Product details
Overview
SMA6J13A-TR from STMicroelectronics is a unidirectional 600 W transient voltage suppression (TVS) diode designed for IEC 61000-4-2 ESD and IEC 61000-4-4 surge protection in power rails and signal lines. It features a 13 V stand-off voltage (VRM), 20.4 V maximum clamping voltage at 29 A (8/20 µs), 0.2 µA leakage at 25 °C, and operates up to 175 °C junction temperature - deployed in industrial power supplies and automotive body control modules.
For engineers reviewing the SMA6J13A-TR datasheet, SMA6J13A-TR pinout, SMA6J13A-TR application, or SMA6J13A-TR equivalent, key selection criteria include clamping performance under 8/20 µs surges, low leakage at elevated temperatures, JEDEC DO-214AC (SMA) package compatibility with IPC-7531 footprints, and compliance with IEC 61000-4-2 level 4 (30 kV contact/air discharge).
Technical Context
This TVS diode uses planar silicon technology to achieve stable breakdown characteristics and low dynamic resistance (0.154 Ω at 8/20 µs), enabling precise voltage clamping during fast transients. Its unidirectional configuration supports DC-biased lines where reverse conduction must be blocked.
The device meets J-STD-020 MSL Level 1 moisture sensitivity and UL94 V0 flammability requirements, with matte tin-plated leads qualified per JESD 22-B102 E3 and MIL-STD-750 Method 2026 - ensuring robust solderability and long-term reliability in high-reliability PCB assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRM) | 13 V - maximum continuous reverse operating voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 14.4–15.9 V at 1 mA - ensures reliable triggering above normal rail voltage with margin |
| Clamping Voltage (VCL) | 20.4 V at 29 A (8/20 µs) - limits downstream IC stress during surge events |
| Peak Pulse Power | 600 W (10/1000 µs) - sustains typical lightning-induced surges in industrial interfaces |
| Leakage Current | 0.2 µA at 25 °C - minimizes standby power loss in battery-backed systems |
| Junction Temperature Range | −55 to +175 °C - supports operation in under-hood automotive or high-ambient industrial environments |
| Dynamic Resistance (RD) | 0.154 Ω - reduces clamping voltage rise under high-current transients |
Pinout & Package
The SMA6J13A-TR is housed in a JEDEC DO-214AC (SMA) surface-mount package with two terminals: anode and cathode. The package conforms to IPC-7531 footprint standards and supports reflow soldering per J-STD-020 Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Reverse-biased terminal in normal operation | Connected to ground or lower-potential node; conducts during positive transients on cathode side |
| Cathode (K) | Forward-biased terminal in normal operation | Connected to protected line (e.g., 12 V rail); clamps voltage by shunting surge current to ground |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 Level 4 Compliance | 30 kV air/contact discharge - exceeds standard immunity requirements for industrial end equipment |
| Low-Temperature Leakage Stability | 0.2 µA at 25 °C and 1 µA at 85 °C - preserves signal integrity in wide-temperature sensor interfaces |
| High Junction Temperature Rating | 175 °C max Tj - enables placement near heat sources without derating in motor drive PCBs |
| UL94 V0 Resin Encapsulation | Self-extinguishing polymer housing - satisfies fire-safety requirements in medical and building automation systems |
| Matte Tin Plated Leads | JEDEC JESD 22-B102 E3 qualified - ensures consistent wetting and void-free solder joints in automated assembly |

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-TR | Bidirectional version with symmetrical ±13 V standoff and identical clamping (20.4 V @ 29 A) | Required for AC-coupled or floating signal lines (e.g., RS-485, CAN) where polarity reversal occurs | Select when protecting bidirectional data lines; otherwise, SMA6J13A-TR offers lower leakage in DC-biased rails |
| SMBJ13A | Same VRM and VCL but in larger SMB (DO-214AA) package; 600 W rating, higher thermal mass | Preferred where board space allows and higher surge repetition tolerance is needed | Choose for designs requiring greater thermal cycling endurance or legacy SMB footprint compatibility |
Compared with SMA6J13CA-TR, SMA6J13A-TR provides lower leakage in DC applications; versus SMBJ13A, it trades package size for compactness while retaining full 600 W surge capability and identical electrical specs - making it optimal for space-constrained industrial PCBs.

FAQ
What is the maximum clamping voltage of SMA6J13A-TR under an 8/20 µs surge?
The maximum clamping voltage is 20.4 V at 29 A for an 8/20 µs waveform, measured at 25 °C ambient. This value increases with junction temperature per the αT coefficient (10⁻⁴/°C), reaching approximately 21.2 V at 125 °C junction temperature - critical for validating downstream IC voltage tolerances.
Does SMA6J13A-TR meet automotive qualification standards?
SMA6J13A-TR is not AEC-Q200 qualified, but its 175 °C maximum junction temperature, JESD22-A108 humidity testing compliance, and IEC 61000-4-2/4-4 certification make it suitable for non-safety-critical automotive applications such as body electronics and infotainment power rails - pending system-level validation per OEM requirements.
Can SMA6J13A-TR replace SMAJ13A in existing designs?
Yes - SMA6J13A-TR shares identical electrical specifications (VRM, VBR, VCL, PPP) and DO-214AC (SMA) package dimensions with SMAJ13A, but adds enhanced process control, UL94 V0 resin, and updated JEDEC registration. Footprint and solder profile are fully compatible per IPC-7531 and J-STD-020 Level 1.
What is the recommended PCB footprint for SMA6J13A-TR?
The recommended footprint matches IPC-7531 for DO-214AC: pad length 2.63 mm (0.104"), pad width 1.40 mm (0.055"), center-to-center spacing 5.43 mm (0.214"). Copper area ≥1.64 cm² per lead reduces thermal resistance to ≤4.5 °C/W, improving surge repetition capability.
