Product details
Overview
SMBJ10AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping inductive switching transients and ESD events on power and signal lines. It features 10 V standoff 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 in automotive body control modules, industrial sensor interfaces, and DC power input protection.
For engineers reviewing the SMBJ10AHE3_A/H datasheet, SMBJ10AHE3_A/H pinout, SMBJ10AHE3_A/H application, or SMBJ10AHE3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and packaging details for production-grade surge protection design.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device across DC rails or low-speed signal paths, triggering when reverse voltage exceeds its VBR threshold and limiting transient energy via low incremental surge resistance. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O pins.
The SMBJ10AHE3_A/H is rated for 600 W peak pulse power under 10/1000 µs waveform with 0.01% duty cycle, derated above 25 °C per Fig. 2, and supports 100 A non-repetitive forward surge current (IFSM) for 8.3 ms half-sine wave - confirming suitability for automotive load-dump and inductive kickback suppression where high-energy transients occur infrequently.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse operating voltage before leakage exceeds 5 µA; defines safe DC bias margin for protected line. |
| VBR (Breakdown Voltage) | 11.1–12.3 V at 1 mA - Confirmed minimum/maximum reverse breakdown threshold; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 17.0 V at 35.3 A (10/1000 µs) - Measured peak voltage across device during worst-case surge; determines maximum stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 µs transient; validates robustness against ISO 7637-2 Pulse 1/2a/5a. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on 0.2" × 0.2" copper pads; enables thermal budget calculation for PCB layout. |
| TJ max. | +150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications per stress test requirements including HTGB, HTRB, and temperature cycling. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, MSL Level 1 (260 °C peak reflow), RoHS-compliant and halogen-free compliant per base P/NHE3 designation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line; conducts surge current to ground when VREV > VBR; polarity must match circuit grounding scheme. |
| Anode | Reference/ground return path | Typically tied to system ground plane; completes conduction path during clamping; requires low-inductance layout for effective suppression. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Validates immunity to high-energy transients like ISO 16750-2 load dump without degradation over rated lifetime. |
| AEC-Q101 qualified (HE3 suffix) | Confirms reliability for automotive ECUs, ADAS sensors, and infotainment systems requiring automotive-grade component validation. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during clamping, reducing risk of latch-up or gate oxide damage in protected MOSFETs and ICs. |
| Glass-passivated junction | Ensures stable VBR tolerance and low leakage drift over temperature and life, critical for long-term field reliability. |
| MSL Level 1 moisture sensitivity | Enables standard SMT assembly without baking or special handling, reducing manufacturing cost and process complexity. |

FAQ
What is the clamping voltage of SMBJ10AHE3_A/H at its rated peak pulse current?
The SMBJ10AHE3_A/H has a maximum clamping voltage (VC) of 17.0 V at 35.3 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings. The SMBJ10AHE3_A/H maintains this clamping performance across its full operating temperature range.
Is SMBJ10AHE3_A/H qualified for automotive applications?
Yes, SMBJ10AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88392 (Revision 09-Jan-2024). This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling - validating its use in automotive body electronics, infotainment systems, and ADAS sensor modules where reliability under thermal and electrical stress is essential.
What is the standoff voltage and breakdown voltage range for SMBJ10AHE3_A/H?
The SMBJ10AHE3_A/H has a reverse standoff voltage (VWM) of 10 V and a breakdown voltage (VBR) range of 11.1 V to 12.3 V at 1 mA test current. This 1.1 V margin between VWM and minimum VBR ensures stable blocking during normal operation while guaranteeing reliable turn-on during transients - a key design parameter for selecting appropriate DC bias headroom in protected circuits.
Does SMBJ10AHE3_A/H have a bidirectional version?
No, SMBJ10AHE3_A/H is strictly unidirectional, indicated by the "A" suffix and cathode band marking. For bidirectional operation, Vishay offers SMBJ10CAHE3_A/H (with "CA" suffix), which provides symmetrical clamping in both polarities and is used in AC-coupled or floating signal line protection. The SMBJ10AHE3_A/H must be oriented correctly in-circuit with cathode toward the protected line to function as intended.
What package type and mounting specifications apply to SMBJ10AHE3_A/H?
SMBJ10AHE3_A/H uses the SMB (DO-214AA) surface-mount package with dimensions 4.57 mm × 3.94 mm × 2.20 mm and matte tin-plated leads. It meets J-STD-020 MSL Level 1 (peak reflow 260 °C), requires 0.2" × 0.2" copper pads per terminal for thermal and surge performance, and is compatible with standard automated pick-and-place and reflow processes - making it suitable for high-volume automotive and industrial manufacturing.
