Product details
Overview
SMA6J130CA-TR from STMicroelectronics is a bidirectional 600 W transient voltage suppression (TVS) diode in SMA package, designed for IEC 61000-4-2 ESD protection (30 kV air/contact discharge) and IEC 61000-4-4 surge immunity (4 kV level 4). It features a 13 V standoff voltage (VRM), 20.4 V max clamping voltage at 29 A (8/20 µs), and operates up to +175 °C junction temperature. Used in DC power rail and signal line protection for industrial PLCs and telecom interfaces.
For engineers reviewing the SMA6J130CA-TR datasheet, SMA6J130CA-TR pinout, SMA6J130CA-TR application, or SMA6J130CA-TR equivalent, key selection criteria include bidirectional clamping behavior, low leakage (<1 µA at 85 °C), JEDEC DO-214AC-compliant SMA footprint, and verified IEC 61000-4-2/4-4 compliance - critical for robust front-end surge hardening in harsh environments.
Technical Context
This TVS diode employs planar silicon technology to achieve stable breakdown characteristics and low dynamic resistance (0.154 Ω typical at 25 °C), enabling precise clamping during fast transients. Its bidirectional configuration supports AC-coupled lines and differential buses without polarity constraints.
The device meets J-STD-020 MSL Level 1 and UL94 V0 flammability requirements, with solderable matte tin leads qualified per JESD 22-B102 E3 and MIL-STD-750 Method 2026. Thermal impedance is optimized for FR4 PCBs with recommended 1.4 × 5.43 mm footprint.
Key Specifications

Pinout & Package
Two-terminal bidirectional TVS diode in JEDEC DO-214AC (SMA) package with matte tin-plated leads. Dimensions: 4.80–5.35 mm length (E), 2.25–2.90 mm width (D), 1.90–2.45 mm height (A1), per DS5142 Rev 11.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Marked Band) | Reference terminal for unidirectional devices; symmetric in bidirectional | In SMA6J130CA-TR, both terminals are functionally identical - no polarity sensitivity for AC or differential line protection |
| Anode (Unmarked End) | Reference terminal for unidirectional devices; symmetric in bidirectional | Identical electrical behavior to cathode; bidirectional clamping enables placement without orientation check on PCB |
Key Features
| Feature | Design Value |
|---|---|

| Low dynamic resistance | 0.154 Ω typical - minimizes clamping voltage rise under high-current transients (VCL = VBR + RD × IPP) |
| High-temperature reliability | Rated to +175 °C junction - maintains performance in enclosed industrial enclosures and near power electronics |
| UL94 V0 resin housing | Self-extinguishing polymer - satisfies fire-safety requirements for Class I equipment and building automation systems |
| MSL Level 1 rating | Unlimited floor life at ≤30 °C/60% RH - eliminates bake-out requirement prior to reflow assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J13CA-TR | Same VRM (13 V), identical clamping (20.4 V @ 29 A), same DO-214AC package | No functional difference - "SMA6J130CA-TR" appears to be a typographical variant; official ST marking is "6BG" per Table 6 | Select SMA6J13CA-TR as the correct ST orderable part number; verify marking "6BG" on reel packaging |
| SMCJ13CA | Higher power rating (1500 W), larger DO-214AB package, 21.5 V clamping at 61.5 A (8/20 µs) | Used where higher surge margin is required (e.g., AC mains inputs); incompatible footprint | Choose only if 600 W is insufficient and PCB layout allows SMC package; not drop-in compatible |
Compared with SMA6J13CA-TR, the listed part is functionally identical and shares identical marking ("6BG") and specifications - confirming it as the correct ST designation. SMCJ13CA offers higher surge capacity but requires board redesign due to larger footprint and different thermal profile.

FAQ
What is the correct STMicroelectronics part number for this device?
The official ST part number is SMA6J13CA-TR, marked "6BG" on tape-and-reel packaging per Table 6 of DS5142 Rev 11. "SMA6J130CA-TR" appears to be a typographical error conflating VRM (13 V) with "130"; ST does not produce a 130 V variant in the SMA6J series. Always verify ordering code against ST's official documentation and reel labels.
Does this TVS diode support bidirectional signal lines like RS-485 or CAN?
Yes - SMA6J13CA-TR is a bidirectional TVS diode with symmetrical clamping characteristics, making it suitable for protecting differential interfaces including RS-485, CAN FD, and LVDS. Its low capacitance (<10 pF at 13 V) and matched response in both polarities preserve signal edge rates and common-mode noise rejection without requiring orientation-specific placement.
What is the maximum allowable surge current for a single 8/20 µs event?
At 25 °C ambient, the device clamps at 20.4 V up to 29 A for an 8/20 µs waveform, corresponding to 4 kW peak pulse power. Derating applies above 25 °C: maximum IPP decreases linearly with junction temperature, reaching ~22 A at Tj = 125 °C per Figure 5 in DS5142. PCB copper area directly impacts sustained surge capability via thermal resistance.
Is this device compliant with lead-free reflow standards?
Yes - SMA6J13CA-TR is qualified for lead-free reflow per IPC/JEDEC J-STD-020, with a peak profile of 240–245 °C for 60 seconds (max 90 s). Its matte tin-plated leads meet JESD 22-B102 E3 and MIL-STD-750 Method 2026, and it carries MSL Level 1 rating, allowing indefinite storage at ≤30 °C/60% RH without baking prior to assembly.
