Product details
Overview
SMA6J13A-E3/5A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in SMA (DO-214AC) package, with 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR at IT = 1 mA), 20.4 V maximum clamping voltage at 29.4 A (10/1000 μs), 600 W peak pulse power rating, and 150 °C maximum junction temperature. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the SMA6J13A-E3/5A datasheet, SMA6J13A-E3/5A pinout, SMA6J13A-E3/5A application, or SMA6J13A-E3/5A equivalent, key selection criteria include clamping voltage margin vs. protected device VDS(max), unidirectional polarity compatibility with DC-biased lines, thermal resistance (RθJA = 120 °C/W), and RoHS-compliant matte tin plating for J-STD-002 solderability.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias (≤13 V), it presents <1 μA leakage; during transient overvoltage exceeding 14.4 V, it avalanches to clamp the line at ≤20.4 V while diverting up to 29.4 A (10/1000 μs) or 147 A (8/20 μs). Its dynamic resistance (RD = 0.153 Ω) ensures low-voltage overshoot during fast surges.
Designed for PCB-mounted protection on signal or power rails, it uses a planar junction structure in an SMA package rated MSL Level 1 (260 °C reflow peak), with cathode indicated by a color band and terminals optimized for automated placement on 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; sets upper limit for protected circuit DC bias. |
| VBR min/max | 14.4 V / 15.9 V at 1 mA - Confirmed avalanche onset range; defines minimum overvoltage threshold for clamping activation. |
| VC @ IPP | 20.4 V at 29.4 A (10/1000 μs) - Measured clamping voltage under standard surge; must be below protected device's absolute maximum rating. |
| PPPM (10×1000 μs) | 600 W - Peak surge energy handling capacity; determines survivability of common inductive load-switching transients. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance on standard PCB pad layout; used to calculate ΔTJ rise under sustained power dissipation. |
| Polarity | Unidirectional - Only conducts in reverse breakdown; requires correct orientation relative to DC rail polarity. |
| IFSM | 50 A - Non-repetitive forward surge current rating; relevant for accidental forward-bias fault conditions. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102; cathode denoted by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference node | Connected to lower-potential side of protected line; establishes reference for unidirectional clamping action. |
| Cathode | Avalanche conduction terminal / Clamping output | Connected to higher-potential side (e.g., VCC rail); sinks surge current into ground or return path during overvoltage event. |
Key Features
| Feature | Design Value |
|---|---|
| Clamping performance | 20.4 V max clamping at 29.4 A (10/1000 μs) enables robust protection of 20 V-rated MOSFETs with ≥2 V safety margin. |
| Thermal reliability | RθJA = 120 °C/W and TJ(max) = 150 °C allow stable operation at PD = 4 W (TA = 50 °C) without forced cooling. |
| Manufacturing compatibility | MSL Level 1 rating and 260 °C peak reflow tolerance support standard SMT assembly without prebaking. |
| Material compliance | E3 suffix indicates RoHS-compliant, industrial-grade construction with UL 94 V-0 molding compound. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J13CA-E3/5A | Bidirectional variant; symmetrical ±13 V stand-off; identical VBR, VC, and PPPM ratings. | Required where protected line may experience reversible polarity transients (e.g., differential data lines, AC-coupled sensors). | Select SMA6J13CA-E3/5A only if bidirectional clamping is mandated; SMA6J13A-E3/5A offers lower capacitance and tighter leakage in DC-biased applications. |
| SMCJ13A-E3/57T | Higher-power SMC (DO-214AB) package; same VWM/VBR but 1500 W (10/1000 μs) PPPM and RθJA = 35 °C/W. | Suitable for high-energy surge environments (e.g., outdoor power systems) where 600 W is insufficient. | Choose SMCJ13A-E3/57T when board space allows larger package and thermal design requires lower junction rise per watt. |
Compared with SMA6J13CA-E3/5A, the SMA6J13A-E3/5A provides superior leakage control (<1 μA) for DC rails, while versus SMCJ13A-E3/57T, it trades power handling for compactness and cost-ideal for space-constrained consumer and industrial PCBs where 600 W meets IEC 61000-4-4 immunity requirements.

FAQ
What is the maximum clamping voltage of the SMA6J13A-E3/5A under a 10/1000 μs surge?
The SMA6J13A-E3/5A has a maximum clamping voltage (VC) of 20.4 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 29.4 A. This value is measured per the test conditions specified in the Vishay datasheet (Document Number: 89460) and reflects worst-case clamping performance at TA = 25 °C with recommended PCB pad layout.
Is the SMA6J13A-E3/5A suitable for protecting 12 V automotive circuits?
Yes, the SMA6J13A-E3/5A is suitable for 12 V automotive circuits such as body control modules, provided the protected line is DC-biased and unidirectional. Its 13 V stand-off voltage (VWM) accommodates nominal 12 V systems with margin for ripple and tolerance, and its 20.4 V clamping voltage stays safely below typical 24 V-rated automotive ICs and MOSFETs.
Does the SMA6J13A-E3/5A have a bidirectional variant?
Yes, the bidirectional variant is the SMA6J13CA-E3/5A, which features symmetrical ±13 V stand-off voltage and identical breakdown, clamping, and power ratings. The 'C' in the part number denotes bidirectional configuration, whereas the 'A' in SMA6J13A-E3/5A confirms unidirectional polarity.
What is the thermal resistance of the SMA6J13A-E3/5A, and how does it affect PCB layout?
The SMA6J13A-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. To maintain safe junction temperature under sustained power dissipation, PCB layout must provide adequate copper area and avoid thermal bottlenecks-reducing pad size increases RθJA and risks thermal runaway at elevated ambient temperatures.
What does the 'E3/5A' suffix mean in SMA6J13A-E3/5A?
The 'E3' suffix indicates RoHS-compliant, industrial-grade construction with matte tin-plated leads and UL 94 V-0 molding compound. The '/5A' denotes packaging in 13-inch diameter plastic tape and reel containing 7500 units, optimized for high-volume SMT placement equipment.
