Product details
Overview
SMA6J13A from Taiwan Semiconductor is a 600W surface-mount transient voltage suppressor (TVS) diode with a working standoff voltage of 13 V, breakdown voltage range 14.4–15.9 V, and clamping voltage of 20.4 V at 29.4 A peak pulse current; used for surge protection in DC/DC converters and power adapters.
For engineers reviewing the SMA6J13A datasheet, SMA6J13A pinout, SMA6J13A application, or SMA6J13A equivalent, key selection factors include its DO-214AC (SMA) package, 10/1000 µs waveform rating, ISO 7637-2 compliance, junction temperature range (−55°C to +175°C), and low-profile automated placement capability.
Technical Context
This unidirectional TVS diode operates as a clamping device in reverse-bias mode, triggered when transient voltage exceeds its breakdown threshold (VBR = 14.4–15.9 V at IT = 1 mA). It delivers 600 W peak pulse power under standardized 10/1000 µs waveform conditions and maintains clamping voltage ≤20.4 V at 29.4 A.
Its glass-passivated junction ensures stable leakage performance (IR ≤ 1.0 µA at VWM = 13 V), fast response time (<1.0 ps), and robustness against repetitive surges per JESD201 Class 2 whisker testing and moisture sensitivity level 1 (J-STD-020).
Key Specifications

IC Role / Device Role: Secondary-side TVS on DC output rail to prevent overvoltage damage to connected devices during no-load or fault conditions. Use Value: Low 1.0 µA leakage at 13 V minimizes standby power draw; RoHS- and halogen-free construction meets global regulatory mandates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J13CA | Bidirectional variant; symmetric clamping for AC-coupled or floating lines | Required where bidirectional transients (e.g., data lines, antenna ports) must be suppressed | Select SMA6J13CA only if circuit lacks defined polarity or requires symmetrical protection |
| SMB6J13A | Larger DO-214AA (SMB) package; same electrical specs but higher thermal mass and 1.0 W steady-state dissipation | Better suited for high-temperature environments or frequent surge events requiring enhanced thermal endurance | Choose SMB6J13A when board layout allows larger footprint and thermal derating margins are critical |
Compared with SMA6J13A, SMA6J13CA adds bidirectional clamping at the cost of polarity-specific optimization, while SMB6J13A trades compactness for improved thermal resilience-both require PCB redesign and are not drop-in replacements.

FAQ
What is the maximum clamping voltage of the SMA6J13A under standard test conditions?
The SMA6J13A has a maximum clamping voltage (VC) of 20.4 V when subjected to its rated peak pulse current of 29.4 A using the 10/1000 µs waveform. This value is measured per JEDEC standards and guarantees that downstream circuitry sees no more than 20.4 V during a defined surge event, making SMA6J13A suitable for protecting 12 V systems with adequate voltage margin.
Is the SMA6J13A unidirectional or bidirectional?
The SMA6J13A is a unidirectional transient voltage suppressor, designed for use in polarity-defined DC circuits. Its cathode band indicates the terminal to be connected toward the protected line, with the anode grounded. For bidirectional protection, the SMA6J13CA variant must be selected instead-SMA6J13A does not provide symmetrical clamping behavior.
Does the SMA6J13A meet automotive surge immunity standards?
Yes, the SMA6J13A meets ISO 7637-2 requirements for Pulse 1, 2a, 2b, 3a, and 3b, making it suitable for 12 V automotive power network protection. Its 600 W peak pulse rating, −55°C to +175°C operating range, and glass-passivated junction support deployment in engine control units, body electronics, and infotainment power rails where SMA6J13A is specified.
What is the leakage current specification for the SMA6J13A at its working voltage?
The SMA6J13A exhibits a maximum reverse leakage current (IR) of 1.0 µA when biased at its working standoff voltage (VWM) of 13 V and tested at 25°C. This ultra-low leakage ensures minimal power loss in always-on systems and preserves signal integrity in high-impedance sensing paths where SMA6J13A is deployed.
What package type does the SMA6J13A use, and is it compatible with automated assembly?
The SMA6J13A uses the DO-214AC (SMA) surface-mount package, featuring matte tin-plated leads compliant with J-STD-002 solderability standards. Its low-profile geometry and standardized footprint enable reliable high-speed placement and reflow soldering-making SMA6J13A fully compatible with modern automated manufacturing lines.
