Product details
Overview
1.5SMC130AHE3/9AT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 130 V breakdown voltage (VBR = 124–137 V), 111 V maximum standoff voltage (VWM), and clamps transients to ≤179 V at 8.4 A peak pulse current (IPPM) under 10/1000 µs waveform - delivering 1500 W peak pulse power capability. It is AEC-Q101 qualified, RoHS-compliant, and used to protect MOSFETs, ICs, and sensor interfaces in automotive power systems.
For engineers reviewing the 1.5SMC130AHE3/9AT datasheet, 1.5SMC130AHE3/9AT pinout, 1.5SMC130AHE3/9AT application, or 1.5SMC130AHE3/9AT equivalent, this part serves as a high-reliability, low-clamping-voltage TVS for 12–48 V automotive subsystems, industrial DC power rails, and telecom interface protection where surge immunity per IEC 61000-4-5 Level 3/4 is required.
Technical Context
This unidirectional TVS operates by avalanche breakdown above its reverse standoff voltage (111 V), rapidly transitioning to low-impedance conduction to shunt transient energy away from protected circuitry. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance (Rdyn ≈ 12.5 Ω, derived from ΔVC/ΔIPPM), enabling precise clamping control during fast-rising ESD or lightning-induced surges.
Thermally, it sustains 150 °C junction temperature with RθJA = 75 °C/W (on recommended 8.0 mm × 8.0 mm copper pads) and handles 200 A non-repetitive forward surge (8.3 ms half-sine). The SMC (DO-214AB) package supports automated placement and meets MSL Level 1 (260 °C reflow peak), making it suitable for high-volume automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 111 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets upper limit for normal circuit operation. |
| VBR @ IT = 1 mA | 124–137 V - Breakdown voltage range defining reliable avalanche initiation threshold; ±5% tolerance ensures predictable turn-on. |
| VC @ IPPM = 8.4 A | ≤179 V - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on downstream components. |
| PPPM | 1500 W - Peak pulse power handling capacity; validates suitability for IEC 61000-4-5 4 kV/2 Ω surge testing. |
| IFSM | 200 A - Single half-sine surge current rating (8.3 ms); supports protection against load-dump events in 12 V automotive systems. |
| TJmax | +150 °C - Maximum junction temperature; enables operation in under-hood environments without derating below ambient 125 °C. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with IPC-7351B land patterns. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, polarity indicated by cathode band. Complies with UL 94 V-0 flammability rating and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage events. |
| Anode | Reference / return path | Typically tied to system ground or low-impedance return plane; completes current path during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for engine control, ADAS, and body electronics. |
| 1500 W peak pulse power (10/1000 µs) | Enables single-device protection against severe transients such as ISO 7637-2 Pulse 5a (load dump) up to 120 V in 24 V systems. |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes overvoltage overshoot during suppression, reducing risk of gate oxide damage in protected MOSFETs or logic ICs. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profile use (peak 260 °C) without baking - simplifies SMT manufacturing flow. |
| Glass-passivated junction | Ensures long-term parameter stability and low leakage (<1 µA at VWM) across temperature and lifetime, critical for always-on circuits. |
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-E3/52T | Same VWM (111 V) and VC (179 V), but lower PPPM = 600 W and smaller SMB package (DO-214AA); RθJA = 85 °C/W. | Lower power handling limits use to lighter-duty surges (e.g., IEC 61000-4-2 ESD only); not suitable for load-dump or IEC 61000-4-5. | Select when board space is constrained and surge energy is limited to <600 W; verify thermal margin with reduced copper area. |
| 1.5KE130A | Through-hole TO-204AE (DO-41) package; identical electrical specs (VWM = 111 V, VC = 179 V, PPPM = 1500 W), but no AEC-Q101 qualification. | Lacks automotive qualification and MSL Level 1 rating; unsuitable for reflow-soldered automotive modules. | Choose only for legacy through-hole designs or non-automotive industrial applications where qualification is not mandated. |
Compared with SMBJ130A-E3/52T and 1.5KE130A, the 1.5SMC130AHE3/9AT uniquely combines AEC-Q101 qualification, 1500 W surge capability, and SMC surface-mount compatibility - making it the only option among the three qualified for high-reliability automotive power rail protection with automated assembly support.

FAQ
What is the maximum clamping voltage of the 1.5SMC130AHE3/9AT under a 10/1000 µs surge?
The 1.5SMC130AHE3/9AT clamps to a maximum of 179 V when subjected to its rated peak pulse current of 8.4 A under the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the highest voltage that will appear across protected circuitry during a worst-case transient event.
Is the 1.5SMC130AHE3/9AT suitable for automotive applications?
Yes, the 1.5SMC130AHE3/9AT is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix. It meets requirements for temperature cycling, high-temperature reverse bias, and mechanical shock - making it appropriate for engine control modules, ADAS power supplies, and body electronics where reliability under vibration and thermal stress is critical.
What does the "9AT" suffix indicate in 1.5SMC130AHE3/9AT?
The "9AT" suffix denotes packaging: 13-inch diameter plastic tape-and-reel with 3500 units per reel. This format supports high-speed automated pick-and-place assembly and is optimized for volume production lines requiring consistent feeder compatibility and traceable lot control.
How does the 1.5SMC130AHE3/9AT differ from bidirectional TVS diodes like 1.5SMC130CA?
The 1.5SMC130AHE3/9AT is unidirectional and functions only in reverse-bias avalanche mode, with polarity marked by a cathode band. In contrast, 1.5SMC130CA is bidirectional and symmetrical - suppressing transients of either polarity. Use the unidirectional 1.5SMC130AHE3/9AT on DC rails with defined polarity; choose the CA version for AC-coupled or floating signal lines.
What is the thermal resistance junction-to-ambient for the 1.5SMC130AHE3/9AT?
The typical thermal resistance junction-to-ambient (RθJA) for the 1.5SMC130AHE3/9AT is 75 °C/W when mounted on the recommended 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pad per terminal. This value assumes still air conditions and is essential for calculating allowable power dissipation and junction temperature rise in real-world PCB layouts.
