Product details
Overview
SMBJ130AHM3/H 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 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 - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ130AHM3/H datasheet, SMBJ130AHM3/H pinout, SMBJ130AHM3/H application, or SMBJ130AHM3/H equivalent, this page delivers verified electrical specs, thermal behavior, AEC-Q101 qualification status, halogen-free RoHS compliance, and real-world protection use cases - all aligned to Vishay's 88392 specification revision (Jan 2024).
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, optimized for fast response (<1 ps typical) to ESD and lightning-induced surges. Its glass-passivated junction ensures stable leakage performance (≤1.0 µA at VWM) and low incremental surge resistance, enabling precise overvoltage limiting without latch-up.
Thermally, it exhibits RθJA = 100 °C/W (junction-to-ambient, on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W (junction-to-lead), supporting continuous operation up to TJ = +150 °C. The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum reverse working voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 144 V / 159 V at IT = 1 mA - Ensures predictable turn-on across production lot; guarantees clamping initiates above system nominal voltage. |
| VC @ IPPM | 209 V at 2.9 A (10/1000 µs) - Peak clamped voltage seen by protected circuit; determines minimum voltage tolerance of downstream components. |
| PPPM | 600 W - Surge energy absorption capacity under standardized transient waveform; validates robustness against IEC 61000-4-5 Level 4 events. |
| IFSM | 100 A (8.3 ms half-sine) - Withstands high-energy inrush or fault currents without bond-wire fusing. |
| TJ max. | +150 °C - Enables deployment in under-hood automotive modules and industrial motor drives with elevated ambient temperatures. |
| Package | SMB (DO-214AA) - Low-profile SMT footprint (5.21 mm × 4.06 mm × 2.20 mm); compatible with automated pick-and-place and reflow soldering per J-STD-020 MSL level 1. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional configuration with cathode band marking on one end. Matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-potential rail; completes clamping path during transient events. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., 12 V rail, CAN H, sensor VDD); absorbs positive-going transients when forward-biased relative to anode. |
Key Features

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/H | RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification; same VWM, VBR, and VC specs. | Suitable for commercial-grade industrial equipment where automotive qualification is unnecessary. | Select when halogen-free content or automotive qualification is not required; lower cost alternative with identical electrical performance. |
| SMCJ130A-HM3 | Same VWM/VBR ratings but in larger SMC (DO-214AB) package; higher PPPM = 1500 W; RθJA = 50 °C/W. | Better suited for high-energy surge environments (e.g., outdoor telecom cabinets) requiring >600 W dissipation. | Choose when board space allows larger footprint and system-level surge testing exceeds 600 W requirements. |
Compared with SMBJ130AHM3/H, SMBJ130AHE3/H offers identical clamping performance at lower qualification tier, while SMCJ130A-HM3 trades compact SMB size for higher surge handling - making SMBJ130AHM3/H optimal for space-constrained automotive and industrial designs needing halogen-free AEC-Q101 assurance.

FAQ
What is the maximum clamping voltage of SMBJ130AHM3/H under a 10/1000 µs surge?
The SMBJ130AHM3/H has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current of 2.9 A using the 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 transient events. Designers must ensure downstream components tolerate this clamped level with margin.
Is SMBJ130AHM3/H qualified for automotive applications?
Yes, SMBJ130AHM3/H is AEC-Q101 qualified, as confirmed by the "HM3" suffix and documentation in Vishay's 88392 datasheet (Revision 09-Jan-2024). This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for automotive body electronics, infotainment power rails, and ADAS sensor interfaces.
What does the "HM3" suffix indicate for SMBJ130AHM3/H?
The "HM3" suffix on SMBJ130AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from "HE3" (RoHS-compliant, AEC-Q101) and "E3/M3" (commercial-grade only). The "H" specifically signals halogen-free molding compound meeting JEDEC JS709B, while "M3" confirms compliance with RoHS Directive 2011/65/EU and JESD201 Class 2 whisker resistance.
How does SMBJ130AHM3/H compare to bidirectional TVS diodes like SMBJ130CA?
SMBJ130AHM3/H is unidirectional and intended for DC line protection where polarity is fixed (e.g., 12 V supply rails), offering lower leakage and tighter VBR tolerance than bidirectional variants. In contrast, SMBJ130CA protects AC or floating signal lines but exhibits higher reverse leakage and symmetrical clamping. For SMBJ130AHM3/H, the cathode band identifies polarity; no marking exists on bidirectional types.
What is the thermal resistance of SMBJ130AHM3/H, and how does it affect layout design?
SMBJ130AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per terminal, as specified in Vishay document 88392. This value assumes minimal copper area; increasing pad size or adding thermal vias reduces RθJA, lowering junction temperature during repetitive surges. Layouts must avoid narrow traces between terminals to maintain effective heat spreading.
