Overview
SMBJ130AHM3_B/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 (IPPM), and 600 W peak pulse power capability with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom infrastructure.
For engineers reviewing the SMBJ130AHM3_B/H datasheet, SMBJ130AHM3_B/H pinout, SMBJ130AHM3_B/H application, or SMBJ130AHM3_B/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 critical for surge immunity validation in high-reliability DC power rails and I/O line designs.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its 130 V stand-off rating targets nominal 110–130 V DC systems, with clamping performance validated under repetitive 0.01% duty cycle surges.
The device is rated for -55 °C to +150 °C operating junction temperature, exhibits 0.108 %/°C VBR temperature coefficient, and meets J-STD-020 MSL Level 1 moisture sensitivity - enabling lead-free reflow compatibility up to 260 °C peak without preconditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - maximum continuous reverse voltage before significant leakage; sets operating margin for 110–120 V nominal DC bus protection |
| VBR (Breakdown Voltage) | 144–159 V at 1 mA - defines precise avalanche initiation threshold; ensures reliable turn-on before downstream component damage |
| VC (Clamping Voltage) | 209 V at IPPM = 2.9 A - limits transient voltage seen by protected circuit; enables safe operation of 200 V-rated MOSFETs or controllers |
| PPPM (Peak Pulse Power) | 600 W with 10/1000 µs waveform - sustains high-energy lightning-induced surges per IEC 61000-4-5 Level 3/4 testing |
| ID (Reverse Leakage) | 1.0 µA max at VWM - negligible standby power loss; avoids loading sensitive voltage references or high-impedance sensor nodes |
| TJ max. | +150 °C - supports operation in enclosed industrial enclosures or near heat-generating components without derating |
| Package | SMB (DO-214AA) - 0.220" × 0.155" footprint with 0.086" cathode band; compatible with standard SMT pick-and-place and reflow profiles |

IC Role / Device Role / Timing Role: Parallel-mounted TVS across bus capacitor terminals to shunt inductive kickback energy into ground plane. Use Value: Withstands 2.9 A peak pulse current and dissipates 600 W transient energy, preventing bus overvoltage shutdown and extending capacitor lifetime. |
Use Scenario: 4–20 mA current loop interface in hazardous-area pressure transmitter connected to control room via long cable runs susceptible to induced lightning surges. IC Role / Device Role / Timing Role: Series-connected TVS on loop supply line to limit common-mode transients before precision DAC/ADC front-end. Use Value: 1.0 µA max reverse leakage avoids disturbing loop accuracy; 209 V clamping protects 24-bit sigma-delta ADC inputs referenced to 5 V rail. |
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_B/H | Same electrical specs, but RoHS-compliant commercial grade (non-halogen-free, non-AEC-Q101) | Lacks automotive qualification and halogen-free certification; acceptable for non-automotive industrial use | Select when AEC-Q101 and halogen-free requirements are not mandated; lower cost alternative with identical clamping performance |
| SMBJ130A-M3/52 | Same SMB package and ratings, but supplied in 7" tape/reel (750 pcs) with M3 suffix (halogen-free, RoHS) | No AEC-Q101 qualification; same thermal and surge specs as HM3 version | Choose for high-volume SMT production requiring standard reel packaging and halogen-free compliance without automotive validation |
Compared with SMBJ130AHM3_B/H, the HE3 variant trades AEC-Q101 and halogen-free compliance for cost savings in non-automotive settings, while the M3/52 offers identical environmental specs in a different reel format - making HM3 the only option meeting full automotive-grade and green-material requirements simultaneously.

FAQ
What is the maximum clamping voltage of SMBJ130AHM3_B/H at its rated peak pulse current?
The SMBJ130AHM3_B/H has a maximum clamping voltage (VC) of 209 V at its specified peak pulse current (IPPM) of 2.9 A, measured using the standardized 10/1000 µs double-exponential waveform. This value is guaranteed across the full operating temperature range and ensures protected downstream components see no more than 209 V during surge events. The SMBJ130AHM3_B/H data sheet confirms VC is tested per ANSI/IEEE C62.35 and applies to both single-pulse and repetitive 0.01% duty cycle conditions.
Is SMBJ130AHM3_B/H qualified for automotive applications?
Yes, SMBJ130AHM3_B/H is AEC-Q101 qualified, as indicated by the "HM3" suffix - denoting halogen-free, RoHS-compliant, and automotive-grade reliability validation. It undergoes stress testing including high-temperature reverse bias (HTRB), temperature cycling, and ESD per AEC-Q101 Rev D. This makes SMBJ130AHM3_B/H suitable for engine control modules, body electronics, and ADAS power domains where transient immunity and long-term stability are required.
What does the "_B/H" suffix in SMBJ130AHM3_B/H signify?
The "_B/H" suffix in SMBJ130AHM3_B/H specifies packaging and reel configuration: "B" denotes the revision code (document revision B), and "H" indicates 7-inch diameter plastic tape-and-reel packaging containing 750 units. This matches Vishay's ordering convention shown in the datasheet's "ORDERING INFORMATION" table, where "H" corresponds to the preferred package code for 7" reels - critical for automated assembly line setup and inventory planning.
How does SMBJ130AHM3_B/H differ from bidirectional TVS diodes like SMBJ130CA?
SMBJ130AHM3_B/H is unidirectional and features a cathode band for polarity-sensitive placement, whereas SMBJ130CA is bidirectional with no polarity marking and symmetrical clamping in both directions. The unidirectional SMBJ130AHM3_B/H offers lower leakage (<1.0 µA at VWM) and higher surge current capability in forward conduction mode, making it ideal for DC power rail protection. In contrast, SMBJ130CA suits AC-coupled or floating signal lines where polarity reversal may occur.
What is the thermal resistance from junction to ambient for SMBJ130AHM3_B/H?
The typical thermal resistance from junction to ambient (RθJA) for SMBJ130AHM3_B/H is 100 °C/W, measured on a standard 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad layout per JEDEC standards. This value assumes no additional heatsinking and informs derating calculations - for example, at 50 °C ambient, the device can dissipate up to 5.0 W continuously. RθJA directly impacts safe operating area during repetitive surge events and must be considered alongside PCB copper area and airflow in thermal design.
