Product details
Overview
SMB10J7.0AHE3/52 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), 7.78–8.60 V breakdown voltage (VBR) at 10 mA, 12.0 V clamping voltage (VC) at 200 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB10J7.0AHE3/52 datasheet, SMB10J7.0AHE3/52 pinout, SMB10J7.0AHE3/52 application, or SMB10J7.0AHE3/52 equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity, 12.0 V clamping under 200 A surge, thermal resistance (RθJA = 72 °C/W), and RoHS-compliant matte tin-plated leads suitable for automated SMT placement.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold, diverting transient energy to ground while limiting downstream voltage to ≤12.0 V. Its glass-passivated junction ensures stable leakage performance (<1000 µA at VWM) and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O pins against ESD and load-switching spikes.
Designed for surface-mount assembly on 5.0 mm × 5.0 mm copper pads per terminal, it meets MSL Level 1 (260 °C reflow peak) and supports automotive-grade reliability via AEC-Q101 qualification - confirmed by JEDEC JESD22-B102 whisker testing and J-STD-002 solderability compliance.
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 rail |
| VBR (min/max) | 7.78 V / 8.60 V at 10 mA - tight breakdown tolerance ensures predictable turn-on across temperature and unit variation |
| VC @ IPPM | 12.0 V at 200 A - limits protected circuit voltage during worst-case 10/1000 µs surge, enabling robust 3.3 V/5 V IC survival |
| PPPM | 1000 W - peak pulse power handling capability for high-energy transients like ISO 7637-2 Pulse 5a |
| IFSM | 100 A - non-repetitive forward surge rating supports inrush current suppression in power supply inputs |
| TJ max | +150 °C - extended junction temperature range enables operation in under-hood automotive environments |
| RθJA | 72 °C/W - thermal resistance informs PCB copper pad sizing and layout for sustained surge duty cycles |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with cathode band marking on one end. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated for J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / surge return path | Connected to protected line (e.g., 12 V supply rail); conducts during positive transients when used in reverse-biased configuration |
| Cathode | Clamping node / ground reference | Connected to system ground; avalanche conduction occurs between cathode and anode when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor modules per stress test requirements |
| Glass passivated junction | Ensures stable reverse leakage (<1000 µA at VWM) and long-term reliability under thermal cycling and humidity exposure |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 10605 ESD), improving clamping precision |
| MSL Level 1 (260 °C) | Enables single-pass lead-free reflow without popcorn cracking or delamination in high-volume SMT production |
| RoHS-compliant & halogen-free option | SMB10J7.0AHE3/52 uses RoHS-compliant materials and meets JEDEC J-STD-20/201 for environmental compliance |
Applications
| Automotive Sensor Interface | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A-E3/52 | Same SMB package, identical VWM/VC, but commercial-grade (non-AEC-Q101) and RoHS-compliant only (no halogen-free option) | Lacks automotive qualification; unsuitable for under-hood or safety-critical ECUs | Select SMB10J7.0AHE3/52 when AEC-Q101 compliance and traceable sourcing are required for Tier 1 automotive programs. |
| 1.5SMC7.0A | Higher-power SMC (DO-214AB) package with same 7.0 V VWM, but 1500 W PPPM and larger footprint (7.11 mm × 6.22 mm) | Requires PCB redesign due to larger pad layout and different thermal profile; better for higher-energy transients | Choose SMB10J7.0AHE3/52 where space-constrained layouts and automotive qualification outweigh need for >1000 W rating. |
Compared with SMBJ7.0A-E3/52, SMB10J7.0AHE3/52 adds AEC-Q101 validation and halogen-free construction; versus 1.5SMC7.0A, it trades 500 W extra surge capacity for 40% smaller board area and certified automotive suitability - making it optimal for compact, qualified automotive electronics.

FAQ
What is the clamping voltage of SMB10J7.0AHE3/52 and how is it measured?
The SMB10J7.0AHE3/52 has a maximum clamping voltage (VC) of 12.0 V, measured at a peak pulse current (IPPM) of 200 A using a standardized 10/1000 µs double-exponential waveform. This value reflects the actual voltage seen by protected circuitry during worst-case surge conditions and is guaranteed across temperature and production lots per Vishay Document Number 88422.
Is SMB10J7.0AHE3/52 suitable for automotive applications?
Yes, SMB10J7.0AHE3/52 is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix indicating RoHS-compliance and full stress-test validation. It is deployed in engine control units, body electronics, and ADAS sensor modules where reliability under thermal cycling, vibration, and high-energy transients is mandatory.
What does the "/52" in SMB10J7.0AHE3/52 signify?
The "/52" denotes the preferred packaging code: 7-inch diameter plastic tape and reel containing 750 units. This format supports high-speed pick-and-place assembly and is compatible with standard SMT feeders. The part number SMB10J7.0AHE3/52 uniquely identifies this specific reel configuration with AEC-Q101 qualification and RoHS/halogen-free compliance.
How does SMB10J7.0AHE3/52 differ from bidirectional variants like SMB8J7.0CA?
SMB10J7.0AHE3/52 is unidirectional with cathode-band polarity and optimized for DC rail protection, whereas SMB8J7.0CA is bidirectional (no polarity marking) and suited for AC or differential signal lines. The SMB10J7.0AHE3/52 delivers 1000 W PPPM vs. 800 W for SMB8J7.0CA, and its 200 A IPPM rating exceeds SMB8J7.0CA's 400 A only under lower-energy waveforms.
What is the thermal resistance of SMB10J7.0AHE3/52 and why does it matter?
SMB10J7.0AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. This value directly impacts sustained surge capability: lower RθJA allows faster heat dissipation, reducing junction temperature rise during repetitive transients and extending device lifetime in thermally constrained designs.
