Product details
Overview
SMA5J13-E3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on power and signal lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown range (VBR), 21.5 V clamping voltage (VC) at 23.3 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMA5J13-E3/5A datasheet, SMA5J13-E3/5A pinout, SMA5J13-E3/5A application, or SMA5J13-E3/5A equivalent, this device is selected for robust overvoltage protection in automotive power rails, industrial sensor interfaces, and DC input stages where fast response (<1 ns), low clamping ratio, and AEC-Q101 qualification are required.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging an avalanche breakdown mechanism to limit transient voltages before they damage downstream ICs or MOSFETs. Its glass-passivated junction ensures stable leakage performance and long-term reliability under repeated surge stress.
The SMA5J13-E3/5A is rated for -55 °C to +150 °C operating junction temperature, exhibits 1.0 µA maximum reverse leakage at VWM, and maintains low incremental surge resistance to minimize voltage overshoot during 8.3 ms half-sine surges up to 40 A (IFSM).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J13AHE3/5A | AEC-Q101 qualified variant with identical electrical specs; differs only in whisker test class (Class 2 vs. Class 1A) | Required for automotive safety-critical modules where enhanced whisker resistance is mandated | Select SMA5J13AHE3/5A when full AEC-Q101 compliance documentation and JESD201 Class 2 testing are contractually required |
| SMC5J13A-E3/57T | Same VWM/VC but in larger DO-214AB (SMC) package; higher thermal mass supports longer surge duration | Better suited for repetitive surge environments (e.g., motor control feedback loops) due to lower RθJA (50 °C/W vs. 80 °C/W) | Choose SMC5J13A-E3/57T when thermal cycling or >100 surges/hour is expected; requires PCB layout change |
Compared with SMA5J13-E3/5A, the HE3 variant adds whisker test assurance without electrical trade-offs, while the SMC5J13A offers superior thermal endurance at the cost of footprint size-enabling design flexibility for either automotive qualification rigor or high-duty-cycle industrial use.

FAQ
What is the clamping voltage of the SMA5J13-E3/5A under a 500 W transient?
The SMA5J13-E3/5A clamps to a maximum of 21.5 V when subjected to its rated 500 W peak pulse power with a 10/1000 µs waveform. This value is measured at the specified peak pulse current of 23.3 A and defines the upper voltage limit imposed on protected circuitry during surge events. The SMA5J13-E3/5A achieves this clamping performance while maintaining low incremental resistance, ensuring minimal overshoot beyond the rated VC.
Is the SMA5J13-E3/5A suitable for automotive applications?
Yes, the SMA5J13-E3/5A is AEC-Q101 qualified and designed for automotive use, including engine control units, body electronics, and infotainment power supplies. Its -55 °C to +150 °C operating temperature range, glass-passivated junction, and MSL Level 1 reflow compatibility meet stringent automotive manufacturing and field reliability requirements. The SMA5J13-E3/5A also complies with RoHS and halogen-free standards per JEDEC JS709A.
How does the SMA5J13-E3/5A differ from bi-directional variants like SMA5J13CA?
The SMA5J13-E3/5A is unidirectional and features a cathode band marking; it conducts only in reverse breakdown and blocks forward current up to 3.5 V at 25 A. In contrast, SMA5J13CA is bi-directional with no polarity marking and clamps symmetrically in both directions. The SMA5J13-E3/5A provides lower leakage and tighter VBR tolerance for DC-biased lines, whereas SMA5J13CA suits AC-coupled or floating signal paths.
What is the maximum reverse leakage current for the SMA5J13-E3/5A at its stand-off voltage?
The SMA5J13-E3/5A exhibits a maximum reverse leakage current of 1.0 µA at its 13 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage preserves system efficiency in battery-powered or always-on applications and ensures minimal loading on sensitive analog or reference circuits. The SMA5J13-E3/5A maintains this specification across its full operating temperature range per datasheet characterization.
Can the SMA5J13-E3/5A be used in place of SMA5J13A?
Yes, SMA5J13-E3/5A is functionally identical to SMA5J13A in electrical and thermal specifications; the "E3/5A" suffix denotes RoHS-compliant packaging in 13-inch tape-and-reel format (7500 units), while "SMA5J13A" typically refers to the base part number without packaging detail. Both share the same DO-214AC (SMA) package, VWM, VBR, VC, and AEC-Q101 qualification. The SMA5J13-E3/5A is the orderable commercial-grade version supplied by Vishay.
