Product details
Overview
SMA5J13A-E3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) 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 voltage (VBR at 1 mA), 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 - used to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SMA5J13A-E3/5A datasheet, SMA5J13A-E3/5A pinout, SMA5J13A-E3/5A application, or SMA5J13A-E3/5A equivalent, key selection criteria include clamping performance under 23.3 A surge, thermal resistance (RθJA = 80 °C/W), unidirectional polarity marking, 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 voltage-clamped crowbar device during transients, leveraging a glass-passivated silicon junction for low leakage (<1.0 µA at 13 V) and fast response (<1 ns). Its unidirectional configuration provides forward conduction capability (IFSM = 40 A, 8.3 ms half-sine) while maintaining reverse-biased standoff until VBR is exceeded.
The SMA5J13A-E3/5A is rated for continuous operation from −55 °C to +150 °C junction temperature, with MSL Level 1 moisture sensitivity and J-STD-002/JESD 22-B102 solderability compliance. It meets ANSI/IEEE C62.35 surge standards and is qualified to AEC-Q101 when ordered with HE3/HM3 suffixes - though SMA5J13A-E3/5A itself is commercial-grade RoHS-compliant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before significant leakage; sets safe margin below system rail. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - precise breakdown threshold defining turn-on onset for transient suppression. |
| VC @ IPPM | 21.5 V at 23.3 A - clamped voltage during 500 W surge; determines protected circuit's maximum overvoltage stress. |
| PPPM | 500 W - peak pulse power handling with 10/1000 µs waveform; defines single-event energy absorption capacity. |
| IFSM | 40 A - non-repetitive forward surge current rating (8.3 ms half-sine); supports inrush or fault-current tolerance. |
| RθJA | 80 °C/W - junction-to-ambient thermal resistance; informs PCB copper pad sizing (0.2" × 0.2") for thermal derating. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads. Cathode indicated by band; polarity critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Use Value: Withstands 40 A forward surge (8.3 ms) and clamps to 21.5 V, ensuring MOSFET VDS remains within SOA limits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J13A-M3/5A | Halogen-free, RoHS-compliant variant; identical electrical specs and package; same thermal and surge ratings. | No functional difference; selected where halogen-free materials are mandated (e.g., EU public infrastructure projects). | Direct material substitution when halogen-free compliance is required; no layout or qualification change needed. |
| SMCJ13A-E3/57T | Same VWM/VC ratings but in larger SMC (DO-214AB) package; higher IPPM (33.3 A) and PPPM (1500 W); RθJA = 35 °C/W. | Used where higher surge energy (e.g., ISO 7637-2 Pulse 5a) or improved thermal dissipation is required. | Choose when 500 W is insufficient; requires PCB footprint change and thermal pad redesign due to larger case size. |
Compared with SMA5J13A-E3/5A, the M3/5A variant offers identical protection performance with halogen-free construction, while the SMCJ13A-E3/57T delivers triple the surge power in a larger package - enabling robustness upgrades without changing circuit topology, only layout.

FAQ
What is the clamping voltage of the SMA5J13A-E3/5A under maximum surge conditions?
The SMA5J13A-E3/5A clamps to 21.5 V at its rated peak pulse current of 23.3 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 and represents the maximum voltage imposed on the protected circuit during a standardized surge event. The SMA5J13A-E3/5A maintains this clamping performance across its operational temperature range when mounted on the recommended 5.0 mm × 5.0 mm copper pads.
Is the SMA5J13A-E3/5A suitable for automotive applications?
The SMA5J13A-E3/5A is RoHS-compliant and manufactured to commercial-grade specifications. While it shares the same die and package as AEC-Q101-qualified variants (e.g., SMA5J13AHE3_A), the SMA5J13A-E3/5A itself is not AEC-Q101 certified. For production automotive use, engineers should specify the HE3 or HM3 suffix versions; the SMA5J13A-E3/5A is appropriate for prototyping, non-safety-critical subsystems, or industrial applications with similar surge profiles.
What does the "E3/5A" suffix indicate in SMA5J13A-E3/5A?
The "E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability requirements. The "5A" specifies the packaging format: 7500 units per 13-inch diameter plastic tape and reel. This differs from "61", which indicates 1800 units per 7-inch reel. Both formats use the same device die and electrical characteristics.
How does the SMA5J13A-E3/5A compare to SMAJ13A in terms of surge capability?
The SMA5J13A-E3/5A delivers 500 W peak pulse power (10/1000 µs), whereas the SMAJ13A is rated for 400 W. This 25 % higher power rating allows the SMA5J13A-E3/5A to handle larger transient energies without degradation. Both share the same SMA (DO-214AC) package, VWM = 13 V, and VC = 21.5 V, but the SMA5J13A-E3/5A achieves higher IPPM (23.3 A vs. 18.7 A) due to optimized chip design and thermal path.
Can the SMA5J13A-E3/5A be used in bidirectional configurations?
No - the SMA5J13A-E3/5A is strictly unidirectional, as confirmed by its part number (no "CA" suffix) and polarity marking (cathode band). Bidirectional operation requires the CA-suffixed variant (e.g., SMA5J13CA), which has symmetrical breakdown in both directions and no polarity marking. Using SMA5J13A-E3/5A in reverse-biased AC applications risks permanent failure due to forward conduction during negative half-cycles.
