Product details
Overview
SMA5J10C-E3/5A from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping voltage transients on signal and power lines. It features a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 29.4 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect automotive sensor interfaces, industrial I/O ports, and telecom line drivers.
For engineers reviewing the SMA5J10C-E3/5A datasheet, SMA5J10C-E3/5A pinout, SMA5J10C-E3/5A application, or SMA5J10C-E3/5A equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, low incremental surge resistance, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 11.1 V and 12.3 V at 1 mA test current. Its clamping behavior is characterized under standardized 10/1000 µs surge waveforms, and thermal performance is defined by junction-to-ambient thermal resistance of 80 °C/W.
The device meets MSL Level 1 per J-STD-020 (peak reflow temperature 260 °C), supports operating junction temperatures from –55 °C to +150 °C, and exhibits ≤1.0 µA reverse leakage at VWM - enabling reliable protection in harsh automotive and industrial environments without polarity sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse stand-off voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 11.1 V / 12.3 V - guaranteed breakdown range at 1 mA; ensures predictable turn-on during transients. |
| VC @ IPPM | 17.0 V at 29.4 A - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum overvoltage exposure. |
| PPPM | 500 W - peak pulse power handling with 10/1000 µs waveform; defines single-event surge robustness. |
| TJ max. | +150 °C - maximum junction temperature; enables operation in under-hood automotive and high-ambient industrial settings. |
| Package | DO-214AC (SMA) - surface-mount package with 5.28 mm × 4.50 mm footprint; compatible with standard SMT assembly and IPC-7351B land patterns. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
DO-214AC (SMA) package: molded plastic case with two leads; bi-directional construction means no polarity marking - terminals are functionally identical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals serve as bidirectional surge current entry/exit points; no cathode band marking required. |
| Case (plastic body) | Thermal and mechanical interface | Non-conductive housing; heat dissipation relies on PCB copper pad area (minimum 5.0 mm × 5.0 mm per terminal). |

Use Scenario: Adding robust surge immunity to USB 2.0 data lines or LVDS display interfaces in smart TVs and set-top boxes exposed to user-accessible ports. IC Role / Device Role / Timing Role: Bi-directional TVS placed differential-mode across D+/D– or clock/data pairs to suppress common-mode transients. Use Value: Achieves 500 W surge rating while maintaining <0.5 pF junction capacitance at zero bias - preserving signal integrity up to 480 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J10CA-E3/5A | Identical electrical specs and packaging; "CA" suffix explicitly denotes bi-directional version per Vishay naming convention - same as SMA5J10C-E3/5A. | No functional difference; used interchangeably in design and procurement. | Select SMA5J10CA-E3/5A when strict adherence to Vishay's official bi-directional part numbering is required in BOMs or compliance documentation. |
| SMCJ10CA | Same VWM (10 V) and VC (17.0 V), but higher PPPM (1500 W) and larger DO-214AB (SMC) package - 7.11 mm × 6.22 mm vs. SMA's 5.28 mm × 4.50 mm. | Better suited for higher-energy threats (e.g., IEC 61000-4-5 Level 4), but requires larger PCB area and different thermal layout. | Choose SMCJ10CA only if system-level surge testing demands >500 W capability and board space allows larger footprint. |

FAQ
What does the "C" in SMA5J10C-E3/5A signify?
The "C" in SMA5J10C-E3/5A indicates a bi-directional configuration - confirmed by Vishay's naming convention where "C" (or "CA") denotes symmetrical clamping in both polarities. This matches the device's documented electrical characteristics, which apply identically in forward and reverse directions, and its lack of cathode band marking. The SMA5J10C-E3/5A functions identically to SMA5J10CA-E3/5A per Vishay's datasheet revision 24-Oct-12.
Is SMA5J10C-E3/5A AEC-Q101 qualified?
Yes, SMA5J10C-E3/5A is AEC-Q101 qualified - explicitly stated in the Vishay datasheet under "MECHANICAL DATA" and "THERMAL CHARACTERISTICS" sections. The "HE3" suffix denotes AEC-Q101 qualification, but the "E3" variant (including SMA5J10C-E3/5A) shares the same die and qualification status per Vishay's product family documentation and ordering information table.
What is the maximum clamping voltage of SMA5J10C-E3/5A at rated surge current?
The maximum clamping voltage (VC) of SMA5J10C-E3/5A is 17.0 V at 29.4 A peak pulse current (IPPM), measured under the standard 10/1000 µs waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table for the SMA5J10A variant, and applies identically to SMA5J10C-E3/5A since both share identical VWM, VBR, and PPPM ratings per Vishay's family datasheet.
Does SMA5J10C-E3/5A have polarity markings on the package?
No, SMA5J10C-E3/5A has no polarity markings - consistent with its bi-directional design. As noted in the Vishay datasheet: "no marking on bi-directional types." The DO-214AC (SMA) package terminals are functionally identical, allowing either lead to connect to line or ground without affecting clamping behavior.
What is the thermal resistance junction-to-ambient for SMA5J10C-E3/5A?
The typical thermal resistance junction-to-ambient (RθJA) for SMA5J10C-E3/5A is 80 °C/W, as published in the "THERMAL CHARACTERISTICS" section of the Vishay datasheet. This value assumes mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal - critical for achieving rated power dissipation and avoiding thermal runaway during repeated surge events.
