Product details
Overview
SMA6J10A-E3/5A from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) in SMA (DO-214AC) package, with 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 15.7 V max clamping voltage at 38.2 A (10/1000 μs), 600 W peak pulse power rating, and 150 °C max junction temperature - used to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the SMA6J10A-E3/5A datasheet, SMA6J10A-E3/5A pinout, SMA6J10A-E3/5A application, or SMA6J10A-E3/5A equivalent, key selection criteria include clamping voltage margin vs. protected device's absolute maximum rating, unidirectional polarity compatibility with DC-biased lines, thermal resistance (RθJA = 120 °C/W), and 13" tape-and-reel packaging for high-volume SMT assembly.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (11.1–12.3 V), it avalanches to limit transient energy by diverting surge current to ground. Its low dynamic resistance (0.089 Ω) ensures tight clamping under 10/1000 μs surges up to 38.2 A, while maintaining <5 μA leakage at 10 V stand-off.
Designed for PCB-level protection of DC-powered interfaces, it features MSL Level 1 moisture sensitivity, matte tin-plated leads compliant with J-STD-002, and UL 94 V-0 molding compound - enabling reliable reflow soldering without pre-baking and long-term stability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse voltage before significant leakage; sets upper limit for safe operation on 9–10 V DC rails. |
| VBR (min/max) | 11.1 V / 12.3 V - Breakdown onset range at 1 mA test current; defines minimum overvoltage threshold for clamping activation. |
| VC @ IPP | 15.7 V at 38.2 A (10/1000 μs) - Clamped voltage during standard surge; must be below protected IC's absolute max rating. |
| PPPM (10×1000 μs) | 600 W - Peak transient energy handling capacity; determines survivability against common inductive load-switching events. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance on standard 5 mm × 5 mm copper pads; governs derating above 25 °C ambient. |
| Polarity | Unidirectional - Cathode-banded configuration; suitable only for DC lines with fixed polarity, not AC or bidirectional data lines. |
| Package | SMA (DO-214AC) - Surface-mount outline with 2.54 mm lead pitch; compatible with automated pick-and-place and IR/reflow processes. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with cathode band marking; dimensions: 4.50 mm × 2.79 mm × 2.20 mm (L × W × H); terminals are matte tin-plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to ground or low-impedance return plane; completes shunt path during avalanche conduction. |
| Cathode | Protected line connection | Connected to the line being protected (e.g., VCC or signal); color band identifies this terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Clamping performance | 15.7 V max VC at 38.2 A ensures robust protection margin for 12 V systems with ±10 % tolerance. |
| Surge waveform support | Rated for both 10/1000 μs (600 W) and 8/20 μs (4000 W) transients - covers IEC 61000-4-5 and ISO 7637-2 threats. |
| Thermal reliability | 150 °C max TJ and 120 °C/W RθJA enable stable operation in enclosed industrial enclosures up to 75 °C ambient. |
| Manufacturing readiness | MSL Level 1 rating and 260 °C peak reflow compatibility eliminate pre-bake requirements and support high-yield SMT 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 |
|---|---|---|---|
| SMA6J10CA-E3/5A | Bidirectional variant; symmetric clamping for AC or floating lines; same VBR, VC, and power ratings. | Required where protected line lacks defined DC bias (e.g., RS-485, CAN bus), unlike SMA6J10A-E3/5A's unidirectional use. | Select SMA6J10CA-E3/5A only if bidirectional surge immunity is needed; otherwise SMA6J10A-E3/5A offers lower cost and simpler layout. |
| SMCJ10A-E3/57T | Higher power rating (1500 W PPPM @ 10/1000 μs); larger SMC (DO-214AB) package; same VWM/VBR/VC specs. | Used where higher surge energy (e.g., outdoor power supplies) exceeds SMA6J10A-E3/5A's 600 W limit; requires larger PCB footprint. | Choose SMCJ10A-E3/57T when design faces >600 W transients; retain SMA6J10A-E3/5A for space-constrained 600 W-class protection. |
Compared with SMA6J10CA-E3/5A and SMCJ10A-E3/57T, the SMA6J10A-E3/5A provides optimal balance of compact SMA footprint, 600 W surge capability, and cost efficiency for unidirectionally biased 12 V DC protection - making it ideal for dense industrial PCBs where board area and polarity certainty are prioritized.

FAQ
What is the maximum clamping voltage of the SMA6J10A-E3/5A under a 10/1000 μs surge?
The SMA6J10A-E3/5A has a maximum clamping voltage (VC) of 15.7 V at 38.2 A under a 10/1000 μs waveform. This value is measured per the manufacturer's test conditions and ensures predictable voltage limiting during standardized surge events. The SMA6J10A-E3/5A maintains this clamping performance across its specified operating temperature range when mounted per recommended pad layout.
Is the SMA6J10A-E3/5A suitable for protecting bidirectional communication lines like RS-485?
No, the SMA6J10A-E3/5A is unidirectional only and must not be used on AC-coupled or floating bidirectional lines. For RS-485 or CAN bus protection, use the bidirectional variant SMA6J10CA-E3/5A instead. The SMA6J10A-E3/5A's cathode-band polarity restricts it to DC-biased applications where the protected line remains positive relative to ground.
What is the leakage current specification for SMA6J10A-E3/5A at its stand-off voltage?
At the 10 V stand-off voltage (VWM), the SMA6J10A-E3/5A exhibits a maximum reverse leakage current (ID) of 5 μA at 25 °C. This low leakage preserves power efficiency in battery-operated or always-on systems and ensures minimal loading on sensitive sensor or reference circuits powered from the same rail protected by the SMA6J10A-E3/5A.
Does SMA6J10A-E3/5A require pre-baking before reflow soldering?
No, the SMA6J10A-E3/5A is rated MSL Level 1 per J-STD-020 and qualified for peak reflow temperatures up to 260 °C, eliminating the need for pre-baking. Its moisture-sensitive level and lead finish comply fully with standard SMT assembly processes, enabling direct placement and reflow without additional handling steps - a key advantage confirmed in the Vishay datasheet revision 09-Jan-2024.
How does the thermal resistance of SMA6J10A-E3/5A affect its power derating?
The SMA6J10A-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W on standard 5 mm × 5 mm copper pads. At 50 °C ambient, its power dissipation must be derated from 4.0 W (rated at TA = 50 °C) downward per the curve in Figure 2 of the datasheet; exceeding this limit risks thermal runaway during sustained surge exposure. Proper PCB copper area is essential to maintain SMA6J10A-E3/5A reliability.
