Product details
Overview
SMCJ130AHE3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 130 V standoff voltage (VWM), 144–159 V breakdown range (VBR at 1 mA), 209 V maximum clamping voltage (VC) at 7.2 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMCJ130AHE3/9AT datasheet, SMCJ130AHE3/9AT pinout, SMCJ130AHE3/9AT application, or SMCJ130AHE3/9AT equivalent, this device is selected for automotive-grade ESD/surge protection where AEC-Q101 qualification, low incremental surge resistance, and fast response time (<1 ns) are critical - especially in 12 V/24 V vehicle subsystems, industrial sensor interfaces, and telecom line drivers requiring UL 497B recognition.
Technical Context
The SMCJ130AHE3/9AT operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its VBR threshold to clamp transients while maintaining low leakage (<1 µA at 130 V). Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
Thermally, it exhibits RθJA = 75 °C/W (junction-to-ambient, on recommended 8 mm × 8 mm copper pads) and RθJL = 15 °C/W (junction-to-lead), enabling effective heat dissipation during high-energy pulses. It meets MSL Level 1 per J-STD-020 and supports peak surge currents up to 200 A (8.3 ms half-sine, unidirectional).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin for 12 V/24 V systems. |
| VBR (min/max) | 144 V / 159 V at 1 mA - Confirmed breakdown range ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 209 V at 7.2 A - Clamping voltage limits downstream IC stress during 10/1000 µs surges; enables design margin vs. 200 V-rated components. |
| PPPM | 1500 W - Peak pulse power handling capability for IEC 61000-4-5 Level 4 (4 kV) surge compliance in industrial and automotive applications. |
| IFSM | 200 A - Non-repetitive forward surge rating supports inrush and load-dump transient immunity in automotive power distribution. |
| TJ max | +150 °C - Junction temperature limit compatible with under-hood automotive environments and high-ambient industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive electronics per stress test requirements including HTOL, TC, HAST, and UHAST. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, matte tin-plated leads, RoHS-compliant and halogen-free (HE3 suffix), polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side connection | Connected to ground or lower-potential node in unidirectional TVS configuration; enables clamping to reference plane. |
| Cathode | Reverse-biased terminal / protected line connection | Connected to the line being protected (e.g., CAN_H, LIN, 24 V supply); conducts avalanche current when VIN > VBR. |
Key Features
| Feature | Design Value |
|---|---|

|---|---|
|
Use Scenario: Protecting 24 V supply inputs in body control modules against load dump (ISO 7637-2 Pulse 5a) and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between battery rail and DC-DC input, responding within <1 ns to suppress spikes above 130 V. Use Value: Limits voltage seen by downstream regulators to ≤209 V, preventing latch-up or permanent damage in PMICs rated for 200 V absolute maximum. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop) of pressure sensors in factory automation PLCs from EFT and surge coupling. IC Role / Device Role / Timing Role: Low-capacitance (typ. <100 pF) TVS connected between signal and ground, absorbing sub-microsecond transients without distorting slow analog signals. Use Value: Maintains signal integrity below 0.1% gain error while surviving 10 kV ESD (IEC 61000-4-2) and 2 kV surge (IEC 61000-4-5). |
| Telecom Line Driver Protection | On-Board Charger (OBC) Control Signal Isolation |
|
Use Scenario: Safeguarding RS-485 transceivers in base station backhaul equipment exposed to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional pair (used in back-to-back configuration) clamping differential and common-mode transients on A/B lines. Use Value: Enables compliance with GR-1089-CORE Zone 3 requirements using minimal board space due to SMC footprint and single-device solution. |
Use Scenario: Protecting isolated gate driver enable signals in EV on-board chargers from high dv/dt coupling across reinforced insulation barriers. IC Role / Device Role / Timing Role: Fast-response TVS placed at secondary-side controller input to shunt coupled transients before they disrupt PWM timing or cause false shutdown. Use Value: Prevents unintended OBC shutdown during AC grid switching events, improving system uptime and reducing fault recovery latency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/57T | Same VWM/VC, but 400 W PPPM; SMA package (smaller, lower thermal mass) | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for automotive load dump | Select when board space is constrained and surge energy is ≤400 W - not a drop-in replacement for SMCJ130AHE3/9AT. |
| SMCJ130CAHE3/9AT | Bidirectional variant; identical VWM, VBR, VC, and PPPM, but symmetric clamping in both polarities | Required for AC-coupled or floating signal lines (e.g., Ethernet PHY, audio jacks); adds no extra cost or footprint | Choose for bidirectional protection needs - same mechanical fit and thermal performance, but different polarity behavior. |
Compared with SMAJ130A-E3/57T, the SMCJ130AHE3/9AT delivers 3.75× higher surge power handling and superior thermal robustness for automotive and industrial use; versus SMCJ130CAHE3/9AT, it offers optimized unidirectional clamping for grounded DC rails, reducing leakage and improving noise immunity in single-supply systems.

FAQ
What is the clamping voltage of the SMCJ130AHE3/9AT at its rated peak pulse current?
The SMCJ130AHE3/9AT has a maximum clamping voltage (VC) of 209 V at its specified peak pulse current (IPPM) of 7.2 A, measured under the standard 10/1000 µs waveform. This value is guaranteed across temperature and unit variation per Vishay Document 88394, ensuring consistent overvoltage limiting for protected circuits downstream of the SMCJ130AHE3/9AT.
Is the SMCJ130AHE3/9AT suitable for automotive applications?
Yes, the SMCJ130AHE3/9AT is AEC-Q101 qualified and explicitly designated for automotive use via its HE3 suffix. It meets stress test requirements including high-temperature operating life, temperature cycling, and humidity testing - making it appropriate for engine control units, body electronics, and ADAS modules where the SMCJ130AHE3/9AT provides certified surge immunity.
What does the "HE3" suffix indicate in SMCJ130AHE3/9AT?
The "HE3" suffix in SMCJ130AHE3/9AT denotes RoHS-compliant construction with AEC-Q101 qualification, distinguishing it from commercial-grade variants (E3) and halogen-free AEC-Q101 versions (HM3). This marking confirms that the SMCJ130AHE3/9AT has undergone full automotive reliability validation and is intended for use in mission-critical vehicular systems.
How does the SMCJ130AHE3/9AT differ from bidirectional TVS diodes like SMCJ130CAHE3/9AT?
The SMCJ130AHE3/9AT is unidirectional and conducts only during reverse overvoltage events, offering lower leakage (<1 µA at 130 V) and optimized clamping for grounded DC rails. In contrast, SMCJ130CAHE3/9AT clamps symmetrically in both directions - essential for AC or floating signals but with higher leakage. The SMCJ130AHE3/9AT is not interchangeable with the CA version without circuit review.
What is the thermal resistance of the SMCJ130AHE3/9AT, and how does it affect layout?
The SMCJ130AHE3/9AT 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. To maintain safe operation during repeated surges, PCB layout must implement these minimum pad dimensions - undersized copper reduces thermal margin and risks premature failure of the SMCJ130AHE3/9AT under sustained transient stress.
