stress in automotive ECUs and industrial PLC I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum continuous reverse operating voltage before clamping begins; sets safe margin above 5 V or 6.5 V nominal rails. |
| VBR (min/max) | 7.78 V / 8.60 V at 10 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 12.0 V at 200 A (10/1000 µs) - Clamped voltage seen by protected circuit; limits stress on downstream MOSFETs or ICs. |
| PPPM | 1000 W - Peak surge power handling capability; supports ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 compliance. |
| IFSM | 100 A (8.3 ms half-sine) - Forward surge rating; enables use in DC power input stages subject to load dump. |
| TJ max | +150 °C - Junction temperature limit; allows deployment in under-hood automotive environments without derating. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD per JESD22 standards. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Cathode indicated by color band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side connection | Connected to ground or lower-potential rail; forms return path during clamping. |
| Cathode | Reverse-biased terminal / high-side connection | Connected to protected line (e.g., 12 V supply); avalanche conduction occurs here during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics including engine control, body modules, and ADAS sensors. |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage (<1000 µA at VWM) across temperature and lifetime. |
| Low profile SMB package | Enables high-density PCB layouts and compatibility with standard SMT pick-and-place equipment. |
| MSL Level 1 (260 °C peak) | Supports lead-free reflow without moisture sensitivity concerns; no baking required pre-assembly. |
| 1000 W peak pulse power | Provides robust protection against severe transients such as load dump (ISO 7637-2 Pulse 5a) in 12 V systems. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and jump-start surges per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp transients within 1 ns.

Use Scenario: Securing PoE-powered Ethernet ports against lightning-induced surges and AC mains coupling. IC Role / Device Role / Timing Role: Primary-level TVS on DC input side of isolated DC/DC converter feeding PHY and MAC. Use Value: Withstands 1000 W pulses and meets IEC 61000-4-5 Level 4 (4 kV/2 kA), reducing need for secondary protection stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0AHE3_A/I | Same VWM (7.0 V), identical SMB package, but rated for 600 W PPPM (vs. 1000 W). | Limited to lower-energy transients (e.g., ESD, contact discharge); insufficient for ISO 7637-2 Pulse 5a. | Select when cost optimization is prioritized and surge threat level is below 600 W. |
| SMCJ7.0AHE3_A/I | Same electrical specs but in larger SMC (DO-214AB) package with higher thermal mass and 1500 W PPPM. | Better suited for high-repetition surge environments or where board space permits larger footprint. | Choose when enhanced thermal endurance or margin beyond 1000 W is required. |

Yes, SMB10J7.0AHE3_A/I is AEC-Q101 qualified and manufactured with automotive-grade process controls, including HTOL, temperature cycling, and ESD testing. Its 1000 W surge rating, −55 °C to +150 °C operating range, and MSL Level 1 rating make it appropriate for under-hood and cabin ECU applications where the SMB10J7.0AHE3_A/I is deployed for power rail protection.
What does the "HE3" suffix indicate in SMB10J7.0AHE3_A/I?
The "HE3" suffix in SMB10J7.0AHE3_A/I denotes RoHS-compliant construction with AEC-Q101 qualification and halogen-free molding compound. The "_A/I" indicates packaging in 13-inch tape-and-reel (3200 units) with revision code A, conforming to Vishay's automotive ordering nomenclature for traceable, high-reliability supply chains.
How does SMB10J7.0AHE3_A/I compare to bidirectional TVS diodes like SMB8J7.0CA?
The SMB10J7.0AHE3_A/I is unidirectional and optimized for DC rail protection with 1000 W rating, while SMB8J7.0CA is bidirectional (symmetrical clamping) rated at 800 W. The SMB10J7.0AHE3_A/I provides superior surge capacity for single-polarity systems and includes a visible cathode band for polarity verification-critical for correct orientation in power supply designs using the SMB10J7.0AHE3_A/I.
What is the maximum clamping voltage of SMB10J7.0AHE3_A/I at rated surge current?
The SMB10J7.0AHE3_A/I clamps to a maximum of 12.0 V at its rated peak pulse current of 200 A (10/1000 µs waveform), as specified in Vishay's Document Number 88422.
