Product details
Overview
SMCJ130CAHE3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 130 V standoff voltage (VWM), 1500 W peak pulse power (10/1000 μs), and clamping voltage of 209 V at 7.2 A peak pulse current. It protects sensitive ICs, MOSFETs, and sensor signal lines in automotive, industrial, and telecom systems against inductive switching transients and lightning-induced surges.
For engineers reviewing the SMCJ130CAHE3/9AT datasheet, SMCJ130CAHE3/9AT pinout, SMCJ130CAHE3/9AT application, or SMCJ130CAHE3/9AT equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge rating, low thermal resistance (RθJL = 15 °C/W), and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly.
Technical Context
This device operates as a voltage-clamped shunt protector: during overvoltage events exceeding its 130 V standoff threshold, it avalanches to clamp the line at ≤209 V while diverting up to 7.2 A (10/1000 μs). Its glass-passivated junction ensures stable breakdown and fast response (<1 ns), while bidirectional symmetry enables protection on AC-coupled or floating signal paths without polarity concerns.
Thermally, it leverages the SMC package's low RθJL = 15 °C/W to sustain repetitive surges when mounted on 8.0 mm × 8.0 mm copper pads, and its MSL Level 1 rating (260 °C peak reflow) supports standard lead-free assembly. The HE3 suffix confirms AEC-Q101 qualification and RoHS compliance for automotive-grade reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CAHE3/52T | Lower PPPM = 600 W; SMB package (smaller footprint, higher RθJA) | Suitable for space-constrained consumer designs with lower surge exposure | Select when board area is critical and surge threat level is ≤IEC 61000-4-5 Level 2 |
| SMCJ130AHE3/9AT | Unidirectional version; same VWM, VC, and PPPM, but requires polarity-aware placement | Used where DC-biased lines need asymmetric protection (e.g., power supply inputs) | Choose only if circuit topology mandates unidirectional clamping and polarity can be guaranteed |
Compared with SMBJ130CAHE3/52T and SMCJ130AHE3/9AT, the SMCJ130CAHE3/9AT delivers superior surge energy handling in a thermally optimized package while maintaining bidirectional flexibility-critical for AC-coupled or floating interfaces where polarity reversal cannot be excluded.

FAQ
What does the "CA" suffix indicate in SMCJ130CAHE3/9AT?
The "CA" suffix in SMCJ130CAHE3/9AT denotes a bidirectional configuration, meaning the device provides symmetrical clamping for both positive and negative voltage transients. Unlike unidirectional variants (e.g., SMCJ130A), it has no polarity marking and functions identically in either direction-ideal for AC-coupled lines, differential signals, or floating grounds where voltage polarity reversal is possible. This is confirmed in Vishay's documentation under "DEVICES FOR BIDIRECTION APPLICATIONS".
Is SMCJ130CAHE3/9AT qualified for automotive use?
Yes, SMCJ130CAHE3/9AT is AEC-Q101 qualified, as indicated by the "HE3" suffix and explicitly stated in the Vishay datasheet revision 09-Jan-2024. This qualification validates its reliability under automotive temperature cycling, humidity, mechanical shock, and lifetime surge stress conditions. It is approved for use in engine control units, body electronics, ADAS sensors, and infotainment systems where sustained operation from −55 °C to +150 °C is required.
What is the clamping voltage of SMCJ130CAHE3/9AT at its rated peak pulse current?
The clamping voltage (VC) of SMCJ130CAHE3/9AT is 209 V at its rated peak pulse current (IPPM) of 7.2 A, measured under the standard 10/1000 μs double-exponential waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table on page 2 of the Vishay document number 88394 and defines the maximum voltage imposed on protected circuitry during a full 1500 W surge event.
How does the SMC (DO-214AB) package of SMCJ130CAHE3/9AT support thermal performance?
The SMC (DO-214AB) package of SMCJ130CAHE3/9AT delivers a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W, enabling efficient heat transfer from the silicon die to the PCB copper pads. When mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, this allows sustained surge duty cycles and prevents thermal runaway during repetitive transients-critical for automotive and industrial applications where ambient temperatures exceed 100 °C.
Can SMCJ130CAHE3/9AT replace SMCJ130AHE3/9AT in a design?
No, SMCJ130CAHE3/9AT cannot directly replace SMCJ130AHE3/9AT without layout review: the former is bidirectional (no polarity marking), while the latter is unidirectional (cathode band marked). Substituting them requires verifying that the circuit does not rely on DC bias polarity-for example, replacing SMCJ130AHE3/9AT on a power rail would require confirming the line is truly floating or AC-coupled. The SMCJ130CAHE3/9AT datasheet explicitly states bidirectional electrical characteristics apply in both directions, unlike the unidirectional variant.
