Product details
Overview
SMA5J10A-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 17.0 V clamping voltage at 29.4 A peak pulse current (IPPM), and 500 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the SMA5J10A-E3/61 datasheet, SMA5J10A-E3/61 pinout, SMA5J10A-E3/61 application, or SMA5J10A-E3/61 equivalent, key selection criteria include clamping performance under 29.4 A surge, thermal resistance (RθJA = 80 °C/W), RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable breakdown and low incremental surge resistance. Its response time is sub-nanosecond, enabling effective suppression of fast transients induced by inductive switching or ESD events.
Rated for -55 °C to +150 °C junction temperature range and qualified per J-STD-020 MSL Level 1 (260 °C peak reflow), the SMA5J10A-E3/61 is optimized for surface-mount reliability in automotive, industrial, and telecom power rail protection where high power density and repeatable clamping are critical.
Key Specifications

|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VBR (min/max) | 11.1 V / 12.3 V - Measured at 1 mA test current; ensures predictable turn-on threshold across production lot. |
| VC @ IPPM | 17.0 V at 29.4 A - Clamping voltage under 10/1000 μs surge; determines protected circuit's maximum transient exposure. |
| PPPM | 500 W - Peak pulse power handling capability; supports single-event surge immunity per IEC 61000-4-5. |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance on standard 5.0 mm × 5.0 mm pads; informs derating above 25 °C ambient. |
| IFSM | 40 A - Non-repetitive forward surge rating (8.3 ms half-sine); validates robustness against accidental polarity reversal. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/61 | Lower PPPM (400 W vs. 500 W); same VWM/VBR/VC but reduced IPPM (24.7 A vs. 29.4 A). | Suitable for less severe surge environments (e.g., consumer USB ports), not recommended for automotive load dump. | Select SMA5J10A-E3/61 when 500 W surge headroom and 29.4 A clamping current are required. |
| SMBJ10A-E3/52 | Same electrical specs but SMB (DO-214AA) package - 2.54 mm lead pitch vs. SMA's 2.29 mm; 10% larger footprint. | Acceptable where board space permits; higher RθJA (~70 °C/W) requires larger copper area for thermal management. | Choose SMA5J10A-E3/61 for tighter layout constraints and superior power density in space-constrained designs. |
Compared with SMAJ10A-E3/61 and SMBJ10A-E3/52, the SMA5J10A-E3/61 delivers 25% higher surge power handling in the smallest DO-214 footprint, making it optimal for automotive and industrial applications demanding both compact size and robust 500 W transient immunity.

FAQ
What is the clamping voltage of the SMA5J10A-E3/61 under maximum rated surge current?
The SMA5J10A-E3/61 exhibits a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current (IPPM) of 29.4 A using the standardized 10/1000 μs waveform. This value is measured at room temperature with the device mounted on 5.0 mm × 5.0 mm copper pads per JEDEC guidelines, ensuring repeatable performance in production assemblies.
Is the SMA5J10A-E3/61 suitable for automotive applications?
Yes - while the base SMA5J10A-E3/61 is commercial-grade RoHS-compliant, Vishay offers AEC-Q101-qualified variants (e.g., SMA5J10AHE3_A) with identical electrical specs. The SMA5J10A-E3/61 itself shares the same construction, thermal performance (TJ max = 150 °C), and surge robustness required for under-hood and infotainment use, pending customer qualification.
What does the "E3/61" suffix indicate in SMA5J10A-E3/61?
The "E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. The "/61" specifies packaging in 7-inch plastic tape and reel with 1800 units per reel - the preferred logistics format for high-volume SMT manufacturing lines.
How does the SMA5J10A-E3/61 compare to bidirectional TVS diodes like SMA5J10CA?
The SMA5J10A-E3/61 is unidirectional and intended for DC rail protection with defined polarity (cathode band). In contrast, SMA5J10CA provides symmetrical clamping for AC or floating signal lines. Their VWM, VBR, and VC values differ: SMA5J10CA has VWM = 10 V but bidirectional VBR = 11.1–12.3 V in both directions, whereas SMA5J10A-E3/61 only clamps in reverse bias.
What is the maximum operating temperature for the SMA5J10A-E3/61?
The SMA5J10A-E3/61 has a specified junction and storage temperature range of -55 °C to +150 °C. Its thermal resistance (RθJA = 80 °C/W) allows operation up to +125 °C ambient when derated per Figure 2 in the datasheet, provided PCB copper area meets the 5.0 mm × 5.0 mm pad recommendation for thermal dissipation.
