Product details
Overview
SMBJ130AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 130 V stand-off voltage (VWM), 144–159 V breakdown voltage (VBR) at 1 mA test current, 209 A peak pulse current (IPPM) with 10/1000 µs waveform, and clamps to ≤209 V at rated surge current - deployed on power rails and signal lines of industrial motor drives and telecom interface circuits.
For engineers reviewing the SMBJ130AHM3_A/I datasheet, SMBJ130AHM3_A/I pinout, SMBJ130AHM3_A/I application, or SMBJ130AHM3_A/I equivalent, this page delivers verified electrical parameters, thermal behavior under surge conditions, AEC-Q101 qualification status, halogen-free RoHS compliance, and real-world protection use cases for high-reliability embedded systems.
Technical Context
This TVS diode operates as a clamping device in unidirectional configuration, with cathode-banded polarity marking. Its silicon junction is glass passivated for stable leakage performance and robust surge handling. The device responds in <1 ps to transient overvoltages and maintains low incremental surge resistance during 600 W peak pulse events.
Thermal design relies on its RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), enabling effective heat dissipation when mounted on 0.2" × 0.2" copper pads per terminal. It meets MSL Level 1 per J-STD-020 and supports reflow up to 260 °C peak temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC rail margin for protected circuitry. |
| VBR (Breakdown Voltage) | 144–159 V at IT = 1 mA - precise voltage threshold where avalanche conduction initiates; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | ≤209 V at IPPM = 209 A (10/1000 µs) - maximum voltage seen by downstream components during worst-case surge; determines protection margin. |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capability under standardized 10/1000 µs waveform; validates suitability for IEC 61000-4-5 Level 4 surges. |
| ID (Reverse Leakage) | ≤1.0 µA at VWM - negligible standby current; avoids loading of high-impedance sensor or reference circuits. |
| TJ max. | +150 °C - maximum junction temperature rating; supports operation in under-hood automotive and industrial ambient environments. |
| AEC-Q101 Qualified | Yes - qualified for automotive-grade reliability per stress test requirements including HTOL, TCT, and ESD; base code HM3 denotes halogen-free + AEC-Q101. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band marking on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to ground or lower-potential node in unidirectional TVS configuration; enables clamping to GND during positive transients. |
| Cathode | Current exit point during forward conduction; marked with band | Connected to protected line (e.g., 130 V rail); defines directionality and ensures correct orientation for transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 surge immunity testing up to Level 4 (4 kV line-to-line, 2 kV line-to-ground) without degradation. |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage across temperature (-55 °C to +150 °C), critical for long-term field reliability. |
| Halogen-free, RoHS-compliant (HM3 suffix) | Meets environmental compliance mandates for industrial and automotive OEMs; eliminates brominated flame retardants in molding compound. |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow assembly without moisture-related popcorn failure or delamination risk. |
| AEC-Q101 qualified | Validated for automotive applications requiring extended lifetime, thermal cycling endurance, and robust ESD immunity (HBM ≥ 8 kV). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130AHE3_A/I | Same VWM/VBR/VC ratings and SMB package, but RoHS-compliant without halogen-free certification (E3 vs HM3). | Lacks halogen-free compliance; acceptable for commercial-grade industrial designs but not automotive or green-certified programs. | Select when halogen-free requirement is absent and cost optimization is prioritized over material sustainability reporting. |
| SMAJ130A-M3 | Lower PPPM (400 W), smaller SMA (DO-214AC) package, same VWM and AEC-Q101 qualification (M3 suffix). | Reduced surge margin; suitable only for lower-energy transients (<2 kV IEC 61000-4-5) and space-constrained PCB layouts. | Choose when board area is critical and surge threat level is limited to Level 2 or 3; verify thermal derating with RθJA = 140 °C/W. |
Compared with SMBJ130AHM3_A/I, SMBJ130AHE3_A/I offers identical electrical protection but omits halogen-free assurance, while SMAJ130A-M3 trades 33 % lower peak power and higher thermal resistance for footprint reduction - making the original optimal for high-energy, automotive-grade, and environmentally regulated deployments.

FAQ
What is the clamping voltage of SMBJ130AHM3_A/I at its rated peak pulse current?
The SMBJ130AHM3_A/I has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM) of 209 A using the standard 10/1000 µs waveform. This value is measured under defined test conditions per JEDEC standards and ensures downstream circuitry remains within safe operating limits during surge events. The SMBJ130AHM3_A/I achieves this clamping performance while maintaining low incremental surge resistance and fast response time.
Is SMBJ130AHM3_A/I qualified for automotive applications?
Yes, SMBJ130AHM3_A/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's official datasheet (Document Number: 88392). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD robustness - validating its suitability for under-hood and chassis-mounted automotive electronics. The SMBJ130AHM3_A/I meets these requirements while retaining halogen-free and RoHS-compliant construction.
How does the HM3 suffix differ from E3 or HE3 in the SMBJ130A family?
The HM3 suffix on SMBJ130AHM3_A/I indicates halogen-free, RoHS-compliant, and AEC-Q101-qualified construction, whereas E3 denotes RoHS-compliant only (no halogen-free or automotive qualification), and HE3 adds AEC-Q101 qualification but not halogen-free status. These distinctions directly impact material compliance reporting, environmental certifications, and automotive program acceptance - all three variants share identical electrical specs but differ in regulatory scope and manufacturing traceability.
What is the maximum reverse leakage current for SMBJ130AHM3_A/I at its stand-off voltage?
The SMBJ130AHM3_A/I exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 130 V stand-off voltage (VWM), measured at TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance circuits such as sensor bias networks or precision reference paths. The SMBJ130AHM3_A/I maintains this specification across its full operating temperature range (-55 °C to +150 °C), supported by its glass passivated junction technology.
Can SMBJ130AHM3_A/I be used in bidirectional configurations?
No, SMBJ130AHM3_A/I is a unidirectional TVS diode, identified by its cathode band marking and specified electrical characteristics for single-polarity clamping. Bidirectional operation requires a part with "CA" suffix (e.g., SMBJ130CA), which provides symmetrical breakdown in both directions. Using SMBJ130AHM3_A/I in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit - always match suffix and polarity to system topology.
