Product details
Overview
SMCJ130CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection 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 (10/1000 µs waveform), commonly deployed in automotive power rail and industrial sensor interface protection.
For engineers reviewing the SMCJ130CA-E3/57T datasheet, SMCJ130CA-E3/57T pinout, SMCJ130CA-E3/57T application, or SMCJ130CA-E3/57T equivalent, key selection criteria include bidirectional clamping symmetry, low incremental surge resistance, AEC-Q101 qualification status, and compatibility with automated SMT placement on 8 mm × 8 mm copper pads.
Technical Context
This device operates as a voltage-clamping protector using an avalanche breakdown mechanism, with symmetrical bidirectional conduction enabling suppression of both positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while MSL Level 1 rating confirms suitability for standard reflow profiles up to 260 °C peak.
The thermal design relies on low RθJL (15 °C/W) to dissipate surge energy into PCB copper, and its 75 °C/W junction-to-ambient rating assumes minimum recommended pad layout. It meets UL 497B recognition (QVGQ2) and complies with ANSI/IEEE C62.35 surge test standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 144 V / 159 V at IT = 1 mA - Confirmed breakdown threshold range under standardized test conditions |
| VC | 209 V at IPPM = 7.2 A - Clamped voltage seen by protected circuit during full 1500 W surge event |
| PPPM | 1500 W (10/1000 µs) - Peak surge power handling capacity per single transient event |
| IPPM | 7.2 A - Peak surge current corresponding to VC = 209 V under standard waveform |

| Package | SMC (DO-214AB) - Surface-mount outline with 8.0 mm × 8.0 mm thermal pad requirement for rated power dissipation |
Pinout & Package
SMCJ130CA-E3/57T uses a 2-terminal SMC (DO-214AB) package with no polarity marking-consistent with bidirectional construction. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; symmetric conduction path |
| Terminal 2 | Anode/Cathode (bidirectional) | Electrically identical to Terminal 1; no functional distinction-device has no polarity marking |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines or ungrounded differential signals without polarity concerns |
| 1500 W peak pulse power | Withstands high-energy transients such as ISO 7637-2 Pulse 5a (load dump) in automotive 12 V systems |
| AEC-Q101 qualified option | RoHS-compliant SMCJ130CA-HE3 variant available for automotive-grade reliability validation |
| Low clamping ratio (VC/VBR) | ~1.45 - Minimizes overvoltage stress on downstream ICs during surge events |
| MSL Level 1 rating | Supports standard lead-free reflow without moisture sensitivity preconditioning |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Suppresses load dump transients (up to 120 V, 400 ms) on 12 V battery-fed ECUs and body control modules. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed between power rail and ground, responding within <1 ps to limit overvoltage. Use Value: Prevents latch-up or permanent damage to microcontrollers and CAN transceivers by holding rail voltage ≤209 V during surge. | Use Scenario: Protects analog output lines (e.g., 4–20 mA current loop) from ESD and inductive switching noise in factory automation PLCs. IC Role / Device Role / Timing Role: Bidirectional shunt element across signal and return, clamping ±209 V spikes without DC bias dependency. Use Value: Maintains signal integrity and prevents ADC saturation or op-amp input stage damage during field wiring faults. |
| Telecom DC Power Input Protection | Consumer Appliance Motor Drive Interface |
Use Scenario: Guards PoE-powered equipment inputs against surges induced by lightning-induced coupling on Ethernet cabling. IC Role / Device Role / Timing Role: Primary surge limiter on 48 V DC input, coordinated with upstream MOVs and downstream filtering. Use Value: Limits transient overshoot to safe levels for DC-DC controllers and PMICs, preserving system uptime and certification compliance. | Use Scenario: Shields microcontroller GPIOs and gate drivers from back-EMF spikes generated by brushed DC motors in smart home appliances. IC Role / Device Role / Timing Role: Fast-response clamp across motor terminals or driver outputs, absorbing inductive kickback energy. Use Value: Eliminates need for snubber RC networks, reducing BOM count and board space while maintaining IEC 61000-4-4 level 4 immunity. |
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 | Lower PPPM (600 W), same VWM/VC, smaller SMA package | Not suitable for ISO 7637-2 Pulse 5a; limited to lower-energy ESD/lightning events | Select when board space is constrained and surge threat level is reduced (e.g., secondary-side protection). |
| SMCJ130A-E3/57T | Unidirectional version; identical VWM, VBR, VC, and PPPM, but requires correct polarity orientation | Applicable only where DC bias is present and polarity is fixed (e.g., +12 V supply rail with ground reference) | Choose if system architecture guarantees unidirectional transients and polarity alignment can be assured during layout. |
Compared with SAC130CA and SMCJ130A-E3/57T, the SMCJ130CA-E3/57T uniquely delivers 1500 W bidirectional clamping in SMC package-enabling robust, polarity-agnostic protection for high-threat environments like automotive front-end power distribution and industrial fieldbus interfaces.

FAQ
What does the "CA" suffix indicate in SMCJ130CA-E3/57T?
The "CA" suffix denotes a bidirectional configuration: SMCJ130CA-E3/57T clamps voltage transients of either polarity symmetrically, unlike unidirectional variants (e.g., SMCJ130A). This eliminates polarity marking requirements and enables use on AC-coupled or floating signal lines. The SMCJ130CA-E3/57T achieves identical VBR, VC, and PPPM performance in both directions per Vishay Document 88394.
Is SMCJ130CA-E3/57T AEC-Q101 qualified?
The base SMCJ130CA-E3/57T is RoHS-compliant commercial-grade; however, the AEC-Q101 qualified version is designated SMCJ130CA-HE3 (with "HE3" suffix). Per Vishay's ordering table, HE3 variants undergo extended stress testing for automotive applications. SMCJ130CA-E3/57T itself is not AEC-Q101 certified, but shares identical electrical and thermal specs with the HE3 variant except for qualification documentation and traceability.
What is the maximum clamping voltage of SMCJ130CA-E3/57T and under what test condition?
The maximum clamping voltage (VC) of SMCJ130CA-E3/57T is 209 V, measured at IPPM = 7.2 A using a 10/1000 µs double-exponential surge waveform. This value is guaranteed per Vishay's Electrical Characteristics table (Document 88394, page 2) and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can SMCJ130CA-E3/57T replace SMCJ130A-E3/57T in an existing design?
SMCJ130CA-E3/57T can replace SMCJ130A-E3/57T only if the application involves bidirectional threats or lacks defined polarity-since the CA version has no cathode marking and conducts identically in both directions. However, it is not a drop-in replacement for unidirectional layouts relying on polarity-aware placement; doing so may compromise protection if forward-biased conduction is unintended. Always verify system-level surge directionality before substitution.
What PCB pad layout is required to achieve the rated 1500 W surge capability for SMCJ130CA-E3/57T?
To achieve full 1500 W peak pulse power rating, SMCJ130CA-E3/57T must be mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as specified in Vishay Document 88394. Smaller pads reduce thermal dissipation, derating both IPPM and PPPM; the device's RθJL = 15 °C/W assumes this minimum copper area. Layouts using smaller pads require consulting Fig. 2 (derating curve) for adjusted surge ratings.
