Product details
Overview
SMCJ130CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features a 130 V standoff voltage (VWM), 209 V maximum clamping voltage (VC) at 7.2 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the SMCJ130CAHE3_A/I datasheet, SMCJ130CAHE3_A/I pinout, SMCJ130CAHE3_A/I application, or SMCJ130CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low incremental surge resistance, thermal performance under repetitive surge stress, and compatibility with automated SMT assembly on 8 mm × 8 mm copper pads.
Technical Context
The SMCJ130CAHE3_A/I operates as a silicon avalanche diode with symmetrical breakdown behavior in both directions, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown voltage and low leakage (<1.0 µA at VWM), while the low RθJA of 75 °C/W supports reliable operation up to +150 °C junction temperature.
It delivers fast response time (<1.0 ns) and low dynamic impedance during transient events, maintaining clamping within specification across ambient temperatures from –55 °C to +150 °C. The device meets J-STD-020 MSL Level 1 and is qualified to AEC-Q101 for automotive applications, with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 12 V–48 V bus systems with transient headroom. |
| VBR min/max | 144 V / 159 V at IT = 1 mA - Confirmed breakdown threshold range ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 209 V at 7.2 A (10/1000 µs) - Clamping voltage limits downstream component stress; enables robust protection of 150 V-rated devices. |
| PPPM | 1500 W - Peak transient energy handling capacity; supports IEC 61000-4-5 Level 4 surge immunity testing. |
| ID @ VWM | <1.0 µA - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | +150 °C - Enables deployment in under-hood automotive environments and industrial enclosures without derating. |
| Package | SMC (DO-214AB) - Standardized 2-pin surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with JEDEC MS-013. |
Pinout & Package
SMCJ130CAHE3_A/I uses a 2-terminal SMC (DO-214AB) package with no polarity marking for bidirectional operation. Terminals are matte tin-plated leads suitable for reflow soldering per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | Accepts surge current from either direction; connects to protected line or common node in differential or floating topologies. |
| Cathode | Transient current exit (bidirectional) | Completes low-impedance path to ground or return rail; symmetric with Anode due to bidirectional construction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - required for engine control, ADAS, and body electronics. |
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., CAN, RS-485), and ungrounded power rails without polarity constraints. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during fast transients, reducing risk of latch-up or gate oxide damage in protected MOSFETs and ICs. |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow profiles without baking - simplifies manufacturing and reduces process risk. |
| Glass-passivated junction | Ensures long-term stability of breakdown voltage and leakage current across humidity, temperature, and lifetime stress conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130AHE3_A/I | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher VC (219 V at 2.9 A) | Targeted for space-constrained consumer electronics; insufficient for automotive load dump compliance. | Select only when board area is critical and surge energy is limited to <400 W. |
| SMCJ130AHE3_A/I | Unidirectional version; same VWM, VBR, and PPPM but asymmetric clamping (cathode-banded); VF = 3.5 V at 100 A forward conduction | Required where DC bias exists and reverse conduction must be blocked (e.g., DC power input protection). | Choose unidirectional SMCJ130AHE3_A/I only if circuit topology mandates polarity-aware clamping. |

FAQ
What is the clamping voltage of SMCJ130CAHE3_A/I at its rated peak pulse current?
The SMCJ130CAHE3_A/I has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM) of 7.2 A using the standard 10/1000 µs waveform. This value is measured under specified test conditions per JEDEC standards and reflects worst-case voltage seen by downstream components during surge events. The SMCJ130CAHE3_A/I maintains this clamping performance across its full operating temperature range from –55 °C to +150 °C.
Is SMCJ130CAHE3_A/I suitable for automotive applications?
Yes, the SMCJ130CAHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix and ordering code structure. It meets requirements for temperature cycling, high-temperature reverse bias, and surge endurance relevant to engine control units, body electronics, and ADAS modules. The SMCJ130CAHE3_A/I also complies with J-STD-020 MSL Level 1, supporting standard reflow assembly without moisture sensitivity concerns.
How does the bidirectional design of SMCJ130CAHE3_A/I affect its circuit placement?
The bidirectional design of SMCJ130CAHE3_A/I eliminates polarity constraints, allowing placement between any two nodes - such as across a differential signal pair, between a floating power rail and ground, or across transformer windings - without regard to anode/cathode orientation. Unlike unidirectional variants, the SMCJ130CAHE3_A/I has no band marking and delivers identical clamping behavior in both directions, simplifying layout and reducing BOM complexity in AC-coupled or isolated systems.
What is the thermal resistance of SMCJ130CAHE3_A/I, and how does it impact PCB layout?
The SMCJ130CAHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pad per terminal. To maintain safe junction temperature under repetitive surge conditions, PCB layout must allocate sufficient copper area and avoid thermal bottlenecks. The SMCJ130CAHE3_A/I's RθJL of 15 °C/W further supports heat transfer through leads into internal copper planes, especially in multilayer boards with thermal vias.
Can SMCJ130CAHE3_A/I replace SMCJ130AHE3_A/I in an existing design?
No - the SMCJ130CAHE3_A/I is bidirectional, while the SMCJ130AHE3_A/I is unidirectional and includes a cathode band. Substituting them requires verifying that the circuit does not rely on DC blocking in one direction. If the original design uses the unidirectional part to prevent reverse conduction (e.g., on a DC input rail), replacing it with the SMCJ130CAHE3_A/I could allow unintended reverse current flow. Always validate functionality and perform surge testing before interchange. The SMCJ130CAHE3_A/I remains functionally distinct and not a drop-in replacement for SMCJ130AHE3_A/I.
