Product details
Overview
SMB10J6.0AHE3/52 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 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1000 W peak pulse power (10/1000 µs), 97.1 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge. It is AEC-Q101 qualified and used in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMB10J6.0AHE3/52 datasheet, SMB10J6.0AHE3/52 pinout, SMB10J6.0AHE3/52 application, or SMB10J6.0AHE3/52 equivalent, key selection criteria include clamping voltage under 10.3 V at 97.1 A, unidirectional polarity with cathode band marking, AEC-Q101 qualification for automotive use, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by transient overvoltage events - such as load dump or ESD - and diverts surge current away from protected circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1000 µA at VWM), while its low incremental surge resistance enables rapid energy dissipation without thermal runaway.
The SMB10J6.0AHE3/52 is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and exhibits typical thermal resistance of 20 °C/W (junction-to-lead), enabling reliable operation under repeated surge conditions when mounted per recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below system rail. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Tight breakdown tolerance ensures predictable turn-on across production lots. |
| VC @ IPPM | ≤10.3 V at 97.1 A - Clamping voltage limits stress on downstream ICs during 10/1000 µs transients. |
| PPPM | 1000 W (10/1000 µs) - High power handling supports robust protection against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | ≤1000 µA - Low leakage preserves battery life and avoids false triggering in low-power circuits. |
| TJ max | +150 °C - Enables use in under-hood automotive environments and thermally constrained PCB layouts. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control, body electronics, and ADAS sensors. |
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 |
|---|---|---|
| Anode | Forward conduction path | Connected to lower-potential side (e.g., ground or return); conducts during forward surge or bias. |
| Cathode | Reverse-biased clamping node | Connected to protected line (e.g., 6 V rail); avalanche breakdown occurs here during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over temperature and lifetime, minimizing parameter drift in harsh environments. |
| AEC-Q101 qualification | Validates reliability for automotive applications including 1000+ temperature cycles and humidity exposure. |
| MSL Level 1 rating | Supports standard SMT reflow profiles up to 260 °C peak without preconditioning or baking. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Delivers superior protection margin versus competing TVS devices with higher VC relative to VBR. |
| Unidirectional polarity | Enables precise placement on DC rails where reverse conduction must be blocked during normal operation. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface 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 |
|---|---|---|---|
| SMBJ6.0A-E3/52 | Same SMB package and VWM (6.0 V), but rated for 600 W PPPM (vs. 1000 W) and 62.7 A IPPM. | Limited to lower-energy transients (e.g., IEC 61000-4-2 only); insufficient for IEC 61000-4-5 Level 3+. | Select SMBJ6.0A-E3/52 only if system-level surge testing requires ≤600 W capability and cost is prioritized. |
| SMAJ6.0AHE3/A | SMA (DO-214AC) package, smaller footprint (3.5 mm × 4.5 mm), same VWM and VBR, but 400 W PPPM and 39.4 A IPPM. | Lower power handling and reduced thermal mass limit use to space-constrained consumer ports or low-risk signal lines. | Choose SMAJ6.0AHE3/A only when board area is critical and surge threat level is limited to ESD or minor switching noise. |
Compared with SMBJ6.0A-E3/52 and SMAJ6.0AHE3/A, SMB10J6.0AHE3/52 delivers 67% higher peak pulse power and 55% higher clamping current capacity in the same SMB footprint - making it the only option among the three qualified for AEC-Q101 and rated for full automotive load-dump immunity.

FAQ
What is the clamping voltage of SMB10J6.0AHE3/52 at its rated peak pulse current?
The SMB10J6.0AHE3/52 clamps to a maximum of 10.3 V at its rated peak pulse current of 97.1 A (10/1000 µs waveform). This value is measured under standardized test conditions per ANSI/IEEE C62.35 and guarantees protection headroom for 6 V logic and interface ICs. The SMB10J6.0AHE3/52 maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMB10J6.0AHE3/52 suitable for automotive applications?
Yes, SMB10J6.0AHE3/52 is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix. It has passed stress tests including temperature cycling, humidity bias, and mechanical shock required for under-hood and chassis-mounted modules. The SMB10J6.0AHE3/52 is commonly deployed in engine control units, body control modules, and ADAS camera power supplies.
What does the "HE3" suffix mean in SMB10J6.0AHE3/52?
The "HE3" suffix in SMB10J6.0AHE3/52 indicates RoHS-compliant construction and AEC-Q101 qualification. It distinguishes this variant from commercial-grade versions (e.g., "E3") and confirms compliance with automotive reliability standards, including extended temperature operation and enhanced process controls. The SMB10J6.0AHE3/52 is supplied in 7″ tape-and-reel (52) packaging optimized for SMT assembly.
How does SMB10J6.0AHE3/52 differ from bidirectional TVS diodes like SMB8J6.0CA?
The SMB10J6.0AHE3/52 is unidirectional and intended for DC rail protection where reverse conduction must be blocked; SMB8J6.0CA is bidirectional and suited for AC or dual-polarity signal lines. The SMB10J6.0AHE3/52 offers 1000 W peak pulse power, while SMB8J6.0CA provides 800 W. Both share identical VWM (6.0 V) and VBR range, but only SMB10J6.0AHE3/52 supports 100 A IFSM for forward surge events.
What is the thermal resistance of SMB10J6.0AHE3/52, and how does it affect layout?
The SMB10J6.0AHE3/52 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer to PCB copper. For optimal thermal performance, Vishay specifies mounting on 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per terminal. This layout allows the SMB10J6.0AHE3/52 to sustain repeated 1000 W surges without exceeding its 150 °C maximum junction temperature.
