Product details
Overview
SMCJ130A-M3/9AT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 130 V standoff voltage (VWM), 144–159 V breakdown range (VBR at 1 mA), 209 V maximum clamping voltage (VC) at 7.2 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power modules, industrial motor drives, and telecom interface circuits.
For engineers reviewing the SMCJ130A-M3/9AT datasheet, SMCJ130A-M3/9AT pinout, SMCJ130A-M3/9AT application, or SMCJ130A-M3/9AT equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance (RθJA = 75 °C/W), halogen-free RoHS compliance (M3 suffix), and unidirectional polarity marking for correct PCB orientation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 130 V, it avalanches into low-impedance conduction to divert surge energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the SMC package supports automated placement and meets MSL level 1 per J-STD-020.
The device is rated for continuous operation from −55 °C to +150 °C junction temperature, with 6.5 W power dissipation on infinite heatsink at 50 °C ambient. Its 0.057 %/°C VBR temperature coefficient enables predictable clamping behavior across wide thermal ranges in engine control units and power supply front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 130 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR (Breakdown) | 144–159 V at 1 mA - Confirmed avalanche onset range defining minimum protection threshold |
| VC (Clamping) | 209 V at 7.2 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge |

| Package | SMC (DO-214AB) - Industry-standard 2-pin surface-mount outline with cathode band marking |
Pinout & Package
SMCJ130A-M3/9AT uses the SMC (DO-214AB) package: a rectangular surface-mount case measuring 7.75 mm × 6.22 mm × 2.62 mm with matte tin-plated leads solderable per J-STD-002. Polarity is marked by a cathode band on the body end; the banded terminal is the cathode (K), and the opposite is the anode (A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased terminal | Connected to protected line (e.g., +12 V rail); conducts surge current to ground when overvoltage occurs |
| Anode (non-banded end) | Reference terminal | Typically tied to system ground or low-side return path; completes clamping current loop |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free, RoHS-compliant construction | M3 suffix confirms full compliance with environmental regulations and JEDEC JESD201 Class 2 whisker resistance |
| Low incremental surge resistance | Enables tighter clamping (VC = 209 V) and lower let-through energy during transients |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking - simplifies SMT manufacturing |
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under repeated surge stress |
| 1500 W peak pulse power | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity in industrial and automotive applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-M3/57T | Lower PPPM (600 W), SMB package (smaller footprint, higher RθJA = 110 °C/W) | Suitable for space-constrained, lower-energy surge environments (e.g., consumer USB ports) | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 2 |
| SMCJ130CA-M3/9AT | Bidirectional variant; same VWM, VBR, VC, and PPPM but symmetrical clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal may occur | Choose only if bidirectional protection is mandated - not a drop-in replacement due to polarity architecture |
Compared with SMBJ130A-M3/57T and SMCJ130CA-M3/9AT, the SMCJ130A-M3/9AT delivers optimal balance of high-energy clamping (1500 W), thermal performance (RθJA = 75 °C/W), and unidirectional precision for DC power rail protection - making it preferred for automotive and industrial systems requiring robust single-polarity surge immunity.

FAQ
What is the clamping voltage of SMCJ130A-M3/9AT at its rated peak pulse current?
The SMCJ130A-M3/9AT has a maximum clamping voltage (VC) of 209 V when subjected to its specified peak pulse current of 7.2 A using the 10/1000 µs waveform. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ130A-M3/9AT maintains this clamping performance across its full operating temperature range.
Is SMCJ130A-M3/9AT suitable for automotive applications?
Yes, the SMCJ130A-M3/9AT is halogen-free and RoHS-compliant (M3 suffix), and belongs to the AEC-Q101-qualified SMCJ family - though the exact M3/9AT variant is commercial-grade. For certified automotive use, Vishay offers the HM3 suffix (e.g., SMCJ130A-HM3/9AT), which adds AEC-Q101 qualification. The SMCJ130A-M3/9AT shares identical electrical and thermal specs, making it suitable for non-safety-critical automotive subsystems where qualification is not mandated.
What does the "M3" suffix mean in SMCJ130A-M3/9AT?
The "M3" suffix in SMCJ130A-M3/9AT indicates halogen-free, RoHS-compliant construction meeting JEDEC JESD201 Class 2 whisker resistance requirements. It denotes commercial-grade temperature rating (−55 °C to +150 °C) and distinguishes the part from E3 (RoHS-compliant, non-halogen-free) and HM3 (AEC-Q101 qualified + halogen-free) variants. The SMCJ130A-M3/9AT is fully compatible with lead-free reflow processes and standard SMT assembly lines.
How is polarity identified on the SMCJ130A-M3/9AT package?
The SMCJ130A-M3/9AT uses a unidirectional configuration with polarity marked by a visible cathode band on one end of the SMC (DO-214AB) package. The banded terminal is the cathode (K), intended to be connected toward the protected line (e.g., +130 V rail), while the opposite, unmarked end is the anode (A), typically routed to ground. This marking is laser-etched or molded and remains legible after reflow soldering. The SMCJ130A-M3/9AT must be oriented correctly on PCB to ensure proper clamping function.
What is the thermal resistance of SMCJ130A-M3/9AT, and how does it affect PCB layout?
The SMCJ130A-M3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This value directly impacts safe power derating: at 50 °C ambient, its 6.5 W power dissipation limit requires adequate copper area and possible internal layer thermal vias. Reducing pad size increases RθJA, risking thermal runaway during repetitive surges. Layout guidance for the SMCJ130A-M3/9AT is defined in Vishay's recommended mounting pad dimensions.
