Product details
Overview
SMA6J13A-E3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode 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 (VC at IPP = 29.4 A, 10/1000 µs), 600 W peak pulse power rating, and 50 A peak forward surge current. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and telecom equipment.
For engineers reviewing the SMA6J13A-E3/61 datasheet, SMA6J13A-E3/61 pinout, SMA6J13A-E3/61 application, or SMA6J13A-E3/61 equivalent, key selection criteria include clamping voltage margin relative to protected device's absolute maximum rating, unidirectional polarity compatibility with DC-biased lines, thermal resistance (RθJA = 120 °C/W), and RoHS-compliant matte tin-plated leads suitable for J-STD-002 soldering.
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 VBR (14.4–15.9 V), it avalanches rapidly to clamp the line at ≤20.4 V (at 29.4 A, 10/1000 µs). Its dynamic resistance (RD = 0.153 Ω) ensures low-voltage overshoot during fast transients.
Designed for PCB-level protection of DC power rails and low-speed signal paths, it complies with MSL level 1 per J-STD-020, supports 260 °C reflow peak temperature, and uses UL 94 V-0 molding compound. The cathode band denotes polarity, and its DO-214AC footprint enables automated placement on 5.0 mm × 5.0 mm copper pads per terminal for optimal thermal dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected circuit's steady-state DC rail. |
| VBR (min/max) | 14.4 V / 15.9 V at IT = 1 mA - Breakdown onset range; defines minimum overvoltage threshold triggering clamping action. |
| VC @ IPP | 20.4 V at 29.4 A (10/1000 µs) - Clamped voltage during standardized surge; must remain below protected device's absolute max rating. |
| PPPM (10×1000 µs) | 600 W - Peak transient energy handling capability; determines survivability of common inductive-switching events. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance; used with PD = 4 W at TA = 50 °C to estimate junction temperature rise. |
| Polarity | Unidirectional - Blocks reverse current only; requires correct orientation across DC-biased lines like power supplies or I/O with defined ground reference. |
| IFSM | 50 A - Non-repetitive forward surge rating; supports brief inrush or fault currents without degradation. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads, UL 94 V-0 rated molding compound, cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient current sink path | Connected to protected line (e.g., VCC or signal); conducts avalanche current during overvoltage. |
| Cathode | Reference node / return path to ground or lower potential | Connected to system ground or return rail; polarity marking ensures correct installation on DC-biased circuits. |
Key Features
| Feature | Design Value |
|---|---|
| Clamping performance | 20.4 V VC at 29.4 A (10/1000 µs) enables robust protection of 15 V logic and 24 V industrial rails without overstressing downstream ICs. |
| Thermal reliability | RθJA = 120 °C/W and TJ(max) = 150 °C support sustained operation in enclosed industrial enclosures up to +50 °C ambient. |
| Manufacturing compatibility | MSL level 1 rating and 260 °C reflow peak tolerance ensure compatibility with standard SMT assembly processes without baking or special handling. |
| Environmental compliance | E3 suffix indicates RoHS-compliant, industrial-grade construction with JESD 201 class 2 whisker resistance and UL 94 V-0 flammability rating. |
Applications
| Industrial Motor Control | Telecom Power Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J13A-M3/61 | Halogen-free, RoHS-compliant variant with identical electrical specs and same SMA package; differs only in material composition (no brominated flame retardants). | Required where halogen-free compliance is mandated by end-equipment environmental standards (e.g., EU WEEE, certain automotive OEM specs). | Select SMA6J13A-M3/61 when halogen-free materials are contractually required; otherwise SMA6J13A-E3/61 satisfies general industrial RoHS needs. |
| SMCJ13A-E3/73 | Same VWM (13 V) and VBR range but in larger SMC (DO-214AB) package; higher PPPM (1500 W, 10/1000 µs) and lower RθJA (60 °C/W), yet same clamping voltage (20.4 V). | Better suited for high-energy surge environments (e.g., outdoor telecom cabinets) where board space allows larger footprint and thermal mass improves long-duration surge handling. | Choose SMCJ13A-E3/73 when surge energy exceeds 600 W or ambient temperatures exceed 50 °C; SMA6J13A-E3/61 remains optimal for space-constrained, cost-sensitive designs. |
Compared with SMA6J13A-M3/61, the SMA6J13A-E3/61 offers identical protection performance with standard RoHS compliance; versus SMCJ13A-E3/73, it trades higher surge capacity and thermal margin for smaller size and lower cost-making SMA6J13A-E3/61 ideal for compact industrial and consumer PCBs where 600 W surge immunity suffices.

FAQ
What is the maximum clamping voltage of the SMA6J13A-E3/61 under a 10/1000 µs surge?
The SMA6J13A-E3/61 has a maximum clamping voltage (VC) of 20.4 V when subjected to a 29.4 A peak pulse current with a 10/1000 µs waveform. This value is measured per the conditions specified in the Vishay datasheet (Document Number: 89460) and reflects the device's ability to limit transient voltage across protected circuitry while conducting surge current. The SMA6J13A-E3/61 maintains this clamping performance within its specified operating temperature range.
Does the SMA6J13A-E3/61 support bidirectional transient suppression?
No, the SMA6J13A-E3/61 is a unidirectional TVS diode and provides transient suppression only in the reverse-bias direction. It is not designed to clamp positive-going transients on AC-coupled or bipolar signal lines. For bidirectional protection, a separate device such as the SMBJ13CA or a dual-diode configuration would be required. The SMA6J13A-E3/61's polarity is marked by a cathode band and must be oriented with cathode toward the higher-potential side of a DC rail.
What is the thermal resistance and power derating behavior of the SMA6J13A-E3/61?
The SMA6J13A-E3/61 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. Its power dissipation (PD) is rated at 4.0 W at TA = 50 °C and derates linearly above that temperature, reaching zero at TJ = 150 °C. This derating curve is documented in Figure 2 of the Vishay datasheet (89460) and must be applied in thermal design to ensure junction temperature remains within safe limits during continuous operation.
Is the SMA6J13A-E3/61 compatible with lead-free reflow soldering processes?
Yes, the SMA6J13A-E3/61 is qualified for lead-free reflow soldering with a maximum peak temperature of 260 °C, meeting J-STD-020 moisture sensitivity level (MSL) 1 requirements. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, and the E3 suffix confirms RoHS compliance. No pre-baking is required prior to assembly, simplifying manufacturing flow for high-volume SMT lines.
How does the leakage current of the SMA6J13A-E3/61 compare at its stand-off voltage?
At its 13 V stand-off voltage (VWM), the SMA6J13A-E3/61 exhibits a maximum reverse leakage current (ID) of 1 µA at TA = 25 °C, rising to ≤1 µA at 85 °C per the datasheet. This ultra-low leakage ensures minimal loading on sensitive 13 V power rails or high-impedance sensor interfaces, preserving system efficiency and signal integrity without introducing measurable error or drift in precision analog circuits using the SMA6J13A-E3/61.
