Product details
Overview
SMBJ130AHM3_A/H 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 per 10/1000 µs waveform - deployed in industrial motor drives, automotive body control modules, and telecom power supplies.
For engineers reviewing the SMBJ130AHM3_A/H datasheet, SMBJ130AHM3_A/H pinout, SMBJ130AHM3_A/H application, or SMBJ130AHM3_A/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), halogen-free RoHS compliance (HM3 suffix), and real-world clamping behavior under surge conditions - critical for ESD and lightning-induced transient design validation.
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 enables use on 110–120 V nominal DC bus lines, while the 209 V clamping voltage ensures downstream ICs (e.g., gate drivers, microcontrollers) remain within absolute maximum ratings during 600 W transients.
The SMBJ130AHM3_A/H is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and supports automated SMT placement. Its HM3 suffix confirms halogen-free, RoHS-compliant construction with matte tin-plated leads qualified to JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - Maximum continuous reverse voltage before leakage exceeds 1 µA; sets upper limit for protected circuit's normal operating voltage. |
| 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 IPPM = 2.9 A (10/1000 µs) - Actual voltage seen by protected load during worst-case surge; defines safe margin for downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 µs surge; validates suitability for IEC 61000-4-5 Level 3/4 tests. |
| RθJA (Junction-to-Ambient) | 100 °C/W - Thermal resistance on standard 0.2" × 0.2" copper pads; determines derating needed above 25 °C ambient for continuous reliability. |
| TJmax | +150 °C - Maximum allowable junction temperature; enables operation in under-hood automotive or enclosed industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTOL, TC, AC/DC HAST, and ESD; designated by HM3 suffix. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated for J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal (cathode-banded end is opposite) | Connected to system ground or low-side return path; defines current direction during clamping. |
| Cathode | Avalanche breakdown terminal (marked with band) | Connected to protected line (e.g., 130 V rail); conducts surge current to ground when VWM exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Validates robustness against high-energy surges per IEC 61000-4-5, enabling single-device protection without external series impedance. |

| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and JEDEC J-STD-20; eliminates brominated flame retardants for safer end-of-life processing. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns response), improving protection margin for sensitive gate drivers and ADCs. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profile (peak 260 °C), eliminating bake requirements and simplifying SMT line integration. |

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/H | RoHS-compliant but not halogen-free; uses standard SnPb-free plating without JESD 201 Class 2 whisker qualification. | Approved for commercial/industrial use only; excluded from automotive programs requiring halogen-free materials. | Select when cost sensitivity outweighs halogen-free requirement and AEC-Q101 is not mandated. |
| SMAJ130A-M3 | Lower 400 W PPPM, SMA (DO-214AC) package (smaller footprint, higher RθJA = 140 °C/W), same VWM/VC. | Limited to lower-energy surges (IEC 61000-4-2/4-4); unsuitable for IEC 61000-4-5 Level 4 or automotive load-dump. | Choose for space-constrained consumer electronics where 600 W headroom is unnecessary and thermal budget allows higher RθJA. |
Compared with SMBJ130AHM3_A/H, the SMBJ130AHE3_A/H offers identical electrical performance but lacks halogen-free certification and AEC-Q101 validation, while the SMAJ130A-M3 sacrifices 33 % peak power handling and thermal performance for reduced board area - making SMBJ130AHM3_A/H the optimal choice for automotive-grade, high-energy transient protection.

FAQ
What is the clamping voltage of SMBJ130AHM3_A/H at its rated peak pulse current?
The SMBJ130AHM3_A/H has a maximum clamping voltage (VC) of 209 V at a peak pulse current (IPPM) of 2.9 A, tested with a 10/1000 µs waveform. This value is measured under standardized conditions per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings. The SMBJ130AHM3_A/H maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMBJ130AHM3_A/H qualified for automotive applications?
Yes, SMBJ130AHM3_A/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's official datasheet (Document Number: 88392, Revision: 09-Jan-2024). This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress testing (uHAST), validating its suitability for under-hood and chassis-mounted automotive systems such as body control modules and ADAS power domains.
What does the "HM3" suffix indicate for SMBJ130AHM3_A/H?
The "HM3" suffix in SMBJ130AHM3_A/H denotes halogen-free, RoHS-compliant construction with matte tin-plated leads qualified to JESD 201 Class 2 for whisker resistance. It also signifies compliance with JEDEC J-STD-020 moisture sensitivity level (MSL) 1, allowing unlimited floor life and standard reflow profiles up to 260 °C peak. Unlike the "HE3" variant, HM3 adds halogen-free certification required by many Tier 1 automotive OEMs and green electronics initiatives.
How does SMBJ130AHM3_A/H differ from bidirectional TVS diodes like SMBJ130CA?
SMBJ130AHM3_A/H is unidirectional and functions only during positive overvoltage events (anode grounded, cathode on protected line), whereas SMBJ130CA is bidirectional and clamps both polarities. The unidirectional configuration provides lower leakage current (<1 µA at 130 V) and avoids forward conduction during negative transients - making SMBJ130AHM3_A/H preferable for DC power rail protection where polarity is fixed and leakage must be minimized. Bidirectional variants exhibit higher ID at VWM due to dual-junction structure.
What is the thermal resistance of SMBJ130AHM3_A/H, and how does it affect layout?
SMBJ130AHM3_A/H 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 minimum recommended pad layout per Vishay's package drawing; reducing pad size or omitting thermal vias increases RθJA, potentially causing junction temperatures to exceed 150 °C during repetitive surges. For high-duty-cycle applications, designers should verify thermal margins using the device's 5.0 W steady-state power dissipation rating and ambient temperature constraints.
