Product details
Overview
1.5SMC130AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, designed for high-energy surge protection. It features a 130 V breakdown voltage (VBR min/max = 124 V / 137 V), 111 V stand-off voltage (VWM), 179 V clamping voltage (VC) at 8.4 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the 1.5SMC130AHM3/I datasheet, 1.5SMC130AHM3/I pinout, 1.5SMC130AHM3/I application, or 1.5SMC130AHM3/I equivalent, this page delivers verified electrical parameters, thermal derating behavior, AEC-Q101 qualification status, halogen-free RoHS compliance, and real-world clamping performance under repetitive transients - critical for ESD and lightning surge design validation.
Technical Context
The 1.5SMC130AHM3/I operates as a unidirectional avalanche diode with glass-passivated junction, enabling fast response (<1 ps) to voltage transients and low incremental surge resistance. Its 1500 W peak pulse power rating is defined per IEC 61000-4-5 with 10/1000 μs waveform and 0.01% duty cycle, and it supports operation across -65 °C to +150 °C junction temperature range.
Thermal performance is characterized by RθJA = 75 °C/W (typ.) on standard 8.0 mm × 8.0 mm copper pads and RθJL = 15 °C/W (typ.), supporting reliable power dissipation up to 6.5 W at 50 °C ambient. The device meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-E3/52 | Lower peak power (600 W), SMB package (smaller footprint), same VWM/VBR range | Not rated for AEC-Q101; limited to commercial-grade consumer/industrial use | Select when board space is constrained and surge energy is ≤600 W (e.g., low-power IoT nodes) |
| 1.5KE130A | Through-hole DO-201 package, identical electrical specs but higher RθJA (100 °C/W), no AEC-Q101 option | Requires wave soldering; unsuitable for fully SMT production or automotive vibration environments | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ130A-E3/52 and 1.5KE130A, the 1.5SMC130AHM3/I delivers higher surge robustness (1500 W vs. 600 W or 1500 W with inferior thermal performance), AEC-Q101 qualification, and halogen-free compliance - making it the preferred choice for production automotive and high-reliability industrial applications requiring SMT assembly.

FAQ
What is the clamping voltage of the 1.5SMC130AHM3/I at its rated peak pulse current?
The 1.5SMC130AHM3/I has a maximum clamping voltage (VC) of 179 V at its specified peak pulse current (IPPM) of 8.4 A, measured under the standard 10/1000 μs double-exponential surge waveform. This value is guaranteed per the Vishay datasheet revision dated 09-Mar-2026 and defines the upper voltage limit imposed on protected circuitry during surge events. The 1.5SMC130AHM3/I maintains this clamping performance across its full operating temperature range.
Is the 1.5SMC130AHM3/I qualified for automotive applications?
Yes, the 1.5SMC130AHM3/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's 1.5SMC Series datasheet (Document Number: 88303). This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD, validating its suitability for under-hood and body-control module applications. The 1.5SMC130AHM3/I is explicitly designated for automotive use in the ordering information table.
What does the "HM3" suffix indicate in 1.5SMC130AHM3/I?
The "HM3" suffix in 1.5SMC130AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering guide, "HM3" combines environmental compliance (halogen-free molding compound) and automotive reliability certification - distinct from "M3" (halogen-free, commercial grade) and "HE3" (RoHS-compliant, AEC-Q101). The trailing "/I" specifies packaging in 13-inch tape-and-reel format (3500 units per reel).
How does the thermal resistance of the 1.5SMC130AHM3/I affect PCB layout?
The 1.5SMC130AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal, as defined in the datasheet. To achieve this rating, PCB layout must allocate minimum pad area per lead and avoid excessive copper isolation. Reducing pad size increases RθJA, risking thermal runaway during repetitive surges - so layout adherence to Vishay's recommended mounting pad dimensions is essential for reliable 1.5SMC130AHM3/I operation.
Can the 1.5SMC130AHM3/I be used in bidirectional configurations?
No, the 1.5SMC130AHM3/I is a unidirectional TVS diode, indicated by the "A" suffix and absence of "CA" in its part number. Bidirectional variants (e.g., 1.5SMC130CA) exist in the same family but feature symmetrical breakdown in both polarities. Using the 1.5SMC130AHM3/I in reverse-biased AC signal paths would result in forward conduction and failure; correct polarity orientation - cathode toward the protected line - is mandatory for proper 1.5SMC130AHM3/I function.
