Product details
Overview
SMBJ130AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 130 V stand-off voltage (VWM), 144–159 V breakdown voltage (VBR) at 1 mA, 209 V maximum clamping voltage (VC) at 2.9 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 motor drives and automotive ECUs.
For engineers reviewing the SMBJ130AHE3_B/I datasheet, SMBJ130AHE3_B/I pinout, SMBJ130AHE3_B/I application, or SMBJ130AHE3_B/I equivalent, this device is selected for high-energy surge immunity in 12–48 V DC systems where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.45), and AEC-Q101 qualification are required for reliability-critical interfaces.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response to 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 SMBJ130AHE3_B/I complies with ANSI/IEEE C62.35 surge standards and delivers 2.9 A peak pulse current (IPPM) at VC = 209 V under 10/1000 µs waveform, with <1.0 µA reverse leakage at VWM = 130 V and temperature coefficient of VBR = 0.108 %/°C - enabling stable clamping across automotive and industrial ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - Maximum continuous reverse operating voltage before significant leakage; defines system operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 144–159 V at IT = 1 mA - Confirmed breakdown range ensuring reliable turn-on during surges without premature conduction. |
| VC (Clamping Voltage) | 209 V at IPPM = 2.9 A - Peak voltage seen by protected circuit during 10/1000 µs surge; determines downstream component stress level. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability per single transient event; enables protection against IEC 61000-4-5 Level 4 surges. |
| IPPM (Peak Pulse Current) | 2.9 A - Maximum surge current handled at rated VC; validates compatibility with typical 12–48 V bus fault currents. |
| TJmax | 150 °C - Maximum junction temperature supporting extended operation in engine bay or industrial enclosures without derating. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with automated pick-and-place. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, MSL Level 1 (JEDEC J-STD-020), RoHS-compliant and AEC-Q101 qualified. Polarity indicated by cathode band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-impedance return plane; completes clamping loop during positive transients on cathode side. |
| Cathode | Protected line connection | Connected to the line being protected (e.g., 130 V rail); conducts surge current to anode when VAK exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock - suitable for ECU, ADAS, and body control modules. |
| 600 W peak pulse power (10/1000 µs) | Enables single-device protection against high-energy transients per IEC 61000-4-5, eliminating need for cascaded TVS or external current limiting. |
| Glass passivated junction | Ensures stable VBR and low leakage (<1 µA) over lifetime and temperature; prevents parameter drift in humid or thermally cycled environments. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during clamping - critical for safeguarding 150 V-rated MOSFETs and gate drivers in motor inverters. |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free PCB assembly without pre-baking or special handling; reduces manufacturing complexity and cost. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130AHM3_B/I | Halogen-free variant with identical electrical specs and AEC-Q101 qualification; same SMB package and pinout. | Required where halogen-free compliance (IEC 61249-2-21) is mandated for green manufacturing or export regulations. | Select SMBJ130AHM3_B/I when RoHS + halogen-free material declaration is contractually required; no design or layout changes needed. |
| SMCJ130AHE3_A/I | Same VWM, VBR, VC, and PPPM, but in larger SMC (DO-214AB) package with higher IPPM (4.7 A) and lower RθJA (60 °C/W). | Better suited for high-repetition-rate surges or elevated ambient temperatures (>85 °C) due to superior thermal dissipation. | Choose SMCJ130AHE3_A/I when board space allows and thermal performance must exceed SMBJ130AHE3_B/I's 100 °C/W limit. |
Compared with SMBJ130AHE3_B/I, the HM3 variant offers identical protection performance with halogen-free materials, while the SMCJ130AHE3_A/I provides higher surge current headroom and better thermal management at the cost of larger footprint - enabling trade-offs between compliance, reliability, and PCB area.

FAQ
What is the clamping voltage of SMBJ130AHE3_B/I at its rated peak pulse current?
The SMBJ130AHE3_B/I has a maximum clamping voltage (VC) of 209 V at its rated peak pulse current (IPPM) of 2.9 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream components such as 200 V MOSFETs or isolated gate drivers in industrial and automotive designs using SMBJ130AHE3_B/I.
Is SMBJ130AHE3_B/I qualified for automotive applications?
Yes, SMBJ130AHE3_B/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88392. This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock - making SMBJ130AHE3_B/I suitable for under-hood and chassis-mounted automotive electronics such as body control modules and ADAS power supplies.
What is the standoff voltage (VWM) and why does it matter for SMBJ130AHE3_B/I?
The standoff voltage (VWM) of SMBJ130AHE3_B/I is 130 V - the maximum DC or continuous reverse voltage the device can block without entering breakdown. This parameter defines the operating margin below the clamping threshold and ensures minimal leakage (<1.0 µA) during normal operation, which is essential for low-power systems like LIN bus nodes or always-on microcontroller rails protected by SMBJ130AHE3_B/I.
How does the SMB (DO-214AA) package of SMBJ130AHE3_B/I affect PCB layout and thermal performance?
The SMB (DO-214AA) package of SMBJ130AHE3_B/I measures 5.59 mm × 4.06 mm with a 2.20 mm height and requires minimum 5.0 mm × 5.0 mm copper pads per terminal for rated thermal performance. Its RθJA of 100 °C/W means board layout must prioritize thermal relief and copper area - unlike larger SMC packages - to maintain junction temperature below 150 °C during repeated surges when using SMBJ130AHE3_B/I.
Can SMBJ130AHE3_B/I be used in bidirectional protection circuits?
No, SMBJ130AHE3_B/I is a unidirectional TVS diode, as indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay specifies the "CA" suffix (e.g., SMBJ130CA). Using SMBJ130AHE3_B/I in bidirectional configurations would result in forward conduction during negative transients, potentially damaging the device or failing to protect - always verify polarity and suffix before deploying SMBJ130AHE3_B/I.
