Product details
Overview
SMA6J13A-M3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode 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 maximum clamping voltage at 23.9 A (10/1000 μs), 600 W peak pulse power rating, and operates from –55 °C to +150 °C junction temperature - used to protect MOSFETs and ICs in industrial power supplies.
For engineers reviewing the SMA6J13A-M3/5A datasheet, SMA6J13A-M3/5A pinout, SMA6J13A-M3/5A application, or SMA6J13A-M3/5A equivalent, key selection criteria include unidirectional polarity, 20.4 V clamping performance at 23.9 A surge, SMA package thermal resistance (RθJA = 120 °C/W), 0.2 μA leakage at 13 V, and halogen-free RoHS-compliant construction per M3 suffix.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (< 0.2 μA leakage at VWM = 13 V), then rapidly avalanches when reverse voltage exceeds VBR (14.4–15.9 V), limiting transient energy via low dynamic resistance (RD = 0.153 Ω). Its clamping behavior follows VCL = RD × IPP + VBRmax, enabling predictable overvoltage suppression.
Designed for PCB-level protection against inductive switching spikes and lightning surges, it delivers 600 W (10/1000 μs) and 4000 W (8/20 μs) peak pulse power with derating above TA = 25 °C. The SMA (DO-214AC) package supports automated placement and meets J-STD-020 MSL level 1 (260 °C reflow peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working margin below clamping threshold. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - Breakdown onset range; ensures reliable avalanche initiation without premature conduction. |
| VC at IPP | 20.4 V at 23.9 A (10/1000 μs) - Clamped voltage during standard surge; determines protected circuit's maximum transient exposure. |
| PPPM (10/1000 μs) | 600 W - Peak transient energy absorption capability under standardized long-duration surge waveform. |
| ID at VWM | 0.2 μA - Reverse leakage current at rated stand-off voltage; critical for low-power sensor line integrity. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in high-ambient industrial environments with appropriate PCB copper area. |
| RθJA | 120 °C/W - Thermal resistance junction-to-ambient on standard 5.0 mm × 5.0 mm pads; informs derating requirements for sustained power dissipation. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads, cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to protected line's low-side reference (e.g., ground or return rail); completes clamping loop during surge. |
| Cathode | Transient voltage sensing / clamping node | Connected to the line being protected (e.g., 12 V rail); avalanche conduction begins here when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional polarity | Enables precise clamping only on negative transients relative to cathode; avoids forward conduction interference on DC-biased lines. |
| 600 W (10/1000 μs) PPPM | Provides robust protection against common inductive-switching surges in motor drives and relay circuits without thermal runaway. |
| MSL Level 1 compliance | Supports lead-free reflow up to 260 °C peak without popcorn cracking or delamination - suitable for high-yield SMT assembly. |
| 0.153 Ω dynamic resistance (RD) | Ensures tight clamping voltage control across surge current range; minimizes overshoot beyond VC specification. |
| Halogen-free M3 construction | Meets IEC 61249-2-21 and JEDEC J-STD-207 standards for environmentally constrained applications including automotive and industrial controls. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |

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-E3/5A | Same electrical specs, but RoHS-compliant with lead-free finish (E3 suffix); no halogen-free certification. | Preferred where halogen content is unrestricted but full RoHS compliance is required; identical MSL level and thermal performance. | Select E3 for cost-sensitive industrial designs without halogen restrictions; M3 required for automotive or green-certified systems. |
| SMB6J13A-M3 | Same VWM/VBR/VC ratings, but SMB (DO-214AA) package - 2.5 mm wider body, higher RθJA (100 °C/W), 1000 W PPPM (10/1000 μs). | Better suited for higher-power or lower-thermal-resistance layouts; requires larger PCB footprint than SMA. | Choose SMB6J13A-M3 when surge energy exceeds 600 W or board layout allows larger package; SMA6J13A-M3 preferred for space-constrained designs. |
Compared with SMA6J13A-E3/5A, the M3 variant adds halogen-free compliance without sacrificing clamping performance; versus SMB6J13A-M3, the SMA version trades 400 W lower PPPM for 30 % smaller footprint and compatibility with tighter pitch layouts.

FAQ
What is the clamping voltage of SMA6J13A-M3/5A at its rated peak pulse current?
The SMA6J13A-M3/5A has a maximum clamping voltage (VC) of 20.4 V at 23.9 A peak pulse current under the 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads) and reflects the actual voltage seen by protected circuitry during surge events. The SMA6J13A-M3/5A maintains this clamping performance across its specified operating temperature range.
Does SMA6J13A-M3/5A support lead-free reflow soldering?
Yes, SMA6J13A-M3/5A meets J-STD-020 moisture sensitivity level (MSL) 1 and supports lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated terminals are solderable per J-STD-002 and JESD 22-B102, and the M3 suffix confirms halogen-free, RoHS-compliant construction - making SMA6J13A-M3/5A suitable for modern high-reliability SMT assembly lines.
How does the M3 suffix differ from E3 in SMA6J13A-M3/5A?
The M3 suffix indicates halogen-free, RoHS-compliant construction meeting IEC 61249-2-21, whereas E3 denotes RoHS compliance without halogen-free certification. Both share identical electrical characteristics, thermal ratings, and package dimensions. For SMA6J13A-M3/5A, the M3 designation ensures suitability in environmentally regulated markets such as automotive and EU industrial equipment where halogen content is restricted.
What is the leakage current specification for SMA6J13A-M3/5A at its stand-off voltage?
SMA6J13A-M3/5A exhibits a maximum reverse leakage current (ID) of 0.2 μA at its 13 V stand-off voltage (VWM), measured at TA = 25 °C. This ultra-low leakage preserves signal integrity on sensitive analog or low-power digital lines and ensures minimal standby power loss - a key requirement for SMA6J13A-M3/5A deployment in battery-backed or energy-efficient systems.
Can SMA6J13A-M3/5A be used in bidirectional protection configurations?
No, SMA6J13A-M3/5A is unidirectional only, as explicitly stated in the Vishay datasheet. It conducts avalanche current only when cathode voltage exceeds anode voltage by ≥VBR. For bidirectional protection, two SMA6J13A-M3/5A devices must be connected in series opposition, or a dedicated bidirectional TVS (e.g., SMA6J13CA) should be selected - SMA6J13A-M3/5A is not rated or characterized for reverse-bias conduction.
