Product details
Overview
SMA6J10AHM3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, with 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR at IT = 1 mA), 15.7 V maximum clamping voltage (VC at IPP = 38.2 A, 10/1000 µs), 600 W peak pulse power (10/1000 µs), and 4 W power dissipation at TA = 50 °C. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the SMA6J10AHM3/61 datasheet, SMA6J10AHM3/61 pinout, SMA6J10AHM3/61 application, or SMA6J10AHM3/61 equivalent, key selection criteria include clamping voltage at rated surge current, unidirectional polarity, MSL level 1 compliance, halogen-free RoHS status (M3 suffix), and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This TVS diode operates as a voltage-clamped overvoltage protection device, triggered when reverse voltage exceeds its breakdown threshold (VBR). Its low dynamic resistance (RD = 0.089 Ω) ensures tight clamping performance under 10/1000 µs surges up to 38.2 A, limiting transient energy delivered to downstream circuitry.
Designed for surface-mount use on consumer, industrial, and telecom PCBs, it features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, meets UL 94 V-0 flammability rating, and supports reflow soldering at peak temperature of 260 °C per J-STD-020 MSL level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before conduction begins; defines safe signal line bias margin. |
| VBR (min/max) | 11.1 V / 12.3 V at IT = 1 mA - Confirmed breakdown range ensures predictable turn-on across production lots and temperature. |
| VC at IPP | 15.7 V at 38.2 A (10/1000 µs) - Clamping voltage directly limits stress on protected ICs during common lightning/inductive transients. |
| PPPM (10/1000 µs) | 600 W - Sustains standardized surge energy without failure; validates robustness for IEC 61000-4-5 Level 3 compliance designs. |
| PD @ TA = 50 °C | 4 W - Thermal derating enables reliable operation in enclosed industrial enclosures with limited airflow. |
| Polarity | Unidirectional - Protects only against negative transients relative to cathode; requires correct orientation in DC-biased circuits. |
| Package | SMA (DO-214AC) - Standardized footprint compatible with high-volume SMT assembly; 5.0 mm × 5.0 mm copper pads recommended per terminal. |
Pinout & Package
Two-terminal unidirectional TVS diode in SMA (DO-214AC) package. Cathode identified by color band. Mounting requires 5.0 mm × 5.0 mm copper pads per terminal for rated thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point during reverse surge | Connected to protected line; conducts surge current toward ground when Vreverse > VBR. |
| Cathode | Reference terminal; marked with color band | Typically tied to system ground or low-impedance return path; defines polarity and clamping reference. |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free, RoHS-compliant (M3) | Meets environmental compliance requirements for industrial and export markets without compromising thermal or electrical performance. |
| MSL level 1 moisture sensitivity | Enables direct placement after dry pack opening-no baking required-reducing manufacturing overhead and handling risk. |
| Low dynamic resistance (0.089 Ω) | Minimizes voltage overshoot during fast transients, improving protection margin for 3.3 V and 5 V logic interfaces. |
| UL 94 V-0 molding compound | Provides flame-retardant housing essential for safety-critical industrial and telecom infrastructure applications. |
Applications
| Motor Drive Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Suppresses voltage spikes generated by relay coil de-energization or H-bridge shoot-through in 24 V DC motor control modules. IC Role / Device Role / Timing Role: Unidirectional TVS placed across motor driver output pins to clamp inductive kickback below MOSFET VDS rating. Use Value: Prevents cumulative gate oxide damage and latch-up in half-bridge drivers by limiting transient voltage to ≤15.7 V at 38.2 A surge. | Use Scenario: Shields analog front-end inputs of pressure/temperature sensors connected to long cables in factory automation PLCs. IC Role / Device Role / Timing Role: Standoff protection element on 0–10 V or 4–20 mA signal lines exposed to ESD and nearby contactor switching noise. Use Value: Maintains signal integrity by holding leakage current ≤1 μA at 10 V while clamping 1 kV/500 A transients to <16 V. |
| Telecom Power Input | Consumer USB Port Protection |
Use Scenario: Guards 12 V DC input rails of VoIP gateways and DSL modems against lightning-induced surges entering via PoE or wall adapters. IC Role / Device Role / Timing Role: Primary-level transient suppressor upstream of DC-DC converters and LDOs, sized for 600 W (10/1000 µs) surge handling. Use Value: Absorbs full IEC 61000-4-5 combination wave energy without degradation, preserving downstream regulator reliability. | Use Scenario: Integrated into USB 2.0 Type-A port ESD protection stack on smart speaker mainboards to meet IEC 61000-4-2 ±15 kV air discharge. IC Role / Device Role / Timing Role: Secondary clamping device behind polymer PTC, providing low-VC backup for fast-rising ESD events. Use Value: Delivers 15.7 V clamping at 38.2 A with 0.089 Ω RD-lower overshoot than generic 12 V TVS-protecting USB PHY transceivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J10A-E3/61 | Same electrical specs, RoHS-compliant but not halogen-free; uses SnPb-free matte tin plating with E3 suffix. | Approved for industrial-grade use but lacks halogen-free certification required in some EU and automotive supply chains. | Select SMA6J10A-E3/61 if halogen-free content is not mandated and cost optimization is prioritized. |
| SMCJ10A-M3 | Higher power rating (1500 W, 10/1000 µs), larger SMC (DO-214AB) package, same VWM/VBR/VC specs. | Used where higher surge margin is needed (e.g., outdoor telecom cabinets); incompatible with SMA footprint. | Choose SMCJ10A-M3 only when board layout allows SMC footprint and 1500 W surge capability is required. |
Compared with SMA6J10A-E3/61, SMA6J10AHM3/61 adds halogen-free compliance without sacrificing clamping performance or thermal rating; versus SMCJ10A-M3, it trades surge capacity for space-constrained SMA packaging-critical for dense consumer PCBs.

FAQ
What is the maximum clamping voltage of the SMA6J10AHM3/61 under a 10/1000 µs surge?
The SMA6J10AHM3/61 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 using 5.0 mm × 5.0 mm copper pads per terminal and represents the upper bound of voltage seen by protected circuitry during standardized surge events.
Does the SMA6J10AHM3/61 support lead-free reflow soldering?
Yes, the SMA6J10AHM3/61 supports lead-free reflow soldering with a maximum peak temperature of 260 °C, meeting J-STD-020 MSL level 1 requirements. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, ensuring reliable wetting and intermetallic formation during standard SMT processes.
Is the SMA6J10AHM3/61 unidirectional or bidirectional?
The SMA6J10AHM3/61 is a unidirectional TVS diode, as confirmed in the Vishay datasheet under FEATURES and ELECTRICAL CHARACTERISTICS. It protects against negative transients only and must be oriented with the cathode band toward the ground or lower-potential node in the circuit.
What is the junction-to-ambient thermal resistance (RθJA) of the SMA6J10AHM3/61?
The typical junction-to-ambient thermal resistance (RθJA) of the SMA6J10AHM3/61 is 120 °C/W, measured under standard conditions with recommended PCB pad layout. This value informs thermal design margins when operating at elevated ambient temperatures or sustained power dissipation near its 4 W rating at TA = 50 °C.
How does the M3 suffix in SMA6J10AHM3/61 differ from the E3 suffix?
The M3 suffix indicates halogen-free, RoHS-compliant construction with JESD 201 class 2 whisker resistance, whereas E3 denotes RoHS-compliant but non-halogen-free material. Both share identical electrical specifications and SMA (DO-214AC) packaging, but M3 satisfies stricter environmental mandates in EU and certain industrial supply chains.
