Product details
Overview
SMBJ10HE3/52 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed on power rails and signal lines in industrial sensor interfaces.
For engineers reviewing the SMBJ10HE3/52 datasheet, SMBJ10HE3/52 pinout, SMBJ10HE3/52 application, or SMBJ10HE3/52 equivalent, this device is selected for high-reliability transient suppression where AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.53), and MSL Level 1 moisture sensitivity are critical design requirements.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, leveraging a glass-passivated silicon junction to deliver sub-nanosecond response to ESD and surge transients. Its thermal resistance (RθJA = 100 °C/W) and junction temperature limit (TJ = 150 °C) support operation under repetitive surge conditions when mounted on 5.0 mm × 5.0 mm copper pads.
The SMBJ10HE3/52 variant is AEC-Q101 qualified and RoHS-compliant, with matte tin-plated leads meeting J-STD-002 solderability and JESD 22-B102 whisker resistance Class 2. Polarity is marked by a cathode band; no marking applies to bidirectional versions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin for protected line. |
| VBR (min/max) | 11.1 V / 12.3 V at IT = 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 17.0 V at 35.3 A - Clamped voltage during 600 W 10/1000 µs surge; limits downstream IC stress to safe levels. |
| PPPM | 600 W - Peak pulse power handling capability; supports IEC 61000-4-5 Level 4 surge immunity testing. |
| IPPM | 35.3 A - Peak surge current capacity with 10/1000 µs waveform; enables protection of 24 V industrial buses. |
| TJ max. | 150 °C - Maximum junction temperature; allows operation in under-hood automotive or enclosed industrial enclosures. |

Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; polarity indicated by cathode band on the body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-impedance return path; completes clamping loop during transient events. |
| Cathode | High-side connection point | Connected to protected line (e.g., 12 V rail or RS-485 bus); conducts avalanche current when VIN exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per JESD47. |
| 600 W peak pulse power (10/1000 µs) | Enables single-device protection against IEC 61000-4-5 4 kV surge on 50 Ω source impedance lines. |
| Clamping ratio VC/VBR ≈ 1.53 | Minimizes voltage overshoot during clamping; reduces risk of latch-up or gate oxide damage in downstream MOSFETs. |
| MSL Level 1 (260 °C peak) | Allows standard lead-free reflow without baking; eliminates pre-conditioning delays in high-volume SMT production. |
| Glass-passivated junction | Provides stable leakage performance (<1 µA at VWM) and long-term stability under thermal cycling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-E3/52 | Commercial-grade (non-AEC-Q101), identical electrical specs and SMB package. | Lacks automotive qualification; suitable for industrial/commercial designs without automotive lifecycle or reliability mandates. | Select when AEC-Q101 is not required and cost optimization is prioritized. |
| SAC10 | Same VWM (10 V), but lower PPPM (400 W) and higher VC (20 V); SOD-123FL package (smaller footprint). | Lower surge margin; limited to low-energy transients (e.g., ESD-only) in space-constrained consumer PCBs. | Choose only for non-automotive, low-surge environments where board area is critical and 600 W headroom is unnecessary. |
Compared with SMBJ10A-E3/52, the SMBJ10HE3/52 adds AEC-Q101 validation and extended temperature reliability; versus SAC10, it delivers 50 % higher surge energy handling and lower clamping voltage in a larger but more thermally robust SMB package.

FAQ
What is the clamping voltage of SMBJ10HE3/52 at its rated peak pulse current?
The SMBJ10HE3/52 has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 35.3 A, measured using the standardized 10/1000 µs double-exponential surge waveform. This value is confirmed in the Vishay datasheet Document Number 88392, page 2, Electrical Characteristics table. The low clamping ratio ensures effective protection of downstream 12 V logic and interface ICs without overstressing their absolute maximum ratings.
Is SMBJ10HE3/52 suitable for automotive applications?
Yes, SMBJ10HE3/52 is AEC-Q101 qualified and explicitly designated for automotive use, as indicated by the "HE3" suffix per Vishay's ordering nomenclature. It meets automotive reliability requirements including temperature cycling, high-temperature reverse bias, and surge endurance testing. The SMBJ10HE3/52 is commonly used in body control modules, infotainment power supplies, and LIN/CAN node protection where sustained operation up to 150 °C junction temperature is required.
What is the standoff voltage (VWM) and why does it matter for SMBJ10HE3/52?
The standoff voltage (VWM) of SMBJ10HE3/52 is 10 V - the maximum continuous reverse voltage the device can block without entering avalanche conduction. This parameter ensures the SMBJ10HE3/52 remains non-conductive during normal operation on a 12 V nominal system, minimizing leakage (<1 µA at 25 °C) and avoiding false triggering. Selecting VWM ≥ 1.1× nominal line voltage prevents nuisance conduction while preserving sufficient margin for ripple and tolerance.
How does the SMBJ10HE3/52 package compare to SMA or SMC variants?
The SMBJ10HE3/52 uses the SMB (DO-214AA) package - measuring 4.06 mm × 5.59 mm - which offers higher power dissipation than SMA (DO-214AC) and smaller footprint than SMC (DO-214AB). Compared to SMA, SMB provides ~25 % higher thermal mass and 600 W pulse rating versus typical 400 W for SMA equivalents. Unlike SMC, SMB maintains compatibility with standard 8 mm tape-and-reel feeders and requires less PCB area, making it optimal for mid-power automotive and industrial protection where space and surge margin are balanced.
Can SMBJ10HE3/52 be used in bidirectional configurations?
No, SMBJ10HE3/52 is a unidirectional TVS diode, as confirmed by its part number suffix "A" and cathode-band marking. Bidirectional operation requires the "CA" suffix (e.g., SMBJ10CA), which internally connects two opposing diodes. Using SMBJ10HE3/52 in reverse-biased configurations risks permanent junction damage during positive transients. For AC-coupled or differential signal lines requiring symmetrical clamping, SMBJ10CA-E3/52 or equivalent bidirectional variant must be selected instead.
