Product details
Overview
SMBJ130AHE3/52 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 DC power rails and signal lines. It features a 130 V standoff voltage (VWM), 144–159 V breakdown range (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 a 10/1000 µs waveform - deployed in industrial motor drives and automotive body control modules.
For engineers reviewing the SMBJ130AHE3/52 datasheet, SMBJ130AHE3/52 pinout, SMBJ130AHE3/52 application, or SMBJ130AHE3/52 equivalent, this device is evaluated for high-energy surge immunity in 12–48 V systems, reverse polarity protection, and IEC 61000-4-5 compliance-critical interfaces where low leakage (<1.0 µA at VWM) and AEC-Q101 qualification are required.
Technical Context
This unidirectional TVS operates as a clamping device: under normal bias it presents <1.0 µA reverse leakage at 130 V, but triggers into avalanche conduction when transients exceed its 144–159 V breakdown threshold. Its 209 V clamping voltage at 2.9 A ensures downstream ICs (e.g., microcontrollers, gate drivers) remain below absolute maximum ratings during 600 W surge events.
The SMBJ130AHE3/52 uses a glass-passivated silicon junction, exhibits a +0.108 %/°C temperature coefficient of VBR, and is rated for operation from –55 °C to +150 °C. Its 100 °C/W junction-to-ambient thermal resistance assumes mounting on 0.2" × 0.2" copper pads - critical for sustained 5.0 W power dissipation at elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - Maximum continuous reverse operating voltage before significant leakage; defines upper limit of protected circuit's nominal DC rail. |
| VBR (Breakdown Voltage) | 144–159 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above system overvoltage thresholds. |
| VC (Clamping Voltage) | 209 V at 2.9 A (10/1000 µs) - Peak voltage seen by protected load during worst-case surge; determines minimum safe voltage margin for downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustains standardized 10/1000 µs surge without failure; validates suitability for IEC 61000-4-5 Level 4 (4 kV) testing. |
| IPPM (Peak Pulse Current) | 2.9 A - Maximum transient current the device safely shunts; directly linked to PCB trace width and fuse coordination. |
| TJmax | +150 °C - Enables use in under-hood automotive environments and enclosed industrial enclosures without derating penalties. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; supports HE3 suffix designation. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. 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 voltage exceeds VBR. |
| Anode (unbanded end) | Reference / return path | Typically tied to system ground or low-impedance return; completes clamping path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Validates robustness against lightning-induced surges and inductive switching spikes in 24–48 V industrial systems. |
| AEC-Q101 qualified (HE3 suffix) | Confirms automotive-grade reliability for body electronics, ADAS power supplies, and gateway ECUs requiring zero field failures. |
| Low 1.0 µA max reverse leakage at VWM | Minimizes standby power loss in battery-backed systems and avoids false triggering in high-impedance sensor interfaces. |
| 100 °C/W RθJA (on 0.2" × 0.2" Cu) | Enables thermal design predictability for board-level layout - no heatsink needed for intermittent surge duty cycles. |
| Glass-passivated junction | Ensures stable VBR and leakage performance across humidity, temperature, and long-term operational life. |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-E3/52 | Commercial-grade (non-AEC-Q101); identical electrical specs but lacks automotive qualification testing. | Acceptable for industrial or consumer equipment where automotive reliability is not mandated. | Select when cost sensitivity outweighs need for AEC-Q101 documentation and test reports. |
| SMBJ130CAHE3/52 | Bidirectional variant; symmetric VBR (144–159 V) in both polarities; same VC and PPPM. | Required for AC-coupled or floating signal lines (e.g., RS-485, CAN FD) where polarity reversal occurs. | Choose only if bidirectional clamping is explicitly needed - unidirectional SMBJ130AHE3/52 offers lower leakage in DC applications. |
Compared with SMBJ130A-E3/52, the SMBJ130AHE3/52 adds AEC-Q101 validation for automotive use without altering clamping behavior; versus SMBJ130CAHE3/52, it provides superior reverse leakage control in single-polarity DC rails but cannot protect against negative-going transients.

FAQ
What is the clamping voltage of SMBJ130AHE3/52 at its rated peak pulse current?
The SMBJ130AHE3/52 has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current of 2.9 A using the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88392 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ130AHE3/52 maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is SMBJ130AHE3/52 suitable for automotive applications?
Yes, SMBJ130AHE3/52 is AEC-Q101 qualified, as confirmed by its HE3 suffix and inclusion in Vishay's automotive-grade product listing. It undergoes stress testing for temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev D. The SMBJ130AHE3/52 is approved for use in body control modules, lighting systems, and infotainment power supplies where automotive reliability and zero-defect operation are mandatory.
How does the leakage current of SMBJ130AHE3/52 compare to similar TVS diodes at 130 V?
At its 130 V stand-off voltage (VWM), the SMBJ130AHE3/52 guarantees a maximum reverse leakage current of 1.0 µA at 25 °C - significantly lower than many competing 130 V TVS devices that specify up to 5–10 µA. This low leakage minimizes standby power loss in battery-operated systems and prevents false triggering in high-impedance sensor circuits. The SMBJ130AHE3/52 achieves this via precision glass-passivated junction processing.
What is the thermal resistance of SMBJ130AHE3/52, and how does it affect PCB layout?
The SMBJ130AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard JEDEC test conditions and dictates minimum copper area requirements: reducing pad size increases RθJA, risking thermal runaway during repetitive surges. For optimal performance, the SMBJ130AHE3/52 should be placed near ground planes with short, wide traces to maintain thermal integrity.
Can SMBJ130AHE3/52 replace SMBJ130A-E3/52 in existing designs?
Yes, SMBJ130AHE3/52 is a direct drop-in replacement for SMBJ130A-E3/52 in terms of footprint, pinout, and electrical characteristics - differing only in AEC-Q101 qualification and enhanced process controls. No PCB changes are required. The SMBJ130AHE3/52 retains identical VWM, VBR, VC, and PPPM values, making it fully compatible for upgrading commercial designs to automotive-grade reliability without redesign effort.
