Product details
Overview
SMA6J10A-M3/61 from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor 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 max 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 - designed for protecting MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the SMA6J10A-M3/61 datasheet, SMA6J10A-M3/61 pinout, SMA6J10A-M3/61 application, or SMA6J10A-M3/61 equivalent, key selection criteria include verified clamping performance at 38.2 A surge current, unidirectional polarity confirmation, M3 halogen-free RoHS compliance, thermal resistance (RθJA = 120 °C/W), and compatibility with automated SMT placement on standard PCB pad layouts.
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 away from downstream components. Its dynamic resistance (RD = 0.089 Ω) ensures low clamping overshoot under 10/1000 μs pulses.
Designed for surface-mount reliability, it meets J-STD-020 MSL Level 1 (260 °C peak reflow), features matte tin-plated leads solderable per J-STD-002, and maintains stable VBR across temperature (αT = 7.8 × 10⁻⁴ /°C) - enabling predictable protection in environments up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC bias margin for protected circuit nodes. |
| VBR (min/max) | 11.1 V / 12.3 V at IT = 1 mA - guaranteed avalanche onset range; sets minimum overvoltage threshold for reliable triggering. |
| VC at IPP | 15.7 V at 38.2 A (10/1000 μs) - maximum clamped voltage during standardized surge; determines worst-case stress on downstream ICs. |
| PPPM (10/1000 μs) | 600 W - peak transient energy handling capacity; validates robustness against common inductive load-switching events. |
| RθJA | 120 °C/W - junction-to-ambient thermal resistance on 5.0 mm × 5.0 mm copper pads; informs derating requirements above TA = 50 °C. |
| Polarity | Unidirectional - cathode marked by band; enables asymmetric protection of positive-rail signals without forward conduction during normal operation. |
| IFSM | 50 A - non-repetitive forward surge rating (8.3 ms half-sine); supports brief fault-current tolerance during system startup or recovery. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with UL 94 V-0 flammability rating; cathode indicated by color band; terminals are matte tin-plated for J-STD-002-compliant soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path | Connected to ground or low-impedance reference; completes clamping loop during overvoltage events. |
| Cathode | Protected node connection point | Connected to line being protected (e.g., I/O, power rail); avalanche initiates here when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Clamping voltage control | VC = 15.7 V at 38.2 A ensures downstream ICs see ≤15.7 V during 10/1000 μs surges - critical for 3.3 V/5 V logic interface protection. |
| Halogen-free construction | M3 suffix confirms halogen-free, RoHS-compliant molding compound and terminations - satisfies IPC-1752A environmental compliance requirements. |
| Automated placement support | Low-profile SMA package with defined pad layout (0.074" × 0.208") enables high-yield pick-and-place assembly without tombstoning. |
| Thermal stability | VBR temperature coefficient αT = 7.8 × 10⁻⁴ /°C ensures <±5% VBR shift from -55 °C to +125 °C - maintains consistent trip point across operating range. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J10A-E3/61 | Same electrical specs, but E3 suffix indicates standard RoHS-compliant (non-halogen-free) construction; RθJA identical; same MSL Level 1 rating. | Approved for general industrial use where halogen-free requirement is not mandated; lower cost in non-automotive/medical BOMs. | Select SMA6J10A-E3/61 when halogen-free certification is unnecessary and cost optimization is prioritized. |
| SMB6J10A-M3/5A | Higher power rating (600 W same, but SMB package offers RθJA = 80 °C/W vs. 120 °C/W); larger footprint (DO-214AA); same VWM/VBR/VC specs. | Better thermal performance in high-ambient or high-duty-cycle surge environments; requires larger PCB area and different stencil design. | Choose SMB6J10A-M3/5A when sustained surge repetition or >70 °C ambient demands lower thermal resistance. |
Compared with SMA6J10A-E3/61, the SMA6J10A-M3/61 adds halogen-free compliance without sacrificing clamping performance or thermal specs; versus SMB6J10A-M3/5A, it trades thermal margin for space-constrained SMT layouts - making SMA6J10A-M3/61 optimal for compact industrial and telecom modules requiring full environmental compliance.

FAQ
What is the clamping voltage of the SMA6J10A-M3/61 under a 10/1000 μs surge?
The SMA6J10A-M3/61 has a maximum clamping voltage (VC) of 15.7 V at 38.2 A peak pulse current with a 10/1000 μs waveform. This value is measured per JEDEC standards and reflects worst-case voltage seen by protected circuitry during standardized surge testing - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings. The SMA6J10A-M3/61 achieves this with a dynamic resistance of 0.089 Ω.
Does the SMA6J10A-M3/61 support automated SMT assembly?
Yes, the SMA6J10A-M3/61 is explicitly designed for automated placement: its SMA (DO-214AC) package has low profile, defined pad layout (0.074" × 0.208"), matte tin-plated leads compliant with J-STD-002, and meets J-STD-020 MSL Level 1 (260 °C peak reflow). These features ensure high first-pass yield in high-speed pick-and-place processes - confirmed in Vishay's mechanical data and packaging notes for SMA6J10A-M3/61.
What is the difference between SMA6J10A-M3/61 and SMA6J10A-E3/61?
The SMA6J10A-M3/61 and SMA6J10A-E3/61 share identical electrical specifications (VWM = 10 V, VBR = 11.1–12.3 V, VC = 15.7 V), thermal resistance (RθJA = 120 °C/W), and packaging (SMA, 7" tape/reel). The sole difference is environmental compliance: M3 denotes halogen-free, RoHS-compliant construction, while E3 is RoHS-compliant but not halogen-free - making SMA6J10A-M3/61 suitable for strict automotive and medical supply chains.
What is the maximum operating temperature for the SMA6J10A-M3/61?
The SMA6J10A-M3/61 has an operating junction temperature range of -55 °C to +150 °C, with storage temperature matching that range. At TA = 50 °C, its power dissipation is rated at 4 W; derating follows Fig. 2 in the datasheet, where usable power drops linearly above 50 °C due to RθJA = 120 °C/W. This allows reliable operation in sealed industrial enclosures or under-hood automotive locations when mounted on recommended 5.0 mm × 5.0 mm copper pads.
Is the SMA6J10A-M3/61 unidirectional or bidirectional?
The SMA6J10A-M3/61 is unidirectional, as confirmed in the "FEATURES" section of the Vishay datasheet (Document Number: 89460) and the "Polarity" row of the Electrical Characteristics table. It features a cathode band marking and is intended for protection of positive-rail signals only - forward conduction occurs above ~1.2 V, but clamping action is specified only in reverse bias above VBR. Bidirectional variants (e.g., SMA6J10CA) are separate part numbers.
