Product details
Overview
SMDJ130CA from Alpha & Omega Semiconductor is a bi-directional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It features a 130 V reverse stand-off voltage (VRWM), 144–159 V breakdown voltage (VBR) at 1 mA, 209 V maximum clamping voltage (VC) at 14.4 A peak pulse current, and 3000 W peak pulse power dissipation on a 10/1000 µs waveform - deployed in industrial motor drives and telecom power supplies.
For engineers reviewing the SMDJ130CA datasheet, pinout, applications, or equivalent options, key selection criteria include clamping performance under 10/1000 µs surges, bi-directional symmetry for AC-coupled or floating bus protection, thermal resistance (RθJA = 75 °C/W), and DO-214AB package compatibility with high-current PCB layouts.
Technical Context
The SMDJ130CA operates as a bi-directional avalanche diode, exhibiting symmetrical clamping behavior in both polarities with identical VBR min/max (144–159 V) and VC (209 V) values. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (IR ≤ 2.0 µA @ 130 V), while the 1.0 ps response time enables protection against fast ESD and lightning-induced transients.
Thermally, it supports operation from –55 °C to +150 °C junction temperature, with RθJL = 15 °C/W enabling effective heat transfer to copper pads (8.0 mm × 8.0 mm per terminal). The device is rated for non-repetitive 8.3 ms half-sine surge currents up to 300 A and complies with MSL Level 1 reflow (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin. |
| VBR @ IT=1 mA | 144–159 V - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM=14.4 A | 209 V - Clamped voltage under 10/1000 µs surge; determines protected circuit's maximum stress level. |
| PPPM | 3000 W - Peak pulse power handling on standard 10/1000 µs waveform; validates robustness against IEC 61000-4-5 surges. |
| IR @ VRWM | ≤2.0 µA - Reverse leakage at rated stand-off; guarantees minimal standby power loss and signal integrity. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in enclosed industrial enclosures without forced cooling. |
| RθJA | 75 °C/W - Thermal resistance to ambient; requires ≥8 mm² copper pad per terminal for full power derating. |
Pinout & Package
DO-214AB (SMC J-Bend) surface-mount package with molded plastic case and matte tin lead-free plating. Cathode band denotes polarity for uni-directional variants; bi-directional SMDJ130CA has no polarity marking and functions identically in either orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (Bidirectional) | Surge current path | Both terminals serve as symmetrical avalanche junctions; no fixed anode/cathode - interchangeable in layout. |
| Case / Body | Thermal conduction path | Plastic body transfers heat to PCB copper pads; requires 8.0 mm × 8.0 mm solder mask defined copper per terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping symmetry | Identical VBR (144–159 V) and VC (209 V) in both directions - eliminates polarity concerns in AC or floating-bus protection. |
| Fast transient response | <1.0 ps response time from 0 V to breakdown - captures sub-nanosecond ESD events before downstream IC damage occurs. |
| Glass-passivated junction | Stable VBR tolerance and low IR drift over temperature and lifetime - critical for long-term reliability in unattended systems. |
| MSL Level 1 rating | Compatible with standard Pb-free reflow profiles up to 260 °C peak - enables drop-in use in automated SMT assembly lines. |
| UL 94V-0 flammability | Self-extinguishing plastic housing - meets safety requirements for enclosed power supply and telecom equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ130CA | Same DO-214AB package, 130 V VRWM, but lower PPPM (400 W vs. 3000 W); VBR tighter (144–153 V). | Rated for lower-energy transients (IEC 61000-4-2 ESD only); unsuitable for IEC 61000-4-5 line surges. | Select SMDJ130CA when protecting high-power DC rails requiring 3000 W surge handling - SMAJ130CA fits space-constrained low-energy nodes. |
| Vishay SMF130CA | DO-214AA (SMA) package, smaller footprint; same 130 V VRWM but only 200 W PPPM and 253 V VC @ 0.8 A. | Limited to low-current signal lines; cannot handle motor drive or inverter-level surge currents. | Choose SMDJ130CA for industrial-grade 3000 W clamping; SMF130CA suits compact PCBs with sub-1 A surge exposure. |

FAQ
What is the clamping voltage of the SMDJ130CA under a 10/1000 µs surge?
The SMDJ130CA exhibits a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current of 14.4 A on a 10/1000 µs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream components remain within their absolute maximum ratings.
Is the SMDJ130CA unidirectional or bidirectional?
The SMDJ130CA is a bi-directional transient voltage suppressor, meaning it provides symmetrical clamping in both polarities. Unlike unidirectional variants (e.g., SMDJ130A), the CA suffix confirms identical electrical characteristics - including VBR (144–159 V) and VC (209 V) - in either direction, making it ideal for AC-coupled interfaces or floating DC buses where polarity is undefined.
What package type does the SMDJ130CA use, and what are its mounting requirements?
The SMDJ130CA uses the DO-214AB (SMC J-Bend) surface-mount package. It requires 8.0 mm × 8.0 mm solder mask defined copper pads per terminal for thermal performance, and is compatible with MSL Level 1 reflow profiles (peak 260 °C). No polarity marking is present, reflecting its bi-directional functionality.
How does the SMDJ130CA compare to the SMAJ130CA in surge handling capability?
The SMDJ130CA delivers 3000 W peak pulse power on a 10/1000 µs waveform, whereas the SMAJ130CA is rated for only 400 W. This 7.5× difference means the SMDJ130CA is qualified for IEC 61000-4-5 line surge testing, while the SMAJ130CA is limited to lower-energy IEC 61000-4-2 ESD protection - a critical distinction for industrial power rail applications.
What is the maximum junction temperature and thermal resistance of the SMDJ130CA?
The SMDJ130CA has a maximum junction temperature (TJ max) of +150 °C and a typical thermal resistance from junction to ambient (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads. Its junction-to-lead resistance (RθJL) is 15 °C/W, supporting efficient heat transfer to the PCB - essential for sustained operation in enclosed industrial environments.
