Product details
Overview
SMA6J13A-M3/61 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR at IT = 1 mA), 20.4 V max clamping voltage at 29.4 A (10/1000 µs), 600 W peak pulse power, and operates from –55 °C to +150 °C - used to protect MOSFETs and sensor signal lines in industrial motor drives.
For engineers reviewing the SMA6J13A-M3/61 datasheet, SMA6J13A-M3/61 pinout, SMA6J13A-M3/61 application, or SMA6J13A-M3/61 equivalent, key selection criteria include unidirectional polarity, 20.4 V clamping at 29.4 A surge, SMA package thermal resistance (RθJA = 120 °C/W), 0.2 µA leakage at 13 V, and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker test.
Technical Context
This TVS diode uses an avalanche breakdown mechanism to clamp fast-rising transients with sub-nanosecond response time. Its dynamic resistance (RD = 0.153 Ω) enables low-voltage overshoot during high-current surges up to 29.4 A (10/1000 µs) or 147 A (8/20 µs).
Designed for PCB mounting on 5.0 mm × 5.0 mm copper pads per terminal, it achieves 4 W power dissipation at TA = 50 °C and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility. The cathode band denotes polarity, and matte tin-plated leads ensure solderability per J-STD-002 and JESD22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before leakage exceeds 0.2 µA |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - ensures reliable avalanche initiation within defined tolerance band |
| VC @ IPP | 20.4 V at 29.4 A (10/1000 µs) - limits downstream IC voltage stress during common surge events |
| PPPM (10/1000 µs) | 600 W - defines energy-handling capability for lightning-induced or inductive-switching transients |
| IFSM | 50 A - withstands single half-sine 8.3 ms surge without degradation, critical for input-stage protection |
| TJ max. | +150 °C - supports operation in enclosed industrial enclosures with limited airflow |
| RθJA | 120 °C/W - determines required PCB copper area for thermal management at 4 W dissipation |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads; cathode indicated by color band; compliant with UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry under forward bias; reference node for clamping action | Connected to protected line (e.g., VIN or signal trace); forms clamping path to ground via cathode |
| Cathode | Current exit under forward bias; clamping reference point | Typically tied to system ground or low-impedance return; voltage rise above ground triggers avalanche conduction |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional polarity | Enables precise clamping only on negative-going transients relative to cathode, avoiding interference with DC bias |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets JESD201 Class 2 whisker resistance and environmental compliance for automotive/industrial deployments |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard 260 °C Pb-free reflow without baking preconditioning |
| Low dynamic resistance (0.153 Ω) | Minimizes clamping voltage overshoot during high di/dt events, improving protection margin for 3.3 V/5 V logic |
| 120 °C/W junction-to-ambient thermal resistance | Defines minimum 5.0 mm × 5.0 mm copper pad area per terminal to sustain 4 W at TA = 50 °C |
Applications
| Industrial Motor Drive Protection | Automotive Sensor Signal Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J13A-E3/61 | Same electrical specs; RoHS-compliant but not halogen-free; uses SnPb-compatible plating (E3 suffix) | Preferred for legacy Pb-containing assembly lines; lacks JESD201 Class 2 whisker qualification | Select SMA6J13A-E3/61 only when halogen-free requirement is waived and SnPb process is used. |
| SMAJ13A-M3 | Lower 400 W PPPM (10/1000 µs); identical VWM/VBR/VC; same SMA package and M3 suffix | Suitable for lower-energy transients (e.g., ESD-only); insufficient for 600 W inductive switching events | Choose SMAJ13A-M3 only if system-level testing confirms 400 W surge immunity is sufficient. |
Compared with SMA6J13A-M3/61, SMA6J13A-E3/61 offers identical surge performance but lacks halogen-free certification, while SMAJ13A-M3 reduces peak power handling by 33 % - requiring design validation for energy-limited applications.

FAQ
What is the clamping voltage of SMA6J13A-M3/61 at its rated peak pulse current?
The SMA6J13A-M3/61 has a maximum clamping voltage (VC) of 20.4 V at 29.4 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during surge events. The SMA6J13A-M3/61 maintains this clamping performance across its full operating temperature range from –55 °C to +150 °C.
Does SMA6J13A-M3/61 support lead-free reflow soldering?
Yes, SMA6J13A-M3/61 meets J-STD-020 MSL Level 1 and is qualified for lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102 solderability requirements. The SMA6J13A-M3/61 also passes JESD201 Class 2 whisker testing, confirming long-term reliability under thermal cycling in halogen-free assemblies.
How does the M3 suffix differ from E3 in SMA6J13A-M3/61?
The M3 suffix indicates halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance, whereas E3 denotes RoHS compliance without halogen-free assurance. Both share identical electrical parameters and SMA (DO-214AC) packaging. For designs requiring full environmental compliance per IPC-1752A or automotive OEM specifications, SMA6J13A-M3/61 is mandatory - the SMA6J13A-M3/61 replaces E3 where halogen content restrictions apply.
What is the thermal resistance of SMA6J13A-M3/61, and how does it affect layout?
SMA6J13A-M3/61 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. This value directly determines PCB copper area requirements: reducing pad size increases thermal resistance, risking junction overheating above the 150 °C maximum. The SMA6J13A-M3/61 must be placed with unobstructed thermal vias beneath pads if ambient temperatures exceed 50 °C.
Can SMA6J13A-M3/61 be used for bidirectional transient suppression?
No, SMA6J13A-M3/61 is unidirectional only, as confirmed in the Vishay datasheet under FEATURES and ELECTRICAL CHARACTERISTICS. It conducts only when cathode voltage exceeds anode voltage by ≥14.4 V - making it unsuitable for AC lines or bidirectional data buses. For bidirectional protection, a pair of SMA6J13A-M3/61 devices in series opposition or a dedicated bidirectional TVS such as SMBJ13A-M3 would be required instead of the SMA6J13A-M3/61.
