Product details
Overview
SMCJ130AHM3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 130 V standoff voltage (VWM), 144–159 V breakdown voltage (VBR), and 209 V clamping voltage (VC) at 7.2 A peak pulse current (IPPM). It delivers 1500 W peak pulse power (10/1000 µs waveform) and operates across -55 °C to +150 °C junction temperature range, targeting automotive and industrial power rail protection.
For engineers reviewing the SMCJ130AHM3/I datasheet, SMCJ130AHM3/I pinout, SMCJ130AHM3/I application, or SMCJ130AHM3/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, 7.2 A surge current handling, and thermal resistance of 75 °C/W (junction-to-ambient).
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective clamping of ESD and lightning-induced transients on DC power lines. Its unidirectional configuration provides cathode-anode polarity with band marking, and it meets UL 497B recognition (QVGQ2) for protector classification.
The device is rated for 1500 W peak pulse power under standardized 10/1000 µs waveform conditions, with derating above 25 °C ambient per Figure 2. Thermal performance is characterized by RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation on minimum recommended 8.0 mm × 8.0 mm copper pads per terminal.
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 rail margin. |
| VBR (Breakdown Voltage) | 144–159 V at 1 mA - Voltage at which device enters avalanche conduction; ensures precise turn-on threshold. |
| VC (Clamping Voltage) | 209 V at IPPM = 7.2 A - Maximum voltage seen by protected circuit during full-rated surge; determines downstream IC survivability. |
| PPPM (Peak Pulse Power) | 1500 W (10/1000 µs) - Energy-handling capability for transient suppression; validates robustness against IEC 61000-4-5 Level 4 surges. |

Pinout & Package
SMCJ130AHM3/I is housed in an SMC (DO-214AB) surface-mount package with two terminals: cathode (marked with band) and anode. The package features matte tin-plated leads, complies with J-STD-002 and JESD 22-B102 solderability standards, and meets JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased terminal in normal operation | Connected to protected line (e.g., +12 V rail); conducts during overvoltage to shunt surge current to ground. |
| Anode | Reference/ground return path | Typically tied to system ground or low-impedance return plane; completes clamping path during transient events. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power rating | Enables protection against severe transients per IEC 61000-4-5 (4 kV/2 Ω coupling) without derating in compact layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/57T | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W), non-AEC-Q101. | Suitable for cost-sensitive consumer electronics with lower surge threat levels; not qualified for automotive use. | Select when board space is constrained and surge energy is limited to <400 W; verify thermal margin with RθJA derating. |
| SMCJ130AHE3_A/I | Same electrical specs and SMC package, but RoHS-compliant commercial grade (E3) without halogen-free or AEC-Q101 qualification. | Applicable in industrial automation where AEC-Q101 is not mandated and halogen content is unrestricted. | Choose for non-automotive applications requiring identical clamping performance but without automotive reliability validation. |
Compared with SMCJ130AHM3/I, SMAJ130A-E3/57T offers smaller size but significantly reduced surge capacity and no automotive qualification, while SMCJ130AHE3_A/I matches performance but lacks halogen-free construction and AEC-Q101 validation-making SMCJ130AHM3/I the only option meeting all three criteria: 1500 W rating, AEC-Q101, and halogen-free compliance.

FAQ
What is the clamping voltage of the SMCJ130AHM3/I at its rated peak pulse current?
The SMCJ130AHM3/I has a maximum clamping voltage (VC) of 209 V at its rated peak pulse current (IPPM) of 7.2 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on the protected circuit during full-rated surge events. The SMCJ130AHM3/I maintains this clamping performance across its specified operating temperature range.
Is the SMCJ130AHM3/I suitable for automotive applications?
Yes, the SMCJ130AHM3/I is AEC-Q101 qualified, as confirmed by the HM3 suffix in its part number and documentation in Vishay's SMCJ5.0A–SMCJ188CA datasheet (Rev. 09-Jan-2024). It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-to meet automotive reliability requirements. The SMCJ130AHM3/I is explicitly intended for use in automotive power distribution, body electronics, and ADAS subsystems.
How does the SMCJ130AHM3/I differ from the SMCJ130AHE3_A/I variant?
The SMCJ130AHM3/I and SMCJ130AHE3_A/I share identical electrical specifications (VWM = 130 V, VBR = 144–159 V, VC = 209 V) and SMC package, but differ in qualification and material compliance. The SMCJ130AHM3/I carries the HM3 suffix, indicating halogen-free, RoHS-compliant, and AEC-Q101-qualified construction, whereas SMCJ130AHE3_A/I is RoHS-compliant (E3) but not halogen-free or AEC-Q101 validated. Both are manufactured by Vishay General Semiconductor.
What is the thermal resistance of the SMCJ130AHM3/I, and how does it affect PCB layout?
The SMCJ130AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W, measured on 8.0 mm × 8.0 mm copper pads per terminal. To maintain safe junction temperatures during repetitive surges, PCB layout must provide adequate copper area and thermal vias-especially for applications exceeding 10% duty cycle. The SMCJ130AHM3/I's RθJL enables efficient heat transfer to the PCB, reducing reliance on external heatsinking.
Does the SMCJ130AHM3/I have polarity markings, and how is it oriented on the PCB?
Yes, the SMCJ130AHM3/I is a unidirectional TVS diode with a visible cathode band on the SMC (DO-214AB) package body. During PCB layout, the banded end must be connected to the line being protected (e.g., +12 V rail), and the opposite terminal (anode) must connect to ground or the reference plane. Incorrect orientation renders the device ineffective for reverse-polarity surge suppression. The SMCJ130AHM3/I's polarity is defined in Vishay's mechanical drawings and confirmed in the "Polarity" section of its datasheet.
