Product details
Overview
SMCJ130CA-E3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 209 V at 7.2 A peak pulse current, with 1500 W peak pulse power rating and 130 V standoff voltage. It protects sensitive ICs, MOSFETs, and sensor signal lines in automotive, industrial, and telecom systems against inductive switching surges and lightning-induced transients.
For engineers reviewing the SMCJ130CA-E3/9AT datasheet, SMCJ130CA-E3/9AT pinout, SMCJ130CA-E3/9AT application, or SMCJ130CA-E3/9AT equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal resistance (RθJA = 75 °C/W), AEC-Q101 qualification status, and RoHS-compliant commercial-grade construction - all critical for surge protection design validation and BOM selection.
Technical Context
The SMCJ130CA-E3/9AT operates as a bidirectional avalanche diode, exhibiting symmetrical breakdown in both polarities with minimum VBR = 144 V and maximum VBR = 159 V at IT = 1 mA. Its clamping voltage VC is 209 V at IPPM = 7.2 A under 10/1000 µs waveform, delivering low incremental surge resistance and fast response time typical of glass-passivated junction TVS devices.
It is rated for TJ = -55 °C to +150 °C, features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets MSL Level 1 per J-STD-020 with peak reflow temperature of 260 °C. The device has no polarity marking due to bidirectional configuration and is housed in UL 94 V-0 compliant molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum reverse standoff voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (min/max) | 144 V / 159 V at IT = 1 mA - Confirmed bidirectional breakdown range; ensures consistent surge initiation across polarity |
| VC @ IPPM | 209 V at 7.2 A (10/1000 µs) - Clamped voltage seen by protected circuit during worst-case transient; limits stress on downstream components |
| PPPM | 1500 W - Peak pulse power handling capacity; determines survivability against standardized lightning/surge waveforms |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; informs derating requirements for sustained power dissipation |
| ID @ VWM | 1.0 µA max - Reverse leakage at standoff voltage; ensures minimal standby power loss and signal integrity in high-impedance nodes |
| TJ Range | -55 °C to +150 °C - Operating junction temperature window; supports under-hood automotive and industrial ambient conditions |
Pinout & Package

Applications
| Automotive Power Distribution | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protection of 12 V/24 V power rails feeding ECUs, body control modules, and lighting drivers against load dump and alternator transients. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed upstream of DC-DC converters and LDOs to limit input voltage excursion. Use Value: Clamps to 209 V during 7.2 A surge, preventing damage to 36 V-rated input stages while maintaining system uptime. |
Use Scenario: Shielding analog outputs (e.g., 4–20 mA, 0–10 V) of pressure/temperature sensors from ESD and field wiring transients. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF typical) bidirectional shunt protector across signal and return lines. Use Value: Sub-µA leakage at 130 V standoff preserves signal accuracy; symmetrical clamping avoids DC offset in differential pairs. |
| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Surge suppression on RS-485/RS-232 data lines exposed to building-wide lightning coupling in base stations or network gateways. IC Role / Device Role / Timing Role: Primary-level TVS placed at connector entry point, ahead of isolated transceivers. Use Value: 1500 W rating handles multi-kV common-mode surges; DO-214AB footprint enables dense layout near I/O connectors. |
Use Scenario: Protecting microcontroller GPIOs and gate drivers connected to brushed DC motor commutation circuits. IC Role / Device Role / Timing Role: Fast-response (nanosecond) clamp absorbing inductive kickback from motor windings. Use Value: 209 V clamping prevents latch-up in 5 V/3.3 V logic; 1500 W rating sustains repeated switching events without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC130CA | Same VWM (130 V) and VC (209 V), but lower PPPM = 600 W; smaller SMA package (DO-214AC) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 compliance | Select only where space constraints outweigh surge energy requirements |
| SMCJ130A-E3/9AT | Unidirectional variant; identical VWM, VBR, VC, and PPPM, but marked cathode band and asymmetric conduction | Requires polarity-aware placement; not suitable for AC or floating signal paths | Choose only for DC-biased rails where reverse conduction must be blocked |
Compared with SAC130CA, the SMCJ130CA-E3/9AT delivers 2.5× higher surge energy handling in the same functional category; versus SMCJ130A-E3/9AT, it eliminates polarity dependency at no cost to clamping performance - making it the preferred choice for bidirectional or unknown-polarity protection points.

FAQ
What is the clamping voltage of the SMCJ130CA-E3/9AT under standard surge conditions?
The SMCJ130CA-E3/9AT clamps to a maximum of 209 V at 7.2 A peak pulse current under the industry-standard 10/1000 µs waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal, and represents the upper bound of voltage imposed on protected circuitry during a defined surge event. The SMCJ130CA-E3/9AT maintains this clamping performance symmetrically in both directions due to its bidirectional construction.
Is the SMCJ130CA-E3/9AT AEC-Q101 qualified?
No, the SMCJ130CA-E3/9AT is RoHS-compliant commercial-grade with E3 suffix; it is not AEC-Q101 qualified. For automotive-grade qualification, Vishay offers the SMCJ130CAHE3 variant (HE3 suffix), which carries full AEC-Q101 certification and is intended for under-hood and safety-critical vehicle systems. The SMCJ130CA-E3/9AT remains suitable for non-automotive industrial and telecom applications where AEC-Q101 is not mandated.
How does the SMCJ130CA-E3/9AT differ from the unidirectional SMCJ130A-E3/9AT?
The SMCJ130CA-E3/9AT is bidirectional with no polarity marking and symmetrical breakdown in both directions, whereas the SMCJ130A-E3/9AT is unidirectional with a visible cathode band and conducts only in reverse bias. Both share identical VWM (130 V), VBR (144–159 V), VC (209 V), and PPPM (1500 W), but the SMCJ130CA-E3/9AT enables protection of AC-coupled, floating, or polarity-unknown signal paths where the SMCJ130A-E3/9AT would fail to suppress positive transients.
What is the thermal resistance and maximum junction temperature of the SMCJ130CA-E3/9AT?
The SMCJ130CA-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted per Vishay's recommended pad layout, and a maximum operating junction temperature (TJ) of +150 °C. Its storage temperature range matches: -55 °C to +150 °C. These ratings allow reliable operation in under-hood automotive and industrial enclosures, provided board-level thermal design accounts for power dissipation during repetitive surge events.
Can the SMCJ130CA-E3/9AT be used in place of the SMCJ130A-E3/9AT without layout changes?
No - although both share the same SMC (DO-214AB) package and pin-compatible terminals, the SMCJ130CA-E3/9AT lacks polarity marking and functions bidirectionally, while the SMCJ130A-E3/9AT requires correct anode/cathode orientation. Replacing one with the other without verifying circuit topology may result in unintended conduction or ineffective protection. The SMCJ130CA-E3/9AT is not a drop-in replacement unless the application inherently benefits from bidirectional clamping and layout accommodates unmarked orientation.
