Product details
Overview
SMA6J10A from Taiwan Semiconductor is a 600W surface-mount transient voltage suppressor (TVS) diode with 10V working standoff voltage, 11.1–12.3V breakdown voltage at 1mA, 38.2V clamping voltage at 5.0A peak pulse current, and DO-214AC (SMA) package - used for overvoltage protection in DC/DC converters and automotive power supplies.
For engineers reviewing the SMA6J10A datasheet, SMA6J10A pinout, SMA6J10A application, or SMA6J10A equivalent, key selection criteria include clamping performance under 10/1000μs surge, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, junction temperature range (−55°C to +175°C), and RoHS/halogen-free qualification for industrial and automotive-grade designs.
Technical Context
This unidirectional TVS diode operates as a reverse-biased avalanche clamp, activated when reverse voltage exceeds VBR (11.1–12.3V). It delivers 600W peak pulse power per 10/1000μs waveform and maintains <5.0μA leakage at 10V VWM.
Its glass-passivated junction ensures stable breakdown behavior and fast response (<1.0ps), while the DO-214AC package supports automated placement and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards.
Key Specifications

| VWM | 10 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR @ IT=1mA | 11.1–12.3 V - Verified avalanche breakdown threshold ensuring predictable turn-on |
| VC @ IPPM=5.0A | 38.2 V - Clamped voltage during 10/1000μs surge, limiting downstream stress |
| PPPM | 600 W - Peak pulse power handling capability per standard 10/1000μs waveform |
| TJ Range | −55°C to +175°C - Extended thermal operating envelope for under-hood and industrial environments |
| IR @ VWM | <5.0 μA - Low leakage preserves efficiency in high-impedance bias networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J10CA | Bidirectional configuration; symmetric clamping (±38.2V); same VWM, VBR, PPPM | Required where AC-coupled signals or bidirectional data lines need protection | Select SMA6J10CA only if polarity-agnostic clamping is needed; SMA6J10A is optimal for DC rail protection. |
| SMBJ10A | DO-214AA (SMB) package; 600W rating; identical electrical specs but 2.5mm wider body and 0.1mm taller profile | Used when board space allows larger footprint or higher creepage/clearance is mandated | Choose SMBJ10A only if mechanical constraints permit larger package; SMA6J10A offers tighter layout fit in space-constrained SMPS designs. |
Compared with SMA6J10CA and SMBJ10A, the SMA6J10A provides optimal balance of compact DO-214AC footprint, unidirectional clamping for DC rails, and full ISO 7637-2 compliance - making it preferred for cost-sensitive, high-volume automotive and industrial power supply designs.

FAQ
What is the clamping voltage of SMA6J10A at its rated peak pulse current?
The SMA6J10A exhibits a maximum clamping voltage (VC) of 38.2 V when subjected to a 5.0 A peak pulse current under the standard 10/1000μs waveform. This value is measured and guaranteed per the datasheet's electrical specifications table and defines the upper voltage limit imposed on protected circuitry during surge events.
Is SMA6J10A compliant with automotive transient immunity standards?
Yes, SMA6J10A meets ISO 7637-2 requirements for Pulse 1, 2a, 2b, 3a, and 3b waveforms - covering critical automotive transients including load dump, alternator ripple, and inductive switch-off. Its 600W peak pulse rating and 175°C junction temperature support direct integration into automotive power modules.
What is the moisture sensitivity level (MSL) of SMA6J10A, and does it require baking before reflow?
SMA6J10A is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and no baking is required prior to solder reflow. This simplifies manufacturing logistics and eliminates moisture-related popcorning risks during standard lead-free reflow profiles.
How does SMA6J10A differ from SMA6J10CA?
SMA6J10A is unidirectional, protecting only against negative transients on a positive rail, whereas SMA6J10CA is bidirectional with symmetrical ±38.2V clamping. Both share identical VWM, VBR, and PPPM, but SMA6J10A is selected for DC power rail protection, while SMA6J10CA suits AC or dual-polarity signal lines.
What is the maximum steady-state power dissipation (PD) of SMA6J10A at 25°C ambient?
The SMA6J10A has a maximum steady-state power dissipation (PD) of 4 W at TA = 25°C. This rating applies to continuous DC or low-frequency reverse-bias conditions - not surge events - and must be thermally managed via PCB copper area and ambient airflow to maintain TJ ≤175°C.
