Product details
Overview
SMBJ10AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features 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 (IPPM), and 600 W peak pulse power (10/1000 µs waveform). It protects MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom line cards.
For engineers reviewing the SMBJ10AHE3/5B datasheet, SMBJ10AHE3/5B pinout, SMBJ10AHE3/5B application, or SMBJ10AHE3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, clamping performance under 10/1000 µs surge, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a fast-acting shunt protector: under normal bias it presents high impedance (>1 MΩ leakage at 10 V), but triggers into low-impedance conduction when reverse voltage exceeds VBR (11.1–12.3 V), clamping transient energy to ≤17.0 V at 35.3 A. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Designed for single-polarity DC rail protection, SMBJ10AHE3/5B supports repetitive surge duty cycles up to 0.01 % and withstands 100 A non-repetitive forward surge (8.3 ms half-sine). It meets J-STD-020 MSL Level 1 (260 °C reflow peak) and is qualified to AEC-Q101 for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin for 12 V systems. |
| VBR (min/max) | 11.1 V / 12.3 V at 1 mA - Confirmed breakdown range ensures reliable triggering without premature conduction. |
| VC @ IPPM | 17.0 V at 35.3 A (10/1000 µs) - Clamping voltage limits downstream device stress during standardized lightning/surge events. |
| PPPM | 600 W - Peak pulse power handling capability per IEC 61000-4-5 surge standard waveform. |
| ID @ VWM | 5.0 µA max - Low reverse leakage preserves efficiency in battery-powered or low-power sensor circuits. |
| TJ max. | +150 °C - Enables operation in under-hood automotive or high-ambient industrial environments. |
| RθJA | 100 °C/W - Thermal resistance determines required PCB copper area (0.2" × 0.2" pads per terminal) for 5.0 W steady-state dissipation. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified (HE3 suffix). Cathode indicated by band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VREV > VBR. |
| Anode (unbanded end) | Reference node | Typically tied to system ground or low-impedance return path; completes clamping loop. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements (HTOL, TC, HTRB, etc.), enabling use in ADAS and body control modules. |
| 600 W peak pulse power (10/1000 µs) | Meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and telecom infrastructure. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage exposure to downstream ICs-critical for protecting 12 V logic rails and gate drivers. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns or baking requirements. |
| Glass passivated junction | Ensures stable VBR over temperature and lifetime, reducing parameter drift in harsh thermal cycling environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10AHM3/5B | Halogen-free variant with identical electrical specs and AEC-Q101 qualification. | No functional difference; selected where halogen-free compliance is mandated (e.g., EU automotive Tier 1). | Direct material substitution when RoHS + halogen-free certification is required. |
| SMBJ10A-E3/5B | Commercial-grade (non-AEC-Q101) version; same VWM, VBR, VC, PPPM, and package. | Limited to non-automotive applications (e.g., consumer power adapters, office equipment). | Cost-optimized alternative where automotive qualification is unnecessary. |
Compared with SMBJ10AHE3/5B, SMBJ10AHM3/5B adds halogen-free compliance without altering surge performance, while SMBJ10A-E3/5B removes AEC-Q101 validation-making it suitable only for commercial environments where extended temperature and reliability testing are not required.

FAQ
What is the clamping voltage of SMBJ10AHE3/5B at its rated peak pulse current?
The SMBJ10AHE3/5B has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current (IPPM) of 35.3 A under the standard 10/1000 µs waveform. This value is measured at the device terminals with specified PCB pad layout (0.2" × 0.2" copper per terminal), ensuring consistent surge suppression performance in production designs.
Is SMBJ10AHE3/5B suitable for automotive applications?
Yes, SMBJ10AHE3/5B is AEC-Q101 qualified, meaning it has passed rigorous stress tests including high-temperature operating life, temperature cycling, and humidity testing required for automotive electronics. Its +150 °C maximum junction temperature and MSL Level 1 rating make it appropriate for under-hood and body-control module applications.
How does the HE3 suffix affect the specifications of SMBJ10AHE3/5B?
HE3 denotes RoHS-compliant and AEC-Q101 qualified construction. It does not alter electrical parameters-VWM, VBR, VC, PPPM, and thermal characteristics remain identical to non-HE3 variants-but confirms compliance with automotive reliability and environmental standards. The "5B" denotes 13-inch tape-and-reel packaging (3200 units per reel).
What is the reverse leakage current of SMBJ10AHE3/5B at its stand-off voltage?
At the 10 V stand-off voltage (VWM), SMBJ10AHE3/5B exhibits a maximum reverse leakage current (ID) of 5.0 µA at 25 °C. This low leakage preserves system efficiency and avoids false triggering in high-impedance sensing or battery-backed circuits where standby current is critical.
Can SMBJ10AHE3/5B be used in bidirectional signal line protection?
No-SMBJ10AHE3/5B is unidirectional. For bidirectional protection (e.g., RS-485, USB, or AC-coupled data lines), the bidirectional variant SMBJ10CA must be used. Using SMBJ10AHE3/5B on bidirectional signals would block one polarity and fail to clamp reverse transients, risking circuit damage.
