Product details
Overview
SMAJ130A-13-F from Diodes Incorporated is a unidirectional 400W surface-mount transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power lines and signal interfaces. It features a 130V reverse standoff voltage (VRWM), 144–159V breakdown range (VBR), 209V max clamping voltage at 1.9A peak pulse current (IPP), and operates from –55°C to +150°C - used in automotive infotainment power rails and industrial PLC I/O modules.
For engineers reviewing the SMAJ130A-13-F datasheet, SMAJ130A-13-F pinout, SMAJ130A-13-F application, or SMAJ130A-13-F equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD tolerance, 8.3ms surge current handling (IFSM = 40A), thermal derating above +25°C, and compatibility with automated SMT reflow profiles for SMA package.
Technical Context
This TVS diode employs glass-passivated junction construction for stable avalanche performance and fast response (<1 ns) to ESD and lightning-induced transients. Its unidirectional configuration provides low-leakage forward conduction path while clamping reverse surges - critical for protecting downstream regulators and microcontrollers on 12V/24V systems.
The device complies with IEC 61000-4-2 (±30kV contact) and IEC 61000-4-5 (4kV 8/20μs) immunity standards when properly laid out. Clamping behavior is characterized under standardized 10/1000μs waveform per REA, with peak power derated linearly above +25°C ambient per Fig. 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W - sustains single 10/1000μs surge without failure; defines maximum transient energy absorption capability |
| Reverse Standoff Voltage (VRWM) | 130V - maximum continuous DC or RMS voltage before significant leakage; sets upper limit for normal operating bus voltage |
| Breakdown Voltage (VBR) | 144–159V @ 1.0mA - guaranteed avalanche onset range; ensures reliable triggering above VRWM with margin |
| Max Clamping Voltage (VC) | 209V @ IPP = 1.9A - peak voltage seen by protected circuit during rated surge; determines minimum required IC overvoltage rating |
| Peak Forward Surge Current (IFSM) | 40A @ 8.3ms half-sine - handles repetitive line-frequency surges (e.g., AC rectifier turn-on spikes) |
| Operating Temperature | –55°C to +150°C - supports under-hood automotive and industrial environments without derating |
| Package | SMA (DO-214AC) - industry-standard 2-pin SMT footprint; compatible with IPC-7351B generic land pattern |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with UL 94V-0 flammability rating, cathode band marking for polarity identification. Weight: 0.064g. Moisture sensitivity level: MSL 1 (unlimited floor life).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connects to lower-potential side of protected line (e.g., GND or return path); conducts during positive transients in unidirectional mode |
| Cathode | Avalanche clamping terminal | Connects to higher-potential side (e.g., 130V rail); initiates controlled breakdown during reverse overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| 400W peak pulse power | Enables robust protection against ISO 7637-2 Pulse 1/2a/5a transients in 12V automotive systems without derating |
| Glass-passivated die | Ensures stable VBR and low leakage (<5µA at VRWM) across temperature and lifetime, critical for battery-backed circuits |
| Fast response time | <1 ns reaction to ESD events - prevents latch-up or damage in high-speed interface ICs like CAN or LIN transceivers |
| RoHS-compliant & halogen-free | Meets automotive PPAP requirements (AEC-Q101 qualified variant available); supports green manufacturing mandates |
| SMA package | Enables high-density PCB layout with proven thermal performance; compatible with standard reflow profiles (J-STD-020 MSL 1) |
Applications
| Automotive Infotainment Power Rail | Industrial PLC Digital Input Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-TP from Microchip | Same VRWM (130V), identical SMA package, but 215V VC @ 1.9A (6V higher clamping) | Marginally reduced protection level for sensitive 3.3V logic powered from same rail | Select if cost-sensitive and clamping margin allows; verify downstream IC absolute max ratings |
| P6SMB130A from Vishay | Same electrical specs (VRWM=130V, VC=209V), but P6SMB package has larger thermal mass and 1.5W steady-state rating vs. 1.0W | Better thermal stability in high-ambient industrial enclosures with limited airflow | Prefer for continuous surge exposure scenarios; requires revised PCB pad layout |
Compared with SMAJ130A-13-F, SMAJ130A-TP offers lower cost but sacrifices 6V clamping margin, while P6SMB130A trades compactness for superior thermal endurance - choice depends on whether board space or thermal reliability dominates the design priority.

FAQ
What is the maximum clamping voltage of SMAJ130A-13-F at its rated peak pulse current?
The maximum clamping voltage (VC) is 209V when subjected to a 10/1000μs waveform with a peak pulse current (IPP) of 1.9A, measured per REA standard. This value is guaranteed across the full operating temperature range (–55°C to +150°C) and defines the highest voltage stress imposed on protected circuitry during surge events.
Is SMAJ130A-13-F suitable for bidirectional signal line protection?
No - SMAJ130A-13-F is unidirectional, indicated by the absence of "C" in its part number. Bidirectional operation requires the "C" suffix (e.g., SMAJ130CA-13-F), which lacks polarity marking and clamps symmetrically for AC or data-line applications. Using this part on bidirectional lines risks forward conduction and unintended current paths.
How does the SMA package affect thermal performance in high-power surge conditions?
The SMA (DO-214AC) package delivers 1.0W steady-state power dissipation at TL = +75°C, with thermal resistance from junction-to-lead (RθJL) ~25°C/W. During 400W transient events, heat is absorbed capacitively by the die and lead frame; sustained surge repetition requires PCB copper area ≥40 mm² per pad and thermal vias to internal ground planes to prevent localized overheating.
Does SMAJ130A-13-F meet AEC-Q101 qualification requirements?
The standard SMAJ130A-13-F is not AEC-Q101 qualified; however, Diodes offers an automotive-compliant variant designated SMAJ130AQ-13-F, manufactured in IATF 16949-certified facilities and qualified per AEC-Q101. For automotive production, the "Q" suffix version must be specified to ensure change control, PPAP documentation, and guaranteed reliability testing.
