Product details
Overview
1.5SMC130AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 130 V breakdown voltage (VBR = 124–137 V at 1 mA), 111 V standoff voltage (VWM), and 1500 W peak pulse power (10/1000 μs). It clamps transients to ≤179 V at 8.4 A peak pulse current and is AEC-Q101 qualified for automotive use.
For engineers reviewing the 1.5SMC130AHM3_A/I datasheet, 1.5SMC130AHM3_A/I pinout, 1.5SMC130AHM3_A/I application, or 1.5SMC130AHM3_A/I equivalent, this device serves as a robust, halogen-free, RoHS-compliant overvoltage protection solution for automotive power rails, sensor interfaces, and industrial control inputs where fast response (<1 ns), low clamping ratio (1.61), and high surge reliability are required.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging a glass-passivated silicon junction for stable avalanche behavior under repetitive transient stress. Its 10/1000 μs waveform rating reflects standardized surge immunity testing per IEC 61000-4-5 and ANSI/IEEE C62.35.
Thermal performance is defined by RθJA = 75 °C/W (typ.) and RθJL = 15 °C/W (typ.), enabling reliable operation up to TJ = 150 °C. The device meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak temperature.

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 | Same VBR range (124–137 V), but lower PPPM = 400 W and SMA package (smaller thermal mass) | Limited to lower-energy transients; unsuitable for automotive load dump or telecom lightning tests | Select only for space-constrained consumer applications with <500 W surge exposure |
| 1.5KE130A | Through-hole DO-201 package, identical electrical specs but no AEC-Q101 qualification or halogen-free status | Not approved for automotive production; requires PCB through-hole layout and wave solder process | Use only in legacy industrial designs where surface-mount assembly is unavailable |
Compared with 1.5SMC130AHM3_A/I, SMAJ130A-E3/57T offers reduced surge robustness and thermal capability, while 1.5KE130A lacks automotive qualification and modern environmental compliance-making 1.5SMC130AHM3_A/I the sole choice for new AEC-Q101-compliant, surface-mount designs requiring full 1500 W immunity.

FAQ
What is the clamping voltage of the 1.5SMC130AHM3_A/I under maximum surge conditions?
The 1.5SMC130AHM3_A/I clamps to a maximum of 179 V when subjected to its rated 8.4 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during worst-case transients. The 1.5SMC130AHM3_A/I maintains this clamping performance across its full operating temperature range.
Is the 1.5SMC130AHM3_A/I suitable for automotive applications?
Yes, the 1.5SMC130AHM3_A/I is AEC-Q101 qualified and explicitly designated for automotive use via its HM3 suffix and "_A" revision code. It meets requirements for temperature cycling, high-temperature reverse bias, and surge endurance relevant to engine control units, body electronics, and ADAS sensors. Its halogen-free, RoHS-compliant construction and MSL Level 1 rating further support reflow-compatible automotive manufacturing.
What does the "HM3_A/I" suffix indicate in 1.5SMC130AHM3_A/I?
The "HM3" denotes halogen-free and RoHS-compliant construction; "_A" specifies AEC-Q101 qualification for the 1.5SMC6.8A–1.5SMC220A voltage range; and "/I" indicates packaging in 13-inch tape-and-reel format (3500 units per reel). This full suffix confirms the 1.5SMC130AHM3_A/I meets automotive environmental, reliability, and logistics requirements simultaneously.
How does the 1.5SMC130AHM3_A/I compare to bidirectional TVS diodes?
The 1.5SMC130AHM3_A/I is unidirectional and intended for DC line protection where polarity is fixed (e.g., +12 V rail to ground). Unlike bidirectional variants (e.g., 1.5SMC130CA), it blocks reverse voltage up to −1.5 V but conducts only positive surges above VBR. This enables tighter clamping on powered lines and avoids leakage issues in asymmetric bias networks-key for automotive power domains where ground-referenced transients dominate.
What is the thermal resistance of the 1.5SMC130AHM3_A/I, and how does it affect layout?
The 1.5SMC130AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads per terminal. To maintain TJ ≤ 150 °C under continuous 6.5 W dissipation, PCB layout must provide adequate copper area and avoid thermal bottlenecks. Reducing pad size or adding thermal vias directly beneath the SMC body significantly lowers RθJA, improving surge survivability in high-duty-cycle applications.
