Product details
Overview
SMCJ130CA-M3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 1500 W peak pulse power rating, 130 V standoff voltage (VWM), and 209 V clamping voltage (VC) 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 SMCJ130CA-M3/9AT datasheet, SMCJ130CA-M3/9AT pinout, SMCJ130CA-M3/9AT application, or SMCJ130CA-M3/9AT equivalent, key selection criteria include bidirectional clamping capability, 1500 W 10/1000 µs surge rating, halogen-free RoHS-compliant construction, AEC-Q101 qualification eligibility, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This TVS diode operates as a voltage-clamping protection device that remains non-conductive below its reverse standoff voltage (VWM = 130 V) and rapidly transitions to low-impedance conduction when transient voltages exceed its breakdown threshold (VBR min = 144 V, max = 159 V). Its bidirectional symmetry ensures identical clamping behavior in both polarities, eliminating polarity sensitivity in AC-coupled or floating signal paths.
The device features glass-passivated junction construction for stable leakage performance, low incremental surge resistance for minimal voltage overshoot during fast transients, and thermal design optimized for junction-to-lead resistance of 15 °C/W - enabling effective heat dissipation under repetitive surge conditions when mounted per recommended 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 144 V / 159 V - Breakdown occurs within this range at 1 mA test current; defines turn-on threshold |
| VC @ IPPM | 209 V - Clamped voltage across device at 7.2 A peak pulse current (10/1000 µs waveform) |
| PPPM | 1500 W - Peak pulse power handling capacity under standardized surge waveform |
| ID @ VWM | 1.0 µA - Reverse leakage current at rated standoff voltage; ensures minimal standby power loss |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments |
| Package | SMC (DO-214AB) - Surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height |
Pinout & Package
SMCJ130CA-M3/9AT uses the SMC (DO-214AB) package: a two-terminal, bidirectional surface-mount device with no polarity marking. The case is molded compound meeting UL 94 V-0 flammability rating; terminals are matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 1500 W peak pulse power | Withstands high-energy transients such as ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 Combination Wave (10/700 µs) |
| Halogen-free & RoHS-compliant (M3 suffix) | Meets environmental compliance requirements for automotive and industrial end equipment without compromising surge robustness |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and reflow soldering at peak temperature up to 260 °C without preconditioning |
| Low clamping ratio (VC/VBR ≈ 1.41) | Minimizes overvoltage stress on protected downstream components during surge events |

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 (130 V), smaller SMA package | Not suitable for high-energy automotive load dump; limited to consumer-grade surge immunity | Select only for space-constrained, lower-risk applications where 1500 W rating is unnecessary |
| SMCJ130A-M3/9AT | Unidirectional version; includes cathode band marking; identical VWM, VBR, VC, and PPPM | Requires polarity-aware layout; unsuitable for AC or floating differential signals | Choose only when circuit topology guarantees consistent polarity and grounding reference |
Compared with SAC130CA and SMCJ130A-M3/9AT, the SMCJ130CA-M3/9AT uniquely delivers 1500 W bidirectional clamping in SMC package - making it the sole option among the three for high-energy, polarity-agnostic protection in automotive and industrial power rails.

FAQ
What is the clamping voltage of SMCJ130CA-M3/9AT at its rated peak pulse current?
The SMCJ130CA-M3/9AT has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current of 7.2 A under the standard 10/1000 µs waveform. This value is measured across the device terminals during surge conduction and defines the upper voltage limit imposed on protected circuitry - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings during transient events. The SMCJ130CA-M3/9AT maintains this clamping performance bidirectionally.
Is SMCJ130CA-M3/9AT suitable for automotive applications requiring AEC-Q101 qualification?
The SMCJ130CA-M3/9AT itself is not AEC-Q101 qualified, but Vishay offers AEC-Q101-qualified versions under ordering codes HM3_X (e.g., SMCJ130CAHM3_A/I). The M3 suffix indicates halogen-free RoHS compliance, while AEC-Q101 qualification requires the additional HM3_X designation and specific revision coding. Engineers must select the HM3_X variant explicitly for automotive-grade deployment; the SMCJ130CA-M3/9AT is intended for commercial/industrial use with AEC-Q101-ready process flow.
How does the bidirectional nature of SMCJ130CA-M3/9AT affect PCB layout compared to unidirectional TVS diodes?
The SMCJ130CA-M3/9AT has no polarity marking and functions identically in both directions, eliminating the need for orientation verification during automated placement and removing risk of reverse installation. Unlike unidirectional variants (e.g., SMCJ130A-M3/9AT) that require cathode band alignment, the SMCJ130CA-M3/9AT simplifies layout for AC-coupled lines, differential buses like RS-485, or floating grounds - reducing assembly errors and enabling symmetric routing. Its DO-214AB footprint remains identical across both types.
What is the thermal resistance profile of SMCJ130CA-M3/9AT, and how does it impact derating?
The SMCJ130CA-M3/9AT has a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W and junction-to-ambient (RθJA) of 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads. At ambient temperatures above 25 °C, its peak pulse power must be derated per Figure 2 in the datasheet - e.g., at 85 °C ambient, PPPM drops to ~1100 W. Proper pad sizing and copper pour area directly influence sustained surge capability and thermal recovery between events.
Does SMCJ130CA-M3/9AT meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, the SMCJ130CA-M3/9AT meets MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can withstand peak reflow temperatures up to 260 °C without baking or dry-pack requirements. This is enabled by its robust molding compound and glass-passivated chip construction. The device is fully compatible with standard lead-free soldering profiles used in high-volume SMT manufacturing, supporting reliable assembly without moisture-related defects like popcorning or delamination.
