Product details
Overview
SMCJ130AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount 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 range (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 from –55 °C to +150 °C junction temperature.
For engineers reviewing the SMCJ130AHM3/H datasheet, SMCJ130AHM3/H pinout, SMCJ130AHM3/H application, or SMCJ130AHM3/H equivalent, key selection criteria include clamping performance under automotive-grade surge conditions, halogen-free RoHS compliance (HM3 suffix), AEC-Q101 qualification, and compatibility with automated SMT assembly on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ130AHM3/H uses a glass-passivated silicon junction optimized for fast response (<1 ns) to transient overvoltages and low incremental surge resistance to minimize clamping overshoot. Its unidirectional polarity features a cathode band marking and supports DC-biased protection paths in power rails and signal lines.
Thermally, it exhibits RθJA = 75 °C/W (typ.) and RθJL = 15 °C/W (typ.), enabling reliable operation up to 150 °C junction temperature when mounted per recommended pad layout. The device meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines upper limit of protected circuit's normal operating range. |
| VBR min/max | 144 V / 159 V at IT = 1 mA - Confirmed breakdown threshold window ensures predictable turn-on during transients without premature conduction. |
| VC @ IPPM | 209 V at 7.2 A (10/1000 μs) - Clamping voltage directly limits peak stress on downstream ICs or MOSFETs during standardized surge events. |
| PPPM | 1500 W - Peak pulse power handling capacity determines survivability against IEC 61000-4-5 Level 4 surges (e.g., 4 kV line-to-earth). |
| ID @ VWM | 1.0 μA - Ultra-low leakage preserves efficiency in high-impedance bias networks and avoids false triggering in precision analog circuits. |
| TJ max. | +150 °C - Enables use in under-hood automotive environments and industrial power supplies where ambient temperatures exceed 105 °C. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 0.305" × 0.220" footprint, compatible with industry-standard pick-and-place and reflow profiles. |
Pinout & Package
SMCJ130AHM3/H is housed in an SMC (DO-214AB) package with two terminals: anode and cathode. The cathode is marked by a band on the body. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward conduction mode; connected to system ground or low-side reference in unidirectional TVS configuration. | Provides return path during clamping; must be routed with low-inductance trace to maintain effective suppression of fast transients. |
| Cathode | Current exit point during clamping; connected to protected line (e.g., 130 V rail or signal input). | Band-marked terminal defines polarity; incorrect orientation prevents clamping and risks catastrophic failure under overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces requiring zero-defect reliability under thermal cycling and vibration stress. |
| Halogen-free & RoHS-compliant (HM3) | Meets global environmental regulations and enables use in green electronics manufacturing without compromising solderability or long-term reliability. |
| 1500 W peak pulse power (10/1000 μs) | Supports robust protection against lightning-induced surges and inductive switching spikes in industrial motor drives and telecom power supplies. |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes voltage overshoot across protected components, reducing risk of gate oxide rupture in MOSFETs and latch-up in microcontrollers. |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow assembly without moisture-related popcorn failure, eliminating pre-bake requirements in high-volume SMT lines. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130AHE3/A | Lower PPPM (400 W), SMA package (smaller thermal mass), same VWM/VBR/VC specs. | Suitable only for lower-energy transients (e.g., IEC 61000-4-2 ESD), not IEC 61000-4-5 surge immunity. | Select when board space is constrained and surge threat level is limited to human-body-model events. |
| SMCJ130A-M3/57T | Same electrical specs and SMC package, but commercial-grade (non-AEC-Q101) and halogen-free RoHS only (no automotive qualification). | Lacks AEC-Q101 validation; not approved for safety-critical automotive subsystems like braking or steering ECUs. | Choose for cost-sensitive industrial controls where automotive qualification is unnecessary and supply chain prioritizes standard commercial variants. |
Compared with SMCJ130AHM3/H, SMAJ130AHE3/A offers smaller footprint but insufficient surge rating for harsh environments, while SMCJ130A-M3/57T matches form/fit/function but omits AEC-Q101 validation-making SMCJ130AHM3/H the sole choice for automotive-grade 1500 W clamping with halogen-free compliance.

FAQ
What is the clamping voltage of SMCJ130AHM3/H at its rated peak pulse current?
The SMCJ130AHM3/H has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM) of 7.2 A under the standard 10/1000 μs waveform. This value is measured at TJ = 25 °C with devices mounted on 8.0 mm × 8.0 mm copper pads per the Vishay datasheet (Document Number: 88394, Rev. 09-Jan-2024). The clamping voltage defines the upper voltage limit imposed on protected circuitry during surge events, making it critical for ensuring downstream component survival.
Is SMCJ130AHM3/H qualified for automotive applications?
Yes, SMCJ130AHM3/H is AEC-Q101 qualified, as confirmed by the HM3 suffix and documentation in Vishay's official datasheet (88394). This qualification validates its reliability under automotive-specific stress tests-including temperature cycling, humidity bias HAST, and mechanical shock-enabling use in engine control units, ADAS sensors, and body electronics. The "HM3" designation explicitly denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction, distinguishing it from commercial-grade variants like SMCJ130A-M3/57T.
What does the "HM3" suffix indicate in SMCJ130AHM3/H?
The "HM3" suffix in SMCJ130AHM3/H specifies three verified attributes: halogen-free material composition, full RoHS compliance, and AEC-Q101 qualification. Per Vishay's ordering information (page 3, Document 88394), HM3 parts meet JESD 201 Class 2 whisker resistance and are rated for MSL Level 1 handling with 260 °C peak reflow. This suffix replaces older "HE3" (RoHS + AEC-Q101) and "M3" (halogen-free RoHS only) codes, confirming SMCJ130AHM3/H meets the strictest environmental and automotive reliability standards simultaneously.
How does the thermal resistance of SMCJ130AHM3/H affect PCB layout?
SMCJ130AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended pad layout, and 15 °C/W junction-to-lead (RθJL). To maintain safe operation below 150 °C junction temperature, PCB layout must use 8.0 mm × 8.0 mm copper pads per terminal as specified in the datasheet. Reducing pad size increases RθJA, risking thermal runaway during repetitive surges; adding internal copper planes or thermal vias improves heat dissipation but requires validation against the published derating curves (Fig. 2, Document 88394).
Can SMCJ130AHM3/H be used in bidirectional protection circuits?
No, SMCJ130AHM3/H is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix and cathode band marking. Bidirectional operation requires the "CA" variant (e.g., SMCJ130CA), which lacks polarity marking and conducts symmetrically in both directions. Using SMCJ130AHM3/H in a bidirectional configuration would result in forward conduction during negative transients, causing excessive current flow, overheating, and potential failure. Always match the device suffix to the circuit's polarity requirements.
