Product details
Overview
SMCJ130A-M3/57T from Vishay General Semiconductor is a unidirectional 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), 144–159 V breakdown voltage (VBR) at 1 mA, 209 V maximum clamping voltage (VC) at 7.2 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial motor drives and automotive ECUs.
For engineers reviewing the SMCJ130A-M3/57T datasheet, SMCJ130A-M3/57T pinout, SMCJ130A-M3/57T application, or SMCJ130A-M3/57T equivalent, key selection criteria include clamping voltage margin relative to system rail, thermal resistance (RθJA = 75 °C/W), unidirectional polarity marking, halogen-free RoHS compliance (M3 suffix), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ130A-M3/57T operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response to ESD and lightning-induced surges. Its low incremental surge resistance ensures stable clamping under repetitive transient stress, while MSL Level 1 rating supports lead-free reflow up to 260 °C peak.
Designed for unidirectional protection only, it exhibits 1.0 μA max reverse leakage at 130 V and a positive temperature coefficient of VBR (+0.108 %/°C), enabling predictable voltage drift over -55 °C to +150 °C operating range. The cathode band denotes polarity, and no marking is applied to bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 130 V - Maximum continuous reverse voltage before significant leakage; sets upper limit for protected line voltage. |
| VBR (Breakdown Voltage) | 144–159 V at 1 mA - Confirmed avalanche initiation range; defines minimum clamping threshold under transient conditions. |
| VC (Clamping Voltage) | 209 V at IPPM = 7.2 A (10/1000 μs) - Peak voltage seen by downstream circuit during worst-case surge; determines required IC voltage margin. |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capacity for standardized 10/1000 μs surge; validates suitability for IEC 61000-4-5 Level 4 immunity. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on recommended 8.0 mm × 8.0 mm pad layout; informs derating above 25 °C ambient. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive or high-temperature industrial enclosures. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm body and 2.62 mm height; compatible with IPC-7351B footprint. |
Pinout & Package
SMCJ130A-M3/57T uses the SMC (DO-214AB) package: 2-terminal surface-mount device with cathode band marking on one end. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode-side connection point for reverse-biased TVS operation | Connected to protected line (e.g., 130 V rail); clamps when line voltage exceeds VBR relative to ground. |
| Anode (non-banded end) | Reference terminal | Typically tied to system ground or low-impedance return path; forms clamping loop with cathode during surge event. |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free, RoHS-compliant construction (M3 suffix) | Meets environmental compliance requirements for automotive and industrial OEMs without compromising surge robustness. |
| Low incremental surge resistance | Enables tighter clamping voltage tolerance across varying surge amplitudes - critical for protecting 150 V-rated MOSFETs. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profile (peak 260 °C), eliminating bake-out steps in high-volume SMT assembly. |
| 1500 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 combination wave testing at 2 Ω source impedance for industrial control inputs. |
| Glass passivated chip junction | Ensures long-term reliability and stable VBR drift under thermal cycling and humidity exposure in harsh environments. |
Applications
| Industrial Motor Drive DC Bus Protection | Automotive Body Control Module (BCM) Power Input |

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 | Lower PPPM (400 W), same VWM/VBR/VC, SMA package (smaller thermal mass) | Not suitable for IEC 61000-4-5 Level 4; limited to low-energy signal-line protection | Select only for space-constrained PCBs where surge energy is ≤200 W and RθJA budget allows ≥120 °C/W derating. |
| SMCJ130CA-M3/57T | Bidirectional variant; identical VWM/VBR/VC ratings but symmetrical conduction in both polarities | Required for AC-coupled or floating differential lines (e.g., RS-485, CAN FD) where polarity reversal occurs | Choose when protecting bidirectional data lines or transformer-coupled interfaces - not a drop-in replacement due to polarity symmetry. |
Compared with SMAJ130A-E3/57T and SMCJ130CA-M3/57T, the SMCJ130A-M3/57T uniquely balances 1500 W surge capacity, 130 V standoff, and halogen-free compliance in the SMC footprint - making it optimal for high-reliability DC bus and automotive power rail protection where unidirectional clamping suffices.

FAQ
What is the maximum clamping voltage of the SMCJ130A-M3/57T under standard test conditions?
The SMCJ130A-M3/57T has a maximum clamping voltage (VC) of 209 V when subjected to a 10/1000 μs waveform with a peak pulse current (IPPM) of 7.2 A. This value is measured at TA = 25 °C on the recommended 8.0 mm × 8.0 mm copper pad layout. The SMCJ130A-M3/57T maintains this clamping performance across its specified operating temperature range, ensuring consistent protection for downstream 150 V-rated components.
Does the SMCJ130A-M3/57T meet automotive qualification standards?
The SMCJ130A-M3/57T is halogen-free and RoHS-compliant (M3 suffix) but is not AEC-Q101 qualified. For automotive applications requiring AEC-Q101 certification, Vishay offers the SMCJ130A-HM3_X variant - which shares identical electrical characteristics but adds stress testing per AEC-Q101. The SMCJ130A-M3/57T remains suitable for non-safety-critical automotive subsystems where commercial-grade reliability is acceptable.
How does the thermal resistance of the SMCJ130A-M3/57T affect its power derating?
The SMCJ130A-M3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the minimum recommended 8.0 mm × 8.0 mm copper pads. At 70 °C ambient, its power dissipation must be derated to ~3.3 W to maintain TJ ≤ 150 °C. This directly impacts sustained surge repetition rate and requires careful PCB layout - the SMCJ130A-M3/57T relies on copper area, not heatsinks, for thermal management.
Can the SMCJ130A-M3/57T be used in bidirectional signal protection?
No - the SMCJ130A-M3/57T is strictly unidirectional, with a cathode band indicating polarity. Using it on AC or floating differential lines risks forward conduction and failure. For bidirectional protection, the SMCJ130CA-M3/57T is the functionally matched variant with symmetrical breakdown in both directions. The SMCJ130A-M3/57T must be oriented correctly with cathode toward the protected line and anode to ground.
What is the reverse leakage current specification for the SMCJ130A-M3/57T at rated standoff voltage?
At its rated standoff voltage (VWM) of 130 V and TA = 25 °C, the SMCJ130A-M3/57T exhibits a maximum reverse leakage current (ID) of 1.0 μA. This low leakage ensures minimal power loss in standby mode and avoids false triggering in high-impedance sensing circuits. The SMCJ130A-M3/57T maintains this specification across its full operating temperature range, with leakage increasing predictably per the device's temperature coefficient.
