Product details
Overview
SMB10J7.0HE3/52 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 (IPPM), and 1000 W peak pulse power rating with 10/1000 μs waveform. Used in automotive power supply inputs to protect microcontrollers and CAN transceivers against load dump and ISO 7637-2 pulses.
For engineers reviewing the SMB10J7.0HE3/52 datasheet, SMB10J7.0HE3/52 pinout, SMB10J7.0HE3/52 application, or SMB10J7.0HE3/52 equivalent, key selection criteria include clamping performance under 200 A surge, AEC-Q101 qualification for automotive use, RoHS-compliant HE3 suffix with JESD 201 Class 2 whisker resistance, and thermal resistance (RθJA = 72 °C/W) for PCB layout validation.
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 limit transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable leakage (<1000 μA at 7.0 V) and fast response (<1 ns), critical for protecting sensitive 3.3 V/5 V logic interfaces.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Fig. 2; its 20 °C/W junction-to-lead thermal resistance supports solder-pad thermal management on 5.0 mm × 5.0 mm copper pads. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - mandatory for under-hood automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum continuous reverse operating voltage before conduction; sets minimum system rail margin for reliable standby operation. |
| VBR min/max | 7.78 V / 8.60 V at 10 mA - Tight breakdown window ensures predictable turn-on without premature clamping during normal transients. |
| VC @ IPPM | 12.0 V at 200 A (10/1000 μs) - Clamping voltage defines worst-case stress on downstream ICs; enables robust protection of 12 V automotive electronics. |
| PPPM | 1000 W - Peak pulse power handling capacity determines survivability against ISO 7637-2 Pulse 5a (load dump) events. |
| ID @ VWM | <1000 μA - Low leakage preserves battery life in always-on automotive modules and avoids false triggering in high-impedance sensor circuits. |
| TJ max | 150 °C - Enables operation in engine control units (ECUs) and body control modules exposed to under-hood thermal environments. |
| RθJA | 72 °C/W - Guides minimum copper pad area (0.2" × 0.2") required to maintain junction temperature within spec under sustained surges. |
Pinout & Package
DO-214AA (SMB) surface-mount package with cathode band marking on one end; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-impedance return path; establishes clamping reference for protected line. |
| Cathode | Protected line input | Connected to power rail or signal line requiring surge suppression; avalanche conduction occurs from cathode to anode during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - required for ECU, ADAS, and infotainment systems. |

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 VWM (7.0 V), same DO-214AA package, but rated for 600 W PPPM (vs. 1000 W) and 100 A IPPM (vs. 200 A). | Limited to lower-energy transients (e.g., IEC 61000-4-5 Level 3); unsuitable for automotive load dump where 1000 W is required. | Select SMB10J7.0HE3/52 when full ISO 7637-2 compliance is mandatory; SMBJ7.0A-E3/52 suffices for consumer-grade surge immunity. |
| 1.5SMC7.0A | Same VWM and clamping (12.0 V), but larger DO-214AB (SMC) package (2.54 mm pitch vs. 2.29 mm), higher RθJA (50 °C/W), and no AEC-Q101 qualification. | Requires larger PCB footprint and lacks automotive qualification; suitable for industrial power supplies but not under-hood ECUs. | Choose SMB10J7.0HE3/52 for space-constrained automotive designs needing AEC-Q101; 1.5SMC7.0A fits cost-sensitive industrial applications with relaxed qualification needs. |
Compared with SMBJ7.0A-E3/52 and 1.5SMC7.0A, SMB10J7.0HE3/52 uniquely delivers 1000 W surge capability in a compact AEC-Q101-qualified SMB package - enabling smaller, more robust protection for automotive and high-reliability industrial power rails without layout or qualification compromises.

FAQ
What is the clamping voltage of SMB10J7.0HE3/52 at its rated peak pulse current?
The SMB10J7.0HE3/52 has a maximum clamping voltage (VC) of 12.0 V when subjected to its rated peak pulse current of 200 A with a 10/1000 μs waveform. This value is measured under standardized test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events. The SMB10J7.0HE3/52 maintains this clamping performance consistently due to its glass-passivated junction and low incremental surge resistance.
Is SMB10J7.0HE3/52 qualified for automotive applications?
Yes, SMB10J7.0HE3/52 is AEC-Q101 qualified, as confirmed by Vishay's documentation and the HE3 suffix designation. This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock - validating its suitability for under-hood and chassis-mounted automotive modules. The SMB10J7.0HE3/52 meets the reliability requirements for engine control units, body control modules, and ADAS sensors where sustained operation at 150 °C junction temperature is required.
How does the HE3 suffix differ from E3 in SMB10J7.0HE3/52?
The HE3 suffix in SMB10J7.0HE3/52 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 denotes RoHS compliance only (commercial grade). The HE3 variant undergoes additional automotive-specific reliability testing and uses enhanced plating to resist tin whisker growth under thermal cycling - critical for long-life automotive deployments. For non-automotive applications, SMB10J7.0A-E3/52 may be used, but SMB10J7.0HE3/52 is mandatory where AEC-Q101 is specified.
What is the maximum reverse leakage current of SMB10J7.0HE3/52 at its stand-off voltage?
The SMB10J7.0HE3/52 exhibits a maximum reverse leakage current (ID) of 1000 μA at its 7.0 V stand-off voltage (VWM), measured at TA = 25 °C. This low leakage ensures minimal power loss in always-on automotive subsystems and avoids false triggering in high-impedance sensor signal paths. The SMB10J7.0HE3/52 maintains this specification across its full operating temperature range (-55 °C to +150 °C), with leakage increasing predictably per datasheet derating curves.
Can SMB10J7.0HE3/52 be used in bi-directional protection configurations?
No, SMB10J7.0HE3/52 is a unidirectional TVS diode, as indicated by its part number suffix "A" and absence of "C" (which denotes bi-directional variants like SMB8J7.0CA). Its cathode band marking and electrical characteristics - including forward voltage drop and asymmetric breakdown behavior - are optimized for single-polarity clamping on positive rails. For bi-directional protection (e.g., AC signal lines or RS-485 buses), SMB8J7.0CA or equivalent bidirectional devices must be selected instead of SMB10J7.0HE3/52.
