Product details
Overview
SMA6J130A-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 electrical fast transient protection in power rails and signal lines. It features a 13 V stand-off voltage (VRM), 20.4 V clamping voltage at 29 A (10/1000 µs), and operates up to +175 °C junction temperature. Used in industrial power supplies, automotive body control modules, and telecom interface protection.
For engineers reviewing the SMA6J130A-TR datasheet, SMA6J130A-TR pinout, SMA6J130A-TR application, or SMA6J130A-TR equivalent, key selection criteria include clamping voltage vs. peak pulse current, leakage current at elevated temperature, JEDEC DO-214AC (SMA) package thermal performance, 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 low leakage (≤1 µA at 85 °C) and high thermal stability across -55 °C to +175 °C operating junction range. Its unidirectional configuration provides asymmetric clamping-low forward voltage drop (~1.2 V at 1 A) and high reverse breakdown precision (14.4–15.9 V at 1 mA).
The device meets JEDEC 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. Dynamic resistance is 0.154 Ω (10/1000 µs), enabling predictable voltage clamping under surge conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J13A-TR | Identical electrical specs and package; same VRM, VBR, VCL, and PPP ratings | No functional difference - identical marking and ordering code per ST documentation | Select based on inventory availability; no design change required |
| P6SMB13A-T | Same 13 V VRM but higher VCL (21.5 V @ 27.2 A), lower PPP (600 W), and larger SMB package (DO-214AA) | Larger footprint and 10% higher clamping voltage reduce margin for 3.3 V/5 V logic protection | Prefer SMA6J130A-TR where space-constrained layouts or tighter clamping is required |
Compared with SMA6J13A-TR (identical spec), SMA6J130A-TR offers no deviation; versus P6SMB13A-T, it delivers lower clamping voltage in a smaller DO-214AC package, improving board density and surge margin in high-reliability designs.

FAQ
What is the maximum clamping voltage of SMA6J130A-TR under a 10/1000 µs surge?
The maximum clamping voltage is 20.4 V at 29 A for a 10/1000 µs waveform, measured at Tj = 25 °C. This value increases linearly with junction temperature due to the αT coefficient of 10−4/°C, reaching ~21.3 V at 125 °C.
Is SMA6J130A-TR bidirectional or unidirectional?
SMA6J130A-TR is unidirectional, indicated by the "A" suffix (versus "CA" for bidirectional). It conducts only in reverse bias above VBR, with forward voltage drop ≤1.2 V at 1 A, making it suitable for DC rail protection where polarity is fixed.
Does this TVS diode require special handling for moisture sensitivity?
No - SMA6J130A-TR is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and does not require dry packing, baking, or humidity-controlled storage before reflow soldering.
How does the DO-214AC (SMA) package compare thermally to DO-214AA (SMB)?
The DO-214AC package has lower thermal resistance than DO-214AA due to shorter lead lengths and optimized copper pad layout. At 1 cm² copper area per lead, Rth(j-a) is ~120 °C/W for SMA versus ~145 °C/W for SMB, improving power dissipation capability in compact layouts.
